Overview
Premium Rigid Paperboard & Greyboard ManufacturerRigid paperboard, commonly referred to as grayboard or industrial solid board, is the backbone of premium custom packaging. It is primarily chosen for high-end fashion packaging, consumer electronics, luxury cosmetics, and rigid setup gift boxes that require absolute structural stability and a flawless, refined look.
As an engineering-driven packaging manufacturer, Foho Packaging controls the quality of our rigid board from the raw material level. We utilize heavy-duty, multi-layered recycled grayboard that offers exceptional stiffness-to-weight ratios and high compression resistance. This sustainable, anti-warping material ensures your luxury box structures remain perfectly square and unyielding during global transit.
High Stiffness Metric: Superior burst-test ratings to prevent structural sagging under vertical pressure.
100% Recyclable Core: Made from premium recycled fibers, meeting global eco-friendly retail compliance.
Anti-Warping Mechanics: Climate-chamber tested to ensure flatness and dimensional tolerance controlled within 0.5 mm.
