Frequently Asked Questions

Q: How do I start creating custom mailer boxes?

A: Initiating the process for your personalized mailer box is quite straightforward. Navigate to the product page and clock the 'Customize' button. You can design your artwork directly using the 3D Design Studio or upload your own design. Once you've finalized your order at checkout, we'll commence production of your custom order.

Q: What are the standard sizes and dimensions for mailer boxes?

A: Ucanpack has hundreds of stock mailer box sizes. If you need a custom size that is not available online, we can quickly make any custom corrugated box, fitment, display, etc. with custom printing. Call us 201.975.6272 to get started!

Q: Can I buy a single mailer box?

A: Yes, you can order a sample mailer box.

Q: Are mailer boxes easy to assemble?

A: Indeed, setting up a mailer box is straightforward. The box arrives flat and pre-scored for easy assembly. Just follow these steps to prepare your custom box:

  • Bend the pre-scored lines inward.
  • Lift up the front and back flaps.
  • Raise the box's side walls, tuck them inside, and ensure they click into place.
  • The mailer box is assembled and ready for use.

Q: How will my boxes be shipped?

A: Ucanpack ships all boxes flat and unassembled.

Q: When will I receive my mailers?

A: Our usual production timeline is within 2-3 business days. If you need an expedited service, we can complete production in 1-2 business days. Similarly, creating a sample also takes 1-2 business days. Please note that this schedule excludes holidays, weekends, and shipping time.

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

A: Our kraft corrugated cardboard, which has a specification of 200lbs / 32ECT, is durable enough to endure handling during shipping. However, for specialized needs like custom-printed boxes or high-end white mailers, we advise supplementing with an external shipping box to enhance the unboxing experience.

Q: What will the finish of the mailer boxes look like?

A: The final look of your boxes hinges on the type of material you pick. Both Kraft and the standard white materials have an uncoated, matte finish. Opting for premium white gives a gentle shine to the surface. On the other hand, selecting the glossy ink choice will provide a brighter luster due to the high-gloss UV ink that's used.

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

A: Absolutely. We are a manufacturer with house die cutting and printing infrastructure. We can quickly make any custom corrugated box, fitment, display, etc. with custom printing. Call us 201.975.6272 to get started

Q: Can I print on the inside and outside of the box?

A: Yes, you can. Select add 'Inside Print' on the design module and double click on each box face to upload graphics and logos.

Q: How can I get a dieline template?

A: You do NOT need to place an order before requesting a dieline template. Just email us or call us at 201.975.6272 and we'd be happy to send you the dieline free of cost!
