When it comes to protective mailing solutions, bubble mailers are a go-to choice for eCommerce brands, retailers, and small businesses alike. But not all mailers are the same. At eSupplyStore.com, two of our most popular options are Kraft bubble mailers and poly bubble mailers, each offering its own set of advantages.
So, how do you decide which one is right for your shipping needs? Let’s break it down.
What Are Kraft Bubble Mailers?
Kraft bubble mailers are made from a heavy-duty golden brown Kraft paper exterior, lined with bubble cushioning inside. These mailers offer a classic look and are often favored for their eco-friendly appeal and professional appearance.

Advantages of Poly Bubble Mailers:
Waterproof and moisture-resistant
Tear-proof and puncture-resistant

Which Mailer Should You Choose?
If your business prioritizes eco-conscious shipping or branding with a classic, natural look, Kraft bubble mailers are an excellent option. They're also ideal for dry environments and businesses shipping soft or non-breakable items.
On the other hand, if your shipments require extra durability, moisture protection, or you ship in rougher conditions, poly bubble mailers will likely be the better choice.
