PAPER AND PAPERBOARD PACKAGING

Systems
There are many examples today of a total systems concept involving one packaging company acting in partnership with the food manufacturer in an integrated system from the point of packing and processing to the point of sale.
Paper and paperboard based packaging systems for food products implies
consideration of:
• the functional needs of packaged preserved foods
• how these needs are met by paper and paperboard based materials and
the packaging made from such materials
• packaging machinery
• integration of food processing with packaging, storage and distribution.
One of the best examples of this type of packaging system is the aseptic packaging of milk and juice products in paperboard based liquid packaging.
The term packaging system may also be used in a more limited way where a
packaging material supplier, working in partnership with a product manufacturer, supplies packaging material, leases the packaging machinery and takes
responsibility for technical support and maintenance of the machinery.

Environmental profile
Paperboard has a low environmental impact in that the main raw material, wood,
is naturally sustainable (Fig. 8.22). Wood is derived from trees and in order to
grow naturally trees need:
•
•
•
•
sun (energy)
soil
water
air (carbon dioxide).
Wood is derived from forests. Forests are essential for the well being of the
world environment by:
•
•
•
•
reversing the greenhouse effect
stabilising climate and water levels
preventing soil erosion
storing solar energy.
The commercial use of wood for paper and board needs is met by sustainable
forest management which:
• ensures replenishment of trees
• provides habitats for animals, plants and insects
• promotes biodiversity
