A U.S. company recently introduced a multi-layer film containing a moisture-proof layer. The material is transparent, strong, moisture-resistant, and stable, and can be widely used in the packaging of food, food, and pharmaceutical products. According to reports, this new product has better moisture resistance and transparency than PVDC (Polyvinylidene Chloride) as a barrier multilayer multilayer co-extruded film. Because the material does not use halogen-containing additives and plasticizers, its safety and environmental advantages are obvious. In addition, the product is made by pressing multiple layers at the same time in the manufacturing process. Compared with laminated films, there is less chance of contamination during production, and the processing process is also easy to grasp.
