Pp Plastic Material Corrugated Moving Box With Lid for fish, oysters, seafood wholesale

Odorless and non-toxic. Due to its regular structure and high crystallization, the melting point can be as high as 167 °C. Heat resistance and corrosion resistance, and the products can be sterilized by steam are its outstanding advantages. With low density, it is the lightest general-purpose plastic. The disadvantage is that it has poor low temperature impact resistance and is easy to age, but it can be overcome by modification. The copolymer-type PP material has lower heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but has stronger impact strength. 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 good surface stiffness and scratch resistance properties. PP does not have environmental stress cracking problems.
