  • 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

    IN LOVE!!!! November 21, 2025 by Tonya A Geese ( SC )
    “These new boxes are everything I hoped for and a little bit smug about it. The quality is sturdy enough to make my pastes feel like they’re riding first class, the design is clean and professional, and the unboxing experience finally matches the level of love I put into every jar. No crushed corners, no flimsy cardboard, no “please survive this trip” prayers. They’re the perfect size, the branding looks incredible on them, and they make every order feel like a tiny colorful present headed straight to your door. Honestly? Game changer for the studio. If you’re a maker or small business owner looking for packaging that feels elevated without being fussy, these boxes are the vibe. Love them.”

    “The blank demo box was nice, but we couldnt tell how crisp the printing would be based on your website. I asked about seeing some printed samples but was told thats not possible and I would have to order a printed box to see. We went with another printer as they were able to provide printed samples and pictures so we can see the quality of the print before commiting. The sample didnt need to be my artwork, but just an example that my team could physically see. Even a picture would have been helpful. Ultimately this is why we went with a different vendor.”
