            Whether the virgin PP strap is harmful to the human body must first be judged from the raw materials. Virgin PP strap is made of pure PP material, PP material (polypropylene) is a kind of plastic, it is a kind of linear polymer with high density, no side chain, high crystallinity, and has excellent comprehensive performance. Polypropylene is a non-toxic, tasteless, and odorless milky white highly crystalline polymer. It is currently one of the lightest varieties of all plastics.

Virgin PP Strap

          PP plastic has a specific gravity of 0.9-0.91 g/cm3, molding shrinkage rate of 1.0-2.5%, molding temperature: 160-220℃. PP is a crystalline polymer, and the overall performance of PP is better than that of PE. PP products have light weight, good toughness and good chemical resistance. Disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, it has post-shrinkage phenomenon, after demolding, it is easy to age, become brittle, and easy to deform. In daily life, the commonly used fresh-keeping box is made of PP material. It is particularly stable to water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000. The moldability is good, but because of the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent. For some parts with high dimensional accuracy, it is difficult to meet the requirements, and the surface of the products has good gloss.

           In addition to the application of PP materials on packing belts, they are also very common in our daily life, such as: plastic basins, barrels, furniture, films, woven bags, bottle caps, car bumpers, and so on. Generally speaking, PP plastic is not harmful to the human body. Its melting temperature is 220~275℃, and be careful not to exceed 275℃.

PP is a widely used plastic material. It has the characteristics of low density, good chemical resistance, low price, and excellent comprehensive performance. After modification, it can also be widely used in the field of home appliances. Generally, it is not harmful to the human body, so the virgin PP strap made of pure PP material will generally not cause harm to the human body.
