CustomBoxesNow.com has simplified the box ordering process. By offering three grades of corrugated board, you can choose the right strength for your box application. If you still have questions, please call 1-877-344-2528.
The strength of a box depends on its size and the strength of the corrugated used in its construction. The larger the box, the more strength it can hold:
STANDARD strength box: Single-wall, 32 ECT, we do not recommend exceeding 65 lbs and 75 total inches of measurement.
STRONG box: Single-wall, 44 ECT, we do not recommend exceeding 95 lbs and 95 total inches of measurement.
EXTRA STRONG box: Double-wall, 51 ECT, we do not recommend exceeding 105 total inches and 120 lbs.
Total inches can be measured by taking the outside dimensions of the box and adding them together (length, height, and width.)
