PP Bottle (polypropylene) and PET (polyester) bottle contrast From the appearance, the transparency of the polyester bottle is higher than that of the polypropylene bottle. The polyethylene bottle has better hardness and high temperature resistance, but the temperature is brittle, while the polyester bottle is relatively It is soft, the transparency is close to the glass, and when the temperature is high, the bottle is easily deformed. PP bottles are mainly made of PP polypropylene, of which PP is usually a translucent colorless solid, odorless and non-toxic. The melting point can be as high as 167 ° C due to the high degree of crystallisation due to structural regularity. Heat-resistant, corrosion-resistant, steam-sterilizable products are its outstanding advantages. The low density is the lightest general purpose plastic. The copolymer type PP material has a low heat distortion temperature (100 ° C), low transparency, low gloss, low rigidity, but has stronger impact strength, and the impact strength of PP increases with the increase of ethylene content. . The Vicat softening temperature of PP is 150 °C. Due to the high degree of crystallinity, this material has excellent surface stiffness and scratch resistance. There is no environmental stress cracking problem in PP. A PET bottle is a plastic material called polyethylene terephthalate (PET) or PET, which is a combination of Terephthalic acid and Ethylene glycol. The resulting polymer. PET plastic has the characteristics of light weight, high transparency, impact resistance and non-fragmentation, etc. It can also prevent carbon dioxide gas, keep the soda water gas, light weight and good preservation. PP Bottle are more flexible than the PET bottle sterilization method and production environment requirements. https://www.ruichangpacking.com
