Polypropylene, abbreviated as PP, is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene (PP) is a thermoplastic synthetic resin with excellent properties, which is a colorless and translucent thermoplastic lightweight general-purpose plastic.

PP plastic sheet is not harmful to the human body. The lunch box made of food-grade PP plastic sheet is non-toxic and harmless, and can be safely used for food. At the same time, the food-grade PP lunch box has good heat resistance, the melting point is between 164-170 degrees, and no toxic substances are produced under high temperature. Therefore, the food-grade PP lunch box can be boiled and sterilized in water, and it is not easy to deform after long-term use at a temperature of 100 degrees.

Food blister packaging boxes are basically made of PP plastic sheets. According to the customer's requirements for the product and the characteristics of the product itself, there are many types of PP plastic sheet choices. These include PP natural color, PP natural color transparent, PP high transparent plastic sheet and PP sheet in other colors. The characteristics of the products produced by each PP material are different, and the uses are also different.

Among the commonly used materials for the production of blister packaging boxes, PP plastic sheets play an important role. The PP sheet is thinner than other materials after molding, so it is thicker when the material is used, but this does not affect its transparency. So what are the uses of blister packaging boxes made of PP materials with different transparency?

Natural color PP plastic sheet
The general characteristics of natural PP material can only be resistant to low temperature and can be used for refrigeration. Generally, the packaging trays of fish and meat in supermarkets and cooked food are made of PP. The color can be PP natural white, or PP other colors.

Translucent PP plastic sheet
Products made of translucent PP material generally have good high temperature resistance and low temperature resistance, but the performance is not very good, so it can only be used in products that do not have high requirements for low temperature and high temperature resistance. Try to avoid direct high temperature heating. Generally used for the packaging of dumplings, xiaolongbao, dumplings, frozen pasta, etc.

PP high transparent plastic sheet
Products made of highly transparent PP material have better low temperature and high temperature resistance performance, and can also be sealed, but the price of this material is relatively high. It is suitable for products with high requirements for high temperature resistance, and it is no problem to directly use it for high temperature heating in microwave ovens.

Packaging boxes produced from PP materials with different transparency will have a big difference in the scope of application. When purchasing products, you should choose a suitable blister packaging box according to the needs of the packaged products. To produce different blister packaging, it is necessary to select different PP sheet raw materials according to the needs of use.
