These 12 x 9 inch kraft booklet envelopes open along the long edge and seal with a peel-and-seal adhesive strip protected by a tear tab that shields the adhesive from dust and debris until use. The opaque 28 lb kraft construction prevents contents from being visible in transit.

The booklet-style opening accepts letter-size documents, catalogs, brochures, invoices, and flat marketing inserts without folding, making these envelopes a practical choice for corporate mailrooms, fulfillment centers, publishers, and retailers managing outbound literature or correspondence programs.

Each case contains 500 envelopes and ships via parcel carrier. The peel-and-seal closure requires no moisture or secondary adhesive, supporting consistent throughput in high-volume mailing environments.
