Salmon Vacuum Bag
Co-extruded vacuum packaging bags typically consist of a multi-layer co-extruded film, with the inner and outer layers made of PE. A middle layer can contain high-barrier materials such as PA and EVOH. This structure effectively prevents the permeation of oxygen, water vapor, and odors, while also protecting the product from factors such as light and temperature.
Advantages of Co-extruded Vacuum Bags:
High Barrier
Leveraging the high-barrier properties of different plastic materials, the co-extruded film achieves a high barrier effect against oxygen, water, carbon dioxide, and odors.
Strong Stability
Oil-resistant, moisture-resistant, and freeze-resistant, it preserves quality, freshness, and odors, making it suitable for vacuum packaging, aseptic packaging, and inflatable packaging.
Low Cost
Co-extruded film is manufactured using co-extrusion technology in a single piece, resulting in a relatively simple production process and significant cost advantages.
High Safety
No adhesives are added, resulting in no residual solvent pollution, making it environmentally friendly.
