5 Ply Corrugated Board

5 Ply Corrugated Board – Double-Wall Board for Heavy Industrial Packaging

Shreelaxmi Corrugated Boxes is a premier manufacturer of high-performance 5 Ply Corrugated Board, the industry standard for heavy-duty and industrial packaging applications. Our double-wall corrugated board — with its twin fluted cores providing exceptional load-bearing capacity — is the material of choice for electronics, appliances, automotive parts, and export packaging. Every metre of our double-wall corrugated board is manufactured under strict quality protocols to deliver the high Edge Crush Test (ECT) and Box Compression Test (BCT) values that heavy packaging applications demand.

Double-Wall Construction: Engineering Superior Performance

The 5-ply board structure consists of three liner layers bonded to two corrugated fluted mediums in an alternating pattern. This double-wall architecture creates a composite panel with dramatically superior performance compared to single-wall equivalents. The two air-column networks created by the dual fluted cores act in tandem — when one core deflects under impact, the second absorbs the residual energy, providing a two-stage cushioning system within a single sheet of board.

This structural advantage allows packaging engineers to achieve high BCT values with lower GSM paper specifications, offering an optimized cost-to-performance ratio that is difficult to achieve with any other packaging material.

Advantages of 5 Ply Double-Wall Board

• High BCT Performance: Delivers Box Compression Test values 60–80% above 3-ply, directly enabling higher stacking heights in warehouses and transportation.
• Outstanding Puncture Resistance: The double-wall structure prevents product-edge punctures that commonly damage single-wall packaging containing sharp goods.
• Excellent Rigidity and Panel Stiffness: Maintains box shape integrity under sustained loads — critical for goods stored in warehouses for extended periods.
• Versatile Flute Combinations: BC flute for maximum stiffness and compression, EB flute for improved printability and moderate thickness.
• Compatible with Automated Lines: Manufactured to precise caliper tolerances for reliable feeding through automatic die-cutters, stitchers, and gluing machines.
