Introduction of Food Vacuum Sealing Bag Material Types

Today we will talk about the classification and characteristics of the main materials of food vacuum sealer bags.

Several types of composite materials for vacuum bags are generally

PA/PE or PA/RCPP PET/PE or PET/RCPP also has three or four layers,

In order to increase the material texture performance PET/PA/PE PET/AL/RCPP PA/AL/RCPP PET/PA/ AL/RCPP

The classification of materials for vacuum packaging, the following are the characteristics of each material suitable for vacuum packaging

1. PE is suitable for low temperature use, RCPP is suitable for high temperature cooking;
2. PA is to increase physical strength and puncture resistance
3. AL aluminum foil is to increase the barrier performance and shading
4. PET increases mechanical strength and has excellent stiffness.
    

Several common food vacuum sealer bags

High-temperature retort bags and vacuum bags are used for packaging various cooked meats, which are easy to use and hygienic.

Material: NY/PE, NYAL/RCPP, NY/PE Features: moisture-proof, temperature-resistant, shading, fragrance retention, toughness

Application: high temperature sterilization food, ham, curry, roast eel, roast fish and meat stewed products.

At present, the most used vacuum packaging is mainly film materials, of course, bottles and cans are also used. The film materials used in food vacuum sealer bags must ensure the best packaging effect, aesthetics, and economy for various foods. At the same time, food vacuum sealer bags also have higher requirements on the light barrier and stability of the material. When a single material cannot meet these requirements, the packaging will often be composed of a variety of different materials.
