PET Twist Film is a practical alternative to PVC Twist Film for candy and snack packaging because it combines good twist retention, high strength, excellent clarity, and stable processing. It can hold a tight twist without strong rebound. PET also allows thinner film structures while maintaining the stiffness needed for twisting and wrapping. For manufacturers looking for a reliable PVC alternative, PET Twist Film offers a strong balance between packaging performance and material efficiency.
PET Twist Film Offers Better Material Advantages
PET is a widely used packaging material with good clarity, strength, and recyclability. It is commonly used in beverage containers, food packaging, and flexible film applications.
Compared with traditional PVC Twist Film, PET does not rely on the same PVC-based material system. This makes PET an attractive option for brands and converters looking for alternative packaging materials.
PET also has good optical properties. Its high transparency and gloss help candy packaging maintain a clean and attractive appearance.

Why Is Twist Performance Important?
Good twist retention is one of the most important requirements for candy wrapping film. After the film is twisted around the candy, it should stay in position instead of quickly opening or returning to its original shape.
PET Twist Film can provide strong twist performance and good twist retention when the film structure and processing are properly designed. This makes it suitable for applications where the twisted ends are part of the package appearance.
For confectionery manufacturers, stable twisting can also support consistent packaging quality during high-speed production.
PET Twist Film Can Be Made Thinner
PET Twist Film can achieve the required strength and stiffness at a lower thickness than many traditional PVC Twist Film structures. Depending on the application, PET Twist Film can be produced at thicknesses such as 19 μm and 23 μm.
A thinner film can reduce material consumption per package. It can also help converters improve material utilization while maintaining the mechanical properties needed for twisting.
The actual film thickness should be selected according to the candy size, wrapping equipment, twist requirements, printing process, and end-use conditions.
PET Provides Stable Film Quality
Biaxial orientation gives PET film good mechanical strength and dimensional stability. This production process helps create a film with more uniform thickness and consistent physical properties.
Stable film quality is important for packaging converters. Variations in thickness or mechanical properties can affect printing, metallization, cutting, and wrapping performance.
High-quality PET Twist Film can therefore support more consistent downstream processing and help reduce production variation.

PET Twist Film Is Suitable for Printing and Metallization
The stable structure and mechanical strength of PET make it suitable for further converting processes such as printing and aluminum metallization. This is important when candy packaging needs decorative graphics, metallic effects, or improved visual appeal.
For packaging converters, consistent film thickness can also help improve process control during printing and metallization.
This makes PET Twist Film more than a simple wrapping material. It can be part of a complete packaging structure designed for both appearance and production efficiency.
PET Twist Film vs. PVC Twist Film
The main differences between PET and PVC Twist Film are related to material properties, thickness, mechanical strength, and processing requirements.
| Feature | PET Twist Film | PVC Twist Film |
|---|---|---|
| Transparency | High | High |
| Gloss | High | High |
| Twist retention | Good | Good |
| Mechanical strength | High | Moderate to high |
| Typical thin-film option | 19–23 μm possible | Often requires greater thickness |
| Thickness uniformity | Good with biaxial orientation | Depends on production process |
| Printing | Suitable | Suitable |
| Metallization | Suitable | Application dependent |
| Material efficiency | Potentially higher | Generally lower at equivalent stiffness |
The right choice still depends on the packaging machine, product requirements, and final film structure. PET should be evaluated through actual twisting, wrapping, printing, and converting tests before large-scale production.

FAQ About PET Twist Film
1. What is PET Twist Film?
PET Twist Film is a PET-based packaging film designed to wrap products using a twisting process. It is commonly considered for candy, confectionery, and small snack packaging where twist retention is important.
2. What thickness is available for PET Twist Film?
PET Twist Film can be designed in thin structures such as 19 μm and 23 μm, depending on the application. The best thickness depends on the product, machine, wrapping speed, and required stiffness.
3. Can PET Twist Film be used on existing candy wrapping machines?
It may be compatible with existing equipment, but machine testing is recommended before mass production. Film tension, friction, stiffness, sealing or wrapping conditions, and twisting parameters can affect machine performance.
4. Can PET Twist Film be printed?
Yes, PET film can be used for various printing processes. The suitable surface treatment and ink system should be selected according to the printing method and final packaging requirements.
5. Can PET Twist Film be metallized?
Yes, PET film can be used as a substrate for aluminum metallization. Metallization can provide a metallic appearance and additional barrier performance depending on the final packaging structure.
6. What factors affect PET Twist Film’s twist retention?
Film thickness, orientation, stiffness, surface characteristics, processing conditions, and twisting parameters can all affect twist retention. The film should therefore be evaluated together with the customer’s wrapping equipment and product.
7. Can Shandong Shunzhan New Materials customize PET Twist Film?
Yes, film specifications can be discussed according to the customer’s application. Customers can provide requirements such as thickness, width, packaging product, wrapping method, and expected production speed for technical evaluation.
