Common questions
Are these mailers truly waterproof and moisture-resistant?
Yes. The 2.5 mil polyethylene construction provides water and moisture resistance, protecting contents from humidity, rain, and condensation during storage and transit. The self-seal closure creates an additional moisture barrier when properly applied.
Will labels and stamps adhere properly to the red exterior?
Absolutely. The colored polyethylene surface is specifically engineered for excellent ink and label adhesion. Printed logos, stamps, barcodes, and shipping labels stick cleanly without peeling or smudging, enhancing brand professionalism.
How much does each mailer weigh when empty?
Each 2.5 mil red poly mailer weighs approximately 3.5 ounces, adding minimal dimensional weight to shipments while maintaining puncture and tear resistance under typical e-commerce fulfillment conditions.
Can these mailers be opened and resealed?
While the self-seal adhesive is designed for secure single-use closure, the mailer cannot be cleanly reopened without damaging the seal. For applications requiring resealing, consider alternative closure methods like tab-lock or button-and-loop options.
