The High-Performance, Sustainable Backbone for Modern Premium Packaging

In today’s global packaging landscape, brands face two non-negotiable demands: uncompromising product protection across complex supply chains, and standout brand storytelling aligned with strict global sustainability and regulatory standards. Coated Kraft Linerboard (CKLB) emerges as the definitive solution, seamlessly merging the legendary toughness of natural kraft fiber with premium printability and eco-friendly design, making it the preferred substrate for industries ranging from food and beverage to luxury goods, consumer electronics, and industrial manufacturing.

Coated Kraft Linerboard is a high-performance packaging material engineered with a dual-structure design that balances strength and functionality. At its core, it uses high-quality virgin softwood kraft fiber as the base substrate, renowned for its inherent tensile strength, tear resistance, and structural stability. This base is then treated with a precision single-side (C1S) or double-side (C2S) water-based pigment coating, typically formulated with kaolin clay and calcium carbonate, to create an ultra-smooth, uniform surface.

Available in a comprehensive grammage range from 125 g/m² to 450 g/m², our CKLB adheres to strict international standards including ISO 536 (basis weight), ISO 2758 (bursting strength), and ISO 9895 (short span compression test, SCT), ensuring consistent performance across every batch. Unlike standard uncoated kraft paper or generic paperboard, it retains the rugged durability of kraft while eliminating the limitations of porous, low-printability surfaces, delivering the best of both worlds for modern packaging needs.

The defining feature of high-strength coated kraft linerboard is its exceptional mechanical performance, which outperforms conventional packaging materials in even the harshest environments. Our product delivers industry-leading bursting strength (up to 830 kPa for heavy-duty grades), superior cross-direction SCT values, and outstanding folding endurance, with MIT fold counts exceeding 1000 cycles without cracking or delamination.

Treated with optimized water-resistant formulations, it maintains structural integrity in high-humidity, refrigerated, and frozen conditions, with controlled COBB 60 values to minimize water absorption. High plybond strength ensures the material remains intact during die-cutting, creasing, folding, and high-speed packaging operations, eliminating delamination risks and reducing production waste. This robust performance drastically lowers product damage rates during transportation and storage, cutting supply chain costs for brands worldwide.

In an era where packaging serves as a critical brand touchpoint, our coated kraft linerboard sets a new standard for packaging print performance. The precision-engineered coating creates an ultra-smooth, high-opacity surface that delivers over 95% halftone dot reproduction, enabling vibrant, true-to-life color rendering and sharp, intricate graphic details.

It is fully compatible with all mainstream printing methods, including offset lithography, flexography, gravure, and UV digital printing, and works seamlessly with solvent, water-based, and UV inks. Whether for complex brand logos, gradient color designs, fine product information, or eye-catching promotional artwork, our CKLB ensures consistent, high-quality print results. This makes it the ideal choice for retail-ready packaging, point-of-sale (POS) displays, and premium branded boxes that need to stand out in crowded retail environments.

Safety and compliance are non-negotiable in global packaging, and our food-grade coated kraft linerboard is engineered to meet the world’s strictest regulatory requirements. It fully complies with U.S. FDA 21 CFR Parts 174-176 for direct food contact, EU Regulation 10/2011 for food contact materials, and GB 4806.8-2022 national food safety standards.

Our production process uses zero fluorescent whitening agents, with low-VOC formulations and strict migration limit controls, making it safe for direct contact with dry foods, frozen goods, bakery products, and non-greasy food items. All grades are available with FSC® or PEFC certification, verifying responsible forestry sourcing, and hold ISO 9001 (Quality Management System) and ISO 14001 (Environmental Management System) certifications, ensuring full compliance with market access requirements across North America, the European Union, Southeast Asia, and beyond.

As brands worldwide accelerate their ESG commitments and zero-plastic pledges, our recyclable coated kraft linerboard delivers a truly sustainable packaging solution. Made from 100% renewable wood fibers, it is fully recyclable in standard paper recycling streams and biodegradable, eliminating the plastic pollution associated with conventional flexible packaging.

Our clean production process minimizes water and energy consumption, reduces carbon emissions, and cuts waste throughout the manufacturing lifecycle. The material’s high strength-to-weight ratio also enables lightweight packaging design, reducing overall material usage without compromising protective performance. By choosing our CKLB, brands not only reduce their environmental footprint but also meet growing consumer demand for eco-friendly, plastic-free packaging options.

Thanks to its balanced performance and customizable design, our coated kraft linerboard adapts to a wide range of packaging and display applications across industries:
