Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. It is used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles. Polypropylene was first polymerized in 1951 by a pair of Phillips petroleum scientists named Paul Hogan and Robert Banks and later by Italian and German scientists Natta and Rehn. It became prominent extremely fast, as commercial production began barely three years after Italian chemist, Professor Giulio Natta, first polymerized it. Natta perfected and synthesized the first polypropylene resin in Spain in 1954, and the ability of polypropylene to crystallize created a lot of excitement. By 1957, its popularity had exploded and widespread commercial production began across Europe. Today it is one of the most commonly produced plastics in the world.
Polypropylene bags are bags made from the synthetic plastic polymer polypropylene, a frequently used material in consumer goods and some industrial applications. It is used for bags because it is strong, flexible, and can be made transparent. Polypropylene bags are manufactured for a variety of uses. Polypropylene is used for bags less commonly than polyethylene, another plastic polymer and the most frequently used material for disposable plastic bags and packaging, but is superior to polyethylene for bags that are meant to be reused. Typically polypropylene bags are made from 1.2 mil to about 3 mil. Polypropylene bags are a great choice for preserving freshness in your products while providing exceptional clarity for the best presentation. When used for perishable products, they can greatly extend the shelf life due to their excellent vapor and moisture barrier properties. We offer several different styles and other specialty polypropylene bags.
