Introduction

Padded envelopes, also known as cushioned mailers, bubble mailers or padded mailers, are a popular packaging choice for businesses and individuals alike. In this article, we will discuss an envelope size guide. These envelopes feature an outer layer made from durable materials like kraft paper or plastic, paired with a padded interior such as bubble wrap or foam. This combination provides superior protection, making them ideal for shipping delicate or valuable items.

Padded envelopes are indispensable for safely shipping items that need extra protection during transit. Combining the simplicity of a traditional envelope with added cushioning, they cater to diverse applications, from e-commerce to personal use. Choosing the right size is critical to ensuring your items arrive intact and undamaged.


Types of Padded Envelopes

Bubble Wrap Padded Envelopes

Bubble wrap padded envelopes are among the most commonly used types. The interior is lined with air-filled plastic bubbles that cushion items against shocks and drops. They’re perfect for shipping fragile goods like electronics, jewellery, or glassware.
