The 5 Best 9x12 Catalog Envelopes (2023 reviews)

The ampad 9x12 catalog envelope is long-lasting, rigid and fits well with your regular usage like a dream. These are high quality envelopes. They aren't like cardboard or cardsrock by any means, but in comparison to other, more flimsy options, these are perfect. It is great for anything that you need to protect. The sticky part of the flap is close to the edge so there's no loose edge waiting to catch on something. It works and is a good size for tax returns.

These are well made and hold up well. The security lining is great so that the contents cannot be seen from the outside. It is a plain envelope. It is great for mailing documents.

Why We Like This:

Flaps prone to popping up due to poor quality adhesive
White material is strong, good adhesive and easier to work with than clasp envelopes
Envelope moisteners or moisture of any kind is required
Good envelopes, completely opaque, self-stick stays stuck

These tamper evident catalog envelopes are ideal for sending important documents through the mail. A moderately heavy 28 lb paper that the envelopes are manufactured from is heavy enough to help keep your documents inside from being creased when you mail these but light enough in weight that it's not adding a tremendous amount of postage just for the envelope. It has a scrambled blue pattern printed on the interior that conceals the contents.

The sealed envelope works very well to help speed the process along in sealing all of them. It protects critical documents or your customers' sensitive data. A pull strip makes opening the envelope straightforward and prevents you from tearing the documents inside. It's cardboard, so it's recyclable, all good there. It's great for mailing 8 x 10 pictures.
