There are many ways to choose food vacuum bags. We will briefly explain which is the most suitable choice from the material, composite type and material characteristics.
1. Material requirements for food vacuum bags
Because it needs to be vacuumized and some need to be cooked at high temperature, RCPP is the most suitable inner layer. Aluminum foil can be added to the middle layer, which can increase barrier properties, shading properties, and avoid accelerated deterioration of food. The surface layer can use the most commonly used PET.
2. Composite types of food vacuum bags
For two-layer materials, you can choose PA/PE or PA/RCPP, PET/PE or PET/RCPP, and for three-layer materials, you can choose PET/PA/PE, PET/AL/RCPP, PA/AL/RCPP, PET/ PA/AL/RCPP.
3. Material properties of vacuum bags
The material characteristics of food vacuum bags are moisture-proof, temperature-resistant, shading, fragrance-preserving, tough, and high-barrier: blocking oxygen, water, and carbon dioxide. No pollution: no binder is added, and there is no problem of residual solvent pollution.
Precautions for custom-made packaging bags: Determine the bag type, size, material, and thickness. If there are samples, it is best to mail them directly to the factory, so that the factory can quote directly according to the samples.
