1. Seven layer co extruded film - asymmetric low-temperature and water boiled film
The basic structure is: PA/TEE/PE/TIE/PA/TEE/PE
Widely used for vacuum moisture-proof, fresh-keeping, and oxidation resistant products such as grains, fruits and vegetables, agricultural and sideline products, clothing, petrochemicals, machinery, instruments, military (weapons), etc. It can be used as a fresh-keeping packaging for pork, beef and mutton, chicken, duck, goose, fish, shrimp, and various seafood products that require freezing at -18 ℃ to -15 ℃. It can be used as packaging for various cooked meat products such as ham, sausages, jam, peanuts, soy products such as dried tofu, tofu shreds, and various fillings such as bean paste that require vacuum pasteurization.
2. Seven layer co extruded film - high barrier, anti-seepage packaging film
The basic structure is: PE/TIE/PA/EVOH/PA/TIE/PE
It is used for packaging products with long shelf life, such as various cooked meat products, coffee, tea, essence, spices, food additives, cosmetics, etc. It can also be used for packaging products with strong permeability and corrosiveness, such as petroleum, chemical, pesticide, highly toxic, acid, alkali, salt, etc.
3. Seven layer co extruded film - inflatable and fresh-keeping packaging film
The basic structure is: PE/TEE/PA/TIE/PA/TEE/PE
Used in the field of modified atmosphere packaging for food and inflatable packaging such as balloon wrap.
4. Seven layer co extruded film - fresh meat preservation film
The basic structure is: PE/TIE/PA/EVOH/PA/TIE/EVA
For fresh meat refrigeration and preservation of pigs, cattle, and lamb, it is required to immerse in water at 80 ℃ for 1-3 seconds and adhere to the body (or in a hot drying oven when exposed to heat). The product packaging has excellent barrier properties and can be stored at low temperatures below -25 ℃.
The advantage of this device lies in:; 1. Adopting a stacked mold structure to solve the decomposition problem caused by large temperature differences in raw materials,
4. A dedicated rotary winding machine solves the problem of wrinkling and stretching deformation of thin plastic film.
5. The combination of air ring and water ring solves the drawbacks of slow cooling and low output
6. Adopting 7-layer co extrusion. Solve the difficulty of single material formula and special process. Adapt to the processing of mixed materials.
7. Dedicated infrared radiation heating oven to solve the problem of water streaks on the surface of thin films
8. The water ring is equipped with a lifting mechanism, which can be freely and flexibly adjusted according to the width of the membrane bubble.
9. The downward inflation method was used to solve the problems of material flow fluidity and composite faults in PA and EOVH
