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.

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.
