Neopost-compatible booklet envelopes
These open-side booklet envelopes are sized at 6" x 9" and built for Neopost inserting machines. The 24# white sulphite stock carries SFI certification and a 92% brightness rating with a vellum finish. They suit offices that run high-volume mailings through automated equipment.
Side-seam construction and remoistening seal
Two side seams placed underneath the envelope body keep the front panel flat for clean printing and reliable machine feeding. The remoistening seal activates with standard mailing equipment moisture, so no separate adhesive or tape is required during insertion.
Vellum finish on 24# sulphite paper
The 24# white sulphite paper resists curling and feeds consistently through Neopost inserters without jamming. Each box contains 500 envelopes and weighs 11 lbs, making it a practical carton quantity for daily mailroom runs. Buyers who need windowed envelopes or a different flap style will need another product.

Questions about this item
Will the remoistening seal gum dry out or need replacing after the box is opened?
The gum is factory-applied and stays usable for the life of the envelope; no replacement part is required.
What limits how many envelopes can run through a Neopost inserter without a jam?
The 24# Western Sulphite stock and side-seam construction are rated for standard Neopost feeding; the inserter's own tray capacity is the practical limit.
Does the vellum finish create extra heat or static during a full-day mail run?
The low-finish vellum surface runs cool and produces minimal static in Neopost machines, so heat and noise stay at normal inserter levels.
