Paper Weight and Finish in Daily Use

The 28-pound white sulphite stock carries an SFI certification and delivers 92 percent brightness with a vellum finish. Under sustained mailing runs the material resists tearing and feeds reliably through insertion equipment. The remoistening seal activates consistently across large batches.

Questions about this item

Does the 28 lb paper weight and center seam hold up in a Neopost inserter running all day without jamming?

Yes, the 28 lb sulphite stock with center seam is designed for continuous Neopost machine insertion and resists tearing during high-volume runs.

Do I need a specific Neopost inserter model or any other equipment to use these envelopes?

They require a Neopost-compatible inserter that accepts 9.5 x 12.5 inch open-end catalog envelopes with a remoistening seal; no other equipment is needed.

Will the 9.5 x 12.5 inch size and remoistening seal work with older catalog envelopes I already have in stock?

The dimensions match standard catalog envelope sizing, so they stack and feed alongside existing 9.5 x 12.5 inch stock; the remoistening seal functions the same way.
