Partners Brand B856 Heat-Seal Bubble Mailers No 3 8 1/2x14 Kraft PK100

Partners Brand B856 Kraft Bubble Mailers

These heat-seal bubble mailers come in a pack of one hundred and measure 8 1/2 by 14 inches. The kraft exterior provides a professional look while the internal bubble lining cushions contents during transit. They are designed for single-use shipping of documents, media or small merchandise. The self-sealing closure secures the package without additional tape.

Upgrading from standard padded envelopes

Standard padded envelopes often rely on paper fibres for protection and may tear under heavier loads. These B856 mailers replace them when a water-resistant outer layer and consistent air-cellular cushioning are required. The jump is worth it for shippers who need reliable impact protection and a tamper-evident seal that cannot be reopened without visible damage. Volume shippers benefit from the bulk quantity.

Limits of the heat-seal format

The heat-seal closure creates a permanent bond so the mailer cannot be reused or easily inspected by customs without cutting it open. The fixed 8 1/2 by 14 inch dimensions restrict contents to flat or slim items; bulky or irregular objects will not fit. The kraft paper surface accepts marker or label adhesive but is not designed for direct thermal printing. Each pack contains exactly one hundred mailers.
