McCullagh Coffee introduced a compostable pack for its Rainforest Alliance-certified Ecoverde Coffee brand that uses cellulose-based NatureFlex from Innoviamccullagh films. NatureFlex features inherent deadfold and anti-static properties, high gloss, and resistance to grease and oil. It also acts as a good barrier to gases, aromas and mineral oils and offers a wide heat-seal range, Innovia says. NatureFlex films are certified to meet the American ASTM D6400, European EN13432 and Australian AS4736 standards for compostable packaging and uses wood pulp sourced from managed plantations. The renewable biobased content of NatureFlex films typically is 95 percent by weight of material according to ASTM D6866, Innovia says.
