High-Barrier Transparent MDOPE Film
Product Introduction:
This film features a specialized base layer created with water-based coating solutions to enhance water barrier performance. The external aluminum layer improves oxygen barrier properties, achieving dual barrier performance below 0.5. It offers a metallic gloss effect, exceptional moisture and oxygen barrier performance to extend shelf life, and excellent light shielding to prevent UV damage to packaged contents.
Product Applications:
Widely used in the packaging of tea, coffee, chocolate, spices, pharmaceuticals, as well as electronics, labels, cosmetics, and metal products.
Process Structure:
MDOPE / Coating / Aluminum Layer
