Seven-layer co-extruded stretch film in food grade
Low temperature stretch film: Basic structure: PA/TIE/PE/TIE/PA/TIE/PE, Common specifications: 422, 522, 322MM (lower film) (upper film: 393, 493, 293MM)
High temperature stretch film: Basic structure: PA/TIE/PP/TIE/PA/TIE/PP Common Specifications: 422, 522, 322 MM (lower film) (upper film: 393, 493, 293MM)
It can be used in fresh-keeping packaging of pork, beef, mutton, chicken, duck, goose, fish, shrimp, and a variety of seafood (-18℃ ~ -45℃).

Features
1. Barrier: The co-extruded film makes use of different barrier properties of different plastic materials, being a barrier to oxygen, water, carbon dioxide, odor, etc.
2. Powerful function: It can resist oil, moisture, 120 ℃ high temperature cooking, low temperature freezing, and can preserve quality, fresh and odor. It can be used for vacuum packaging, aseptic packaging, and inflatable packaging.
3. Low cost: Compared to other plastic, glass and aluminum foil, the co-extruded stretch film has great advantages in terms of cost under the same effect of barrier. Due to the simple process, the production cost can be reduced by 10-20% compared with dry laminating film and other composite films.
4. Flexible structural design: It can use different structural designs, so as to meet the preservation requirements of different products.
5. High strength: The plastic enjoys improved strength after stretching. Nylon, metallocene, polyethylene plastic material can also be added in the middle to make it enjoy higher composite strength than ordinary plastic package. It has no delamination, good softness, and excellent heat sealability.
6. Small capacity volume ratio: The co-extruded film can adopt vacuum shrink packaging. The capacity volume ratio is almost 100%, which is unmatched by glass, iron can, and paper package.
7. Environmental protection: Added with no binder, it has no pollution problems due to residual solvent, so that it is green.
