Are these mailers waterproof?

No. The kraft paper outer resists light moisture but is not waterproof. Use a poly mailer or add a plastic sleeve for rain-exposed shipments.

Small, flat items such as jewelry, phone cases, cables, cosmetics and documents. The bubble lining takes up space, so bulky or boxed items will not fit.

Do they have a self-seal strip?

Yes. Each mailer has a peel-and-seal adhesive strip. Press firmly along the full edge, and add packing tape in cold or humid conditions.

The kraft paper outer is recyclable in many curbside programs, but check local rules because the bubble lining is plastic. Some areas require separating the layers.

Are they tamper-evident?

No. The seal can be opened and resealed without obvious signs. Use a security bag or tape for sensitive contents.

Our take on the Kraft Heat-Seal Bubble Mailers

These are manila kraft bubble mailers with a peel-and-seal adhesive strip, sold in bulk packs for mailing small, light items. The bubble lining cushions contents, and the recycled kraft paper outer keeps them light and recyclable in many curbside programs. They suit resellers, small businesses and anyone shipping jewelry, accessories or documents. Against padded envelopes with tear strips or extra-thick bubble, they are basic: the seal is quick but not tamper-evident, and the paper outer can scuff in transit. Buyers rate them average, with complaints centered on seal strength and sizing.
