The recycling of multi-layer packaging is often difficult because the individual layers have to be separated first. A strategic partnership between BASF, Sulayr, Bobst and Evertis has found a recycling option for such packaging.\u00a0<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Multilayer packaging based on polyethylene terephthalate (PET) could have a promising and sustainable future. Sulayr<\/a>\u00a0has successfully organised a Process for recycling multilayer packaging launched on the market<\/strong>which fulfils the requirement of a \"closed-loop\" and enables PET to be reused.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

BASF<\/a>, Bobst<\/a> and Evertis<\/a> support Sulayr. The companies have formed a strategic partnership in which they pool their expertise from the entire packaging value chain.<\/strong>. The centrepiece of the process is a multilayer film produced by Evertis, which consists of a PET and PE layer that is laminated on a Bobst coating system using a water-based Epotal adhesive from BASF. Sulayr utilises the waste as a raw material and thus ensures a \"closed loop\"<\/strong>. The company separates the different layers and reutilises the PET. The recycled PET is supplied to Evertis and other film manufacturers, who restart the cycle.<\/p>

The process can be used for waste from consumers (post-consumer) and industry (post-industrial) and therefore has the following advantages Potential to revolutionise the entire utility model of PET-based packaging<\/strong>. Sulayr has been able to separate different types of multilayer packaging since 2009, but the speed and cost-effectiveness of the process depends on the debonding (separation) of the films.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\"Thanks to our technologies, we are able to separate most PET-containing multilayer packaging and make the recycled PET available to the industry again as a raw material. However, we notice differences in the trays that are delivered to our company after they have been used. BASF's water-based Epotal adhesives, for example, enable quick and easy separation and high quality recyclates. This is not the case with solvent-based adhesives, for example. We are certain that an improved process can contribute to better recyclability of PET-based multilayer packaging. This would provide the packaging industry with new opportunities to overcome its existing sustainability challenges.\"<\/p>

One way to optimise the recycling process is to use all the Produce PET\/PE trays under specific conditions that ensure easy separation<\/strong>. It is precisely in this area that the partners work together: Before a new laminate is launched on the market, it is qualified by Evertis, for example, in terms of its recyclability as part of the Sulayr process. This ensures that the individual layers are easy to separate.<\/p>
