Flexible Packaging
“The high stiffness and transparency of PP gives both excellent machinability and consumer appeal. PP films can be coated or coextruded to optimise oxygen barrier properties for a particular confectionery application. All BOPP films have excellent moisture barrier performance. Low temperature sealing skins and coatings are now commonly available, again providing outstanding machinability and strong hermetic seals. Cast PP can be used to improve both these features.” So which of these are a sustainable option? Stephen says:
“From an environmental perspective, PP films offer a very low carbon footprint and are fully recyclable. Their low- density makes them the most resource efficient packaging option because of their lightweight.” Sustainability is now fundamental to the design of every
new product launched. Be that the use of mono material laminate constructions such as BOPP and Cast PP lamination, or in the reduction of a products carbon footprint using non- fossil based raw materials. In 2019, the UK produced over 300,000* tonnes of flexible plastic packaging, which is about 22%* of all UK consumer plastic waste. Of this, only 6%* of flexible plastic is currently recycled. A new collaborative fund, founded in May 2021 by Ecosurety
in collaboration with Mars, Mondelēz International, Nestlé, Pepsico and Unilever, is seeking to give value to flexible plastics so they are properly recycled. The Flexible Plastic Fund wants to incentivise flexible plastic recycling as quickly as possible. Ecosurety and the founding partners created a concept to involve everyone in the flexible plastic supply chain.
“Whether you call it flexi, flexible, soft or ‘plastic bags
and wrapping’ there are loads of ways to describe things like wrappers, packets, film and pouches. The important thing is that by working together, we can make sure it gets recycled,” says The Flexible Plastic Fund.
