The SPARCO SPR74986 is a kraft bubble mailer designed for protective, lightweight shipping of documents, books, soft goods, and other items that require cushioning in transit. The exterior is constructed from durable kraft material, and the interior features bubble cushioning that absorbs impact and reduces the risk of damage during handling. A self-seal closure strip secures the package without water, glue, or additional tape. Each mailer measures 12.5 x 19 inches, making it well-suited for a range of flat and moderately bulky items. The carton contains 50 mailers. Stocking this format helps reduce per-shipment labor time on pack-out lines.
These mailers are used in warehouse pack-out operations, mailrooms, print shops, and fulfillment centers where a reliable, padded envelope is needed for outgoing shipments. The kraft exterior holds up to standard handling environments, and the interior bubble layer provides consistent cushioning for fragile or surface-sensitive items. The self-seal strip allows for fast, clean closure without additional supplies at the packing station.
Designed as a general-purpose padded shipping mailer suitable for standard mailroom and fulfillment center applications requiring kraft bubble protection.
No tools or equipment are required to use these mailers. Insert contents, peel the self-seal liner, and press the closure firmly to form a secure bond. Store unused mailers flat in a dry environment to preserve the adhesive strip. Handle the self-seal tab carefully to avoid premature activation before packing.
