Open Side Booklet Envelopes 9 x 12

These envelopes measure 9 by 12 inches and feature an open side design for easy document insertion. The 28 lb recycled sulphite paper has a vellum finish and a creme pastel colour. They are acid free with side seams and a remoistening seal. Each box contains 500 envelopes weighing 19.5 lbs.

Suited for archiving and bulk mailing

This product suits offices, schools or archives that need acid free storage for long term document preservation. The vellum finish works well with pen or typewriter use. Buyers who need a window envelope for address visibility should look at a different style. Anyone requiring a heavier weight stock or a peel and seal closure will not find those features here.

Acid free recycled sulphite paper

The paper is acid free to prevent yellowing and deterioration of stored contents over time. It is made from recycled pastel coloured sulphite with a vellum texture. This specification determines suitability for archival projects or standard office mailing. The 28 lb weight provides a substantial feel for professional correspondence.

Questions about this item

Will the 28# recycled sulphite paper jam in a high-volume laser printer running all day?

The 28# weight and vellum finish are designed for reliable feeding in standard office printers, though continuous high-volume use should follow the printer manufacturer's paper guidelines.

What printer settings or tray adjustments are needed for the 9 x 12 open-side format?

Select a custom 9 x 12 size in the print driver and load the envelopes flap-side down in the bypass or multipurpose tray to match the open-side orientation.

Can these acid-free envelopes safely store documents printed on older thermal or dot-matrix paper?

Yes, the acid-free recycled sulphite construction prevents chemical migration that could degrade sensitive legacy printouts over time.
