Multipack adhesive cleared for PET bottle recycling

As a form of packaging for PET bottles which does not require any visible secondary shrink film packaging, Nature MultiPack has attracted much attention: The PET bottles are held together by dots of adhesive specially developed and supplied by NMP Systems GmbH (Düsseldorf, Germany), a wholly owned subsidiary of KHS GmbH (Dortmund, Germany). Nature MultiPack

In 2016 the system won the German Design Award for outstanding communication design and sustainable packing. Considerable savings in materials and practical handling distinguish the pack from all other packaging variants.

Tests conducted by the European PET Bottle Platform (EPBP) on the Nature MultiPack have now confirmed that the no-film, adhesive dots method to bundle PET bottles can be fully recycled—the dots have no adverse effect on the rPET.

The tests showed that the dots of adhesive are removed as intended by friction during the washing process. The adhesive is then separated from the PET flakes as it floats to the surface of the cleaning medium. EPBP’s interim approval is valid until June 30, 2019. Further tests which are to culminate in the issue of permanent approval will follow in the coming months.

The EPBP is a voluntary, industry-related initiative that provides PET bottle design guidelines for recycling, among other information. It assesses new PET packaging systems and technologies regarding their effect on the recycling process and tests and certifies these according to strict guidelines.  It thus supports the European PET value chain with respect to economic and ecological sustainability.
