Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. Flexible, not crinkly. Ease of processing, Ease of sealing, barrier to moisture.
High-density polyethylene (HDPE)
High-density polyethylene or polyethylene high-density is a polyethylene thermoplastic made from petroleum. Semi rigid, Sinks in water, Resistance to moisture, permeability to gas
Polyethylene terephthalate, commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family. Usually clear or green, sinks in water, rigid. Barrier to gas and moisture.
Polypropylene (PP), Also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles, stationery, plastic parts and reusable containers
Polypropylene Homopolymer (PPH) is the most widely utilized. PPH offers a high strength to weight ratio, this combined with good chemical resistance and weldability allows this material to be used in many corrosion resistant structures.
Polystyrene (PS) is a synthetic aromatic polymer made from the monomer styrene. General-purpose polystyrene is clear, hard, and rather brittle. Semi rigid, low gloss, resistance to heat, chemicals, grease and oil, versatile barrier to moisture.
Polyvinyl chloride, also known as poly vinyl or vinyl, commonly abbreviated PVC, is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene. Semi rigid, glossy, Sinks in water
