How Can I Ship Using Poly Mailers at UPS?

The most important step to shipping anything with a poly mailer is to ensure that you have the right poly mailer for the job.

Cheap poly mailers can rip while your package is in transit, which means the contents of your package can be lost or damaged.

Therefore, be sure to choose a sturdy mailer.

It can be worth the extra expenditure to opt for a bubble or padded poly mailer, which offers an extra layer of protection for your shipment.

Be sure that you’ve chosen the right size poly mailer- you want the contents of your package to take up almost the whole mailer, leaving very little wiggle room and overhang, which eliminates the potential for snags.

If your poly mailer seems a little too big for whatever you’re trying to ship, you can always use padding such as newspaper or packing peanuts to help fill up some of the extra space.

Once your shipment is safely packaged into your chosen poly mailer, simply create your UPS label and securely attach it to your package, making sure there are no wrinkles or creases and that all information is visible and legible.

Next, set a time for your package to be picked up or drop it off at one of the approved UPS drop-box locations, which can be found here, and you’re done!

UPS accepts items shipped in poly mailers as long as the item’s label is securely attached, visible, and legible.

Poly mailers can significantly reduce your shipping costs since they’re lighter and smaller in size than traditional packaging.

As well, they’re available for free through the UPS website if you have a UPS My Choice account.

To ship with a poly mailer, it’s most important to ensure you have the right poly mailer for what you want to ship, and that you can fit the shipping label on it securely.
