Types of Packaging Materials Used for Industrial Food Packaging
The packaging is mostly done to hold
the contents of the package securely in order to avoid breakage and leakage and
to keep the foods from various hazards like heat, germs, moisture pickup,
moisture loss etc. There are different kinds of packages available for
different kinds of packaging. Here are the types of packaging materials used
for industrial packaging –
Plastic
Films
They are actually flexible packaging films and they are very light. They are strategically
designed to protect food and other materials against gas, heat and moisture. They
add extra weight to the foot and they fit as per the shape of material which is
being transported. They don’t take a lot of space and they have wet and dry
strengths and they are convenient for the manufacturers, consumer and retailer.
Milk and milk products are packed in these films.
Polythene
They are a lot less costly as compared
to other packaging items. They are known to be the great moisture barrier. But
they cannot control odor. So, it is important to choose high density polythene which
is stronger, thicker and better barrier against gas and moisture.
Metal
Containers
There are two types of metal
containers used for packaging – metal cans with push-on lids to store dry foods
like milk powder, dry yeast, and coffee powder, and double seam cans that store
canned foods. Double seam cans are suitable for various types of foods as they
are made of tin-plated steel or aluminum. They provide complete protection
against moisture and they are tamper proof.
