Three walls of flute, one strong box.
7 ply is triple-wall: three fluted layers between four liners. That is what lets it carry dense, heavy loads and survive the stacking and handling that crush single or double wall board.
Triple-wall construction
Three flute layers stacked for stiffness and cushioning. The result takes crush loads that fold ordinary board.

Heavy-duty is a promise about failure, so we test for it. Board is GSM-verified and every batch is burst-tested, matched to the load you told us about. The spec is saved with its board grade and test basis, so a reorder carries the same weight to the same standard.
Heavy-duty questions, answered straight.
What load can a 7 ply box take?
Triple-wall 7 ply is built for heavy and dense loads: machinery, parts, industrial goods and export consignments. Tell us the weight and we match the board grade to it, then batch-test the burst strength.
Are these boxes export-grade?
Yes. 7 ply handles the stacking, handling and long transit of sea and air freight. We can add shipping marks and handling symbols, and match board to your export weight and route.
What is the minimum order quantity?
Heavy-duty runs are quoted by size and board grade and are viable from smaller quantities than light cartons, since the value per box is higher. Send your spec for the exact MOQ.
Is the bursting strength tested?
Yes. Every batch is burst-tested, so the strength you sign off is the strength that ships. We can share the board grade and test basis with your quote.
