Professional mail fit

These #6-3/4 poly window envelopes measure 3.625 x 6.5 inches and are built for high-volume business mailing. The white sulphite stock carries SFI certification and a 92% brightness rating for a clean, professional appearance. A blue Wesco inside tint adds document security while the diagonal seam construction supports smooth machine insertion. Each box contains 500 envelopes.

Consistent feed performance

The vellum finish reduces friction during extended print or inserting runs, helping prevent jams when processing large batches. Remoistening seals activate reliably across repeated cycles without the variability of pressure-sensitive adhesives. The poly window film holds its clarity and tension through high-speed folder-inserter passes. Diagonal seams maintain structural integrity under continuous mechanical handling.

Verify window placement

Confirm the A-style window dimensions of 1-1/8 x 4-3/4 inches align with your form layout before ordering. The window sits 3/4 inch from the left edge and 7/16 inch from the bottom, a fixed position that must match your address block. Ensure your inserting equipment accepts the 24# paper weight and flap-down orientation. Check that 4.5 lbs per box fits your storage and handling workflow.

Questions about this item

How much does a full box of 500 envelopes weigh when stored on a shelf all day?

Each box of 500 envelopes weighs 4.5 lbs, making it easy to store on standard shelving without special reinforcement.

What paper size must I already have so the address shows through the 1-1/8" x 4-3/4" poly window?

The window sits 3/4" from the left and 7/16" from the bottom, so your document must place the recipient address in that exact position.

Will the 24# vellum-finish paper jam in an older laser printer that struggles with textured stock?

The 24# sulphite sheet with vellum finish feeds reliably in most legacy laser and inkjet printers that accept standard #6-3/4 envelopes.
