PP plastic box is a kind of packing box made of PP material, with smooth PP plastic box, frosted PP plastic box, transparent PP plastic box, white PP plastic box.
PP plastic box has the following characteristics:
1, the effect is good, plastic varieties, easy to color, bright color, according to the need to make different types of packaging containers, to obtain the best packaging effect.
2, easy to mold, as long as the replacement of the mold, you can get different varieties of containers, and easy to form mass production.
3, have better corrosion resistance, acid and alkali resistance, oil resistance, impact resistance, and have good mechanical strength.
4, can be used transparently, you can not open the package, you can see the product style inside the package.
5, can design a variety of color patterns, design different shapes, in order to improve product quality, improve product competitiveness.
6. Allow consumers to see your products and promote your products more easily;

What are the characteristics of PP?
1. Crystalline material, low moisture absorption, prone to melt fracture, long-term contact with hot metal easily decomposed.
2. The fluidity is good, but the shrinkage range and the shrinkage value are large, and the shrinkage holes, dents and deformations are easy to occur.
3. Cooling speed, pouring system and cooling system should be slowly cooling, and pay attention to control the molding temperature. Material temperature easy to orientate at low temperature and high pressure, the mold temperature is lower than 50 degrees, the plastic parts are not smooth, easy to produce poor welding, flow marks, More than 90 degrees warp deformation
4. The plastic wall thickness must be uniform to avoid lack of glue and sharp corners to prevent stress concentration.
