Different materials play a role in the food packaging is also different

food packaging is composed of a plastic flexible packaging materials structure, can be divided into single layer/composite/multi-layer composite simple categories, because of need packaging of food production process is different, so after compound and into the packing bag of the effect also is different. Vacuum, boiled, steamed, nitrogen gas packing, in the market, the supermarket is to belong to high-end class food packaging products, at the same time of production is also more complex, the common compound or multi-layer common compound is very popular in our daily life is used to direct contact with food packaging categories, applicable to the product shelf life is longer than the kind of food, such as in food, flour, all kinds of small food, etc.

in the production of food packaging mainly adopts material has: EVOH, PA, PET, PP, PE, a co-extrusion, does not contain harmful material such as benzene, ester, it of oxygen, water and carbon dioxide has high separation effect, can significantly extend the shelf life of products, packaging by vacuum contraction, capacity volume almost *, this is unmatched by glass, cans, paper, greatly reduces the production cost of you, it is widely used in vacuum moistureproof, preservation, anti oxidation products such as: food, fruits and vegetables, agricultural and sideline products, etc.

this simple prior to summarize some of the material is vacuum food packaging bags, as follows:

1. High-temperature cooking and frozen type packaging film

basic structure is: the PA/TIE/PP/TIE/PA/TIE/PP

for zongzi products can withstand 120 ℃ high temperature cooking, ability - again 25 ℃ low temperature freezing product packaging.

2。 Nylon type asymmetric boiled packaging film

basic structure is: the PA/TIE/PE/TIE/PA/TIE/PE

for jam, stuffing and need pasteurization products vacuum packaging.

3。 Nylon type asymmetric high barrier packaging film

basic structure is: the PA/TIE/PE/TIE/PA/EVOH/PA/TIE/PE

for moon cakes, pastries, bread twist product fill nitrogen Gao Baoxian type product of vacuum packaging, choose the packing can extend the shelf life of food.

4。 Nylon type asymmetric antibacterial packaging film

basic structure is: the PA/TIE/PE/TIE/PA/TIE/PE

for moon cakes, pastries, bread products such as packaging, the packaging the add & other; Nano & throughout; Antibacterial material, can effectively restrain and kill the vast majority of bacteria, can extend the shelf life of food.

manufacturer in choosing a food packaging must look at the first packaging manufacturer of all kinds of qualification, not to choose three products without enterprise, avoid food * problem, careful choice!
