How To Determine Bubble Mailer Dimensions
First of all, it is not a big deal to figure out the dimensions of bubble mailers. Here is a formula for that.
Calculate the minimum length and width of your envelope.
Minimum length = Product length + (Product height × 2) + ¼”
Minimum width = Product width + Product height + ¼”
Using these formulas, you can easily figure out the proper dimensions of bubble mailers. In fact, you can even determine which kind of bubble mailer is going to be just perfect for you. Branded Bubble mailers are gaining a lot of popularity in the shipping industry.

Main Advantages of Using Bubble Packaging:
- Recycling Capabilities
Bubble mailers do have certain advantages over other packaging, like they are not as heavy, they use less material than cardboard boxes, and they still give a dependable cushioning effect for little parcels. But then again, they vary quite a lot when it comes to sustainability, and it can be a little confusing. For example, poly bubble mailers are made from polyethylene plastic. So they are not biodegradable. They need a special kind of plastic film recycling process and, in practice, they are rarely recycled.
- Customer Satisfaction Improvement
Why are bubble mailers ideal for shipping products? They come in a variety of colour or size options. With protection, these options leave a positive lasting impression on your customers at the time of shipment.
Using the variety of colours and sizes as part of their branding, companies can tie their slogans into the use of bubble mailers. Thus, they create a total brand experience for their customers.
- Efficient and Lightweight
Due to their lightweight bubble mailers, you can easily transport small items. They have air pockets that protect goods during transit. Therefore, these mailers are the ideal way of ensuring that fragile items get safely to their destination without any damage.
