Peanutbutter cracks sustainability riddle

Packaging sustainability may be a tough nut to crack, but some drastic packaging weight loss has recently helped Britain’s leading peanutbutter brand Sun-Pat make massive cuts in its environmental footprint—thanks to a switch from glass packaging to lightweight “glass clear” PET (polyethylene terephthalate) jars manufactured by RPC Containers in Blackburn, England.

According to brand-owner Premier Foods, the switch from glass to the 258-, 357- and 459-ml bespoke PET jars enabled a massive 90-percent weight loss—resulting in significant carbon-footprint reduction in transporting the product from packaging lines in Holland—as well as incorporation of 50-percent PCR (post-consumer recycled) content into the brand packaging.

“With logistics regulations limiting the weight of lorry-loads, we can cut the number of vehicles required for transport and delivery,” says senior brand manager Alan Robe, crediting RPC for designing the new PET jars in a way that effectively maintains the venerable brand’s identity, while also working closely with the Dutch co-packer to ensure the product’s full compatibility with PET construction.
