Sunmum Grey Board Paper is a substrate product designed specifically for high-end packaging, book binding, cultural and creative products, and industrial materials. Made from carefully selected raw materials and environmentally friendly accessories, combined with innovative processes for refinement, it combines the advantages of flatness, stiffness, and cost-effectiveness, meeting customers' dual demands for quality and cost.

Analysis of Core Advantages

1. Straight as a ruler, worry free processing

• Process guarantee: Through intelligent temperature control drying system and four pressure calendering technology, the paper fibers are uniformly shaped, eliminating the pain points of traditional gray board paper that are prone to warping and deformation.

Application value: The yield rate of post production processes such as printing, die-cutting, and laminating is increased by 15%, reducing losses caused by uneven substrates and assisting in efficient production.

2. Upgraded stiffness and doubled texture

Structural innovation: Adopting a high-density core layer and reinforced surface layer composite process, the stiffness is increased by 30% compared to ordinary grey board paper, and the compressive strength of the finished packaging box reaches 1.5 times the industry standard.

Visual expression: The finished product has sharp edges and a tough touch, giving high-end texture to gift packaging, hardcover books, and other products, enhancing the brand image.

3. High cost-effectiveness and controllable cost

• Raw material optimization: By scientifically proportioning, the cost of raw materials is reduced while ensuring performance, and the price is 8% -12% lower than similar products.

• Loss reduction: The flat characteristics reduce cutting waste, and 1 ton of board can produce 3% -5% more finished products, significantly saving costs in long-term use.

4. Recommended application scenarios

Premium packaging: luxury gift box, electronic product lining, highlighting a crisp texture.

Printed products: album covers, hardcover book cases, flat surfaces to ensure printing accuracy.

• Commercial display: Display rack backboards, signage substrates, strong support and not easily deformed.

5. Environmental Protection and Certification

Sunchrysanthemum grey board paper has passed SGS certification and FSC forest certification, using water-based environmentally friendly adhesive, and complies with the EU REACH regulation. Each batch of products undergoes a quality inspection process, providing comprehensive testing reports on bending strength, smoothness, moisture content, and other aspects, ensuring that the quality is qualified.
