  • Frequently Asked Questions

    Q: How can I get a dieline template?
    A:

    After completing your order, we’ll send you the dieline template file through your given email address.

    Q: How can I create my design?
    A:

    We have an Online Design Studio that makes it super easy to add logo, text, and graphics to your box within minutes. You can also use a professional desktop application like Adobe Illustrator® and send us the completed artwork. Already have a file but have questions about your design? Email our packaging experts at artwork@packola.com for a review.

    Q: Can I buy a single mailer box?
    A:

    Yes, you can order one (1) mailer box. We have no minimum quantity order. You can order as few or as many as you need.

    Q: What is the difference between shipping boxes and mailer boxes?
    A:

    Shipping boxes are larger and used for bulky items, while mailer boxes are smaller and designed for individual or small items. Mailer boxes are ideal for e-commerce and don’t require adhesives for assembly.

    Q: How will my boxes be shipped?
    A:

    Your boxes will be shipped flat and unassembled.

    Q: Can I ship a mailer box without using any other external packaging?
    A:

    Yes, you can. The corrugated cardboard is strong enough to withstand the rigors of shipping. However, we recommend using external packaging such as a shipping box to provide a better unboxing experience.

    Q: Why did you print a QR code on my custom boxes?
    A:

    The QR code makes it easier for us to track your orders while it’s in production. This means we get to finish it faster so you can receive it as early as possible. It won’t affect the overall look of your custom box since it’s printed on a hidden area.

    Q: Can I order a box type other than mailers, shippers, and product boxes?
    A:

    Want a specific box type you don’t see on our website? Contact us at info@packola.com or 1-855-PACKOLA so our customer service team can help you.

    Q: Is a mailer box easy to assemble?
    A:

    Yes. The mailer box ships flat and pre-scored. Follow the steps in the video to quickly assemble your custom box:

    Q: How do I know what box size I need?
    A:

    Packola measures the interior dimensions for box production, meaning the sizes you input are the measurements inside the box when it is folded. You can follow these steps to help gauge the box measurements you need:

    Lay out and organize all the items you plan to put inside your box on a flat surface.

    Stack them as you would when packing the box.

               - Include any decorative packaging material, such as bubble wrap or packaging foam.

    Measure the dimensions accordingly in inches

               - The length should be the left-to-right dimension

               - The width is the front-to-back dimension

               - The depth/height is from the flat surface to the top of the tallest item

    Add a 0.25" margin to each dimension to ensure easy packaging

    Q: How much weight can your corrugated boxes support?
    A:

    Our corrugated boxes have a 32 ECT rating. Boxes with 32 ECT rating usually support the following weights:

    E-flute: up to ~20-25 lbs

    B-flute: up to ~30-40 lbs

    Best Shipping Box Ever September 17, 2025 by Doc Jung ( TX )
    “My shipping boxes for my books came out perfectly with just a few minor flaws. I have already shipped some books and with the addition of some matching tissue paper, my customers were amazed and happy receiving their book in such a stylish box, they all said that they will keep the box and use it for something so they will always have my webpage available. Great Job Packola.com”

    Scorched box cuts and incomplete cuts September 16, 2025 by Carol R ( CA )
    “Cuts were done poorly this time. I have placed swveral orders over parlay few years for white boxes. This batch, the cutting device must have been too hot as there are scorch marks on the boxes. And I have several where the cut is incomplete. Hope for better next time.”
    Response from Packola.com:

    Thank you for taking the time to leave a review, we truly appreciate it! We'd like the opportunity to look into this issue further.
