What is a Bubble Mailer?

A bubble mailer is a type of padded envelope. It’s designed to provide extra protection to items during shipping. The interior of these mailers is lined with bubble wrap, cushioning the contents against shocks and impacts. They come in various sizes, including common dimensions like 4×6, 4×7, 4×8, and 4×9 inches, suitable for different types of items, from jewelry and CDs to books and small electronics.

How Much Does a Bubble Mailer Weigh?

The weight of a bubble mailer can vary depending on its size and the material it’s made from. Here are some general guidelines:
