These 12 1/2 x 18 1/2 inch kraft jumbo envelopes are built from 28 lb kraft paper with an ungummed flap, giving mailers full control over closure method — tape, glue, string, or moisture-activated adhesive all work cleanly with the open-end design.
The large format accommodates blueprints, legal documents, catalogs, posters, and presentation materials that cannot be folded without damage. Print shops, architecture firms, fulfillment operations, and corporate mail rooms rely on this size for outgoing flat-item distribution and interoffice routing.
Each case contains 100 envelopes and ships via parcel carrier. The natural kraft surface stacks with consistent friction for organized flat storage, and the ungummed flap supports envelope reuse where workflows allow. Order single cases or multiples to match volume requirements.
