HDPE- high-density polyethylene resin is a polyethylene thermoplastic made from petroleum. With a high strength-to-density ratio and is used in the production of plastic bottles, caps and closures, shopping bags, tubes, pipes, household products, etc. Resin identification code is #2
LDPE – low-density polyethylene resin is a thermoplastic made from the monomer ethylene. LDPE is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic bags and films. Resin identification code is #4
LLDPE - linear low-density polyethylene is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins. Its most common use is in plastic bags and sheets (where it allows using lower thickness than comparable LDPE), plastic wrap, stretch wrap, toys, covers, lids, pipes, buckets and containers, covering of cables, geomembranes, and mainly flexible tubing.
