What are the key points for customizing vacuum food packaging?

In our daily life, vacuum food packaging is very common. Vacuum packaging bags have strong moisture resistance, high temperature resistance, high barrier properties, and toughness, and require no pollution or residual solvent contamination. So what are the differences in materials and precautions between vacuum packaging and other packaging?
1. Material requirements for vacuum packaging bags
Due to the special usage scenarios, vacuum packaging bags require high physical toughness and thermal stability of materials. Therefore, ordinary bags cannot be vacuum packaged. Materials commonly used to make vacuum packaging bags include PET, PE, PA, RCPP, AL, etc. Vacuum packaging can usually use RCPP as the inner layer, AL aluminum foil as the middle layer, and commonly used PET as the surface layer. Finally, it achieves the effect of blocking, shading, and slowing down the rate of food spoilage.
2. Composite type
The above introduces the requirements for the effectiveness of vacuum packaging and provides corresponding material suggestions. In fact, there are many material combinations for vacuum packaging bags, generally divided into two-layer and three-layer materials. For two-layer materials, PA+RCPP, PET+PE, PET+RCPP, or PA+PE can be selected; Three layer materials can be selected: PET+AL+RCPP, PET+PA+AL+RCPP, PA/AL/RCPP, PET/PA/PE. We can choose the material combination we want based on our own needs.
3. Precautions
In the process of customizing video vacuum bags, we need to determine the bag type, thickness, size, and material. It is best to provide samples to the factory and directly quote for production.
It should be noted that in the process of customizing vacuum bags, the specifications and dimensions of the product must be very precise and cannot be estimated roughly. Irregular bag shape, thin thickness, and uneven sealing can all cause air leakage in vacuum bags during use. Only by strictly adhering to specifications and dimensions can we ensure the customization of vacuum packaging bags that meet usage standards.
The above are the key points for customizing vacuum packaging bags. Vacuum packaging is different from ordinary packaging, and we need to pay special attention to size and material issues when customizing to ensure a better user experience in the future.
