In order to meet the requirements of the masses, according to the customer's response, according to repeated studies, it was found that according to the flexibility of modified material PP, the characteristics of the tonnage bag could be greatly improved. According to the blending test and modification of PP, nano-technology filler and anti-ultraviolet absorbent, the eye camera group greatly improved the high hardness of the tonnage bag in the natural environment of lower temperature and caused the breakage. The cracking condition reasonably improves the anti-ultraviolet and anti-wear properties of ton bags, fully guarantees the stipulation of packing and transporting PP ton bags at ultra-low temperature, and can be good for the convenience of commodity transportation.
