Unilever turn over a brewed leaf with corn starch to replace PP in PG Tips tea bags

Unilever, one of the world’s largest food companies, has Camellia over eco-friendly, after it said it will make the bag material for its PG Tips tea brand, sold in the UK, from a biodegradable plant-based material.

Unilever said, 'Lapsang, Souchong' to using polypropylene in its PG Tips teabags, which is used as a seal to prevent disintegration, after finding its drinkers are more concerned that polypropylene takes a long time to break down. 

Unilever claimed the move to plant-based sealants was based on "cutting edge science and technology."

Noel Clarke, Vice President Refreshment, Unilever: “After 85 years of making PG tips, we have a great understanding on how the British love their tea. The new 100 per cent plant based material we’re moving to is an innovation based on cutting edge science and technology and we’re all really excited that, starting from now, the PG tips that you know and love will come from 100 per cent plant based material from a renewable source that’s fully biodegradable.”

The move comes as companies and supermarkets look to placate perceived public concern over the use of plastics.

The replacement material is made from corn starch, making the ten billion PG Tips teabags produced every year, fully biodegradable. A knitted monkey appearing in PG Tips' television adverts became a popular cultural character in the UK, alongside its sidekick the English comedian and ceramicist Johnny Vegas.

Other global Unilever tea brands are Brooke Bond, Lipton, Bushells, Lyons, Lan-Choo, Pukka, Red Rose, Scottish and T2.
