Top FAQs Explore all FAQs
- What happens after I place my order? Do I get a proof before printing?
  
  After checkout, our dedicated Prepress team will review your design for any technical concerns and send a 2D digital proof of your custom boxes to your email within 24 hours. If any changes need to be made, you can send a note directly to our Prepress team through the proof page and they'll be happy to help with finalizing your design for printing.
- How do I know if my art is printable?
  
  Our dedicated in-house Prepress team will review your custom box design for any technical concerns (artwork resolution, blurriness, splits, thin lines, and bleeds) and if found, will note them for your attention in the proof. If you're unsure of how to fix any printing concerns that are noted, our Prepress representatives are happy to help you through the process. It's important to keep in mind that our team does not check for spelling or grammar errors, nor do they provide any subjective feedback on design content.
- What is the turnaround time on my order?
  
  Our Standard turnaround for most custom packaging orders is around 10 business days and Rush turnaround is 7 business days. These turnarounds do not include transit time (1 - 7 business days depending on your location). Special custom or bulk orders may require a few extra days to get setup and produced. Please note that during extremely busy times of year some orders may take longer to complete. While delivery estimates cannot be guaranteed, all dates shown at checkout are the quickest estimate we offer. If your delivery date is time sensitive, we highly recommend choosing Rush production and expedited shipping for your box orders.
- Can I get an instant quote for my order?
  
  Yes, you can select your size, material, and quantity on our free 3D design tool to instantly view a quote for your project. As you upload artwork, add text, or color the background in each panel of the 3D model, you'll see your Unit Price update in real-time.
- Can you print inside the boxes?
  
  Yes! We can print on the inside of any of our corrugated box styles. This includes Mailers, Shipping Boxes, and Tuck Tops (our secret menu product!). Product Boxes are currently limited to printing on the exterior only. You can even use our online box designer to design the inside of your custom boxes. For Shippers and Tuck Tops, we currently require a 2D dieline template be submitted for both the interior and exterior so we can set up your order as a custom order. You can also submit designs this way for our Mailer boxes, if you prefer to build on a 2D Illustrator template instead of our free 3D box design tool.
- How to get a dieline?
  
  If you prefer to work in 2D to create your design in Adobe Illustrator (or another tool outside of our website), we recommend using a dieline template. For corrugated and cardstock boxes, you can download a free template from the artwork upload page or within our online design studio. For our other products, dielines are available for download from the template section of the product detail page.

How do you assemble a Mailer Box?

How do you assemble a Mailer Box?

Are you unsure of how to assemble your corrugated mailer boxes, or want to make sure you're doing it right? Watch this video–it helps!

How to assemble a Mailer Box from Packlane on YouTube.

Prefer step-by-step instructions? These should help you get a great result:

1) Clear off a clean, flat work surface. Ideally, the surface should be larger than your un-assembled box sheet, so the sheet can sit flat and you're not bumping into other objects as you build the box. For best results, do not layer the boxes while folding, as this can damage the boxes underneath and result in poor creases in the box you're working on.

2) Look for the scores (pre-fold lines) on the interior side of your unassembled box. One by one, fold each score completely inward, then release it to lie flat on the table, interior facing up. This is called creasing, or "pre-breaking" the scores; it ensures that the actual folds will be sharp.

Please note: On the side flaps, two scores are very close together. You must take care to fold each crease separately. Otherwise, the side panel will seem too short on the inside, and the sidewall will not lock into the bottom.

3) Fold up the front and back flaps, positioning the tuck flaps along the side of the box as much as possible. Lightly brace the back in place as you complete the next step.

4) Bring up the sides of your box by folding the left and right side flaps up and over the hidden flaps. You can do this on both sides at once, or each side individually.

Then snap each side panel into the holes in the bottom of the box, continuing the same motion. This ensures a very symmetrical, even structure where the sides are equally snug.

The key to knowing it's right is that the tops of the side walls are flat, not slanted or peaked.

5) You can now add your contents, close the lid, and slide the locking tabs into the slots in the sidewall. The result should be a sturdy, locked box.

If something feels off or the box isn't closing smoothly, please reach out to us, and we'll be happy to help troubleshoot!
