What grade of PP material is required for PP food blister packaging?
The general characteristics of the natural PP material can only be resistant to low temperature, so the product can be refrigerated, generally used in supermarket meat, cooked food packaging, the color can be PP white, or PP other colors green, red can be.
PP color transparent material, we also call translucent PP material, the characteristics of this material have high temperature and low temperature resistance, but low temperature and high temperature resistance are not very good. Therefore, we can only do some products that are not very strict with low temperature and high temperature resistance. They are generally used for factory dumplings, dumplings, and dumplings. This product can not be placed in the high temperature processing of micro boilers.
PP high transparent material, this PP material is better for low temperature and high temperature resistance, and can also be sealed, and the price of this material is also high. Therefore, some products need high temperature resistance and low temperature resistance. We generally use high transparent PP materials to produce products. The products produced by this PP material are not problematic in high temperature processing.
PP material actually has a lower density, so the product is thinner than other materials such as PVC and PET after blister molding, so we need to use thicker materials than other materials when designing PP products.
Those products are suitable for packaging in blister packaging
