Packaging & Printing
eCommerce is about cutting costs, and the type of packaging you use will determine how much you will pay to get items to the customer's doorstep. To get a positive return on their customer acquisition cost, retailers need to drive shipping costs down.

One way to do this is to choose the right packaging for shipments that will protect items from getting damaged on transit at a reasonable cost. While cardboard boxes are excellent for mailing delicate items, they may be unnecessary and expensive when sending less fragile items such as apparel and shoes.
That is why poly mailers have gained much popularity in the eCommerce shipping industry as an affordable alternative to standard packaging. They enable eCommerce merchants to strike the delicate balance between keeping buyers items safe and reducing shipping costs.
In this article, we define what poly mailers are, the common reason retailers use them, the type of product they can ship, and where to get them. We will also look at some of the shipping solutions that Easyship offers to eCommerce retailers to help them drive down shipping costs further.
Poly mailers are lightweight, sturdy plastic bags that are designed to ship light and less fragile items. They are a great alternative to standard packaging. They help eCommerce sellers cut back on packaging and shipping costs because they are affordable and take up less space on carriers' vehicles while on transit.
They have a self-sealing fold-over lip and require no tape. A shipping label can also be affixed directly to the bag. This makes them easier to pack and ship, hence making for an excellent alternative for shipping non-fragile items that don't have to be shipped in big bulky boxes.
Whether you want to add more protection to your buyer's items, lower shipping costs, be eco-friendly or showcase your brand, you are sure to get the exact type of poly mailer to achieve your goals.
Basically, there are four types of poly mailers available. They are:

As we have already seen, poly mailers provide an affordable alternative to standard packaging. Here are the common reasons why online sellers use poly mailers.
So, what eCommerce products are ideal for shipping with poly mailers? Well, poly mailers are perfect for shipping non-fragile items that cannot be crushed, or items that are already in sturdy packaging. Apparel and shoes are good examples in these categories.
If a product won't get damaged if thrown about or heavy boxes are tossed on top of it, then it can be shipped in a poly mailer bag.
However, you should avoid using poly mailers on fragile items made of glass, or any other items such as foods that can be smashed and crumbled. It is safe to stick with boxes when mailing such items. If you want to ship such products in a poly mailer bag, first ensure that they are in sturdy packaging before you wrap them with a poly mailer bag.
Top categories of items that you can ship with poly mailers include:
So far, you know what poly mailers are and the type of products you can ship with poly mailer bags. But where can you buy them? You can find poly mailers for purchase at any of the major carriers' retail locations or online, and any other store that sells shipping supplies.
Common places include:
It is important that you find the right poly mailer that makes for a snug fit for the item you are sending. For example, an extra small t-shirt will need a different poly mailer size than an XXL t-shirt. The table below gives you a ballpark of common poly mailer sizes and the products that are best suited for them.
While standard packaging such as cardboard boxes is ideal for shipping certain products, it may be unnecessary sometimes. For example, it won't make sense to put a product that is already packaged in a sturdy box inside another cardboard box.
Remember that carriers use both the actual weight and dimensional weight -whichever is greater to calculate the shipping rate of your package.
Take for example a pair of shoes, that is already packaged in a strong cardboard box. Putting it inside another cardboard box adds both the actual weight and the dimensional weight of the package. This increases the shipping rate.
If you ship your pair of shoes inside a poly mailer bag, you are not only reducing the actual weight of the package, but also the dimensional weight. That means you will significantly save on shipping costs.
Therefore, it is advisable that you use poly mailers to ship products that are already in sturdy packaging, and any other items that cannot easily be crushed or broken, and only use boxes to mail fragile items that are susceptible to damage if sent without a box.
Poly mailers are a great option when it comes to saving on shipping costs because they are lightweight and occupy less space on delivery trucks. To make sure that your buyers receive their packages in pristine condition, there are some things you need to consider for your shipping process with poly mailers.
Here is a quick rundown:
Poly mailers are commonly shipped with USPS. To that end, there are some USPS rules and guidelines that you should be aware of when shipping poly mailers.

Poly mailers are an excellent option when shipping products that are already in steady packaging or non-fragile items that cannot be easily crushed or broken. They provide an affordable option to standard packaging, hence helping eCommerce sellers save on packaging and shipping costs.

Poly mailers are those nifty plastic envelopes you see everywhere. They’re lightweight, durable, and perfect for shipping a variety of items. But here’s a question I get asked a lot: is a poly mailer considered an envelope? Technically, it’s a special kind of envelope—water-resistant, tear-proof, and way cooler looking, especially if you opt for a color poly mailer.
I remember the first time I used a poly mailer. I was shipping a hand-knitted scarf to a customer, and I was worried about it getting wet. The poly mailer was a lifesaver! Not a drop of moisture got in, and my customer was thrilled.
When it comes to shipping, one size doesn’t fit all. Just as you wouldn’t wear shoes that are too tight or too loose, you shouldn’t ship products in ill-fitting mailers.

These are the giants of the poly mailer world, ideal for clothing items, bulk orders, or even those fluffy teddy bears.
While size is crucial, appearance matters too. Enter the color poly mailer. These aren’t just about aesthetics. A colored mailer can be a branding opportunity. Imagine your customer’s excitement when they spot your signature-colored package in their mail pile. It’s like sending a little rainbow with every shipment!
Ever tried shipping a yoga mat or a set of blueprints? Traditional boxes or envelopes won’t cut it. That’s where long poly mailers come into play. They’re designed to accommodate items that are long without being bulky. On the flip side, for those smaller, more frequent shipments, the 6 x 9 poly mailers are a staple in any shipper’s arsenal.
Whether you’re a small business owner shipping handmade crafts or a large enterprise dispatching thousands of products daily, there’s a poly mailer out there for you.

Before you even think about buying poly mailers, grab a measuring tape. Measure your product’s length, width, and height. But don’t stop there!
Remember, it’s not just about fitting the product; it’s about ensuring it arrives in pristine condition. So, always account for:
I’ll share a little story. I once tried to squeeze a bulky sweater into a mailer that was too small. Not only did it look like the mailer had swallowed a football, but it also tore at the seams during transit. The lesson? Never overstuff your poly mailer. It’s not worth the heartbreak (or the refund).
Your product shouldn’t swim in the mailer, nor should it feel choked. Aim for the “just right” fit. If you’re in doubt, always size up. A priority mail poly mailer can be a great choice for those special shipments that need a bit more care.
Have you ever questioned, how to ship a poly mailer? Well, let me give you some tips. Once you’ve got the sizing down, the next step is to ship your product. And trust me, it’s as easy as pie.
Now, here’s a quirky query I’ve encountered: Can you ship a box in a poly mailer? The answer is a resounding yes! It’s perfect for adding an extra layer of protection or for discreet shipping. Just ensure the box fits snugly without straining the mailer.
If you’re shipping in volume, consider buying wholesale poly mailer bags. It’s cost-effective and ensures you always have the right size on hand.
I once ran out of mailers during the holiday rush. It was a nightmare. Now, I always stock up with wholesale options, and I never have to worry.
Picking the perfect poly mailer size? It’s not rocket science! With a pinch of know-how and some handy tools, you’ll be shipping like a pro in no time.
