Types of Protective Films
What are the different types of protective film, and what are the differences between them?
LDPE, or low-density polyethylene is the most common type of
protective film. It is made from polyethylene, which is the most common type of
plastic. As you might guess from the name, there is also a high-density version
of polyethylene (HDPE), which is heavier, less flexible, and less elastic—and
therefore, not as useful for making protective film. LDPE film comes in a
variety of types, which allows it to be used for many different applications.
COEX, or Co-Ex LDPE, is short for co-extruded low-density
polyethylene. Co-extrusion means that two or more layers of plastic are created
simultaneously and formed together into a single sheet of film. For example,
one common co-ex combines a layer of black plastic with a top layer of white
plastic. This allows you to take advantage of the different characteristics of
each layer, such as combining UV reflection (white) with UV absorption (black)
to provide better overall UV protection {link to post on UV & Protective
Film}.
PVC, or polyvinyl chloride, is the best-known type of
plastic. PVC film is very elastic and has a slick surface, which makes it ideal
for many metal forming applications, among other uses.
PP, or polypropylene, is a type of plastic useful for
high-heat applications. It is dimensionally stable, which means it holds its
shape and size and does not stretch like PVC films.
PO, or polyolefin, is a plastic film used on some painted
metal surfaces and acrylic glass applications.
Paper can also be used as a surface protection film. Paper
films are dimensionally stable and can absorb some impacts.
The
different types of protective film can come in different thicknesses and
with different types of adhesives and tack levels. The numerous combinations
mean that there is a surface protection film for any application.
