Polyvinyl chloride colloquial: polyvinyl, vinyl; abbreviated: PVC) is the world's third-most widely produced synthetic plastic polymer (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year.
Low density polyethylene (LDPE) is used mainly in film applications for both packaging and non-packaging applications. Other markets include extrusion coatings, sheathing in cables and injection moulding applications. LDPE is the oldest and most mature of the polyethylenes (PE).
High-density polyethylene (HDPE) is a thermoplastic polymer produced from the monomer ethylene. It is popularly known for its massive strength-to-density ratio. Its molecular branch gives it strong tensile strength and intermolecular force. It is also harder, more opaque and can withstand extremely high temperatures. In addition, HDPE is a high molecular weight polymer, designed for an optimum balance of density, molecular weight, and molecular weight distribution.
EVA is an elastomeric polymer that produces materials which are "rubber-like" in softness and flexibility. The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation.
Linear Low Density Polyethylene is the most flexible of the plastic sheeting films. LLDPE is a blended form of LDPE where the film has much more flexibility, tensile strength, and more conformability. It is more pliable and softer. LLDPE is used for pond liners or blended into other films to give them more flexibility and extra strength. LLDPE is used for films that need a tremendous amount of strength to absorb impacts while not tearing or puncturing
