Standard #10 Business Window Envelopes

These standard #10 window envelopes are designed for high-volume office mailings. The box contains 500 white sulphite envelopes with a poly window. They suit businesses that send invoices, statements or direct-mail pieces on a regular basis.

Machine-Insertable Diagonal-Seam Construction

A diagonal seam and 24-lb stock allow the envelopes to feed reliably through automated inserting equipment. The poly window aligns with address blocks printed on the insert, so no hand-stuffing is required. This construction frees up staff time for other tasks.

Consistent 92% Brightness Under Continuous Runs

The white sulphite paper maintains 92% brightness across long print runs without yellowing. SFI-certified fibre supports sustained throughput in high-speed inserters. The vellum finish resists smudging during extended handling. Buyers needing coloured or security-tint stock will need a different product.
