Details

Kraft Bubble Mailers (PS) is a classic padded mailer made from barrier bubble (inside) laminated with kraft paper (outside). Fully laminated kraft paper and consistent air bubble structure provide outstanding strength and puncture resistance.

1.Beta’s unique Barrier Bubble
- Beta’s 10-layer co-extruded barrier bubble - with extra nylon layers inserted, our film has better air retention property than conventional ones, as nylon is denser and can significantly reduce air leak, providing better cushioning performance.

- Compared with traditional bubble, better cushioning performance (under the same external conditions) means using 30% less material, thus can effectively reduce carbon emission and be cost-saving.

- Allows for multiple times of reuse as maximum air is retained.
2. Other features
- Convenient yet secure peel and seal closure for speed and ease of packing.

- Seamless/ folded bottom provides additional cushioning and greater overall protecting strength on all sides.

- Kraft paper offers excellent surface for custom printing, and together with non-toxic/water-based ink, these all helps complement your environmentally friendly brand value.
3. Special version - bag in bag PS
- Same structure and function as fully laminated PS.

- Designed for ease of recycling: non-coated kraft paper only glued with bubble layer near the opening and bottom (instead of fully laminated), so that you can tear them separate at the point of recycling.
