7 Ply Corrugated Board

7 Ply Corrugated Board – Ultimate Triple-Wall Industrial Packaging Board

For the most extreme industrial packaging challenges, Shreelaxmi Corrugated Boxes manufactures premium 7 Ply Corrugated Board — the highest strength corrugated packaging material available. Our triple-wall corrugated board replaces timber and plywood in heavy industrial transit packaging, offering superior strength, complete recyclability, and dramatically reduced weight. As a specialist 7 ply board manufacturer, we have the technical expertise and production capability to supply this demanding grade to India's most exacting industrial packaging requirements.

Triple-Wall Technology for Extreme Load Applications

The 7-ply triple-wall board achieves its exceptional performance through the compounding effect of three independent fluted core layers. Each layer contributes its own column strength to the overall board compression resistance. When these are perfectly aligned and bonded in the production process, the result is a composite structure that can withstand compressive loads far exceeding what the constituent papers would achieve individually.

Critical to the performance of 7-ply board is the dimensional accuracy of the flute geometry across all three mediums. Any deviation in flute height or pitch misaligns the compression load path through the board, dramatically reducing BCT. Shreelaxmi's production process uses precision-profiled corrugating rolls and automated tension control to maintain perfect flute geometry consistently across production runs.

Why Choose 7 Ply Corrugated Board?

• Replaces Wood Crating: Achieves equivalent or superior structural performance to 12–18mm plywood at 80% lower weight, eliminating ISPM-15 phytosanitary compliance requirements for international exports.
• 100% Recyclable: Fully recyclable and biodegradable, meeting the sustainability requirements of international buyers and regulatory bodies.
• Custom Engineered Thickness: Board caliper can be controlled from 14mm to 22mm using different flute profile combinations to precisely match application stiffness requirements.
• UN-Certification Compatible: 7-ply board configurations can be engineered and tested to meet UN hazardous goods packaging performance standards.
• Printable Surface: Unlike timber, 7-ply board provides a printable outer surface for hazard labels, shipping marks, and product identification — directly on the primary packaging.
