High-Barrier BOPP Aluminum-Coated Film
Product Introduction:
This film features excellent aluminum layer adhesion, significantly enhancing the composite strength with other materials. It is designed for use as the middle layer in three-layer structures, promoting material homogeneity. The film offers superior oxygen and moisture barrier properties, effectively extending shelf life.
Product Applications:
With a metallic luster effect, it prevents exposure to visible light and ultraviolet rays, extending the shelf life of packaged products. The film also offers better processing performance and environmentally friendly recyclability. It is widely used in the packaging of dried fruits, tea, dehydrated food, pharmaceuticals, and more.
