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.

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

Polyethylene (PE) is a thermoplastic polymer with variable crystalline structure and an extremely large range of applications depending on the particular type. It is one of the most widely produced plastics in the world.

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
