PP Shrink Wrap is a thermoplastic resin produced by polymerization of propylene, the density of 0.9g/cm3, is one of the lightest varieties of all plastics at present, with good strength, hardness and heat resistance, is a food-grade thermoplastic material. It is widely used in food packaging, such as lunch boxes, water cups, baby bottles, etc.
1, physical properties: non-toxic, odorless, tasteless, milky white high crystalline, low density, good stability to water.
2, thermal performance: Children's Toy Packing PP Shrink Wrap has good heat resistance, its products can be sterilized at temperatures above 100℃; Under the premise of no external force, the high temperature of 150 ° C will not be deformed.

3, chemical stability: Children's Toy Packing PP Shrink Wrap is good chemical stability, in addition to being eroded by concentrated sulfuric acid and concentrated nitric acid, it is not easy to react with other chemical reagents. At the same time, its chemical stability will increase with the increase of crystallinity, so polypropylene is suitable for making a variety of chemical pipes and accessories, with good anti-corrosion effect.
4, electrical performance: has a high dielectric coefficient, and the electrical performance will become better with the increase of temperature, so it can be used to make heating electrical insulation products.
