Envelopes for documents and mailing

These Columbian COLO401 envelopes measure 9 x 12 inches and hold standard 8.5 x 11 papers without folding. The pack contains 30 white catalog envelopes made from heavyweight 28 lb paper stock. A self-seal closure uses a peel-and-press strip that requires no moisture.

Suited for office filing and home organization

The envelopes work well for contracts, catalogs, photos and reports that need to stay flat and protected. Users who need padded cushioning, window styles or a larger quantity per box should look at something else.

Self-seal closure with 28 lb kraft paper

The peel-and-press strip creates a secure seal without licking or tape, while the 28 lb paper resists tearing during handling and transport. This combination of closure type and paper weight is the specification that decides if the pack fits your workflow.
