Water-repellent paper rucksacks

It all starts with wood from scandinavia. It is there that the wood gets sourced by means of sustainable forest management. The wood gets cut down to lengths, stripped of its bark, and finally shredded. Lastly, the wood undergoes a cellulose extraction by means of a sulphate process which gives the core of material: natural cellulose fibre. The natural cellulose fibre gets blended with a non-woven is impregnated with polymer microparticles. The cellulose fibre undergoes a tanning process that makes the material water repellent and washable.
