Quality Park QUAR1580 Tyvek Envelope 10x13 Box 100

Product Description

The QUALITY PARK QUAR1580 is a Tyvek open-end envelope measuring 10 x 13 inches, sold in a box of 100. Built from DuPont Tyvek material, it resists ripping, tearing, puncturing, water, and moisture, making it a reliable choice for mailing documents, catalogs, and flat media that need protection in transit. The Flap-Stik closure seals securely without moisture, using a patented release strip for clean, easy opening on the receiving end. Lightweight construction keeps the per-piece weight low, which helps reduce postage costs on high-volume mailings. These envelopes are well suited for office supply rooms, shipping departments, and any operation that sends sensitive flat materials on a regular basis.

The QUAR1580 is intended for commercial and office environments where consistent, reliable document mailers are needed. The 10 x 13 inch size accommodates standard catalogs, presentation folders, legal documents, and multi-page flat media without folding. The peel-and-seal design eliminates the need for a wet sponge or adhesive tape, streamlining pack-and-ship workflows. Each box contains 100 envelopes, making it practical for bulk purchasing in mailrooms, print shops, or administrative supply closets.

Installation Notes

No tools are required to prepare these envelopes for use. Insert contents, peel the release strip to expose the Flap-Stik adhesive, and press the flap firmly against the envelope body for a secure seal. Do not attempt to reopen a sealed Tyvek envelope by pulling the flap, as the seal is intended to be tamper-evident; use a letter opener or scissors at the designated release strip tear zone.
