Sparco Size 1 Bubble Mailers

Sparco Size 1 Bubble Cushioned Mailers are protective envelopes designed for shipping small items. They measure 7.50" x 12" and come in a carton of 100. The durable Kraft exterior resists tearing during transit. They suit businesses and individuals mailing flat, fragile goods.

Self-seal closure and bubble lining

The self-sealing strip closes each mailer instantly without water or glue, speeding up packing workflows. Interior bubble cushioning absorbs shocks to protect contents from impact damage. The lightweight Kraft material adds minimal mass to the shipment, helping to control postage costs. These features combine protection with packing efficiency.

Suits high-volume shippers of small items

This 100-count carton fits operations that regularly send jewellery, electronics accessories or documents needing padded protection. Buyers who need larger mailers for books or boxed products should look at bigger sizes. Shoppers wanting recycled-content packaging or non-bubble rigid mailers will need a different product line.

Questions about this item

How often will I need to replace the self-seal adhesive strip on the Sparco 74981 mailers?

Each mailer uses a single-use self-seal closure; once sealed it cannot be reopened, so you simply use a fresh mailer from the 100-count carton for the next shipment.

What limits how many 7.50" x 12" bubble mailers I can process in a sustained packing session?

The practical limit is the 100-unit carton quantity; after sealing all 100 mailers you must open a new carton to continue.

Do the Kraft bubble mailers generate noticeable heat or noise when left sealed in a warehouse all day?

No, the mailers are passive packaging with no electrical components, so they produce no heat, noise or power draw during storage or transit.
