Food Packaging
Packaging FactsName any material that you can think of, and it was probably used at some time as a food packaging material. Did you know?
The earliest food packaging was provided by nature in the form of gourds, shells, leaves, hollowed logs, woven grasses, and animal organs.
The first commercial cardboard box was produced in England in 1817, more than two hundred years after the Chinese invented cardboard.
Packaging Facts
The can opener was invented in 1875.
The first glass bottle-making machines were invented in the United States in 1882.
Recycling aluminum cans saves 95 percent of the energy used to make aluminum cans from virgin ore.
Functions of Packaging
Packaging Serves FOUR Functions
Containment – Products must be contained in order to be moved from the factory to the grocery store to the pantry shelf.
Functions of Packaging
Protection – Products must be protected from physical damage (e.g. drops or falls), environmental effects (e.g. water, light, or oxygen), and contaminants (e.g. dust, microorganisms, or chemicals).
Functions of Packaging
Communication – The package must attract consumers for purchase. It also communicates product information such as nutritional content, ingredients, and net weight.
Functions of Packaging
Convenience – The package must conveniently fit into the consumer’s lifestyle.
Types of Packaging

Sustainable PackagingEnvironmentally friendly packaging causes less damage to the environment. There are three types:
Reusable packaging can be cleaned and re-used. For example, glass milk bottles are reused.
Recyclable packaging is made of materials that can be used again, usually after processing. Recyclable materials include glass, metal, card and paper.
Biodegradable packaging will easily break down in the soil or the atmosphere
Primary packaging is seen at the point of sale. It needs to contain and protect the food product, as
well as display it and provide information.
Secondary packaging is the middle layer of packaging - for example a cardboard box with a
number of identical products inside.
Transit packaging is the outer container that allows easier handling during transfer between
factory, distribution centres and retailers
