Compostable Sticker Paper

Compostable sticker paper is a fully bio-based, zero-plastic, completely industrially compostable environmentally friendly functional packaging material. The product uses food-grade virgin plant fibers as the base substrate, with multiple layers of bio-based polymers such as starch-based materials and cellulose nanomaterials applied through a nano-coating curing process. This completely replaces traditional PE extrusion lamination, plastic lamination, and aluminum foil lamination processes. The product provides high oxygen barrier, high moisture barrier, strong grease resistance, and flavor retention and odor barrier performance. It solves the industry challenge where traditional packaging either offers good barrier but is not biodegradable, or is biodegradable but has poor barrier properties. The product supports both paper recycling and industrial composting, making it a premium sustainable packaging material for the food industry.

The key advantages of compostable sticker paper lie in its fully bio-based material system and complete biodegradability. The product contains no PE, PP, or other petrochemical components, no PFOA/PFAS perfluorinated substances, no optical brighteners, and no heavy metal residues. After disposal, it can be 100% industrially composted with zero residue and zero microplastics, with a very low carbon footprint. The product meets domestic plastic ban requirements and export standards including EU EN13432 and US ASTM D6400. In terms of barrier performance, the product offers excellent comprehensive barrier capabilities, effectively blocking oxygen, moisture, grease, and odors. It inhibits oxidation, moisture damage, and flavor loss in food products, significantly extending the shelf life of dry goods, cooked foods, baked goods, and frozen foods. Barrier performance is comparable to traditional plastic film and aluminum foil packaging. The paper surface is smooth and flat with good stiffness, compatible with flexo, offset, and digital printing. It supports high-speed bag-making, carton forming, die-cutting, and wrapping processes.
