Common questions
Do these mailers require tape or adhesive to seal?
No. The self-sealing design features an integrated tuck closure that requires no tape, glue, or staples. Simply fold and tuck to secure, assembly takes seconds and maintains a clean, professional appearance that enhances brand perception.
Are these mailers crush-resistant enough for heavy documents?
Yes. The ECT-32-B corrugated kraft construction provides crush resistance rated for materials weighing up to approximately 5-7 lbs, making them ideal for catalogs, booklets, and multi-page literature without risk of damage during transit.
Can I fit different document sizes in a 13x10x4 mailer?
Absolutely. The 13" x 10" interior accommodates standard letter-size documents (8.5" x 11"), half-fold brochures, and flat catalogs. The 4" depth provides flexibility for varying material thickness while maintaining structural integrity.
Are these boxes environmentally compliant for direct-to-consumer shipping?
Yes. Kraft corrugated mailers are 100% recyclable and made from sustainable materials, supporting eco-conscious brand positioning. They meet standard shipping carrier requirements and appeal to environmentally-aware customers.
