Heavy Duty Triple Wall Boxes

Capacity varies by size and board grade, but triple wall boxes are commonly rated using Edge Crush Test (ECT) or Mullen burst ratings to support heavy palletized loads, often exceeding what standard single wall corrugated can handle. Consult specifications or a packaging specialist to match the correct rating to your product weight and stacking height.

Yes, custom triple wall boxes can be produced in both short and long production runs, with turnaround typically around 7 to 10 days. This allows businesses to get precisely sized containers for irregular products, bulk shipments, or specialized industrial applications that stock sizes cannot accommodate.

Yes, heavy duty corrugated boxes including MIL-SPEC weather resistant options (such as V3c and W5c grades) are available and comply with ASTM D5118 and ASTM D4727 standards. These are commonly used for military, government, and hazardous materials shipping where durability and regulatory compliance are required.

Mullen burst strength measures how much pressure a box can withstand before puncturing, while Edge Crush Test (ECT) measures stacking strength under compression. Mullen-rated boxes are typically recommended for single-box parcel shipments, while ECT-rated boxes are better suited for palletized, stretch-wrapped freight shipments.

Yes, triple wall corrugated boxes are made from recyclable fiberboard material, similar to standard corrugated cardboard. They can be recycled through standard cardboard recycling streams after use, making them an environmentally responsible choice for heavy-duty packaging needs.

Stock box sizes are available for immediate fulfillment since they are kept in ready-to-ship inventory. Custom orders, on the other hand, generally require approximately 7 to 10 days for production before shipment, depending on order volume and specifications.
