Shipping protection for semi-fragile items

Sealed Air Jiffylite mailers use a Barrier Bubble layer of Bubble Wrap brand material to cushion low-profile products during transit. The self-seal closure secures contents quickly without tape. A seamless bottom adds strength and extra padding along the full length. Lightweight construction reduces postage costs while the Kraft exterior resists punctures and supports custom printing.

Self-seal convenience over tape-sealed alternatives

Switching from standard envelopes that require separate tape or glue cuts packing time and eliminates loose seals. The upgrade is worth it when you ship volumes of 100 or more and need consistent closure speed with integrated cushioning. The 39093 model delivers both in a single step.

Suits high-volume shippers needing integrated

Offices and e-commerce operations that dispatch semi-fragile, flat items in batches of 100 will benefit from the combined protection and speed. Buyers who require larger dimensions, heavier-duty padding or non-self-seal closures should look at other mailer styles.

Questions about this item

What size items fit inside the 8 1/2 x 12 inch mailer?

The envelope measures 8 1/2 by 12 inches, so contents must be smaller than those dimensions to allow the self-seal flap to close properly.

How do I seal the Jiffylite mailer without tape?

Peel the protective strip from the self-seal adhesive on the flap, press firmly along the entire length, and ensure no dust or packaging debris contaminates the glue line.

When should I replace a mailer instead of reusing it?

Replace any mailer showing punctures, crushed bubbles, torn kraft paper, or a flap that no longer seals completely, as cushioning and security are compromised.
