Quality Park QUAR1460 Tyvek Envelope 9x12 White 100-pack

Product Description

The QUALITY PARK QUAR1460 is a Tyvek open-end envelope measuring 9 x 12 inches, sold in a box of 100. Each envelope is constructed from DuPont Tyvek, a spunbonded olefin material that resists tearing, puncturing, and moisture without adding significant weight to a mailpiece. The Flap-Stik closure seals securely without moisture activation, and a patented release strip allows the recipient to open the envelope cleanly without tearing into the contents. At 2.32 pounds per box, the per-unit weight is low enough to help keep postage costs in check on bulk mailings.

These envelopes are suited for mailing catalogs, multi-page documents, contracts, and other flat materials that require physical protection during transit. The open-end format allows easy insertion of standard letter-size and slightly oversized documents. Both office shipping departments and mail-room professionals commonly stock this size for outbound document and media mailings where paper envelopes would risk tearing or moisture damage.

Installation Notes

No tools are required to prepare or seal these envelopes. Remove the release liner from the Flap-Stik adhesive strip, fold the flap over, and apply firm pressure along the full length of the flap for a secure seal. Avoid touching the adhesive surface before sealing to maintain full bond strength. Store unused envelopes in a cool, dry location away from direct sunlight to preserve the adhesive.
