Product characteristics

This product is self-developed by our company and has multiple patented technologies. The product adopts imported raw materials from abroad, with high barrier resin as the intermediate layer, and is produced through a multi-layer co extrusion blown film production line. This product has excellent barrier properties, good heat sealing properties, and mechanical properties such as puncture resistance. The barrier performance is better than that of the casing film by more than ten times, and can be widely used in products that require vacuum pumping and inert gas filling for protection.

performance
1. High barrier: It can achieve high barrier effects on oxygen, water, carbon dioxide, odor, and other substances.

2. Strong functionality: resistant to oil, moisture, high-temperature cooking at 120 degrees Celsius, resistant to low temperature freezing, quality preservation, freshness preservation, and odor preservation. It can be used for vacuum packaging, sterile packaging, and inflatable packaging.
3. Low cost: Compared to glass packaging, aluminum foil packaging, and other plastic packaging, co extruded film has a significant cost advantage in achieving the same barrier effect. Due to its simple process, the cost of the produced thin film products can be reduced by 10-20% compared to dry composite films and other composite films.

4. Flexible structural design: By adopting different structural designs, different quality assurance requirements can be achieved.

5. High strength: The co extruded film has the characteristic of stretching during the processing. The strength of the plastic can be correspondingly increased after stretching, and plastic materials such as nylon and metallocene polyethylene can be added in the middle to make it have composite strength that exceeds that of general plastic packaging. There is no delamination phenomenon, good flexibility, and excellent heat sealing performance.

6. Small capacity ratio: Vacuum shrink packaging can be used, which is incomparable to glass, iron cans, and paper packaging.
7. Good transparency, softness, and tight fit with the product
