Paper Boxes FAQs


Q:What materials are paper boxes made of?

A: All paper boxes or mailers are made of three-layer corrugated cardboard. The layers protect the items from any impact during transit. This material is also sustainable and recyclable. It comes in 1/16” E-Flute or 1/8” B-Flute thickness, depending on your indicated specs.

Q: Can I order branded paper boxes??

Yes, you can print branding elements like logos, your company name, contact details, and other visuals on your mailer box. Use our 3D online design tool to create it from scratch. The design tool has an intuitive menu where you can add and edit text, upload images, and combine colors on the different mailer box sections.

Q:How can I put my design on the custom boxes?

A: If you have a print-ready design, simply input the corresponding specs and request for a dieline template. You’ll receive a PDF file that shows the flat layout of your box, guiding where to place the design elements on the panels. For more information, check out this page .

Q: Should my artwork be in CMYK or RGB mode?

A: All artwork should be in CMYK mode to get the exact colors that you want on your printed product. RGB works better for web design and other applications that you view on your computer but for print products.

Q: What is the difference between the two white corrugated cardboard options?

A: The standard white corrugated cardboard is more popular because of its affordability. It comes in an uncoated finish that works for a design that doesn’t need extra shine or gloss on its surface.

Premium white corrugated cardboard has a smooth and bright white finish. It is recommended for luxury brands and special gift boxes that need to stand out at a glance.
