Information
Today we will talk about the classification and characteristics of the main forest material of food vacuum bags.
 
Several types of composite materials for vacuum bags are generally:
 
PA/PE or PA/RCPP    PET/PE or PET/RCPP
 
There are also three-layer and four-layer, 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.
 
Then according to the needs, combination, various properties, there are also transparent, in order to increase the barrier performance, use the water-resistant PVA high barrier coating.
 
Several common vacuum packaging 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, NY/AL/RCPP, NY/PE    Features: moisture resistance, temperature resistance, 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. For the film materials used in food vacuum packaging, it is necessary to ensure that the packaging effect, aesthetics, and economy of various foods are in the best state. At the same time, food vacuum packaging also has higher requirements for 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.
