Polythene Products Manufacturers make polythene products for use in many different industries. Just some of these industries will include:
- Agriculture & Horticulture
- Retail supply chain
- Janitorial & Hygiene
Polythene or polyethylene is the most commonly used plastic today, and is primarily used within packaging, with a yearly production of around eighty million metric tons.
The name polythene is derived from polyethylene which is a thermoplastic polymer consisting of long chains of the monomer ethylene.
Polyethylene contains the chemical elements hydrogen and carbon, and is created by the polymerization of ethane. It may also be produced by anionic addition polymerization, radical polymerization, cationic addition polymerization or ion coordination polymerization, and each of these various methods will produce a different type of polyethylene.
All these different types of polyethylene are classified into several different categories ranging from very low density polyethylene (VLDPE) to ultra high molecular weight polyethylene (UHMWPE).
Ultra high molecular weight polyethylene (UHMWPE) is extremely tough and is used for gears. Bearings, chopping boards, moving machine parts and even hip and knee replacements.
Very low density polyethylene (VLDPE) is used for food packaging, stretch wrap, frozen food bags, hoses and tubing.
Polyethylene is used all over the world and this makes it an important environmental issue. Polyethylene can be recycled but most of it ends up in landfills. It is generally considered non-Biodegradable as it may take hundreds of years for it to efficiently degrade, however it was discovered in 2008 that a type of bacteria can degrade over forty percent of the weight of the plastic bags in less than three months. This discovery was made by Daniel Burd a sixteen year old Canadian.
