Common questions
What does ECT-32-B rating mean for my shipping needs?
ECT (Edge Crush Test) 32 indicates this mailer resists 32 lbs per lineal inch of crushing force, sufficient protection for small-to-medium fragile items in standard parcel networks. The -B designation confirms kraft paper construction optimized for cost and sustainability.
How much assembly labor do I save with fold-and-tuck design?
One-piece fold-and-tuck mailers assemble in seconds without tape, glue, or staples, eliminating per-unit labor costs and material waste. At volume, this reduces fulfillment time by 60-80% compared to traditional taped boxes.
Will this mailer size reduce my dimensional weight charges?
Yes. The compact 4 x 3 x 2" footprint minimizes dimensional weight calculations on most carrier networks, directly lowering per-unit shipping costs and improving margin on lightweight products.
Can I order these in bulk for annual volume discounts?
Yes. Packrift offers tiered volume pricing on kraft corrugated mailers. Contact our B2B sales team for custom quotes on 500+ unit orders and freight consolidation options.
