The QUALITY PARK QUA90070 is a No 6-3/4 business envelope designed for high-volume office and commercial mailing operations. Made from 24 lb white wove paper with a super-white bright finish, each envelope features a full-size, fully gummed flap engineered for compatibility with automatic envelope inserting and sealing equipment. This box contains 500 envelopes. The envelope measures 3.7 inches tall by 6.75 inches wide, making it a standard size for folded correspondence, invoices, and remittance documents. Mail room staff, office managers, and shipping departments rely on this format for consistent, professional outbound mail processing.
These envelopes are suited for both manual and automated mailing workflows in office, commercial, and institutional environments. The gummed flap design supports high-speed inserting and sealing machines, reducing hand-processing time in large mailing operations. They are appropriate for standard first-class correspondence, statements, invoices, and other folded single-sheet documents typical in business-to-business and business-to-consumer mailing programs.
Designed for use with standard automatic envelope inserting and sealing equipment that accepts No 6-3/4 size envelopes.
Load envelopes into inserting or sealing equipment according to the machine manufacturer's feed tray specifications and orientation guidelines. For manual sealing, moisten the gummed flap evenly to ensure a secure bond. Store unused envelopes flat in a cool, dry environment to prevent flap pre-sealing or paper warping.
