Measuring 9 inches wide by 12 inches long with a side-opening design, each envelope is constructed from 14-pound olefin material, the same flash-spun high-density polyethylene used in demanding industrial and commercial applications. The self-seal closure strips eliminate the need for separate adhesives or moisture activation. This product ships in packs of 100 and is suited for shipping departments, document handlers, and facilities staff who need consistent, reliable envelope performance at volume.\u003c\/p\u003e\u003cp\u003eThese envelopes are used wherever tear resistance, puncture resistance, and moisture protection are required. Typical applications include shipping critical documents, blueprints, inspection reports, permits, and other materials that cannot arrive damaged. The side-opening format is well suited for inserting flat documents and oversized sheets up to 9 inches by 12 inches. Available in plain white finish, these envelopes are appropriate for both internal routing and outbound first-class or standard mail applications in commercial, industrial, and field-service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eConstructed from 14-pound olefin for puncture and tear resistance significantly beyond standard paper envelopes\u003c\/li\u003e\n\u003cli\u003eSelf-seal pressure-sensitive closure requires no water activation or separate adhesive\u003c\/li\u003e\n\u003cli\u003eSide-opening design accommodates flat documents and sheets up to 9 inches by 12 inches\u003c\/li\u003e\n\u003cli\u003eMoisture-resistant olefin material protects contents during transit and storage\u003c\/li\u003e\n\u003cli\u003ePlain white finish compatible with standard labeling and postage application\u003c\/li\u003e\n\u003cli\u003eSold in a 100-count pack for high-volume shipping and mailing operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard flat mailing envelope compatible with USPS first-class and standard mail classes, as well as common private carrier document pouches.
