Purpose-built envelopes
These A-10 announcement envelopes are designed for high-volume machine inserting jobs. They suit offices, print shops and mail houses that need a reliable stock for statements, invoices or direct-mail pieces.
Capacity and limits
Each box contains 500 envelopes, giving a long run before re-ordering. The 28 lb sulphite sheet handles standard desktop and inserter feeds cleanly, but heavier multi-page inserts may exceed the paper's stiffness envelope.
Build and daily use
White sulphite stock carries SFI certification and a 92 brightness rating with a vellum finish for crisp print contrast. Two side seams under the 1-3/4 inch rounded flap provide consistent sealing on inserting equipment and a professional look in the recipient's hand.

Questions about this item
Will these 6 x 9-1/2 envelopes feed reliably through my older inserting machine?
Yes, they are built as machine insertable with two side seams under and a 1-3/4" rounded flap down so they move smoothly through most inserting equipment.
How can I confirm the brightness level matches the 92% spec after opening the box?
Hold a sheet under standard office lighting next to a known 92% brightness reference; the white sulphite stock with vellum finish should show an equivalent clean white appearance.
Does the box of 500 include any moisture barrier or do I need to buy a separate storage container?
The box contains 500 envelopes only; no inner moisture barrier is included, so plan your own resealable container if humidity is a concern.
