1 ,2mm 0.5mm-4mm Grey Board 70*100cm Sheets Straw Board Paper Kappa Board for Boxes

In the architectural design of premium packaging, the substrate is the foundation upon which luxury is built. Our comprehensive range of Grey Board, including versatile Straw Board and the superior surface of Kappa Board, provides the essential toolkit for creating rigid boxes of unparalleled quality. Available in the highly practical 70*100cm sheet size and a critical spectrum of thicknesses—from the delicate 0.5mm for intricate layers to the robust 4mm for maximum structural support—this collection is engineered for brands and converters who define excellence.

The core of our product line is the classic Grey Board, a material celebrated for its exceptional rigidity and cost-effectiveness. For applications demanding a premium printing surface directly on the substrate, Kappa Board offers a brilliantly smooth, white-coated face, ideal for vibrant, high-resolution graphics. Complementing these is the Straw Board, an eco-conscious choice known for its distinctive natural hue and remarkable durability, often selected for its unique aesthetic and sustainable appeal. The availability of these variants ensures that for every rigid box requirement—be it for electronics, cosmetics, or high-fashion apparel—there is an optimally suited material.

The true strength of this range lies in its profound customizability. While the 1.2mm thickness serves as an industry-standard workhorse for countless box walls and inserts, our capability to supply boards from 0.5mm to 4mm unlocks limitless design potential. This allows for the engineering of complex, multi-layered structures. Imagine a jewelry box with a thin, pliable 0.5mm inner liner for a velvet-covered insert, seamlessly integrated within a rigid 2.5mm main shell, all crafted from the same family of materials for perfect compatibility. This granular control over thickness, combined with a wide GSM (Grammage) range, empowers designers to precisely calibrate the weight, stiffness, and tactile feel of the final product.

A fundamental feature across all types and thicknesses is the material's inherent rigidity and stability. The boards exhibit outstanding resistance to bending and warping, even under fluctuating environmental conditions. This ensures that the meticulously crafted rigid boxes maintain their perfect geometric form from the production line to the end customer, preserving the luxurious unboxing experience. The surface, whether the natural grey/brown of strawboard or the coated white of kappa, provides an excellent base for a multitude of finishing processes, including precision die-cutting, foil stamping, embossing, and lamination with specialty papers or fabrics.

The applications are as diverse as the material range itself. This portfolio is the definitive choice for:

 Building the foundational structure for premium consumer goods.

 Providing superior protection for smartphones, watches, and high-end accessories.

 Creating structured interiors that securely hold products in place.

 Offering both the main structure and delicate, compartmentalized interiors.

 Ensuring long-term protection for valuable documents and publications.

We support your innovation with practical flexibility. Samples are available for testing and prototyping. Furthermore, we offer customization not just in thickness and material type, but also in sheet size, allowing you to optimize material yield and reduce waste in your production process.

In essence, our 0.5mm-4mm Grey, Straw, and Kappa Board portfolio is more than just raw material; it is a collaborative, enabling partner in the creation of premium packaging. It provides the structural integrity required for protection and the flawless base necessary for breathtaking aesthetics, allowing designers and manufacturers to push the boundaries of what is possible with rigid box construction.
