Quality Park QUAR1790 Tyvek Envelope 12x15.5 in Box 100

Product Description

The QUALITY PARK QUAR1790 is a Tyvek open-end envelope designed for secure, professional mailing of documents, catalogs, and flat materials. Measuring 12 x 15.5 inches, each envelope is constructed from DuPont Tyvek, a spunbonded olefin material that resists ripping, tearing, and puncturing under normal shipping and handling conditions. The Flap-Stik closure seals without moisture, using a peel-and-seal strip that creates a firm bond without licking or wetting. The material is also water-resistant and moisture-resistant, protecting contents from light exposure to the elements in transit. Tyvek is significantly lighter than paper or bubble mailers of comparable size, which can reduce postage costs when mailing in bulk. Each box contains 100 envelopes.

These envelopes are suited for shipping or mailing flat items such as legal documents, catalogs, booklets, blueprints, and photographs that require a durable, tear-resistant outer layer. The open-end design allows easy insertion of flat materials. The white finish accepts address labels, stamps, and postage meter impressions cleanly. Facilities managers, mail room staff, print shops, and shipping departments working in office, commercial, or light industrial environments are the primary users of this product.

Installation Notes

Insert materials fully before engaging the Flap-Stik closure to ensure a complete seal along the full length of the flap. Peel the release liner cleanly before pressing the flap firmly down. Do not attempt to reopen a sealed envelope by pulling the flap, as the bond is intended to be permanent. Address labels and postage should be applied to the exterior face before sealing when possible.
