Quality Park QUA24529 Double Window Envelope Box 500

Product Description

The QUALITY PARK QUA24529 is a size 9 double-window security envelope designed for high-volume document mailing where address visibility and contents privacy are both required. Built from 24 lb white wove paper with an inside security tint, it conceals contents without sacrificing the address and return-address windows. The Redi-Seal closure uses a unique double-flap design that seals without moisture — the lower flap lifts to expose the adhesive strip, which presses firmly to seal. This eliminates pre-sealing and gumming issues common with traditional lick-and-seal envelopes. Sold in a box of 500, this SKU suits mailroom operations, billing departments, and accounts payable teams processing statement or check runs.

These envelopes are intended for standard size 9 applications where a matching window alignment allows the recipient and return addresses on the enclosed document to show through the poly windows. Typical use cases include automated check stuffing, statement mailings, remittance documents, and any correspondence where hand-addressing is not practical. The inside tint prevents document contents from showing through the envelope stock. Suitable for both manual and mechanical insertion workflows at moderate run volumes.

Installation Notes

No tools required for insertion or sealing. Store envelopes flat in a cool, dry environment to prevent the Redi-Seal adhesive strip from activating prematurely. When using mechanical insertion equipment, verify that the envelope dimensions and window positions align with the equipment feed specifications before running a full batch. Handle adhesive flap with care during loading to avoid accidental pre-sealing.
