Overview
HDPE blow molding grade features high density, modulus and rigidity, good environmental stress crack resistanse and excellent processability. The resin is suitable for making large and medium-sized containers holding liquids by blow-molding.
Applications
HDPE blow-molding grade can be used for producing smallsized containers such as milk bottles, juice bottles, cosmetics bottles, artificial butter cans, gear oil barrels and auto lubricant barrels. It can also be used in the production of intermediate bulk-containers(IBC), large toys, floating matters and large and medium-sized containers such as packaging-use barrels.
Package, Storage & Transportation
The resin is packaged in internally film-coated polypropylene woven bags, brown paper bags or laminated polyethylene film bags. The net weight is 25Kg/bag. The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
