Plastic Food Containers
Plastic is in many ways an ideal material in which to store, transport and
distribute food. It is durable rather than fragile, which cuts significantly
down on the chances of breaking and spoilage; it can easily be formed to any
shape, and it can be manufactured to be any color or transparency for food
display. Plastic food containers are invaluable in the food production 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 extreme heat and cold, most plastics can be refrigerated and heated without
damage to the food or to the container.
Food is transported in a wide variety of plastic containers. Large bulk foods
or liquids are often transported in sealed polyethylene (HDPE) drums or tubs,
while smaller portions of condiments and soft drinks are sealed in polyethylene
teraphthalate (PET). Plastic tubs, bottles and jars are usually blow-molded,
a molding process similar to glass blowing, while larger and higher density
containers are extruded or injection molded.
Many plastic food containers can be reused multiple times. For those that cannot
be reused, the Society of Plastics Industry has required specific resin identification
codes be marked on plastic product containers for recycling purposes. These
numbers are specified on the bottom of recyclable objects; they are enclosed
in a rounded triangle outlined in clockwise arrows. Most plastic food containers
are recyclable, although some types of plastic are easier to recycle and release
fewer toxins during the process than others, a fact which more and more product
manufacturers are keeping in mind when choosing what type of plastic to use.
