Product Overview
Our Laminated Grey Board Paper Sheet is engineered with double greyboard (250–2,000 g/m²) as the core material, laminated with a high-strength film layer (PET, OPP, or bio-based alternatives) to enhance durability and visual appeal. The greyboard substrate, composed of recycled fibers, provides excellent rigidity and dimensional stability, while the lamination layer offers protection against moisture, abrasion, and chemical exposure. This hybrid design ensures boxes retain their shape during transportation and storage, while the smooth surface supports high-quality printing for branding and product information.
Core Advantages
Superior Structural Performance
The double greyboard core (250–2,000 g/m²) delivers exceptional compressive strength, withstanding up to 15 MPa of pressure (ASTM D642 standard), making it suitable for heavy-duty packaging.
The lamination layer (0.02–0.1 mm thickness) forms a protective barrier, reducing water absorption to <8% (ISO 535 standard) and extending product shelf life.

Printing & Aesthetic Excellence
The laminated surface supports CMYK/Pantone offset printing with a resolution of up to 1,200 DPI, enabling vibrant colors and intricate graphics. Optional UV varnish or embossing enhances tactile and visual appeal.
The film layer prevents ink bleeding and smudging, ensuring long-lasting print quality even in high-humidity environments.
Environmental Responsibility
The greyboard is made from 100% recycled paper (FSC-certified upon request), with a minimum 70% post-consumer waste content.
The lamination film can be formulated with recyclable PET or biodegradable PLA, aligning with EU's Single-Use Plastics Directive and China's "Double Carbon" goals.
The lightweight design reduces transportation emissions by 15–20% compared to traditional cardboard.
Customization & Versatility
Full customization in size (standard: 787×1,092 mm; custom: up to 1,600×2,500 mm) and lamination type (gloss, matte, anti-static) to meet specific packaging needs.
Suitable for die-cutting, creasing, and window patching, enabling complex box structures for luxury gift sets, electronics, and medical devices.
