Stiff Paperboard Inner Supports

For heavier items or products that require a rigid "skeleton" within their packaging, our Stiff Paperboard Inner Supports provide the ultimate structural reinforcement. We combine high-hardness corrugated board with grayboard to create supports that offer incredible crush resistance. Our Stiff Paperboard Inner Supports are engineered to distribute pressure evenly, preventing the outer carton from collapsing in high-volume warehouses. With 11 years of manufacturing experience, we have developed composite structures that provide the strength needed for industrial and export-grade packaging.

As your production partner, we ensure that every one of our Stiff Paperboard Inner Supports is manufactured to within a 1mm tolerance. We offer a 30-day warranty against structural failure, reflecting our rigorous testing and use of high-quality raw materials. Our monthly capacity of 200W units means we can easily handle large industrial orders while maintaining the precision required for high-end electronics. We provide free structural consultation to help you minimize weight while maximizing protection. Trust our factory-direct expertise to safeguard your products from the warehouse floor to the customer's door.
