What Are Bubble Envelopes?
Bubble envelopes are mailing envelopes with a protective bubble lining inside. The strong outer layer provides durability while the internal cushioning helps absorb impacts during handling and delivery.
They are often used instead of boxes when shipping lightweight items that need protection but do not require rigid packaging.

Bubble-lined mailers are suitable for a wide variety of products, including:
- Documents and paperwork
- Books and printed materials
- Cosmetics and beauty products
- Jewellery and accessories
- DVDs and media products
- Small electronic devices
- Clothing accessories
- Product samples
Using the correct envelope size can help reduce movement during transit and improve protection.
