Innovia Films ’ high barrier compostable cellulose-based material, NatureFlex NK film, has been chosen by an Italian producer, New Factor, to wrap its range of organic nuts and dried fruit – Mister Nut Bio.
Launched in 2008, NatureFlex NK film not only offers biodegradability and compostability, but also a moisture barrier approaching that of co-extruded OPP. This means it has the best moisture barrier of any single layer biopolymer film currently available, which has been achieved through Innovia Films’ unique coating technology.
Dr Fabrizio Pellegrini, Plant Director at Mister Nut Bio, said the reason for choosing NatureFlex film was because it not only protects the products, but also meets the eco-credentials for the organic range.
NatureFlex film was an obvious solution for the packaging in this application as the film begins life as a natural product – wood - and breaks down at the end of its lifecycle in a home compost bin (or industrial compost environment) within a matter of weeks. NatureFlex film also offers advantages for packing and converting such as inherent deadfold and anti-static properties, high gloss and transparency, resistance to grease and oil, good barrier to gases and aromas, print receptive surface and a wide heat-seal range.
NatureFlex films are certified to meet both the European EN13432 and American ASTM D6400 standards for compostable packaging. The wood-pulp is sourced from managed plantations from referenced suppliers operating Good Forestry principals (FSC or equivalent). NatureFlex films typically have a renewable biobased content of some 95% by weight of material.
NatureFlex™ NK is a transparent, general purpose packaging grade suitable for various applications eg dried foods (biscuits, cereals, crisps, snack bars etc). The product is also ideal for lamination to other biofilms. NatureFlex NK film is available in 20, 23, 30, 45 micron thicknesses and can be used for a variety of pack formats – VFFS, flow wrap, twistwrap and overwrap.
