Common questions
What does ECT-32-B rating mean for my shipping operation?
ECT (Edge Crush Test) 32 means each corrugated board withstands 32 pounds per linear inch of edge crush force. This B-flute construction is ideal for lightweight to medium-weight items and provides excellent stacking performance, meaning multiple mailers can be stacked securely in transit without delamination.
How much labor time do fold-and-tuck mailers save versus traditional boxes?
One-piece fold-and-tuck design eliminates tape application, glue drying time, and staple insertion. Warehouse teams report 15, 25% faster packing speeds per unit compared to 4-flap or taped boxes, directly reducing fulfillment costs on high-volume orders.
Will these mailers increase or decrease my postage expenses?
The 8 x 6 x 4" dimension (192 cubic inches) qualifies as a small parcel size on most carrier dimensional weight formulas. Lightweight corrugated construction (versus plastic or heavier board) keeps actual weight low, minimizing surcharges and maintaining competitive shipping economics.
Are these mailers suitable for fragile items?
Yes. The double-wall protection created by the fold design provides crush resistance and impact protection for fragile goods like glassware, ceramics, and electronics. For maximum protection, combine with internal void-fill materials (air pillows, kraft paper, or bubble wrap).
