Today we are going to talk about the classification and characteristics of the main forest materials of the food vacuum bag.
Several kinds of composite materials of vacuum bag are generally as follows:
PA/PE or PA/RCPP PET/PE or PET/RCPP
There are also three or four layers in order to increase the material properties:
PET/PA/PE PET/AL/RCPP PA/AL/RCPP PET/PA/ AL/RCPP
The classification of materials and materials for vacuum packaging is as follows:
1.PE is suitable for low temperature use and RCPP is suitable for high temperature cooking.
2. PA is for increasing physical strength and puncture resistance;
3. AL aluminum foil is designed to increase barrier performance and shade;
4. PET, increase mechanical strength, excellent stiffness.
And then depending on the requirements, the combination, the various properties, also have transparent, in order to increase the barrier performance using the water-resistant PVA high barrier coating.
Several common vacuum packaging bags
High temperature cooking bag and vacuum bag are used to package all kinds of meat cooked food.
Material: NY/PE, NY/AL/RCPP, NY/PE features: moisture-proof, temperature-resistant, light-blocking, aromatic protection, strong and tough
Application: high temperature sterilization food, ham, curry, roast eel, roast fish and meat marinade.
At present, the most commonly used vacuum packaging materials are thin film materials, of course, also used in bottles and cans.The film materials used in the vacuum packaging of food should be guaranteed to achieve the best condition in terms of the packaging effect, aesthetics and economy of various foods.At the same time, the vacuum packaging of food material to resist light and stability of higher requirements.When a single material cannot meet these requirements, the packaging will often be composed of many different materials.
