Polypropylene (PP) A polypropylene bag is a high clarity, crystal clear bag which enhances the product’s image. It provides a highly protective barrier against moisture and vapors.

Plastic bottles made out of PET are currently widely replacing heavy and fragile glass bottles as reusable packaging for mineral water and lemonades. PE and PP are also being used for producing non-reusable bottles and packagings.
Polypropylene, also know as polypropene is a form of plastic just as polyethylene is. What separates polypropylene from polyethylene for starters is the fact that polypropylene can be molded in essence becoming pliable above a certain temperature.
Polyethylene is commonly categorized into one of several major compounds of which the most common include LDPE, LLDPE, HDPE, and Ultrahigh Molecular Weight Polypropylene.
Polyethylene costs more than polypropylene to make and comes in second behind polypropylene as a material choice for living hinges, a type of flexure hinge made from the same material as the rigid pieces it binds together.
Both Polypropylene and polyethylene are a form of plastic- a plastic material known as a polymer. Their molecular structure looks similar with carbons and hydrogen molecules- but then the differences arise.
Examples include polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC). Let’s look at some common plastics. Polyethylene terephthalate (PET or PETE): John Rex Whinfield invented a new polymer in 1941 when he condensed ethylene glycol with terephthalic acid. The condensate was polyethylene terephthalate (PET or PETE).
What is Polypropylene (PP), and What is it Used For? 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 is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling. In 2013, the global market for polypropylene …
PE is usually a mixture of similar polymers of ethylene with various values of n. Polyethylene is a thermoplastic; however, it can become a thermoset plastic when modified (such as cross-linked polyethylene
