Bubble Mailer

1. Cushioning and shock absorption：The inner layer is lined with air-filled bubbles, which effectively absorb impact and vibration during transit, protecting the contents from damage.

2. Lightweight and cost-effective shipping：Bubble mailers are extremely lightweight compared to cardboard boxes, helping to reduce shipping costs calculated by weight.

3. Waterproof and moisture resistant：The outer layer is typically made of polyethylene or coated kraft paper, providing good water resistance and protecting items from moisture.

4. Self-seal design for convenience：Most bubble mailers feature a self-adhesive strip, requiring no tape for sealing. They are ready to use immediately, improving packing efficiency.
