Shipping with boxes can be cumbersome and isn’t always necessary. If you ship non-fragile items, how important is it that you ship them in big bulky boxes? Ecommerce shipping requires you to cut costs wherever possible, not corners, and one way to do this is to cut back on high packaging costs. And poly mailers offer a surprisingly affordable alternative to standard packaging while also taking up less space and being easier to pack and ship. 

Four Reasons to Ship With Poly and Bubble Mailers

1. Mailer Envelopes Are Affordable

The most significant advantage to bubble and poly mailers is, of course, their affordability. While mailer boxes of a similar size can be as costly as $1.25 or more per unit, even when buying in bulk. Poly mailers, though, are usually only about $0.25 per unit when purchasing in bulk.

2. Mailers Save Space

Boxes, even when collapsed, take up a lot of space. Mailers, on the other hand, take up hardly any. When you get in the rush of packing and start laying out your packaging, recently assembled cardboard boxes can clutter your warehouse floor—sometimes even turning your work area into an annoying obstacle course. Poly mailers stack nicely and don’t require the assembly that boxes do. So you can pack more parcels more quickly.

3. Mailers Are Easy to Use

Some merchants may have a stigma around using something that seems so flimsy. Ultimately, poly mailers are just very economical and are quite commonplace. If you’ve ever ordered from Amazon or Walmart, you’ve likely received a mailer envelope. So, don’t worry about always delivering brown paper packages tied up with string, a few of your favorite things have already been delivered in poly mailers.

What to Ship in Poly Mailers

Durable, pliable items like teeshirts or beanies are perfect candidates for poly mailers. Anything that can be twisted, compacted, or absorb abuse without being damaged are perfect. Think of a poly mailer as more of a good surface to apply a shipping label. Again, this avoids additional handling surcharges or surface stains that could occur during transit. You also want to avoid shipping items that are too rigid in poly mailers. For instance, you wouldn’t want to ship a ninja throwing star in a poly mailer. It could rip the bag or hurt someone—probably both!

Ship Soft Items in Poly Mailers

While clothing makes a good item for shipping with poly mailers, not all clothes work. You wouldn’t want to ship a winter coat in a poly mailer, or even a pair of jeans. The best contents for poly mailers are usually under 1 lb. Lightweight materials like cotton or silk or wool work best.  

Where to Buy Poly Mailers

Poly mailers are easy to find. You can pick up a pack of them at drug stores or supermarkets like Walgreens or Walmart. But it’s more sensible to buy this item from somewhere. Buying in bulk not only ensures you have enough supplies in the event of an order surge, but it also offers better price breaks in volume.

How to Ship Bubble Mailers

Ship Denser Items in Bubble Mailers

Bubble mailers offer more cushioning than poly bags. As such, you can ship things like CDs or paperback books in them. Additionally, jewelry and some documents work better in bubble mailers than poly mailers or cardboard mailers. The added cushion makes creases less likely. However, you wouldn’t want to ship vinyl records or hardback books in a bubble mailer. They can still bend and this can cause you to lose a sale. It’s best to use more rigid cardboard boxes for these items. 

Is a Mailer an Envelope, Thick Envelope, or a Package? 

When you’re figuring out what package type to select with a mailer—whether its a poly bag, a bubble mailer, etc.—the options can sound very similar. The USPS classifies anything over 1/4 inch thick as a package. And the option “Thick envelope” is ultimately the same thing as a package. If you choose large envelope or another option for these package types, you can expect a billing adjustment to be charged to you or the recipient. When in doubt, provide the parcel dimensions and choose package/thick envelope. The carrier will return the correct shipping rate.
