Sturdy and Stylish Corrugated Cardboard Options

Your custom mailer boxes will be printed on durable corrugated cardboard. It protects the items it carries in transit. Plus your customers can recycle the box after they’ve received your package. There are 2 thicknesses depending on the size of your box: the thinner 1/16” E-Flute and thicker 1/8” B-Flute.

We offer two colors that suit everything from a minimalist to a rustic design:

Standard White Corrugated Cardboard
  • Comes in a smooth, uncoated finish
  • Thick enough to withstand multiple handling and delivery

Premium White Corrugated Cardboard With Glossy Ink
  • Print your design in extra shiny, high-gloss UV and complement it with a radiant white background
  • Perfect for designs with vivid details and colors

Kraft (Brown) Corrugated Cardboard
  • The default look and finish of corrugated cardboard
  • Perfect for natural or rustic-themed designs or products such as organic items

Real Reviews from Real Customers

"I have been using NextDayFlyers for the past 8 years. The quality is excellent. What you submit is what you get. Even better still is the customer service. They will contact you if they see any questionable design flaws. I am not a professional designer, so I appreciate the extra care in them looking out for me."
