Sparco Cushioned Bubble Mailer 5"x10

These mailers use durable Kraft paper with interior bubble cushioning to protect contents during transit. Each unit features a self-seal closure that closes without water or glue. The lightweight design helps reduce shipping weight. They are sold in cartons of 250.

Replacing plain envelopes or tape-sealed bags

The self-seal strip removes the need for separate tape or moisture-activated adhesive, speeding up packing lines. Internal bubbles add impact protection that flat mailers lack. The upgrade is worth it when breakable items ship regularly and packing speed matters.

Check item dimensions and weight before ordering

The 5 by 10 inch outer size limits what fits inside; measure your product to confirm clearance. Verify that the self-seal adhesive meets your carrier’s acceptance standards. Ensure storage space exists for a full 250-count carton.

Questions about this item

What are the exact outer dimensions of the 5x10 mailer so I can check it fits my shelf slot?

The mailer measures 5 inches by 10 inches, giving a compact footprint that fits standard shelf slots and packing stations without overhang.

How do I seal the self-seal closure correctly, and what is the step people often miss?

Peel the protective strip fully to expose the adhesive, press the flap firmly across the entire width, and hold for a few seconds; skipping the firm press leaves a weak seal that can open in transit.

When does the interior bubble cushioning need to be replaced, and how can I tell?

Replace a mailer if the bubbles feel flat, the Kraft paper tears, or the self-seal adhesive no longer grips; each carton contains 250 new mailers so you always have fresh cushioning on hand.
