Bubble mailers | Sticker Mule UK

Question 1

What is the difference between a padded envelope and a bubble mailer?

Accepted Answer

Padded envelopes are typically made from Kraft paper, while [bubble mailers](https://www.stickermule.com/uk/products/bubble-mailers) are made from a durable polyethylene film. Bubble mailers are generally more flexible, making them a great option for shipping a variety of item shapes and sizes. Both options provide cushioning for protection during transit, but bubble mailers often offer a lighter-weight, sleek packaging solution.
