  • Frequently Asked Questions

    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 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
    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: 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: 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: 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: 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: 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: How will my boxes be shipped?
    A:

     Your boxes will be shipped flat and unassembled.
