| Structure | Advantages |
| PA／EVOH／PP or PE/PA/EVOH/PA/PP | ◆EVOH barrier, high resistance |
| EVOH barrier | ◆PA surface, good moisture resistance |
EVOH/PA/PP high barrier co-extrusion film -
1. High barrier: By using different plastic materials with different barrier properties and differences, co-extruded films can achieve high barrier effect for oxygen, water, carbon dioxide, smell, etc.;
2, Strong function:Oil resistant, resistant to moisture, resistant to high temperature of 120 ℃ cooking, resistant to low temperature freezing, with good quality, fresh and smell. It can be used in vacuum packaging, aseptic packaging and inflatable packaging.
3. Low cost: Compared with other plastic packaging, glass packaging and aluminum foil packaging, co-extrusion film has great advantages in cost to achieve the same blocking effect. Due to the simplicity of the process, the product cost can be reduced by 10-20% compared with the dry composite film and other composite films.
4. Flexible structural design: Different structural design can be adopted to meet the warranty requirements of different products;
5. High strength: The co-extrusion film has the characteristics of stretching during the processing. After plastic is stretched, the strength can be increased correspondingly.
6. Small capacity: The co-extrusion film can be vacuum-shrink packed, and the capacity volume ratio is almost 100%, which cannot be compared with glass, tin and paper packaging.
7. No pollution: No adhesive added, no residual solvent pollution, and green and environmental protection.
Product advantages:
1.Positive transparency
2.Excellent puncture resistance
3.Excellent water vapor and oxygen barrier
4.Excellent high and low temperature tensile molding performance
5.Safe and green packaging without any residual solvent
6.Mixer applies to - 30 ℃ low temperature cold storage, 121 ℃ high temperature steaming or boiling sterilization
Application:
1.Vacuum food packaging:Rice, meat products, dried fish, aquatic products, preserved meat, roast chicken, roast pig, frozen food, ham, cured meat products, sausage and cooked meat products, pickles, bean paste, seasoning, etc.
2. Industrial products: Anti-oxidation and anti-corrosion of welding materials, electronic products, circuit boards, precision machine accessories, etc.
