Standard #10 business envelope

These #10 regular machine insertable envelopes measure 4.125 by 9.5 inches and use 24 pound white sulphite paper. The side seam construction supports reliable feeding through inserting equipment. Each box contains 500 envelopes for high volume mailing operations.

SFI certified 92 brightness vellum finish

The white sulphite stock carries SFI certification and delivers 92 percent brightness with a vellum surface. Remoistening seals activate with standard moisture for secure closure. Flap down orientation suits automated processing workflows.

Bulk packaging for inserting machines

Cartons hold 2500 envelopes across five boxes to sustain continuous machine insertion runs. No window design keeps the face clear for printed addresses or labels. Side seams under construction reduces jam risk during high speed insertion cycles.

Questions about this item

How do I load these #10 envelopes into my inserting machine without jams?

Fan the stack of 500 envelopes, align the 4.125-inch edge against the side guides, and set the machine for 24-lb paper; the vellum finish feeds best when the side seams run along the bottom.

When will I need to replace the remoistening seal adhesive?

The gummed flap stays tacky for years if the box is kept sealed and stored flat; only humidity or crushing the 500-count box degrades the seal before the envelopes are used.

At what point does the 92% brightness paper show toner offset during a long print run?

Offset appears when the fuser temperature exceeds the 24-lb sulphite rating; lowering heat or inserting a blank sheet every few hundred envelopes prevents buildup on the 9.5-inch length.
