Quality standards of PP/LDPE/HDPE

For the test items and the methods and standards of the plastic bags of low-density polyethylene (LDPE). <low-density polyethylene resin> provides for its technical requirements, test methods, inspection rules, marking, packaging, transportation, storage. This standard applies to the ethylene monomer, the radical type initiator under high pressure polymerization system have low density polyethylene homopolymer content in less than 5% of 1 – olefin copolymers and polymer containing additives. Technical requirements: Low-density polyethylene resin was milky white cylindrical particles, the particle size is 2-5mm in any direction, does not allow the entrained metal mechanical impurities.
