Heavy-duty mailing envelopes

These Business Source catalog envelopes measure 9 by 12 inches and use 28 lb opaque white wove paper to keep contents private. The open-ended design allows quick insertion of documents, catalogs, brochures and promotional material. A moisture-activated gummed flap provides a secure seal for transit. Each box contains 250 envelopes for high-volume mailing tasks.

Suited for bulk business mailings

Offices sending large batches of flat documents, catalogs or direct-mail pieces will appreciate the sturdy construction and easy-loading format. Buyers who need padded protection, window envelopes or peel-and-seal closures should look at other styles.

28 lb opaque white wove stock

The heavyweight wove paper delivers opacity so printed or written contents cannot be read through the envelope. This single specification determines whether the envelope meets privacy and durability requirements for professional mailings.

Questions about this item

How often will I need to reorder the 250-envelope box?

Reorder frequency depends entirely on your mailing volume; the box contains 250 envelopes and has no internal counter or expiry date.

What limits how many sheets I can put inside a single 9x12 envelope?

The 28 lb wove paper and gummed flap set the practical limit; overstuffing prevents a secure seal and risks tearing the envelope.

Will the gummed flap stay sealed in a warm, humid mailroom?

Moisture-activated adhesive is designed for normal office conditions; prolonged high humidity can soften the gum, so store the box in a dry area until use.
