BASF and BillerudKorsnäs have cooperated to develop a unique home-compostable paper laminate for flexible packaging. The multi-layer film consists of three basic components: BillerudKorsnäs‘ paper ConFlex Silk, a sealing layer made of BASF’s certified home compostable and partly bio-based biopolymer ecovio and BASF’s water-based adhesive Epotal. The new home-compostable solution has the same performance features as conventional multi-layer packaging. 

 

“We wanted to create a paper-based laminate with good heat-seal properties by using certified home-compostable components only”, says Amir Pourirani, head of global marketing Biopolymers at BASF. “In BillerudKorsnäs we found the ideal partner to develop a home-compostable solution based on paper with a broader end-of-life option for packaging while maintaining the technical performance of traditional laminates,“ he added. 

 

According to the targets of the European Strategy for Plastics in a Circular Economy all plastic packaging should be recyclable or reusable by 2030.

 

“With BASF’s certified home-compostable biopolymer and adhesive, we found the ideal components to take the next step towards another sustainable solution for flexible packaging in our portfolio”, says Markus Saari, business development manager at BillerudKorsnäs. “Our joint development represents a shift to paper-based and compostable material in order to replace traditional laminates for food packaging - meeting hygiene and barrier requirements, maintaining form and enabling many design possibilities just like conventional packaging but with the decisive added benefit that it is home-compostable.”
