HD Double Wall Cardboard Corrugated Boxes, 40″L x 20″W x 20″H, Kraft – Pkg Qty 5

Description

HD Double Wall Cardboard Corrugated Boxes are heavy-duty shipping containers engineered for demanding logistics and storage applications. These 40″L x 20″W x 20″H kraft corrugated boxes provide superior protection for medium to large-sized merchandise during transport, warehousing, and distribution across supply chains.

Key Features & Specifications:

This package includes five (5) boxes constructed from double wall corrugated cardboard, delivering exceptional durability and crush resistance. Each box features a 275 lb. ECT (Edge Crush Test) rating, indicating robust structural integrity and load-bearing capacity suitable for stacking in warehouse environments. The natural kraft finish provides excellent printability for custom branding, shipping labels, and product identification without requiring additional surface preparation. With internal dimensions of 40 inches length by 20 inches width by 20 inches height, these boxes accommodate bulky items, machinery components, automotive parts, and commercial merchandise while maintaining stackability and optimal pallet utilization. The double wall construction consists of multiple layers of corrugated medium sandwiched between kraft linerboard, creating superior puncture resistance, compression strength, and impact protection compared to single wall alternatives. This heavy-duty design minimizes damage claims, reduces product loss, and ensures items arrive at their destination in pristine condition.

Industry Applications & User Base:

These corrugated shipping boxes serve manufacturing facilities, e-commerce fulfillment centers, third-party logistics (3PL) providers, wholesale distributors, and retail operations requiring reliable bulk packaging solutions. Manufacturing environments utilize these boxes for shipping finished goods, spare parts, and industrial equipment to customers nationwide. E-commerce businesses benefit from the large capacity for consolidating multiple items into single shipments, reducing per-unit shipping costs and dimensional weight surcharges. Automotive suppliers, HVAC manufacturers, appliance distributors, and electronics companies rely on heavy-duty corrugated containers for domestic and international shipments. Warehousing and distribution centers stock these boxes for order fulfillment, cross-docking operations, and inventory management. The kraft material accepts printing for custom branding, making these boxes ideal for businesses requiring professional presentation during final-mile delivery or customer interaction.

Selection Considerations for Industrial Cardboard Boxes:

When evaluating corrugated shipping containers, prioritize the ECT rating based on your stacking height, product weight, and shipping distance—higher ratings like 275 lb. ECT handle heavier loads and multiple pallet tiers. Verify box dimensions accommodate your typical shipments with adequate cushioning space and packing materials while avoiding oversized boxes that waste material and increase shipping costs. Consider wall thickness and construction type: double wall boxes provide superior protection for fragile, valuable, or heavy merchandise, while lighter applications may utilize single wall alternatives. Assess kraft versus bleached paper options based on branding requirements, customer expectations, and cost constraints. Evaluate minimum order quantities, bulk pricing, and supplier reliability—consistent availability and delivery speed directly impact warehouse operations and order fulfillment timelines. Check for certifications, recyclability standards, and sustainability credentials if your company maintains environmental compliance commitments or customer sustainability requirements.

What size merchandise fits in a 40″ x 20″ x 20″ corrugated box?

This box accommodates items up to 39″ x 19″ x 19″ internally, allowing standard merchandise like machinery parts, small appliances, automotive components, bundled textiles, electronics equipment, and commercial tools. Account for packing materials and cushioning when calculating usable space—internal dimensions typically leave 1-2 inches clearance around items. For heavy products, fill space with protective materials like kraft paper, bubble wrap, or foam inserts to prevent shifting during transport.

What is the difference between ECT-48 and other corrugated box ratings?

ECT (Edge Crush Test) measures a corrugated box’s ability to withstand compression forces applied perpendicular to the flute direction. ECT-48 rating (275 lb. ECT on this product) indicates the box can support 48 pounds of force per linear inch of edge crush strength. Higher ECT ratings accommodate heavier products, increased stacking heights, and longer shipping distances. ECT-32 boxes suit lighter items; ECT-48 and ECT-44 boxes handle medium-to-heavy merchandise; ECT-55 and above serve extremely demanding applications. Your ECT requirement depends on product weight, pallet stack height, and handling duration.

How do I determine if double wall boxes are necessary versus single wall options?

Double wall corrugated provides 40-50% greater crush resistance, superior puncture protection, and better impact absorption than single wall construction. Use double wall boxes for fragile products, high-value merchandise, items exposed to rough handling or extended storage, shipments traveling long distances, or goods requiring multi-tier pallet stacking.
