Vacuum packaging material compound classification

by:Kolysen     2020-06-21
We said, most of the packaging products are composite bags, vacuum bags is no exception, the composite material is generally what kinds of combination of vacuum packing bag?

today we are here said the vacuum bags compound classification:

1, the PA/PE, nylon material with PE, flexibility and high sealing performance.

2, PA/RCPP material, these two kinds of material of vacuum bags for cooking level of transparent vacuum bags.

3, PET/PE material, use PET material rather than nylon, are generally given its cost is low.

4, PET/RCPP material, resistant to cooking class transparent vacuum bag, cost is low.

the above several are two composite vacuum bags, in the life of three composite, four composite used in vacuum packaging. So how are they compound?

1, PET/PA/PE material, transparent three composite vacuum bag, high flexibility, high cost.

2, PET/AL/RCPP is qualitative, opaque three compound bag, vacuum low flexibility, have qualitative feeling composite aluminum foil layer, the high cost.

3, PA/AL/RCPP is qualitative, not transparent vacuum bags, choose rather than PET film, nylon membrane increased the flexibility of the bag, not easy to damage, the cost of higher than 2 classes.

4, PET/PA/AL/RCPP material, four composite vacuum packaging on the market are not many, many have special requirements for the packing of the products. Belongs to the highest level of vacuum packaging.
