Excellent Twist Retention: PET twist film can withstand significant twisting, maintaining a twist angle of up to 270° with a rebound of less than 30°, firmly preserving the knotted shape. This provides reliable support for twist packaging of candies, chocolates, and other products, ensuring the packaging remains tight and aesthetically pleasing during transportation and sales.
-
High Mechanical Strength: Exhibiting outstanding tensile strength, the film reaches 210-260MPa in the machine direction (MD) and approximately 283MPa in the transverse direction (TD), with a high elastic modulus (3800MPa in both MD and TD). This prevents the film from tearing during packaging, offering excellent product protection and enabling easy handling of heavy or irregularly shaped items.
-
Good Chemical Stability: The film shows strong resistance to common chemicals like oils, fats, acids, and alkalis, without performance degradation or corrosion from contact. This makes it ideal for packaging oily foods such as nuts and meat products, effectively preventing content spoilage and extending shelf life.
-
Food-Grade Safety Standard: Non-toxic and harmless, it meets strict food-contact safety standards. For example, domestically produced PET twist film has passed FDA testing, allowing direct contact with food to ensure safety and consumer confidence in packaged products.
-
High Transparency and Gloss: With high transparency (haze as low as ~3%), it clearly displays product appearance, enabling consumers to view contents directly. Its gloss of up to ~120% enhances packaging aesthetics, boosting product appeal and grade—particularly suitable for high-end candies and gifts.
-
Antistatic Performance: Surface treatment effectively prevents static electricity, avoiding dust adsorption or film sticking during packaging. This ensures smooth packaging operations and improves efficiency and quality.
