Sustainable Paper for Printing

Sustainable paper for printing is a functional packaging paper produced by applying water-based repulpable barrier coatings onto base papers such as kraft paper, white paperboard, and kraft board. Unlike traditional PE-coated paper and aluminum-plastic composite paper, where plastic layers are difficult to separate from paper for recycling, the coating on this product disperses and hydrolyzes during repulping, allowing paper fibers to be recycled normally through standard paper recycling systems without special sorting. The product provides multiple barrier functions including oxygen barrier, moisture barrier, grease resistance, and water resistance. It is a core material for replacing plastic and aluminum-plastic composite films. The product is available in heat-sealable and non-heat-sealable types, in natural brown and white colors. The weight range covers 45 to 220 grams. Most grades comply with food contact safety standards.

The core value of sustainable paper for printing lies in the combination of high barrier protection and paper recyclability. In terms of barrier performance, the product offers excellent oxygen barrier, moisture barrier, and grease and water resistance. It reduces oxygen and moisture ingress, delaying oxidation and moisture damage to contents. Selected performance indicators approach the level of aluminum-plastic composite films. In terms of environmental attributes, the water-based coating disperses during repulping, achieving high fiber recovery rates and complying with domestic and international packaging recycling regulations. In terms of processing compatibility, the paper surface is smooth and supports flexo and offset printing. Heat-sealable grades can be heat-sealed directly into bags without additional plastic lamination, compatible with automatic form-fill-seal equipment.
