Prism machine-insertable envelopes

These A-2 size envelopes measure 4.375 by 5.75 inches and come in a recycled creme sulphite stock with a vellum finish. They are built for high-volume mailings such as announcements, invitations or direct-mail pieces that run through inserting equipment. The side-seam construction and 1.75 inch rounded flap feed cleanly through most desktop and production inserters. Acid-free paper helps preserve printed contents over time.

Installation and common issues

Load the envelopes flap-down with the remoistening seal facing the feed path so the machine can moisten and seal automatically. Keep the stack aligned against the side guides to prevent skewing on the two side seams. Humidity extremes can curl the 24 pound stock and cause double-feeds or jams. Static buildup in dry environments may also lead to misfeeds; an anti-static brush or ioniser helps.

Capacity and headroom

Each box contains 500 envelopes and weighs 5.5 pounds, while a master carton holds 2500 pieces for larger runs. The 24 pound weight handles single or multi-page inserts without tearing at the seams. Very thick booklets or rigid enclosures can exceed the flap seal strength and cause burst seams. Extremely high-speed insertion lines may outpace the remoistening dwell time, resulting in unsealed flaps.

Questions about this item

How do I confirm the envelopes feed correctly through my inserting machine after loading them?

Run a test batch and verify each envelope feeds without jams, the 1.75 inch rounded flap closes cleanly, and the remoistening seal activates evenly across the vellum finish.

What comes in the box and do I need to purchase sealing fluid or moisture pens separately?

The box contains 500 machine insertable announcement envelopes with remoistening seals already applied; no additional sealing fluid or pens are required.

Should I choose the 24 pound recycled creme vellum finish or a different weight and colour for high volume announcement mailings?

The 24 pound recycled creme sulphite with vellum finish is the only weight and colour offered in this 500 count box, designed for standard announcement use.
