Standard corrugated shipping boxes range from small 4x4x4 sizes up to 48x48x48 and overheight formats. Common sizes include 12x12x12, 18x18x18, 20x20x20, 24x24x24, and larger bulk cargo dimensions. Take 2 Direct stocks a comprehensive range of RSC, telescoping, multi-depth, and heavy-duty styles. Custom dimensions are also available for specific product or SKU requirements.

For international shipping, use a double-wall or triple-wall 20x20x20 corrugated box for added structural strength. Wrap items individually with cushioning material, fill void spaces to prevent movement, and seal all seams with heavy-duty packing tape. Clearly label the box with destination and customs information. Ensure box ECT rating meets carrier requirements for international freight.

Weight capacity varies by wall construction and ECT rating. A single-wall 20x20x20 box typically supports 40–65 lbs, while double-wall versions can handle 80 lbs or more. For heavy contents, we recommend a double-wall box with a 48 ECT or higher rating. Take 2 Direct carries both single-wall and double-wall options to match your load requirements.

Single-wall corrugated boxes consist of one fluted medium between two linerboards, suitable for lighter shipments. Double-wall boxes add an extra layer of fluting and liner for greater crush resistance and stacking strength, making them ideal for heavier or fragile items and longer transit times. Take 2 Direct offers both constructions in 20x20x20 and other standard sizes.
