Wood cellulose compostable packaging
SUSTAINERS are 100% recyclable and fully compostable packaging solutions whose raw material is created from forestry cuttings. For material recovery, viscose (soluble) is first extracted from the pulp, which is filtered through a pouring nozzle and runs into a precipitation bath, after which a transparent film of pure regenerated cellulose is produced. The Grünkunft NACHHÄLTER offer high tensile strength, grease tightness and complete taste and odor neutrality. In addition, because they are related to paper, they are fully and 100% recyclable and compostable. According to the Fraunhofer Institute, cellulose hydrate is very easy to compost under natural conditions. The biomass releases carbon dioxide, which is completely returned to the material cycle. The Grünkunft NACHHÄLTER is sustainable all around, so that not only the packaging film, but also the original closure comes from ecologically sustainable forestry. For this purpose, a corresponding paper strip is used, as well as a seal seam made of vegetable-dyed organic cotton (GOTS).
