Yupo is a 100% polypropylene synthetic paper. Waterproof, stain-resistant and extremely durable, this extraordinary non-absorbent surface resists tearing and buckling and remains perfectly flat, eliminating the need for soaking, stretching or taping. Yupo paper allows artists to create shapes, patterns and nuances that are impossible to achieve on conventional paper. Specifications: 200 gsm/74 lb, white, 30 inches x 10 yards.
