What is Packaging?

Packaging exists to deliver products to consumers in perfect condition. Well-designed packaging meets the requirements of the product while minimising economic and environmental impacts of both the product and its package. Good packaging uses only as much of the right kind of material as necessary to perform this task.

As packaging is reduced, the range of scenarios under which product losses occur rises, until the increase in product loss exceeds the savings from the use of less packaging material. Any reduction in packaging beyond that point is a false economy, since total amount of waste in the system increases.
