Today, I would like to introduce some kinds of materials for plastic boxes, which are also commonly used in the plastic box industry. The first is "PP" material. It is safe, environment-friendly, non-toxic and light in weight. It is widely used in infant product packaging. The second is "PVC" material, which is harmful to human body without environmental protection. But PVC material is the most used by people. It has advantages of heat and moisture resistance, transparency and so on. Third kinds: "PET" material, it is also environmentally friendly material, can be used directly in the packaging of food, PET plastic box will generally be widely used in cylinder, folding box and other fine plastic boxes.
