What are the materials of food vacuum packaging bags?
The performance of food vacuum packaging materials directly affects the storage life and taste changes of food. In vacuum packaging, choosing good packaging materials is the key to the success of packaging. What are the materials of food vacuum packaging bags?
1. Nylon composite food vacuum packaging bag
Material structure: pa/pe; PA/RCPP；
Nylon composite vacuum packaging bag is a vacuum packaging bag with high utilization rate in the market. It has good heat sealing performance, softness, high barrier performance, strong mechanical performance, puncture resistance and tear resistance.
2. PE composite food vacuum packaging bag
Material structure: pet/pa/pe; PET/PE； NY/PE
PE composite food vacuum packaging bag has strong air barrier performance, anti oxidation, waterproof and moisture-proof. Transparency, cheaper price, for those customers who do not have high requirements for vacuum? PE bags can be used for vacuum pumping, but the damage rate and air leakage rate are also relatively high.
3. Aluminum foil food vacuum packaging bag
Material structure: pet/al/pe; PET/NY/AL/PE； PET/NY/AL/CPP； PET/AL/PET/PE
Aluminum foil food vacuum packaging bag is a bag made of a variety of plastic films after compounding. It has good water and oxygen separation functions, strong mechanical properties, high explosion resistance, puncture and tear resistance. Storage environment temperature ≤ 38 ℃, humidity ≤ 90%; Product specifications: the conventional thickness is 0.10mm and 0.14mm, and the three side sealing and edge sealing are 10mm. Products of different composite materials and thicknesses can be customized according to customer requirements.
