Clear Plastic Tube is the most popular form of plastic used in the world. It
is a compound that has multiple uses. Besides being a component of Polyethylene
Tubing, it is commonly used in many consumer products such as clear shrink
wrap, dry cleaner bags, milk cartons and plastic shopping bags. Many toys and
even baby bottles are made out of this material. It is estimated that 80
million metric tons of it are produced annually for world wide use by
manufacturers. Certain types of polyethylene are very rigid due to a high
molecular weight and can be used to make items like chopping boards and even
bullet proof vests. Implants for hip and knee replacement are also formed out
of this very versatile form of plastic.
When in the form of
Polyethylene Tubing it is categorized as either high density, which has a
density greater than 0.084 oz per cubic inch, or low density, which weighs between
0.0814 oz and 0.0839 oz per cubic inch. In the low density form, polyethylene
tubing is very flexible and resists cracking. It is able to withstand many
different temperatures making it a good choice for food industry use. Many
restaurants use plastic containers made from polyethylene since it can handle
heat and cold without becoming brittle or warping. The most common use for the
low density form is plastic bottles which are used for drinking water. When in
the high density form, Polyethylene Tubing is more rigid. It does not bend as
well as it does in the low density form. However, because it is not as flexible
it can withstand sterilization by boiling water.
Many food manufacturers
use it for this reason as well as laboratories who must sterilize equipment
continuously. This high density form is also used to make plastic pipe although
it is not as durable as PVC pipe. Unlike rubber that can deteriorate,
Polyethylene Tubing holds up over time. Its durability makes it a well-liked
choice for many items that are created from this poly product. Items such as
garbage cans, outdoor plastic pools and playhouses for children which are
subject to the elements retain their functionality much longer than their
counterparts made from wood and metal. It is such a popular material with so
many uses that it is impossible to imagine a world without it.
