the science, art and technology of enclosing or protecting products for

- Physical protection - The objects
enclosed in the package may require protection from, among other things, shock, vibration,
compression, temperature, etc.
- Barrier protection - A barrier from oxygen, water vapor, dust, etc.,
is often required.
- Containment or agglomeration - Small
objects are typically grouped together in one package for reasons of
efficiency. For example, a single box of 1000 pens requires less physical
handling than 1000 single pens. Liquids, powders, and granules
- Information transmission - Packages
and labels communicate how to use, transport, recycle, or dispose of the package or product.

- Secondary packaging is outside the primary
packaging – perhaps used to group primary packages together.
- Tertiary packaging is used
for bulk handling, warehouse
storage and transport shipping.
