Kraft Bubble Mailers

Kraft Bubble Mailers for safe, fast shipping

A small shipment can travel through several hands, conveyor belts and delivery vans before it reaches the customer. If the packaging is too light, the contents are exposed to knocks, moisture and dirt. These kraft bubble mailers (also known as padded envelopes or bubble-lined mailers) are a practical middle ground between a basic paper envelope and a cardboard box: you get a tough outer surface, built-in cushioning and a quick closure in one packer-friendly solution.

Strong kraft paper outside, PE bubble lining inside

The outer layer is made from durable kraft paper. It is designed to cope with everyday abrasion and the kind of handling that happens in parcel networks, internal mail runs and courier delivery routes. Inside the mailer, a PE bubble lining creates a cushioned layer around the contents. This helps absorb minor impacts and reduces the risk of surface damage during transport.

The construction is especially useful for small and medium items that do not need the rigidity of a box but still benefit from padding. You avoid unnecessary extra packing material, and you keep the packing process straightforward.

Self-adhesive, self-seal closure that keeps packing moving

Every mailer has an integrated self-adhesive strip for fast sealing. There is no need for separate tape, staples or additional closing steps. Insert the item, peel off the release strip and press the flap down firmly. The self-seal closure is designed to hold securely so the contents stay protected throughout the delivery chain.
