Triple Wall Corrugated — Wood Crate Replacement Packaging

What Is Triple Wall Corrugated?

Triple wall corrugated is the heaviest-duty construction available in corrugated fiberboard. It consists of three layers of fluted medium alternating with four sheets of linerboard, creating a seven-ply structure that can exceed 15 mm in caliper. This thick, rigid board is designed as a direct replacement for wood crates and pallets in industrial packaging applications.

Triple wall board uses heavy basis weight papers throughout — often with A-flute or C-flute profiles in the fluted layers — to achieve compression strengths that rival or exceed traditional wood packaging.

Advantages Over Wood Crating

Triple wall corrugated offers several significant advantages over wood crates and pallets for heavy-duty packaging:

• Weight reduction: Triple wall weighs substantially less than equivalent wood packaging, reducing freight costs — especially for air shipments.
• No ISPM-15 treatment required: Unlike wood packaging used in international shipping, corrugated does not require heat treatment or fumigation for phytosanitary compliance.
• Recyclability: Triple wall is fully recyclable through standard corrugated recycling streams, while wood crates often end up in landfills.
• Easier assembly: Triple wall containers can be designed to fold flat for storage and snap together without nails or special tools.
• Safer handling: No splinters, nails, or sharp edges — reducing workplace injury risk during unpacking.

Applications for Triple Wall

Triple wall corrugated is specified for the heaviest and most demanding packaging applications:

• Automotive parts: Engines, transmissions, and large assemblies shipped domestically and internationally.
• Industrial machinery: Heavy equipment components requiring maximum protection during transit and storage.
• Military and defense: Equipment containers that must meet rigorous handling and stacking standards.
• Large consumer goods: Furniture, appliances, and oversized electronics.
• Export packaging: International shipments where wood treatment requirements add cost and complexity.

Triple Wall vs. Double Wall

Double wall corrugated handles many heavy-duty applications effectively. Triple wall steps in when product weights exceed double wall capacity (roughly 120 pounds or more), when the container itself must be large enough to require exceptional rigidity, or when the packaging must replace wood crating to meet logistics or sustainability goals.

The engineering team at President Container can evaluate whether double wall or triple wall is the right specification for your application, ensuring you get the protection you need without overbuilding the package.
