Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene . Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar .
Polypropylene – Polypropylene can be made a cast film, biaxially oriented film (BOPP), or as a uniaxially oriented film. Polyester – BoPET is a biaxially oriented polyester film. Nylon – BOPA/BON is a Biaxially Oriented Polyamide/Nylon - (Commonly known as Nylon) Polyvinyl chloride – film can be with or without a Plasticizer
Banknotes of the Australian dollar in a wallet. In 1988, Australia was the first country to introduce polymer banknotes for circulation. Polymer banknotes are banknotes made from a synthetic polymer such as biaxially oriented polypropylene (BOPP).
An alpha-olefin (or α-olefin) is an alkene where the carbon-carbon double bond starts at the α-carbon atom, i.e. the double bond is between the #1 and #2 carbons in the molecule. Alpha-olefins such as 1-hexene may be used as co-monomers to give an alkyl branched polymer (see chemical structure below), although 1-decene is most commonly used ...
Metallized boPET film, 32 layers of ~14 μm thickness each. BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation.

Synthetic paper is usually made out of either biaxially oriented polypropylene (BOPP) or high-density polyethylene (HDPE). The applications include paper for labels (thus that can bond with ink) and non-label paper. The products can be highly water resistant, flexible, durable and tear resistant. [1]
BOPP: a biaxially oriented polypropylene (PP) film Other polyolefins : typically made out of high density polyethylene (HDPE), low density polyethylene (LDPE), PP plastic resins Plastic films in general are made out of plastic resins by a plastics extrusion process and can be made out of one single type of plastic material, a blend of different ...
Tenterframe technology is used to produce a variety of “heat-set” products, with biaxially oriented polypropylene (BOPP) being the most common (heat-setting is a process whereby a film is reheated in a constrained state such that the shrink properties are destroyed).
