The BUSINESS SOURCE BSN42120 is a kraft catalog envelope designed for mailing and storing flat documents, catalogs, and printed materials. Measuring 9 inches by 12 inches and constructed from 28 lb kraft paper, this envelope delivers reliable strength for standard business and shipping applications. The self-seal closure features a peel-off paper liner that protects the adhesive strip from dust and contamination until use, eliminating the need for moistening. Licensed trade professionals and shipping departments will find this envelope suited for high-volume document handling. Each box contains 250 envelopes.
This envelope is well suited for offices, warehouses, print shops, and fulfillment operations that regularly mail catalogs, contracts, drawings, or flat media. The 9 by 12 inch format accommodates standard letter and legal documents without folding. The brown kraft construction resists tearing during transit and provides adequate protection for contents. The self-seal strip speeds up packaging workflows in environments where large quantities of envelopes are processed at once.
Designed as a standard-format catalog envelope suitable for general business mailing and document storage applications requiring a 9 by 12 inch flat mailer.
No tools are required for use. Peel the paper liner from the adhesive strip before pressing the flap firmly to seal. Store unused envelopes in a cool, dry location to preserve adhesive integrity. Do not expose unsealed envelopes to humidity or direct sunlight for extended periods prior to use.
