Heavy Duty Cardboard Shipping Boxes
 |
These heavy duty boxes are stronger than standard boxes. They meet ECT 44 (44 lbs. per inch), which is comparable to a 250-lb. burst strength. Edge Crush Test (ECT) standards measure the amount of force a carton can withstand before the edges collapse. Shipped flat.
For box sealing tape and sealing tape dispensers, see Shipping Tape and Tape Dispensers.
