Purpose-built mailers

Partners Brand B859 Heat-Seal Bubble Mailers are sized at 12 1/2 inches by 19 inches and come in a pack of 50. They suit businesses that ship flat, lightweight items and need a self-sealing kraft envelope with internal cushioning. The heat-seal closure creates a tamper-evident seal without tape or staples.

Heat-seal constraint

The mailers require a heat-sealing machine or impulse sealer to close; they cannot be sealed by hand. This limits use to operations that already own or can justify the equipment. Without a sealer the envelopes remain open and the contents are unprotected.

Kraft construction daily use

The tan kraft exterior resists tearing and handles ink stamps or labels cleanly. The internal bubble layer adds a cushioning buffer for documents, media or small parts during transit. Flat storage before sealing keeps warehouse space tidy and the 50-count pack supports regular shipping volume.

Questions about this item

What size mailer should I choose for items that need a 12 1/2 by 19 inch envelope?

The No 6 size measures 12 1/2 by 19 inches, so it matches those dimensions exactly.

How much protection does the bubble lining give once the mailer is sealed?

The heat-seal closure locks the bubble cushioning around the contents, keeping them buffered during transit.

Does the heat-seal flap need special equipment or does it work with a standard sealer?

It is designed for hot-seal machines, so a compatible heat sealer is required to activate the adhesive strip.
