These 9 1/2 x 13 x 2 inch kraft expandable self-seal envelopes are built from 40 lb paper stock and feature a peel-strip adhesive closure that shields the glue line from dust and debris until the moment of sealing — no moisture activation required and shelf life is preserved until use.

The 2" gusseted sides expand to accommodate documents, catalogs, booklets, flat-pack components, and multi-piece shipments that exceed standard envelope capacity, making them well suited for e-commerce fulfillment, retail distribution, office supply operations, and general warehouse outbound shipping.

End-loading construction keeps contents secure and the kraft finish presents a clean, professional appearance for both customer-facing and internal shipments. Each case contains 250 envelopes and ships via parcel carrier.
