The most common terms include <strong>plain BOPP, coated BOPP, treated BOPP, untreated BOPP, heat-sealable BOPP, and non-heat-sealable BOPP<\/strong>. These terms describe different properties, and one BOPP film can belong to more than one category at the same time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a film can be <strong>plain and treated<\/strong>, or <strong>coated and heat-sealable<\/strong>. Understanding this difference helps buyers choose the correct BOPP film for printing, lamination, packaging, labeling, and other converting processes.<\/p>\n\n\n\n<figure data-spectra-id=\"spectra-msmuikpz-e9x8ao\" class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"400\" src=\"https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/bopp-films-types.jpg\" alt=\"BOPP film classification guide showing six framed samples of plain, coated, treated, untreated, heat-sealable and non-heat-sealable BOPP films around a central film roll\" class=\"wp-image-3354\" title=\"BOPP Film Types Explained: Plain, Coated, Treated, Heat-Sealable and More\" srcset=\"https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/bopp-films-types.jpg 600w, https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/bopp-films-types-300x200.jpg 300w, https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/bopp-films-types-18x12.jpg 18w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Is BOPP Film?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">BOPP stands for <strong><a href=\"https:\/\/szfilmfactory.com\/ru\/blog\/eva-in-bopp-film-thermal-lamination\/\" target=\"_blank\" rel=\"noreferrer noopener\">Biaxially Oriented Polypropylene<\/a><\/strong>. It is a polypropylene film stretched in both the machine direction and transverse direction to improve its physical properties.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BOPP film is widely used because it offers a good balance of <strong>clarity, stiffness, strength, moisture resistance, and printability<\/strong>. It is commonly used in flexible packaging, labels, lamination, overwrap, and industrial applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The final performance of BOPP film depends on more than the base material. Film structure, orientation, surface treatment, coating, thickness, and sealing properties can all affect the final application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>In simple terms, BOPP film is a versatile base film that can be modified for different converting and packaging requirements.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">BOPP Film Classification at a Glance<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The easiest way to understand BOPP film types is to classify them by the property being described.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Classification<\/th><th>What it describes<\/th><th>Typical purpose<\/th><\/tr><\/thead><tbody><tr><td>Plain BOPP<\/td><td>Basic film surface or structure<\/td><td>Printing, lamination, general converting<\/td><\/tr><tr><td>Coated BOPP<\/td><td>Film with an additional coating<\/td><td>Special surface or functional performance<\/td><\/tr><tr><td>Treated BOPP<\/td><td>Surface has been treated<\/td><td>Better ink, adhesive, or coating adhesion<\/td><\/tr><tr><td>Untreated BOPP<\/td><td>Surface has no such surface treatment<\/td><td>Applications where treatment is not required<\/td><\/tr><tr><td>Heat-sealable BOPP<\/td><td>Designed to seal under heat<\/td><td>Packaging that needs direct heat sealing<\/td><\/tr><tr><td>Non-heat-sealable BOPP<\/td><td>Does not provide a heat-sealing layer<\/td><td>Lamination and applications using another sealing layer<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>These categories can overlap.<\/strong> For example, plain BOPP can be corona treated, while a coated BOPP can also have heat-sealing properties.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">1. <a href=\"https:\/\/szfilmfactory.com\/ru\/films\/basic-lamination-films\/\" target=\"_blank\" rel=\"noreferrer noopener\">Plain BOPP Film<\/a><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Plain BOPP film is a basic BOPP film without a special functional coating or decorative surface finish.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The word <strong>\u201cplain\u201d<\/strong> does not mean that the film is untreated. It usually describes the film as a standard or basic BOPP structure rather than a film with a special coating, matte effect, or other functional layer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plain BOPP can be transparent and glossy, depending on the film grade and production process. It is commonly selected as a base film for printing, lamination, labeling, and other converting processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A plain BOPP film may still receive <a href=\"https:\/\/szfilmfactory.com\/ru\/blog\/bopp-film-corona-treatment\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>corona treatment<\/strong> <\/a>on one or both sides. Therefore, \u201cplain\u201d and \u201cuntreated\u201d should not be treated as opposite terms.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Common applications of plain BOPP<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Plain BOPP film can be used for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Flexible packaging<\/li>\n\n\n\n<li>Lamination<\/li>\n\n\n\n<li>Printing<\/li>\n\n\n\n<li>Labels<\/li>\n\n\n\n<li>Overwrap<\/li>\n\n\n\n<li>General converting applications<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Choose plain BOPP when you need a standard film structure and do not need a special surface coating.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are looking for a BOPP film for a specific printing or lamination process, you can also explore our <strong><a href=\"https:\/\/szfilmfactory.com\/ru\/films\/\" target=\"_blank\" rel=\"noreferrer noopener\">BOPP film products<\/a><\/strong> to find a suitable film grade.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2. <a href=\"https:\/\/szfilmfactory.com\/ru\/films\/functional-protective-films\/\" target=\"_blank\" rel=\"noreferrer noopener\">Coated BOPP Film<\/a><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Coated BOPP film has an additional coating applied to the film surface to provide a specific function or surface property.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The coating can change how the film interacts with ink, adhesive, heat, light, or the surrounding environment. The exact performance depends on the coating material and coating process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Coated BOPP can be designed for applications where standard BOPP does not provide the required surface performance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why use coated BOPP?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A coating may be used to improve or add properties such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Printability<\/li>\n\n\n\n<li><a href=\"https:\/\/szfilmfactory.com\/ru\/blog\/digital-lamination-film-for-xerox-hp-indigo\/\" target=\"_blank\" rel=\"noreferrer noopener\">Ink adhesion<\/a><\/li>\n\n\n\n<li>Adhesive compatibility<\/li>\n\n\n\n<li>Heat-sealing performance<\/li>\n\n\n\n<li>Surface appearance<\/li>\n\n\n\n<li>Barrier performance<\/li>\n\n\n\n<li>Special tactile or functional effects<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The term <strong>\u201ccoated\u201d does not describe one specific product<\/strong>. Different coatings are developed for different applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a coating designed for high-quality printing is different from a coating designed for heat sealing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Coated vs. plain BOPP<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The main difference is simple:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Plain BOPP is a basic film structure, while coated BOPP has an additional coating designed to provide specific surface or functional properties.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For applications that require special surface performance, a coated film may be a better choice than standard BOPP.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3. Treated BOPP Film<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Treated BOPP film has a modified surface that improves adhesion to inks, coatings, or adhesives.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Polypropylene has relatively low surface energy. This can make it difficult for some inks and adhesives to bond strongly to untreated film.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A common solution is <strong><a href=\"https:\/\/szfilmfactory.com\/ru\/blog\/bopp-film-corona-treatment\/\" target=\"_blank\" rel=\"noreferrer noopener\">corona treatment<\/a><\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Corona treatment uses electrical discharge to modify the film surface. This can increase surface energy and improve the interaction between the film and materials applied to it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is BOPP film treated?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Treated BOPP is commonly used when the film needs to work with:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Printing inks<\/li>\n\n\n\n<li>Adhesives<\/li>\n\n\n\n<li>Coatings<\/li>\n\n\n\n<li>Lamination systems<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a printer may need treated BOPP because ink needs to wet and adhere properly to the film surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Treated BOPP does not always mean coated BOPP<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Treatment and coating are different processes.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Surface treatment modifies the surface of the existing film. Coating adds another material or layer to the surface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This distinction is important when selecting film for printing or lamination.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">4. Untreated BOPP Film<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Untreated BOPP film has not received a surface treatment such as corona treatment on the specified surface.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Untreated BOPP generally has lower surface energy than treated BOPP. As a result, inks, adhesives, and coatings may have difficulty bonding to the surface without additional preparation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, untreated film can still be useful in applications where direct printing or coating is not required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It may also be used as part of a multilayer structure where another layer provides the required adhesion or functional performance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Treated vs. untreated BOPP<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The basic difference is surface condition:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Feature<\/th><th>Treated BOPP<\/th><th>Untreated BOPP<\/th><\/tr><\/thead><tbody><tr><td>Surface treatment<\/td><td>Yes<\/td><td>No<\/td><\/tr><tr><td>Surface energy<\/td><td>Usually higher<\/td><td>Usually lower<\/td><\/tr><tr><td>Ink adhesion<\/td><td>Generally better<\/td><td>Generally more difficult<\/td><\/tr><tr><td>Adhesive bonding<\/td><td>Generally easier<\/td><td>May require additional treatment<\/td><\/tr><tr><td>Typical use<\/td><td>Printing and lamination<\/td><td>Applications without direct printing\/coating<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The correct choice depends on what will contact the BOPP surface during converting.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When ordering BOPP film, buyers should confirm <strong>which side is treated and the required surface treatment level<\/strong>, rather than only asking whether the film is \u201ctreated.\u201d<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">5. Heat-Sealable BOPP Film<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Heat-sealable BOPP film is designed to form a seal when heat and pressure are applied under suitable sealing conditions.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This type of film is useful for packaging structures that need the film itself to participate in the sealing process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many heat-sealable BOPP films use a multilayer structure. The sealing layer is designed to soften and form a bond at the required sealing temperature.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Where is heat-sealable BOPP used?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Common applications include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Flexible food packaging<\/li>\n\n\n\n<li>Snack packaging<\/li>\n\n\n\n<li>Overwrap<\/li>\n\n\n\n<li>Bags and pouches<\/li>\n\n\n\n<li>Packaging structures that require heat sealing<\/li>\n<\/ul>\n\n\n\n<figure data-spectra-id=\"spectra-msmu61nv-6qkuec\" class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/Heat-sealable-BOPP-application.jpg\" alt=\"Heat Sealable BOPP film applications showcase with central film roll surrounded by framed packages of snacks, biscuits, candy, instant noodles, frozen food, tissue, flower sleeves, stationery and straws\" class=\"wp-image-3353\" title=\"BOPP Film Types Explained: Plain, Coated, Treated, Heat-Sealable and More\" srcset=\"https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/Heat-sealable-BOPP-application.jpg 500w, https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/Heat-sealable-BOPP-application-300x300.jpg 300w, https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/Heat-sealable-BOPP-application-150x150.jpg 150w, https:\/\/szfilmfactory.com\/wp-content\/uploads\/2026\/08\/Heat-sealable-BOPP-application-12x12.jpg 12w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Heat-sealable BOPP can simplify packaging design because the film can provide both the main film properties and the sealing function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, sealing performance depends on more than the film name. <strong>Sealing temperature, pressure, dwell time, sealing layer, packaging machine, and film structure can all affect the final seal.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, buyers should select a film based on the actual packaging process rather than choosing a film only because it is labeled \u201cheat-sealable.\u201d<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">6. Non-Heat-Sealable BOPP Film<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Non-heat-sealable BOPP film is generally used when the BOPP layer itself does not need to provide the final heat seal.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This does not mean that a package made with non-heat-sealable BOPP cannot be heat sealed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead, another layer in the packaging structure may provide the sealing function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, BOPP can be laminated with another film that has suitable heat-sealing properties. In this structure, the BOPP layer can provide properties such as stiffness, clarity, printability, or appearance, while another layer provides the seal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why use non-heat-sealable BOPP?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Non-heat-sealable BOPP can be suitable for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lamination<\/li>\n\n\n\n<li>Printed packaging structures<\/li>\n\n\n\n<li>Label applications<\/li>\n\n\n\n<li>Structures where another layer provides heat sealing<\/li>\n\n\n\n<li>Applications where direct heat sealing of BOPP is not required<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The key point is that non-heat-sealable BOPP is not necessarily \u201cless useful\u201d; it is designed for a different packaging structure.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Plain vs. Coated BOPP: What Is the Difference?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Plain BOPP is a basic film structure, while coated BOPP contains an additional coating for a specific surface or functional requirement.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plain BOPP is often selected when the converter needs a standard film for printing, lamination, or general processing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Coated BOPP is more suitable when the surface needs additional functionality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The right choice depends on the next processing step.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For standard converting \u2192 plain BOPP may be suitable.<\/li>\n\n\n\n<li>For special printing requirements \u2192 coated BOPP may be considered.<\/li>\n\n\n\n<li>For special surface performance \u2192 a functional coating may be required.<\/li>\n\n\n\n<li>For lamination \u2192 the correct surface treatment or coating is important.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Do not choose between plain and coated BOPP based only on appearance. Check the required converting process first.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Treated vs. Untreated BOPP: What Is the Difference?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The main difference between treated and untreated BOPP is the condition of the film surface, especially its ability to accept inks, coatings, or adhesives.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Treated BOPP is commonly preferred for printing and lamination because surface treatment can improve adhesion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Untreated BOPP may be suitable when no direct printing, coating, or adhesive bonding is required on that surface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One important point is that <strong>surface treatment can change over time<\/strong>. Storage conditions, contamination, and film age can affect surface performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For demanding printing or lamination applications, converters should confirm the supplier&#8217;s recommended treatment level and test the film under actual production conditions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Heat-Sealable vs. Non-Heat-Sealable BOPP<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The key difference is whether the film structure is designed to provide a heat-sealing function.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Heat-sealable BOPP normally includes a sealing layer or structure that can create a seal under suitable heat, pressure, and time conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Non-heat-sealable BOPP does not normally provide that direct sealing function. It can instead be combined with another heat-sealable material.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The choice depends on the packaging machine and the complete packaging structure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Quick comparison<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Property<\/th><th>Heat-Sealable BOPP<\/th><th>Non-Heat-Sealable BOPP<\/th><\/tr><\/thead><tbody><tr><td>Direct heat sealing<\/td><td>Yes, under suitable conditions<\/td><td>No, normally<\/td><\/tr><tr><td>Sealing layer<\/td><td>Usually included<\/td><td>Usually not included<\/td><\/tr><tr><td>Typical use<\/td><td>Heat-sealed packaging<\/td><td>Printing, lamination, and multilayer structures<\/td><\/tr><tr><td>Main selection factor<\/td><td>Sealing performance<\/td><td>Converting and lamination requirements<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How BOPP Film Types Can Overlap<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>BOPP classification terms describe different aspects of the film, so one film can have several classifications at the same time.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is one of the most important points when buying BOPP film.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Plain + Treated + Non-Heat-Sealable<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This could describe a standard BOPP film that has a treated printing surface but does not provide a direct heat-sealing function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another film could be:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Coated + Treated + Heat-Sealable<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This could describe a film with a functional coating, surface treatment, and sealing structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, it is not correct to think of plain, coated, treated, untreated, heat-sealable, and non-heat-sealable as six completely separate BOPP product groups.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>They describe different characteristics of the same film.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How to Choose the Right BOPP Film<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The best BOPP film should be selected according to the final application, converting process, and required performance.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Start with the final use instead of starting with the film name.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Check the final application<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ask where the film will be used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Is it for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Food packaging?<\/li>\n\n\n\n<li>Labels?<\/li>\n\n\n\n<li>Lamination?<\/li>\n\n\n\n<li>Printing?<\/li>\n\n\n\n<li>Overwrap?<\/li>\n\n\n\n<li>Industrial packaging?<\/li>\n\n\n\n<li>Decorative applications?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The application determines the basic film requirements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Check whether printing is required<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>If the film will be printed directly, surface treatment is usually an important consideration.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The required treatment depends on the ink, printing method, and production conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Check whether lamination is required<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>If BOPP will be laminated, the surface must be compatible with the selected adhesive and lamination process.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A treated or specially coated surface may be required depending on the structure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Check whether heat sealing is required<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>If the BOPP film must form the package seal, choose a suitable heat-sealable grade.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If another layer provides the seal, a non-heat-sealable BOPP may be suitable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5.

Untreated refers to the absence of a specified surface treatment. A plain BOPP film can still be treated.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is coated BOPP better than plain BOPP?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Not necessarily.<\/strong> Coated BOPP is designed for additional functionality, while plain BOPP can be the better choice for applications that do not require a special coating. The correct film depends on the application.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can treated BOPP be used for printing?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Yes.<\/strong> Treated BOPP is commonly used for printing because surface treatment can improve ink adhesion. The actual result depends on the treatment level, ink system, printing process, and storage conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can non-heat-sealable BOPP be used for packaging?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Yes.<\/strong> Non-heat-sealable BOPP can be part of a multilayer packaging structure. Another layer can provide the heat-sealing function.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the difference between BOPP and heat-sealable BOPP?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Standard BOPP does not necessarily provide direct heat sealing, while heat-sealable BOPP is designed with a sealing structure that can form a seal under suitable conditions.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which BOPP film is best for lamination?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The best BOPP film for lamination depends on the adhesive, lamination process, printing requirements, and final packaging structure.<\/strong> In many cases, surface treatment is an important factor because the adhesive needs sufficient adhesion to the film.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Why Choose the Right BOPP Film Supplier?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A reliable BOPP film supplier should help you match film properties with your actual converting process.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At <strong>SZ Film Factory<\/strong>, we focus on BOPP and PET film solutions for different converting and packaging needs.
