INCPEN (incpen.org) – the Industry Council for research on Packaging & the Environment - has produced a guide that helps manufacturers, retailers and pack designers tackle the problem of Unintentional Product Residue (UPR), the waste in a pack which a consumer either can’t get out, or can’t be bothered to get out or doesn’t know is there.

Following a proposal made by Boots UK to help us understand the issue, INCPEN and WRAP – the Waste and Resource Action Programme - commissioned a study by Leatherhead Food Research. This identified the reasons why UPR occurs for a number of products widely used by consumers and the steps that producers should consider to prevent it.
