What’s a Bubble Mailer?

What's a Bubble Mailer

A bubble mailer, also known as a padded envelope or bubble envelope, is a type of packaging material designed to provide protection and cushioning for items during shipping or mailing.
It is commonly used to send small, lightweight, and delicate items like jewelry, electronics, CDs, DVDs, books, cosmetics, and other similar products.
The outer layer of a bubble mailer is usually made of paper or lightweight plastic, while the inside is lined with bubble wrap.
The bubble wrap lining consists of small air-filled bubbles that act as a cushion, helping to protect the contents from damage during transit. This extra padding helps prevent items from getting scratched, dented, or broken while in transit through the postal or courier system.

As previously mentioned, bubble mailers provide an excellent solution for shipping small, lightweight items. They offer protection against bumps and shocks during transit, ensuring your items reach their destination in pristine condition.
Selecting the right size of the bubble envelope is essential. It’s crucial to ensure that your items fit comfortably inside the mailer without being too cramped or too loose.
If you’re unsure about the appropriate size, refer to the chart below for guidance:
● Small: Up to 11.75″ x 15.25″
● Medium: Up to 13.50″ x 19.00″

● Extra Large: Up to 17.50″ x 24.00″
When using bubble mailers, remember to use sufficient packing material to safeguard the items from damage. You can employ crumpled newspaper, packaged peanuts, or inflated plastic bubbles as protective measures.
Lastly, ensure to securely tape the seams of the bubble mailer to keep the packing material in place, guaranteeing the safety of your items throughout the shipping process.

Regrettably, the USPS does not offer a standardized method to determine the number of stamps needed for a bubble mailer. It is not as straightforward as stating “it requires x number of stamps to send a letter.”
Shipping bubble mailers with USPS Forever® stamps can be costly. The mailing cost for a bubble envelope is influenced by three key factors:
● The weight of your bubble mailer,
● The dimensions of the mail,
● The distance it needs to travel.
These three factors impact the shipping cost of any package sent via USPS, not limited to bubble mailers. In general, lighter and smaller mail items incur lower shipping fees.
Moreover, the distance to the destination also affects the cost of shipping. Shorter distances result in cheaper shipping expenses.
When using USPS Regular Letter mail, small and light items can be adequately covered with a single Forever® stamp to cover their postage. On the other hand, larger and heavier mail will necessitate additional stamps for postage.
In the subsequent sections, we will delve into the specific size and weight restrictions for different mail classes, along with their respective shipping costs.

Bubble Mailer: An Envelope Vs. A Package

The classification of a bubble mailer as an envelope or a package depends on its thickness. If a bubble mailer measures less than 3/4″, it is categorized as an envelope. Conversely, bubble mailers with a thickness exceeding 3/4″ are considered packages. Therefore, you can determine the classification of your bubble mailer based on its thickness.

Bubble Mailer: Envelope

Let’s discuss the postage requirements for bubble mailer envelopes.
If your bubble mailer envelope’s thickness and weight are below 3/4 inch and 1 ounce, respectively, you will only need one postage stamp valued at $0.66 or one Forever Stamp.
However, if your bubble mailer envelope weighs more than the 1-ounce limit, you will be charged an additional $0.24 for each extra ounce.

Bubble Mailer: Package

In such a scenario, the USPS offers the following options for shipping packages using bubble mailers:

● For personal items weighing less than 16 ounces in a bubble mailer, you can choose USPS First Class.

● If the bubble mailer weighs more than 16 pounds but less than 70 pounds, you have the option to use USPS Priority Mail.

Shipping a bubble mailer is a straightforward process. Here’s a step-by-step guide on how to ship a bubble mailer:
Prepare the Contents: Place the items you want to send inside the bubble mailer. Ensure that the contents are securely packed and won’t move around during transit. If there are any fragile items, consider adding extra padding or wrapping them with bubble wrap.
Seal the Bubble Mailer: Close the bubble mailer securely. Most bubble mailers come with a self-sealing adhesive strip, making it easy to seal the package. If your bubble mailer doesn’t have a self-sealing strip, use packing tape to close it securely.
Address the Bubble Mailer: On the front side of the bubble mailer, write or affix the shipping label. Include the recipient’s name, address, city, state, zip code, and any other necessary details. Make sure the label is clear and readable.
Add Postage: Determine the appropriate postage for your bubble mailer based on its weight, dimensions, and destination. Affix the required postage in the form of stamps or shipping labels on the front side of the mailer, usually in the top right corner.
Optional: Tracking and Insurance: If you want to track the package’s progress or add insurance for extra protection, consider using a shipping service that provides tracking or purchasing additional insurance.
Drop Off at Post Office or Schedule Pickup: You have two options to get your bubble mailer shipped:

1.Drop off the pre-paid and labeled bubble mailer at your local post office or a USPS drop-off location.
2.Schedule a pickup with USPS if you have a package pickup service available in your area.
Keep Shipping Receipt: If you’re dropping off the bubble mailer at the post office, ask for a shipping receipt or tracking number as proof of shipment. This will be helpful if you need to track the package or inquire about its status later.
By following these steps, you can successfully ship a bubble mailer and ensure your package reaches its destination securely and on time.

Certainly, stamps can be used on bubble envelopes, but there’s a condition: your mailer must meet all the requirements to qualify as a USPS Flat or Letter.
On the other hand, if you’re shipping a package, you’ll need a shipping label.
If you have a scale and printer at home, you can generate and affix the label yourself. Otherwise, you can take the package to the post office for assistance.


In conclusion, determining the number of stamps required for a bubble mailer depends on various factors such as its weight, dimensions, and the destination. For domestic shipments, bubble mailers that are less than 3/4 inch thick and weigh up to 1 ounce can be sent with a single Forever® Stamp or a $0.66 postage stamp. However, for bubble mailers exceeding the 1-ounce limit, additional postage is required, with an extra $0.24 charged for each additional ounce. It’s important to accurately weigh and measure the bubble mailer and check the current postage rates to ensure the correct number of stamps is affixed. Additionally, considering other shipping options and services can help optimize the shipping process and provide a smooth experience for both sender and recipient.
