What is polyethylene resin?

There are many types of resin.  For the plastic packaging industry, polyethylene resin is commonly used. It is a type of thermoplastic used to manufacture bags, tubing, sheeting, stretch and shrink films.  It is also a flexible composite.  Polyethylene, referred to as PE, is usually a mixture of polymers and ethylene.  It has mechanical, thermal, chemical, electrical, and optical properties.  It absorbs almost no water, burns slowly and cannot be imprinted without pretreatment.  PE can become brittle when exposed to sunlight.  To avoid this a UV stabilizer must be added.
