Common questions
Can these mailers accommodate thicker or heavier products?
Yes. The 4-inch gusseted bottom expansion allows you to safely ship items up to 4 inches thick, including hardbound books, binders, and bundled catalogs. The high-strength seams and 2.5 mil polyethylene construction support products weighing up to approximately 5 pounds without compromising seal integrity.
Will labels and custom branding adhere properly to these mailers?
Absolutely. The white outer surface is specifically designed for excellent label, ink, and stamp adhesion. This makes them ideal for custom branding, barcoding, and fulfillment operations where professional presentation is critical to brand perception.
Are these mailers truly moisture and puncture resistant?
Yes. The 2.5 mil polyethylene material provides puncture, tear, moisture, and tamper resistance. The self-seal closure creates an airtight barrier that protects contents from environmental exposure during storage and multi-leg shipping routes.
How easy is it for customers to open these mailers?
The double perforation tear strip is engineered for effortless, clean opening without requiring tools or scissors. Customers can quickly access contents while the perforation design prevents accidental ripping of the mailer itself or product inside.
