BOPP touch film is commonly produced with one oil coating, while SZ Film Factory uses two oil coating passes for our high-end touch film.<\/strong> This extra coating step gives us more control over the surface feel, coating uniformity, and final appearance of the film.<\/p>\n\n\n\n

What Is BOPP Touch Film?<\/h2>\n\n\n\n

BOPP touch film<\/a> is BOPP film with a special surface coating that creates a soft and premium touch.<\/strong> BOPP stands for biaxially oriented polypropylene. It offers good strength, clarity, and dimensional stability.<\/p>\n\n\n\n

The touch coating changes the surface experience of the film. It can give packaging and printed products a smoother, softer, and more premium feel.<\/p>\n\n\n\n

Our BOPP Touch Film<\/a><\/strong> is designed for applications where surface feel is an important part of the product experience.<\/p>\n\n\n\n

How Is BOPP Touch Film Made?<\/h2>\n\n\n\n

The production process includes BOPP film preparation, surface treatment, oil coating, drying, and quality inspection.<\/strong> The basic process is similar across many touch film products, but coating methods can differ between manufacturers.<\/p>\n\n\n\n

For standard production, one oil coating is commonly used<\/strong> to create the required touch effect. At SZ Film Factory, we take a different approach for our high-end touch film.<\/p>\n\n\n\n

1. BOPP Base Film Preparation<\/h3>\n\n\n\n

A stable BOPP base film provides the foundation for the final touch film.<\/strong> The film must have consistent thickness, good flatness, and a clean surface before coating.<\/p>\n\n\n\n

The base film is first unwound and prepared for the coating process.<\/p>\n\n\n\n

2. Surface Treatment<\/h3>\n\n\n\n

Surface treatment helps the coating bond properly with the BOPP film.<\/strong> A suitable surface energy is important for coating adhesion and long-term stability.<\/p>\n\n\n\n

Corona treatment<\/a><\/strong> is commonly used to improve the surface before coating.<\/p>\n\n\n\n

3. First Oil Coating<\/h3>\n\n\n\n

The first oil coating creates the initial functional coating layer.<\/strong> The coating is applied evenly while controlling coating weight, line speed, and drying conditions.<\/p>\n\n\n\n

After coating, the film passes through the drying system to stabilize the first layer.<\/p>\n\n\n\n

4. Second Oil Coating<\/h3>\n\n\n\n

The key difference in our high-end touch film is the second oil coating.<\/strong> While one coating is commonly enough for standard touch film production, we apply the oil twice<\/strong> for our high-end products.<\/p>\n\n\n\n

The second coating gives us another opportunity to control the final surface characteristics. It helps us achieve the touch, appearance, and consistency required for premium applications.<\/p>\n\n\n\n

Two coating passes do not simply mean \u201cmore coating.\u201d<\/strong> The process requires careful control of coating weight, drying temperature, coating speed, and the interaction between the two layers.<\/p>\n\n\n\n

This is an important part of our high-end BOPP touch film production.<\/p>\n\n\n\n

Industry approach:<\/strong> One oil coating is commonly used for BOPP touch film.
SZ Film Factory approach:<\/strong> Two oil coating passes are used for our high-end touch film.<\/p>\n<\/blockquote>\n\n\n\n

Why Do We Use Two Oil Coatings?<\/h2>\n\n\n\n

We use two oil coatings because our goal is to produce a higher-end touch surface rather than simply meet the basic touch requirement.<\/strong> The second coating gives us greater process flexibility and control over the final surface.<\/p>\n\n\n\n
