Built from DuPont Tyvek material, these envelopes measure 12 inches wide by 16 inches long and feature a self-seal closure for fast, no-moisture application. The expansion gusset allows the envelope to accommodate bulkier contents without tearing or distorting. Each box contains 100 envelopes. These are commonly used by trade businesses, service departments, and distributors shipping parts catalogs, invoices, warranty documentation, or flat components that require a durable, tear-resistant mailer.\u003c\/p\u003e\u003cp\u003eThese envelopes are suited for both residential service operations and commercial facilities that regularly ship or receive documents and lightweight materials. The 12 inch by 16 inch format accommodates standard letter-size and legal-size documents without folding. The self-seal strip eliminates the need for tape or moisture activation, making them practical for high-volume outgoing mail. Sold in a box of 100, they are appropriate for service departments, administrative offices, and trade professionals managing parts orders and field documentation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTyvek construction resists tearing, moisture, and punctures during transit\u003c\/li\u003e\n\u003cli\u003eSelf-seal closure for quick, secure sealing without tape or water\u003c\/li\u003e\n\u003cli\u003eExpansion gusset accommodates thicker or multi-page contents\u003c\/li\u003e\n\u003cli\u003e12 inch x 16 inch size fits standard and legal documents without folding\u003c\/li\u003e\n\u003cli\u003eWhite finish for clean, professional appearance\u003c\/li\u003e\n\u003cli\u003eSold in a box of 100 for high-volume use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Tyvek expansion mailing envelope suitable for general business, trade service, and parts distribution shipping applications requiring a durable, flexible mailer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo tools required.
