Sample Box

PackM ensured our design was accurate and the colors were correct. The box was delivered within the specified time and was packaged inside a sturdy box (better than off the shelf or Amazon boxes). Thank you for the quick responses to our inquiries as well. Great product!

Combine Packaging and Branding With Custom Mailer Boxes 

Make your brand sing by sending products in custom boxes

Custom mailer boxes never fail to win over customers. That’s why you always see them in unboxing videos. They’re tailor-made to win people over.

There are perks to using customized boxes. For starters, you get to specify the box’s length, width, and height. If you’ve always used boxes that are either too big or small for your products, those days are over.

You also set which sides you want your box to get printed on. Print your design on the inside, outside, or both. If you don’t want us to print anything, you only need to tell us.

And don’t forget:

There are no minimum quantities. 

You can order as few or as many as you need. Just set the quantity to the exact number of boxes you want.

What Materials Are Available?

There are three types of box materials to choose from. 

Here’s a brief guide on materials to use for your box, as well as the factors to consider when choosing one.

Kraft is uncoated and unbleached. It’s the cheapest out of all the available options. When you think of a box, this material is what probably springs to mind. Its brown surface makes colors lighter or darker compared to what’s in your design file.

Standard White has a matte finish inside and out. It is the most popular material used for mailer boxes on our site.

Premium White delivers on its name by giving you the brightest coating of white on the interior and exterior of the box. Choose this if you want the best experience for your customers.
