High-Barrier BOPP Aluminum Oxide-Coated Film
Product Introduction:
Using vacuum coating technology, this film is produced by depositing a layer of aluminum oxide onto the surface of BOPP film, providing extremely high barrier performance. It effectively prevents the penetration of oxygen, water vapor, aroma, and other gases and substances.
Product Applications:
Widely used in the packaging of oxygen- and moisture-sensitive products such as food, pharmaceuticals, spices, and electronic components. It is also applicable in cosmetics, daily necessities, and other fields.
Specifications:
- Thickness: 20 μm, customizable based on customer requirements.
