PlantPaper has been on the market since 2015 and our goal is to offer paper sleeves environmentally friendly and 100% biobased solution. Why?The general impression is that conventional FSC paper for paperpots is only made of natural wood fibers. This unfortunately is not always correct. According to third parties' analyses of a range of papers in the market, there are high percentages of oil-based polyesters (PET) or other indestructible materials in the paper. Some analyses even show well beyond 60% polyester.An example, if you use 1 pallet of paper at for instance 500kg, then 60% polyester means that you are putting 300kg Oil-based Polyester (PET) in the soil! How to scale 300kg PET: A single serve 0.5l PET bottle is average 10g each, 300kg polyester is equal to 30.000 bottles. On the other hand, our paper sleeve PlantPaper U1 is certified 100% biobased by USDA (United States Department of Agriculture), OK Bio, and DIN. And besides that, has a unique perforated pattern that provides higher air circulation to the roots, thus healthier plants.PlantPaper online catalog:https://plantpaper.com/page/catalog2019
