What type of raw material is used in plastic bags? The brightness is good. It blows out as bright as a mirror! That kind of transparency!
PE, the solute has high pressure and good transparency. I've seen a high transparent vegetable packing bag. That's a secret formula
LDPE high pressure 2424H, Lanzhou petrochemical, LLDPE, 7042N, Lanzhou petrochemical. Transparency can reach 90%. The temperature should be controlled during blowing.
High density polyethylene (LDPE) transparency, the equivalent number can reach about 90%, but the temperature should be controlled well, there is no general problem, that is, the cost is higher than other products
