Common questions
Do these mailers require tape or glue to seal?
No. The front outside tuck closure design allows the mailer to assemble and seal in seconds without tape, glue, or staples. This reduces fulfillment time and labor costs while maintaining secure closure during shipping.
What level of crush and puncture protection does ECT-32-B provide?
ECT-32-B (32-ECT) kraft corrugated delivers excellent crush resistance and puncture protection for most literature and document shipments. It's ideal for protecting catalogs, brochures, and marketing materials that require professional presentation without excessive weight.
Can I use these for oversized documents or thick materials?
The 4" depth accommodates standard literature stacks, brochures, and bound catalogs up to 1/2" thick. For thicker materials, consider our 6" or 8" depth options. The interior dimensions allow flexibility for various document types.
Are these mailers eco-friendly?
Yes. These kraft corrugated mailers are 100% recyclable and made from sustainable kraft material. The natural brown finish appeals to environmentally conscious consumers and reinforces your brand's sustainability commitment.
