How to Understand PET Twist Film

PET twist film is a high-strength, high-clarity packaging film that is widely used in the packaging industry due to its unique characteristics. It is typically made from polyethylene terephthalate (PET) resin, which offers excellent physical properties and chemical stability.

Let’s first take a look at the features of PET twist film. PET twist film is named for its outstanding twistability. It has exceptional tensile strength and tear resistance, allowing it to twist easily and form a secure knot, making the packaging more firm and reliable. Due to the high strength of PET resin, PET twist film is less likely to tear when stretched, making it suitable for products that require strong packaging.

Secondly, PET twist film offers excellent clarity. Its high transparency makes the product inside the packaging easily visible, attracting the attention of consumers and enhancing the product’s visual appeal. The transparency also helps consumers better understand the quality and features of the product, building trust.

Additionally, PET twist film has excellent puncture resistance. Puncture resistance refers to the ability of the film to withstand external forces without being pierced. The high puncture resistance of PET twist film protects the product inside the packaging from external influences, extending the product's shelf life and quality.

PET twist film also has certain heat resistance and chemical resistance. It maintains stability at higher temperatures, making it suitable for packaging hot food and beverages. Moreover, PET twist film is relatively stable against most solvents and chemicals, protecting the product inside from chemical damage.

In packaging applications, PET twist film comes in various forms, such as single-layer film, multi-layer film, and biaxially oriented film. Depending on the specific packaging needs, different types of PET twist film can be selected to meet the product's requirements.

In conclusion, PET twist film offers many advantages to the packaging industry with its excellent twistability, transparency, puncture resistance, heat resistance, and chemical resistance. It is widely used for packaging food, beverages, cosmetics, and daily necessities, providing effective solutions for product preservation, protection, and promotion. As the packaging industry continues to evolve, PET twist film will continue to play an important role in the field, providing consumers with high-quality products and a better user experience.
