Common questions
Do these mailers require tape or glue to seal?
No. The front outside tuck closure with integrated locking tabs provides secure sealing in seconds without tape, glue, or staples. This speeds up fulfillment while reducing operational costs and material waste.
What makes ECT-32-B corrugated better for document protection?
ECT-32-B is a crush-resistant corrugated material that provides puncture resistance and structural integrity. The protective side flaps add additional stacking strength, ensuring documents remain pristine even during rough handling and multi-package shipments.

This mailer accommodates standard catalogs, brochures, 8.5" x 11" documents folded or flat, trade show materials, and samples up to 6" thick. It's ideal for shipping multiple documents, booklets, or promotional items without bending or crushing.
Are these mailers eco-friendly and recyclable?
Yes. These white corrugated mailers are 100% recyclable and made from sustainable materials. Using tape-free assembly also reduces overall environmental impact compared to traditional taped mailers.
