Innovia films&rsquo compostable, cellulosebased material, natureflex&trade is helping a new zealand coffee roaster meet its commitment to being socially and environmentally responsible. Caffe prima, based in christchurch, has chosen to use &39econic&39® coffee bags.
The bags were specifically developed by new zealand converter, convex plastics, using natureflex&trade renewable and compostable films in their construction. &ldquocoffee is a very demanding product to package because maintaining freshness and taste is absolutely paramount. Packs have to be puncture and impact resistant and offer high barrier and good seal integrity to keep oxygen out and aroma in.
Coupled with this, caffe prima, was looking for a solution that was kind to the environment. Natureflex&trade ticked all the boxes as far as we were concerned,&rdquo said andrew sheerin, technical manager, convex plastics. A laminate construction was produced using three flexible films that are certified compostable and renewable &ndash a reverse printed clear natureflex&trade highbarrier metallised natureflex&trade starch based biopolymer. &ldquoachieving success with partners such as convex means that our natureflex&trade films are well positioned to provide solutions to converters and brand owners.
Especially those seeking to meet consumer demand for packaging made from renewable resources,&rdquo said robin dearnley, australia and new zealand sales manager for innovia films. Natureflex&trade films are certified to meet the american astm d6400, european en13432 and australian as4736 standards for compostable packaging.
The woodpulp is sourced from managed plantations from referenced suppliers operating good forestry principals fsc or equivalent. The renewable biobased content of natureflex&trade films is typically 95 by weight of material according to astm d6866. Natureflex&trade has been confirmed as suitable for emerging &39waste to energy&39 techniques such as anaerobic digestion, aiding the diversion of organic wastes from landfill. Natureflex&trade was an obvious solution for use in this application as the film begins life as a natural product &ndash wood and breaks down at the end of its lifecycle in a home compost bin or industrial compost environment within a matter of weeks.
