HDPE Regrind

HDPE Regrind

HDPE:
It is an abbreviation for High Density Poly Ethylene.

Post Consumer Regrind (PCR):
PCR is post consumer plastic products that have been recycled, this means they are ground down to be re-used in manufacturing of new products made of the material in question. Level of grinding can be between 25-100%.

HDPE post consumer regrind is recycled High Density Poly Ethylene cut into small pieces. The HDPE regrind can be sorted by color or mixed. HDPE plastic regrind made by HDPE processors should be ideally loaded directly into a wash system and processed completely into a finished product.

If the HDPE regrind has to be stored, it should be ground directly into and stored in gaylords. Gaylords are extra heavy duty boxes that are mounted on pallets for shipping loose items. They have about one cubic yard in volume and are capable of holding HDPE flakes in the range of 600-1000 pounds. The gaylords should be fastened on shipping pallets to maintain their integrity during handling, storage, and transport.

HDPE regrind use:
Generally natural HDPE regrind is used in high value end-use applications (such as clear, blown film). It requires higher quality especially with regard to injection-molded HDPE, Polypropylene, and color contamination. The quality requirements for HDPE regrind are normally more demanding than for baled HDPE.
