Quality Park QUA11218 No. 10 Security Envelope 500 Box

Product Description

The QUALITY PARK QUA11218 is a No. 10 business envelope built for secure, moisture-free mailing. Constructed from 24 lb white wove material, each envelope features a security-tinted interior that blocks visibility of contents from outside. The double-flap design prevents premature sealing during handling — lift the lower flap and press to close, no moisture required. This self-sealing mechanism suits high-volume mailing environments where speed and content privacy are both priorities. Each box contains 500 envelopes. Installation of sealing requires no tools or adhesives beyond the built-in strip. Licensed trade distributors, office supply managers, and mailroom professionals are the primary users of this product.

The QUA11218 is suited for standard business correspondence, invoicing, and any application requiring secure delivery of sensitive documents. The No. 10 size accommodates tri-folded standard letter sheets. The security tint interior makes it appropriate for mailing checks, personal identification documents, medical correspondence, or confidential business materials. The moisture-free peel-and-press seal reduces preparation time in high-throughput mailing operations and eliminates the hygiene concerns associated with traditional gummed flaps.

Installation Notes

No tools are required to prepare or seal these envelopes. To seal, lift the lower protective flap to expose the adhesive strip, insert contents, fold the upper flap down, and press firmly along the seal. Store unsealed envelopes in a cool, dry environment to preserve adhesive integrity. Do not apply heat, moisture, or solvents to the adhesive strip prior to sealing.
