Envelope Dimensions and Quantity

This open-side mailer measures 4.25 x 6.5 inches and ships in a box of 500 envelopes. The 24 lb white sulphite stock carries SFI certification and a vellum finish for a professional feel. Two side seams under construction provide reliable strength for daily mailing tasks.

Spot Seal and Perforated Flap

A spot remoistening seal on the large flap secures the envelope without additional adhesives or equipment. The integrated perforation allows the recipient to tear the flap off cleanly for reply or filing purposes. No window is present, keeping contents fully concealed during transit.

Postal Handling Constraints

The open-side format suits insertion by hand or machine but offers no built-in tracking or padding for fragile items. Each box weighs 6 lbs, and a master carton contains 4000 envelopes for high-volume operations. Users requiring opaque security tinting or windowed addressing must select a different product.

Questions about this item

Will the spot remoistening seal on the large flap lose adhesion over time?

The remoistening seal activates with moisture each use; store the box in a cool, dry place to keep the adhesive effective for the 500-envelope supply.

At what volume does the 24# white sulphite paper show wear from repeated handling?

The 24# sulphite stock resists tearing during normal mailing; heavy daily runs through automated inserters will abrade the vellum finish faster than light office use.

How much heat builds up when a laser printer runs 500 envelopes continuously?

Standard laser fusers warm the 4.25 x 6.5 envelopes; allow the printer to pause between batches so the paper stays flat and the spot seal remains intact.
