The corrugated plastic shipping boxes are important transportation tools for auto parts, electronic products, hardware parts, fruits, vegetables, and seafood. The corrugated plastic box is made of lightweight and durable corrugated plastic sheets, and its main material is non-toxic and environmentally friendly polypropylene. It is loved by all walks of life because of its rich advantages and comprehensive functions. Then when buying corrugated polypropylene boxes, you need to pay attention to the following three points.
Look at the material of the board and not just look at its surface. Carefully look at the gloss of the surface of the sheet and the color of the cross-section. The corrugated pp sheets of pp shipping boxes are made of new materials. The black hollow board material will have a smooth and shiny surface; the colored and transparent boards will have uniform gloss, no pitting, spots, and even appear transparent shape or translucent shape, the appearance is better.
The hardness of the general sheet is also relatively poor, and the edge will be dented by lightly pinching it by hand, and some even cannot be returned after being dented. The good corrugated plastic sheet is stronger and tougher, and it is not easy to be torn.
The density of the board refers to the weight per square of the board. Under normal circumstances, the thicker the plate, the higher the weight, the higher the toughness, and the higher the price. However, the pp corrugated sheet box made of a certain thickness of plate can be suitable for your own use, because the thick plate will be harder. For those products with special requirements, the corrugated plastic shipping boxes with appropriate hardness are still used.
