BR-PET Aluminum-Deposited Barrier Film
An aluminum-deposited PET film that effectively blocks oxygen, water vapor and light.
Packaging
BR-PET is created by depositing aluminum on a PET film using a special proprietary method.
- Effective aluminum adhesion, blocks water vapor, oxygen and light.
- No anchor coat, so film is highly heat resistant and stable.
- Choose performance types suited to your application from the wide range available, including high barrier and MD straight cut.
Features
- Blocks oxygen and water vapor
- Blocks light
- Stable heat resistance
- Suitable for DL (dry lamination)
- Various performance types (high adhesion, high barrier, MD straight cut, etc.)
