The kraft bubble mailer offers two-layer protection: the outer kraft paper is rustic, strong and writable, while the inner HDPE bubble layer absorbs shocks during transit. This 50-piece pack is sized for small shipments and is specifically recommended for those topping up stock in larger quantities — webshops, makers, jewellery workshops and creative businesses.
What is included in the 50-piece pack
The pack contains 50 kraft bubble mailers, each with an outer dimension of 115×175 mm and an additional 40 mm closure flap that seals the contents. The total weight is approximately 0.66 kg, and a single mailer weighs around 12 grams. The mailers arrive in a flat bundle, easy to store on a shelf or in a drawer.
Material and bubble lining
The outer layer is made from durable kraft paper, whose classic brown tone lends the parcel a rustic, natural look. The paper accepts pen ink very well and is practically tear-resistant by hand — this is a strong paper expressly designed to withstand postal handling. Inside, an HDPE-based bubble lining absorbs shocks during transit and, combined with the kraft exterior, provides double-layer protection for the contents.
Size and use
The 115×175 mm outer dimension with a +40 mm closure flap is ideal for small items: boxed jewellery, mini cosmetics, cards, USB sticks, memory cards, small printouts, charms or collectables. The kraft exterior is especially convenient if you want to apply a handwritten address, brand stamp or custom decoration to the envelope — the material accepts pen, marker and stamp ink equally well.
Closure and opening
The +40 mm flap has a self-adhesive strip on its inner side. After removing the protective tape, the flap closes in one motion and provides a durable, tamper-evident seal. The recipient opens the envelope along the flap with a tearing motion. The seal is single-use — once opened, it does not re-stick reliably for postal shipping.
Storage and durability
Store the mailers as a flat bundle, in a dry, cool location. Avoid humid environments and direct sunlight, as these gradually weaken the adhesive strip. With proper storage the 50-piece bundle retains its quality for many months, so you can comfortably purchase a larger quantity in advance.
