Plastic Storage Containers
The benefit of using plastic as a storage material, as opposed to wood, metal
or glass, is that it can be molded or extruded into virtually any shape easily
and at a relatively low cost. Plastic storage containers vary hugely in shape,
density, color and properties for the various industries they serve, and virtually
every industry uses plastic storage containers of some kind. Storage containers
are used most often in the food, agricultural, medical-pharmaceutical and cosmetics
industries for shipping and distribution.
Fabricators and manufacturers of plastic storage containers tend to specialize
in certain industries, although many manufacturers include custom design and
molding in their list of services. Many plastic storage containers are reusable
and may last several years of continuous use, thus reducing costs associated
with other containers. Such heavy-duty containers are fabricated with high-density
polyethylene, polypropylene or, in the case of high-durability products, a
composite of polyethylene and glass or carbon fiber. Polyethylene, used for
its durability, can tolerate temperatures up to 120 degrees. Polypropylene
is a slightly stiffer plastic, and may crack in cold temperatures below 0 degrees,
although it can withstand high temperatures up to 150 degrees.
Agricultural producers need
plastic
tanks, barrels and
tubs in which to store and transport goods; cosmetics manufacturers require sealable
plastic containers for product distribution and biomedical industries take
advantage of plastic's sterile, nonporous surface for uncontaminated
storage. Plastic storage containers are invaluable especially in the foodservice
industry, in which cleanliness and preservation are crucial. The non-porous,
sterile and easily cleaned surface of plastic containers keeps food fresh,
and sealable lids keep food free from contaminants. Since plastic has a high
resistance to heat and cold, most plastics can be refrigerated and heated without
damage to the food or to the container.
