Structure and characteristics and application scope of seven layer coextrusion film
1) Seven-layer co-extrusion film---asymmetric low temperature, boiled film Basic structure is: PA/TIE/PE/TIE/PA/TIE/PE Widely used for vacuum moisture, fresh, oxidation products such as: food, fruits and vegetables. Agricultural and sideline products. Clothing. Petrochemical industry, machinery, instruments, military industry (weapons), etc. Available as pork, beef and mutton, chicken, duck, goose, fish, shrimp and various seafood products need to be frozen from-18 ℃ to-15 ℃. Can be used as a variety of cooked meat food such as ham, sausage, jam, peanuts, bean products such as dried bean curd, all kinds of fillings such as bean paste filling need to vacuum pasteurized to bacteria packaging.

2) seven-layer co-extrusion film- -high barrier. Impermeable packaging membrane Basic structure is PE/TIE/PA/EVOH/PA/TIE/PE Use in a variety of cooked meat food, coffee, tea, flavors, spices, food additives, cosmetics and other shelf period Luo long product packaging. Also used in petroleum, chemical, pesticide, highly toxic, acid, salt and other permeable and corrosive product packaging.

3) seven-layer co-extrusion film-- - inflatable, plastic wrap Basic structure is: PE/TIE/PA/TIE/PA/TIE/PE Air-keeping packaging for food and inflatable packaging areas such as balloons

4) seven-layer co-extrusion film----Fresh meat plastic wrap Basic structure is: PE/TIE/PA/EVOH/PA/TIE/EVA

It has excellent barrier performance and can be stored at low temperature below - 25 ℃.
1. High barrier: the barrier properties of different plastic materials are quite different. Coextrusion film can achieve high barrier effect on oxygen, water, carbon dioxide and odor.
2. Strong function: oil resistance, moisture resistance, high temperature cooking resistance of 120 ℃, low temperature freezing resistance, good quality, fresh-keeping, odor protection, can be used for vacuum packaging, aseptic packaging, inflatable packaging.
3. Low cost: compared with glass packaging, aluminum foil packaging and other plastic packaging, to achieve the same barrier effect, coextrusion film has a greater advantage in cost. Because of the simple process, the cost of the film product can be reduced by 10-20% compared with the dry composite film and other composite films.
4. Flexible structure design: different structure design can meet your different quality requirements.
5. High strength: the coextrusion film has the characteristics of stretching in the process of processing, and the strength of plastic can be improved correspondingly after stretching, or nylon, metallocene polyethylene and other plastic materials can be added in the middle to make it have the composite strength higher than that of general plastic packaging, without delamination phenomenon, good softness and excellent heat sealing performance.
6. Small capacity ratio: coextrusion film can be packed by vacuum shrinkage, and the capacity volume ratio is nearly the same 100% ， This is incomparable to glass, tin and paper packaging.
7. No pollution: no residual solvent pollution, green environmental protection.

At present, Zhuhai Xutai Commodity Co., Ltd., has introduced the seven-layer common extrusion film production lines imported from Italy, with complete supporting facilities, advanced production technology and strong technical force. The produced seven layers of total extrusion high-barrier (nylon film) soft packaging materials are widely used in: food (raw fresh meat, fish, dried beef, dried tofu, cooked food, etc.), medical, mechanical, electronic, chemical, textile (vacuum compression bag, storage bags, storage bags, bedding). Pesticides, emulsion products, modern agricultural packaging and other fields.
