Common questions
Do these mailers require tape or adhesive for closure?
No. The integrated self-sealing tabs fit snugly within the carton walls when folded, creating a secure closure without tape, glue, or additional supplies. This speeds assembly and reduces packaging costs.
How much protection does ECT-32-B corrugated provide?
ECT-32-B (Edge Crush Test) corrugated is industry-standard for literature mailers, offering puncture resistance and moderate crush protection for standard documents and lightweight materials during standard shipping conditions.
Can I fit standard 8.5 x 11" literature into these 4 x 4 x 4" boxes?
Yes. 8.5 x 11" materials can be folded in half (creating 5.5 x 8.5") or rolled for compact fit. The 4 x 4 x 4" cubic volume accommodates folded literature, sample materials, or stacked catalogs efficiently.
What is the minimum order quantity?
The standard unit is a bundle of 50 mailers. This quantity is ideal for small to mid-sized e-commerce brands managing regular literature fulfillment without excess inventory storage requirements.
