Ship it Safe & Easy: How to Mail a Bubble Mailer

Bubble mailers, those trusty lightweight envelopes with built-in cushioning, are a popular choice for shipping a variety of items.

They're affordable, convenient, and offer some protection for your goods during the product's transit.

However, for the uninitiated, the process of mailing a bubble mailer can raise a few questions.

You don’t have to be worried about it. We will walk you through everything you need to know to ensure your bubble-wrapped package arrives safely at its destination.

Step 1: Finding the Required Size

The first step is choosing the right size bubble mailer for your item.

It's a balancing act: you want a perfect fit to prevent items from shifting around, but not so tight that it tears or bursts during sealing.

See the following tips to make things happen.

Measure your item meticulously:

Grab a measuring tape and get precise! Length, width, and height are all important. Don't forget to factor in any additional packing materials you might use, like tissue paper or bubble wrap, for delicate items.

Consider the shape:

Oddly shaped items might require a slightly larger mailer to accommodate their curves. For example, if you're sending a rolled-up poster, you'll need a longer mailer than you would for a flat book.

Check the size chart:

Most bubble mailer manufacturers provide size charts on their websites or packaging. These charts recommend mailer dimensions based on the size of your item. For instance, a size 0 mailer might be ideal for a small jewelry box, while a size 10 mailer could comfortably accommodate a pair of shoes.

Step 2: Packing for Protection

safeguarding your items for shipment

Once you have your mailer, it's time to pack your item securely. Here are the insights to ensure a smooth packaging process for your bubble mailer and poly bubble mailers.

Wrap it with care:

For delicate items like jewelry, figurines, or electronics, use tissue paper or bubble wrap to provide an extra layer of cushioning. Gently wrap your item, making sure all sides are covered.

Remember, creating a soft cocoon will dampen the effects of shocks or bumps during transit.

Fill the gaps strategically:

If there's extra space within the mailer after wrapping your item, don't leave it empty. Why? Because empty space allows your item to move around, potentially leading to damage.

You better fill the gaps with packing peanuts, crinkled paper, or air pillows.

These packing materials will help keep your item snug and secure within the mailer.

Some common packing materials that can be utilized are:

Packing peanuts:

These lightweight, biodegradable puffs are a popular choice for filling voids. However, be mindful that some shipping services may have restrictions on their use.

Crinkled paper:

This is a readily available and eco-friendly option. Simply crumple up sheets of newspaper or packing paper to create a protective buffer.

Air pillows:

Another small inflatable cushion that is a great way to fill empty spaces without adding significant weight.

Sealing Precaution:

Most bubble mailers have a self-sealing adhesive strip for easy closure.

  • Before sealing, ensure the strip is clean and free of any debris that might prevent a secure seal.

  • Press the adhesive strip firmly along the entire length to create a tight closure.

A well-sealed mailer keeps out dust and moisture and ensures your item stays put during its journey.

Step 3: Addressing and Postage – The Essentials

Now that your package is prepped, it's time to tackle the addressing and postage. The steps can be breakdown as:

Understanding the Envelope vs. Package Distinction:

The key factor here is thickness. The United States Postal Service (USPS) considers anything under ¾ of an inch thick to be an envelope, while anything thicker is classified as a package. This distinction affects postage costs.

Choosing the Right Postage:

Lightweight Envelopes (1 oz. or less):

If your bubble mailer qualifies as an envelope and weighs 1 ounce or less, a single forever stamp (currently $0.58) will suffice.


For thicker bubble mailers or those exceeding 1 ounce, you'll need to choose a shipping service. Popular options include First Class Mail (fast and affordable for lighter packages), Priority Mail (faster with tracking and insurance), Media Mail (discounted rates for books, music, and educational materials), and Retail Ground (an economical option for heavier items).

Finding Postage:


You can purchase stamps at your local post office or many retail stores.

Online Postage:

Several online platforms allow you to purchase and print postage labels directly from your computer. This can save time and often offers discounted rates.

Addressing Your Mailer:

  • Write the recipient's address clearly and completely in the center of the mailer. It is advised to include their name, street address, apartment number (if applicable), city, state, and zip code.

  • In the top left corner of the mailer, write your own return address. This ensures your package gets back to you if there's a delivery issue.

Step 4: Sending It On Its Way

With your bubble mailer addressed and stamped (or labeled), you have a few options for sending it off:

  • Visit your local post office and drop it off at the counter.

  • For pre-stamped or pre-labeled mail, you can utilize blue collection boxes located throughout most communities.

Step 5: Tracking and Insurance

For added peace of mind, consider these options. It's optional but would be helpful in case of uncertainty.

  • Tracking:

Many shipping services offer tracking numbers that allow you to monitor your package's progress.

  • Insurance:

For valuable items, purchasing insurance can provide financial protection in case of loss or damage.

Be Mindful of:

Before you mail anything, be sure to check the USPS guidelines for restricted or prohibited items. Some common examples include hazardous materials, perishables, and firearms.
