Description

These 11 x 13 x 4 inch expansion poly mailers are built from 2.5 mil polyethylene with a gusseted bottom that expands up to 4 inches to accommodate bulkier contents. The white exterior accepts labels, ink, and stamps directly, while the silver interior lining adds a clean, finished appearance to outgoing shipments.

The gusseted design makes these mailers well suited for e-commerce orders involving folded apparel, soft goods, boxed accessories, and multi-item retail fulfillment. The reinforced seams hold integrity when contents are packed to capacity, and the material resists punctures, tears, moisture, and tampering throughout the shipping process.

Each mailer closes with a pressure-sensitive self-seal strip and includes a double perforation tear strip for clean, easy opening on the recipient end. Cases contain 100 mailers and are parcel-friendly.
