High-Barrier PET Aluminum Oxide-Coated Film
Product Introduction:
This film features high aluminum layer adhesion and excellent composite performance, making it suitable for use as an intermediate layer in boiling applications. It offers high barrier properties (moisture, oxygen, and aroma retention), high transparency with a light transmittance of ≥87%, and is microwaveable for sterilization. Additionally, it can be detected by metal detectors.
Product Applications:
- **Food Packaging**: Suitable for biscuits, snacks, pet food packaging.
- **Electronics Packaging**.
- **Liquid Packaging**.
- **Boiled and Microwaveable Packaging**.
