Jiffylite Self-Seal Mailer #4
These Sealed Air 39260 envelopes are padded mailers designed for shipping small items. The self-seal closure removes the need for tape, while the lightweight construction keeps postage costs down. A white Kraft exterior accepts custom printing and contains a high percentage of recycled material. They arrive new in a carton of 100.
Suits senders needing quick, cushioned dispatch
Businesses posting documents, samples or lightweight goods benefit from the integrated bubble layer and seamless bottom. The side-seam design adds strength for regular use. Buyers who require larger formats, rigid board-backed mailers or non-adhesive closures should look at other options.
Holds flat items up to the #4 envelope size
The internal cushioning absorbs knocks during transit for typical office contents such as contracts, media or small parts. Capacity ends at the mailer’s fixed dimensions, so bulkier or heavier objects will exceed its protective limit. Each carton supplies 100 mailers for sustained shipping volume.

Questions about this item
What size items fit inside the 9 1/2 x 14 1/2 envelope?
The #4 mailer measures 9 1/2 by 14 1/2 inches, so documents or flat goods up to those dimensions will fit before sealing.
Can I run these mailers through an older folder-inserter machine?
The self-seal closure and seamless bottom are designed for hand sealing; they are not rated for automatic folder-inserter equipment.
How do I confirm the bubble cushioning is intact after packing?
Press the sealed mailer — the fully laminated bubbles should feel firm and evenly distributed with no flat spots.
