    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. Structural features

    - Most commonly used bubble mailers, with water-resistent and tear-proof 3 layer co-extruded PE film exterior that has excellent malleability.

    - Strong PE film and consistent air bubble structure provide outstanding strength and puncture resistance, making the bag flexible and soft yet strong enough to hold odd-shaped/ sharp-edged objects.

    - Made from 100% PE, therefore 100% recyclable.
