Overlay paper is a highly transparent functional protective specialty paper made of high-purity wood-pulp fibers. It is pattern-free and specially designed for melamine impregnation and hot-pressing processes. Incorporated with wear-resistant components, it delivers outstanding performance in wear resistance, scratch resistance, stain resistance and chemical resistance. It serves as the core surface protective material for decorative panels such as laminate flooring, HPL compact laminates and furniture countertops.

Q1: Do customers need to perform impregnation themselves for overlay paper?
A1: Yes. We supply base paper, and panel manufacturers shall complete melamine resin impregnation followed by hot-pressing.
Q2: What specifications are available?
A2: Base weight: 23-45gsm; Wear-resistance grade: AC3/AC4/AC5; Roll width can be custom-slit.
Q3: Will it turn yellow or obscure patterns of decorative paper?
A3: Made of high-transmittance base paper. It will not turn yellow or fog under proper processes and can fully restore underlying patterns.
Q4: How to select AC grades?
A4: AC3-AC4 for residential indoor flooring; AC5 is recommended for high-traffic public areas such as shopping malls and schools.
Q5: Can I get samples? What about MOQ and lead-time?
A5: Samples are available with freight borne by customers. Regular specifications are in stock while customized items are subject to production scheduling lead-time.
Q6: Can you provide certification and test reports?
A6: ISO9001, ISO14001, FSC forest-management certificates and third-party test reports covering wear resistance, light transmittance and strength can be provided to support export customs clearance and customer factory audits.
Applications
1.Laminate Flooring Its primary application as the outermost protective layer for flooring to resist walking abrasion and improve scratch-resistance. AC3-AC4 for household use and AC5 for high-traffic commercial environments.
2.Kitchen Furniture Countertops Surface protection for countertops against oil stains, condiments and household detergents. Resists daily bumps and friction to maintain long-term aesthetic appearance.
3.HPL Compact Laminates Used as the surface layer for compact laminate panels on partitions, storage cabinets, laboratory countertops and wall claddings to meet wear-resistance requirements in public spaces.
4.Other Decorative Panels All kinds of melamine-impregnated decorative panels requiring surface wear-resistant protection to safeguard printed layers from abrasion damage.
