Ultra-High Barrier Transparent MDOPE 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) and high transparency. Additionally, it is microwaveable for sterilization and detectable by metal detectors.
Product Applications:
Widely used in:
- **Food Packaging**: Suitable for biscuits, snacks, pet food packaging.
- **Electronics Packaging**.
- **Liquid Packaging**.
- **Boiled and Microwaveable Packaging**.
Process Structure:
MDOPE / Coating / Aluminum Layer
Specifications:
- **Base Material Thickness**: 25–50 μm
- **Width and Dimensions**: Customizable based on customer requirements.
