Click to Fully Enlarge YUPO paper 5 sheets Yupo is a non-porous, acid free pH neutral, synthetic paper which is machine made from 100% polypropylene. (fully recyclable) It is completely waterproof, stain-resistant and is an intriguing alternative to traditional watercolour papers, particularly due to its strength and lifting properties. The super smooth surface allows you to create lovely textures and because it can be wiped clean (even when dry) you have the option to return to specific areas and redo them or indeed wipe everything away and start again! Like magic. Yupo paper is exceptionally strong, semi opaque and has an incredibly smooth surface. This paper easily resists tearing or buckling meaning there is no need to stretch or treat in any way before you start work. Since Yupo is a polypropylene (PP) plastic film, it is fully recyclable and will remain inert in any approved landfill. If safely incinerated in a modern incinerator with an atmosphere of excess oxygen, it will yield only water, carbon dioxide, and ash.
