The Benefits and Applications of PVDC Coated PET Film

In the world of packaging and material science, PVDC coated PET film stands out as a high-performance material offering exceptional barrier properties and versatility. This composite film is a blend of polyester (PET) and polyvinylidene chloride (PVDC), combining the strengths of both materials to deliver superior performance in various applications. In this blog, we’ll delve into what makes PVDC coated PET film unique, its benefits, and its diverse uses in different industries.

What is PVDC Coated PET Film?

PVDC coated PET film is a type of plastic film that features a coating of polyvinylidene chloride (PVDC) applied to a base layer of polyester (PET). The PET base layer provides strength and flexibility, while the PVDC coating imparts excellent barrier properties against moisture, gases, and odors. This combination results in a film that excels in protective packaging and other demanding applications.

Key Features of PVDC Coated PET Film

1. Exceptional Barrier Properties: The PVDC coating offers outstanding resistance to moisture, oxygen, and other gases. This makes PVDC coated PET film ideal for applications where preservation and protection from environmental factors are crucial.

2. High Strength and Durability: The PET layer provides excellent mechanical strength and durability. The film is resistant to tearing, puncturing, and abrasion, ensuring reliable performance in various conditions.

3. Clarity and Transparency: PVDC coated PET film maintains high clarity and transparency, allowing for clear visibility of packaged products. This is particularly valuable in applications where presentation is important.

4. Thermal Stability: The film exhibits good thermal stability, which means it can withstand temperature fluctuations without losing its performance characteristics. This makes it suitable for applications involving heat sealing and processing.

5. Flexibility and Conformability: PVDC coated PET film is flexible and can conform to various shapes and sizes. This adaptability is beneficial for packaging irregularly shaped items and ensuring a snug fit.

6. Recyclability: PET is a recyclable material, and while PVDC coatings can complicate recycling, efforts are being made to develop more sustainable solutions. The recyclability of the PET base layer contributes to the film’s overall environmental profile.
