Global chemical company BASF has found the first production application for its compostable plastic ecovio in a system solution for packaging.
The company joined forces with the Swiss Coffee Company to develop a system that consists of a coffee capsule as well as aroma-tight outer packaging.
The packaging protects the product and brewing coffee in high-pressure coffee machines, yet can still be composted.
Ecovio, which was launched by BASF six years ago, is biodegradable and compostable to the European standard EN 13432.
To date, the primary fields of application for the product have been bags for biodegradable waste, helping to cultivate fruit and vegetables in fields.
Ecovio product variants enabled the coffee company to develop coffee in compostable plastic capsules in an aroma-type barrier packaging, together with coffee machines in Switzerland under the brand name Beanarella.
The barrier packaging comprises three functional layers: an outer paper layer, a thin barrier film in the middle and an ecovio-based inner sealing layer.
The packaging has been designed to satisfy the demanding barrier requirements for coffee packaging with regard to moisture, oxygen and aroma.
