The BUSINESS SOURCE BSN04649 is a catalog-size mailing envelope measuring 10 x 13 inches, built for sending flat documents, catalogs, and large-format materials through standard mail channels. Constructed from 28 lb paper stock, the envelope provides enough rigidity to protect contents during transit without adding unnecessary weight. The press-and-seal self-closing flap eliminates the need for moisture activation, allowing fast, clean closure with a single press. Each box contains 100 envelopes, making it a practical stock item for office supply rooms, shipping departments, and mailrooms that handle high document volume on a regular basis.
This envelope is suited for professional office environments, shipping and receiving departments, and any operation that regularly mails catalogs, contracts, reports, or multi-page documents. The 10 x 13 inch format accommodates standard letter and legal sheets without folding. The self-seal closure speeds up bulk mailing runs, reducing prep time compared to traditional gummed flaps. These envelopes are sold by the box and fit into standard envelope storage and dispensing setups used in most commercial mailroom configurations.
Designed as a standard catalog-size envelope suitable for general office mailing of documents, catalogs, and flat materials requiring a 10 x 13 inch format.
No tools required for use. Store envelopes flat in a dry environment to preserve the integrity of the press-and-seal adhesive strip. Avoid exposing unsealed envelopes to humidity or direct contact with other adhesive surfaces prior to use, as premature activation will compromise the seal. For bulk mailing, verify postage requirements with the applicable carrier before processing.
