Bubble Mailer Packing Tips: Seal ‘Em Up Securely

With the increased importance of e-commmerce and online shopping, packaging and shipping have become a crucial step to be undertaken. 

Bubble mailers, with their protective padding, have become a popular choice for the transportation of delicate or valuable items. 

However, proper packing and sealing are important to maximizing the effectiveness of these padded envelopes. 

In this blog post, we’ll explore the art of packing and sealing bubble mailers, ensuring your items reach their destination in a safe and secure condition.

Choose the Right Size

Selecting the appropriate size of bubble envelopes is the first step in proper packaging. 

Choose a mailer that provides enough space for your item without excessive room for movement. 

A perfect fit minimizes the risk of damage during transit and prevents the item from shifting inside the envelope. 

Remember, an overly large mailer may lead to unnecessary movement and potential harm during shipment, so always opt for a size that perfectly accommodates your item’s dimensions.

Wrap Fragile Items Securely

For delicate or breakable items, extra layers of protection are necessary. 

Wrap the item in bubble wrap or tissue paper before placing it inside the bubble mailer. 

This additional cushioning helps absorb shocks and prevents damage from accidental impacts. 

Take the time to secure loose ends and corners with tape to ensure the protective layers stay in place throughout the journey.

Position Items Carefully

Proper placement of items within the bubble mailers is crucial for effective protection. 

Position heavier items towards the centre of the envelope, surrounded by lighter or softer materials. 

This strategic arrangement helps distribute weight evenly, reducing the risk of tears during handling. 

Remember to keep fragile items away from the edges to minimize the risk of damage during the shipping process.

Seal Openings and Gaps

Before sealing the bubble mailer:

  • Ensure there are no openings or gaps where the item could be exposed.
  • Use packing tape to secure the edges and seams, creating a barrier that protects against moisture, dust, and potential damage.
  • Be thorough in your taping, paying attention to corners, as a well-sealed package is your first line of defence against external factors.

Label Clearly

Clearly label the bubble mailer with the recipient’s address and any necessary shipping labels. 

Use a permanent marker or high-quality label to prevent smudging during transit. 

Legible and accurate labelling helps ensure that your package reaches the right destination without delays or errors. 

Include your return address as an added precaution, facilitating the return process in case of delivery issues.

Consider Double-Sealing

For added security, consider double-sealing the bubble mailer. 

Apply a first layer of packing tape along the seam and edges, and then add a second layer perpendicular to the first. 

This extra step supports the seal, making it more resistant to accidental tears or tampering.

Double-sealing not only provides extra strength but also acts as a visual indicator of potential tampering.

Protect Sharp Edges

If your item has sharp edges or corners, take extra precautions to prevent them from piercing the bubble mailer.

Use additional layers of padding or cardboard to cover and protect these areas, reducing the risk of damage to the envelope and other items inside.

Consider reinforcing these weak points with extra tape to ensure the packaging remains intact throughout the shipping journey.

Check Postal Regulations

Before sending your package, familiarize yourself with postal regulations and guidelines. 

Ensure that your bubble mailer complies with size and weight restrictions imposed by the postal service. 

Non-compliance may result in additional fees or delays in delivery. 

Paying attention to these regulations not only prevents unexpected charges but also ensures a smoother shipping process.

Use Self-Sealing Bubble Mailers

Opt for self-sealing bubble mailers for added convenience and efficiency. 

These mailers come equipped with a peel-and-seal adhesive strip, eliminating the need for additional tape. 

Simply remove the protective strip, press the edges together, and your package is securely sealed. 

This not only saves time but also provides a consistently secure seal, reducing the likelihood of tape-related issues during transit.

Track and Insure Valuable Items

For valuable or irreplaceable items, consider tracking and insuring your package. 

Many shipping services offer tracking options, allowing you to monitor the progress of your shipment. 

Insurance provides financial protection in case of loss, theft, or damage during transit. 

Keep a record of the tracking number and insurance details for easy reference and peace of mind throughout the shipping process.


Properly packing and sealing bubble mailers is an art that combines both careful planning and a commitment to safeguarding your items. 

By following these tips, you can improve the protective capabilities of bubble mailers and increase the likelihood that your packages will reach their destination in perfect condition. 

From choosing the right size to double-sealing for added security, these practices will help you master the art of packaging and ensure a worry-free shipping experience.
