1. The Science Behind PET Sealing Film
PET (Polietilen terefallate) sealing films are engineered through a precision biaxial stretching process, yielding a material with outstanding optical clarity, low haze, and high tensile strength. A 2024 study in theJournal of Mechanical Science and Technology highlighted how optimizing sealing parameters—such as temperature gradients and pressure—enhances bond integrity in multilayer polypropylene films, a principle equally applicable to PET variants.
Modern PET sealing films often incorporate composite layers. Masalan; misol uchun, a 2024 patent disclosed a tri-layer structure comprising:
- Outer PET Layer: Provides mechanical rigidity and heat resistance.
- VMPET (Vacuum Metallized PET) Qatlam: Enhances barrier properties against oxygen and moisture.
- Inner PE (Polietilen) Blend Layer: Combines EVA, EAA, HDPE, and LLDPE to boost flexibility and adhesion.
This blend ensures the film maintains its seal at temperatures ranging from-80°C to 110°C, making it ideal for cryogenic storage and high-temperature sterilization.
