Polymailers vs. Bubble Mailers: Which One is Right for You?

Updated: Jun 8, 2023


Bubble Mailers

What are Bubble Mailers?

A bubble mailer, also known as a padded envelope or cushioned mailer, is a type of packaging designed to protect items during shipping. It consists of an outer envelope made of paper or plastic and an inner layer of bubble wrap or padding. The inner layer serves as a cushioning material to provide extra protection against impacts, shocks, and vibrations that may occur during transit.


Bubble mailers are commonly used for shipping small, delicate, or fragile items such as jewelry, electronics, cosmetics, or small accessories. The bubble wrap lining helps absorb and distribute the force of any external pressure, reducing the risk of damage to the enclosed items. The outer envelope is typically made of paper or plastic materials and may have a self-sealing adhesive strip for easy closure.


Bubble mailers offer several advantages. They are lightweight, which can help reduce shipping costs compared to heavier packaging options. They are also flexible, making them suitable for various shapes and sizes of items. Additionally, bubble mailers are convenient to use as they eliminate the need for additional packing materials such as boxes and fillers.


It's important to note that while bubble mailers provide some level of protection, they may not offer the same level of sturdiness and protection as boxes or rigid packaging options. For extremely fragile or valuable items, additional packaging precautions may be necessary.


What are poly mailers?

A poly mailer, also known as a poly bag or shipping bag, is a type of lightweight packaging commonly used for shipping and mailing purposes. It is made from polyethylene (a type of plastic) and typically features a self-sealing adhesive strip or closure mechanism. Poly mailers come in various sizes, ranging from small to large, to accommodate different items.


Poly mailers offer several advantages for shipping purposes. They are lightweight, which helps reduce shipping costs compared to heavier packaging options such as boxes. The polyethylene material provides durability and resistance to tearing, punctures, and moisture, protecting the contents during transit. Poly mailers are also flexible and stretchable, allowing them to conform to the shape of the enclosed items. This flexibility makes them suitable for shipping clothing, textiles, soft goods, and other non-fragile items.


Another advantage of poly mailers is their versatility and ease of use. They are available in different colors and can be customized with branding, logos, or labels to enhance brand recognition. The self-sealing adhesive strip makes sealing the mailers quick and convenient, eliminating the need for additional packaging materials. Poly mailers are also space-saving, as they can be stored flat when not in use, requiring less storage space compared to bulkier packaging options.


It's important to note that poly mailers may not provide the same level of protection as boxes or padded mailers for fragile or valuable items. Additional cushioning materials may be necessary for delicate or breakable items to ensure safe transport. However, for lightweight and non-fragile items, poly mailers offer a cost-effective, lightweight, and convenient solution for shipping and mailing needs.


Which is right for you?

When it comes to shipping items, choosing the right packaging is crucial to ensure the safe delivery of your products. Two popular options for shipping are poly mailers and bubble mailers, each offering unique advantages depending on the nature of the items being shipped. Understanding when to use a poly mailer versus a bubble mailer can help you make informed decisions and optimize your shipping process.


Poly mailers are ideal for shipping non-fragile items such as clothing, textiles, documents, or lightweight products that do not require extra padding or protection. They are made from a durable polyethylene material that provides resistance against tearing, punctures, and moisture. Poly mailers are lightweight, which can help reduce shipping costs, especially for large quantities or bulk shipments. They are also flexible and can conform to the shape of the enclosed items, making them a versatile option.

On the other hand, bubble mailers are designed to provide additional cushioning and protection for more delicate or fragile items. They feature a layer of bubble wrap inside the mailer, which acts as a cushion to absorb shocks and impacts during transit. Bubble mailers are suitable for items such as electronics, small glassware, jewelry, or any product that requires extra padding to prevent damage. The bubble wrap lining helps create a protective barrier around the item, reducing the risk of breakage or scratches.


When deciding between a poly mailer and a bubble mailer, consider the nature and fragility of the items you are shipping. If you are shipping non-fragile items like clothing, documents, or lightweight products, a poly mailer is a cost-effective and efficient option. Poly mailers are lightweight, easy to use, and can provide adequate protection for these types of items. They are also space-saving, as they can be stored flat when not in use.


However, if you are shipping items that are delicate, breakable, or require extra padding, a bubble mailer is the better choice. The bubble wrap lining provides a layer of cushioning to protect fragile items from potential damage during transit. Bubble mailers offer an added sense of security and peace of mind when shipping delicate items, as they minimize the risk of breakage or scratches.


It's worth noting that the decision between a poly mailer and a bubble mailer also depends on your budget and shipping requirements. Poly mailers are generally more cost-effective than bubble mailers, which may be a significant factor for businesses with a high volume of shipments. However, if the value and protection of your items are paramount, investing in bubble mailers can help ensure their safe arrival.


In summary, when to use a poly mailer versus a bubble mailer depends on the nature of the items being shipped. Poly mailers are suitable for non-fragile items that do not require extra padding, offering cost-effectiveness, lightweight construction, and convenience. Bubble mailers, on the other hand, provide additional cushioning and protection for delicate or fragile items, ensuring their safe transportation. Assess the fragility of your items, consider your budget, and choose the appropriate mailer that aligns with your specific shipping needs.
