These 9 x 12 inch First Class Tyvek® envelopes are constructed from 14 lb spunbonded olefin, delivering significantly greater puncture resistance, tear strength, and moisture protection than standard paper envelopes. The self-seal adhesive strip requires no water activation or additional sealing equipment, supporting faster processing in high-volume mailing and fulfillment operations.
The printed First Class border meets USPS First Class mail presentation requirements, making these envelopes well suited for document distribution, executed contracts, marketing collateral, catalogs, and flat-item shipments. They are commonly used in legal, healthcare, e-commerce, and corporate communications environments where durability and professional presentation are both required.
Interior dimensions accommodate standard letter-size documents, folders, and flat media without folding. Each case contains 100 envelopes and ships via parcel carrier.
