Avery Dennison has joined the Truecircle, a circular economy initiative by chemicals manufacturer Sabic, and announced it will develop the first recycled polypropylene label stock (rPP), which could potentially replace widely used standard PP film.
According to Rob Groen in ‘t Wout, senior marketing manager of film for Avery Dennison Label and Packaging Materials, said that both brand owners’ requirements and regulatory changes will be addressed by the new, first-ever rPP label material.
‘Label converters will soon be able to expand further the range of applications where a sustainable material is a viable option,’ said Groen in ‘t Wout. ‘Our pilot project will make this material available during 2020. We have come a very long way with adding recycled- and sustainably-sourced products to our portfolio, and polypropylene is a very important addition.’
The new material is made via feedstock recycling (pyrolysis) of mixed post-consumer plastics waste. The full value chain, the film supplier, Avery Dennison, the converter, and brand owner need to be ISCC chain-of-custody-accredited to use resin from Sabic to make the rPP facestock, so that the material is certified as a ‘circular polymer solution’.
‘We have worked closely with Sabic to make this new material a reality, and the result is the first-ever rPP label facestock. Our initial 2020 production capacity will be expanded as new Sabic production comes on stream in 2021, and we are looking forward to seeing how quickly we can work with brand owners to replace conventional PP labels. The goal of the pilot is to generate learnings to be applied in 2021 when there will be wider availability of material,’ concluded Groen in ‘t Wout.
Polypropylene labels are widely used in food, cosmetics, and a variety of other segments, so improvements in this area can make a major contribution to sustainability. The new Avery Dennison material is food-approved, and it offers the same properties as a standard PP film. In contrast to mechanically recycled materials the chemical recycling process used to make rPP means it has the same characteristics as conventional material.
Mariya Nedelcheva, product manager rigid film at Avery Dennison, EMEA, added: ‘Some plastics such as PET are already collected with high rates, with a clean stream of high-quality material that can be recycled mechanically very well. There is not yet such a collection stream for PP, so washing and mechanically recycling in order to make a new PP film is still challenging. Among all the applications for polypropylene, the bi-oriented PolyPropylene (BOPP) used for labels is the most challenging to make from mechanical recycling. This chemical recycling process for PP is an important step forward for the labelling industry, and we’re very proud to be pioneering such an important improvement – bringing to market a sustainable PP material that is food approved, and both converts and prints well.’
