Poly Mailer vs Bubble Mailer? How to Decide for Your Business

Choosing the Right Mailer for Your Business

For shipping products safely, choosing the right type of mailer matters the most. It can make a big difference in cost, protection, and customer experience. Two of the most popular shipping envelopes or mailers are bubble mailers and poly mailers. Both offer unique benefits, but they’re designed for different types of items and shipping needs.

In this blog, we will break down what bubble mailers and poly mailers are their key differences, outline their pros and cons, and help you decide which is the best fit for your business. Whether you’re shipping fragile goods or lightweight apparel, you’ll find practical tips to choose packaging that keeps your products protected and your customers happy.

What Are Bubble Mailers?

Bubble mailers are padded envelopes meant for shipping small or fragile items. These mailers are made of plastic and typically have two layers: the inner cushiony layer and the outer plain layer. The inner layer is made of plastic bubble wrap, while the outer layer is made of plastic and lacks any enhancements.

It is safe to say that bubble mailers are the fusion of the functionality of bubble wrap and poly mailers. The inner padded layer, serving as a cushion to enhance protection from impact during shipping, is an idea inspired by bubble wrap. The outer plastic layer of a bubble mailer represents the poly mailer, which we will explain further in this blog. Keep reading to learn about poly mailers.

Not only a tool of protection, but bubble wrap is also a marketing tool. It offers businesses the opportunity to consolidate their branding by allowing them to have these mailers printed with their brand graphics, logo, or messaging. Typically, these printed bubble mailers are referred to as designer bubble mailers.

What Are Poly Mailers?

Polymailer bags are also packaging similar to bubble mailers, intended to ship non-fragile small items safely. These are made of plain yet durable or heavy-duty plastic layer, thus, the prefix ‘poly’ in it. It is typically developed with a sealing closure that also helps identify whether the packaging has been tampered with. Once closed, the polymailer bags would be sealed, and opening them would damage the bags, showing signs of struggle.

Like designer bubble mailers, polymailer bags can also be printed with the brand logo, colors, graphics, or messages to make the marketing efforts more cohesive and strengthen the brand image.
Being used extensively across various industries, it is recommended to purchase poly mailers in bulk. In wholesale poly mailers cost significantly less than what they would be if purchased in smaller quantities.
