Conventional plastics are available in various forms with the two most popular types being low density polyethylene (LDPE) and high density polyethylene (HDPE)
Low Density Polyethylene (LDPE)
Low density polyethylene is a soft, clear plastic which can be extruded at varying thicknesses depending on the application requirements. It is a tough film that is primarily used for bags, but can be used for other applications.
After a corona treatment to improve adhesion to the plastic, these films are able to accept printing which opens up the most common form and cost effective medium of advertising. Plain or clear L.D.P.E. bags have many applications across a broad cross section of industries.
Some of the most common applications for L.D.P.E. films:
High Density Polyethylene (HDPE)
High density polyethylene is a more rigid style of film which is suitable for different applications than Low density polyethylene films. Once again, these films are a very good print medium allowing for high quality advertising.
Some of the most common applications for H.D.P.E. films:
