Common questions
Do I need tape or other supplies to seal these mailers?
No. The self-sealing tabs are engineered to grip securely within the carton walls, creating a professional closure without tape, glue, or staples. This reduces assembly time and eliminates supply costs while maintaining a clean, branded appearance.
Can these boxes handle delicate printed materials?
Yes. The ECT-32-B corrugated construction provides excellent crush and puncture resistance, protecting literature, brochures, and samples from damage during transit. The snug-fitting tabs add additional rigidity to prevent shifting.
What's the maximum weight capacity?
These literature mailers are optimized for lightweight to medium-weight contents, typically up to 2-3 lbs depending on material density. For heavier shipments, consider a thicker corrugation grade.
Are these boxes environmentally friendly?
Yes. The ECT-32-B corrugated cardboard is 100% recyclable and made from recycled fiber content, making it an eco-conscious choice for brands committed to sustainable packaging practices.
