New Zealand-based coffee roaster, Caffe Prima will launch its fully compostable foil bags made from wood pulp and corn starch by Convex Plastics in Canada.
Caffe Prima owner Geoff Johnson said the new Econic coffee packets have been made with packaging suitable for freshly roasted beans and ground coffee.
"When you roast coffee the beans expel CO2 and continue to do that as they age unless you leave the coffee for four or five days before you bag it and then you lose flavour," Johnson said.
The foil packets of fresh coffee have a plastic one-way valve and prevent them blowing up as the carbon dioxide is released. The bag incorporates vents that are activated by internal pressure to release the gas.
The Econic bags are made by laminating together three layers of film for composting and biodegradability and the foil look is achieved by spraying the middle cellulose layer with an aluminium coating.
Caffe Prima contract roasts for a wide range of customers, including the office supplies market, reports nzherald.co.nz.
