Custom Boxes & Padded Mailers FAQs | FedEx Office

Can I upload my own design?

Yes. Simply download our template and apply your own design using Adobe Illustrator, Adobe Photoshop or CorelDRAW.

For more information, please visit Ecobag.

What color settings should I use?

You can upload artwork in either CMYK or RGB, but we recommend converting images to CMYK before uploading. Please be aware that colors on RGB artwork may appear duller or lack contrast when printed.

What is the recommended DPI for uploading my own image?

A minimum of 300 DPI is recommended for images. Anything less than this may result in pixelation.

Does the number of colors used affected the price?

No. The price you see is the correct price, so feel free to use as many colors as necessary.

Can I save my work and come back to it later?

Yes. Create an account to take advantage of unlimited design storage, revisit templates, and even reorder previous boxes and padded mailers.

How can I see what my finished box will look like?

Click on the 3D Preview button to see your design from every angle. Want a finished sample? You can also order just one box of any size and style with your design.

The preview looks blurry. Will it print that way?

No. The preview only shows how the graphics align on the box. The final print is much sharper, as long as vector or high-resolution graphics are used. You will be contacted if your graphics appear to be at too low a resolution.

Does FedEx Office have any printing standards relating to what content I can print?

Yes. Our custom branded boxes and padded mailer printing standards outline what content is and is not allowed to be printed on the packaging. The goal of these printing standards is to encourage expression and create a safe environment.

Printing Standards: We do not accept artwork or text portraying nudity, sexual activity, violence, criminal activity, terrorist propaganda, or hate speech of any nature. We define hate speech as a direct attack on people based on race, national origin, gender, ethnicity, religious affiliation, sexual orientation, or disability. We are also committed to banning content that encourages real-world harm, including physical, financial, and emotional injury. We also take intellectual property rights seriously and believe they are important to promoting creativity and expression. You must respect existing copyrights, trademarks, and other legal rights. Any submitted artwork that is in violation of our printing standards will be rejected.

Am I limited to printing only on the outside of the box?

Not at all! Most corrugated box styles allow for inside printing.

If this option is available for your box, simply select 2-Sided when choosing your box dimensions. From there, you can design both the inside and outside using our online tools or by uploading your own graphics.

Can I print boxes with a glossy finish?

Yes. If you want to enhance the look of your box, choose Premium White Paper with a semi-gloss finish. Semi-gloss finish is not available on our Kraft or Standard White boxes.

What are the different box materials and finishes?

  • Standard White is the typical corrugated material used for packaging. It has slight variations in the white color.
  • Premium White adds a look of luxury to your box and is available in both matte and semi-gloss finishes. Semi-gloss finish is a process in which ink is cured to appear glossier than a traditional matte finish. It is only available in Premium White.
  • Kraft is the standard brown material you typically see on boxes. Once you add your colors and logo, your custom branded boxes will stand out. Be sure to think about the colors you use when choosing this material. Colors will look darker on Kraft than colors printed on Standard or Premium White.

Does FedEx Office have guidelines for laying out my box design?

Yes. To ensure the best quality, do not rotate or alter the structural template (CAD Die Line). Ensure to include this die line in your print file because it contains Spot Colors for the cut and crease lines. These colors tell our machines how to convert your box. Do not change these lines to CMYK colors, or they will print on the final product. Conversely, do not use structural "colors" in your printed design because when the die line is removed from printing, everything that is a structural code, like "cut" and "crease," will be removed as well.

What font and type are recommended for boxes?

We recommend that you use 12 point or larger font with a heavier weight for text that is reversed out. All type should be outlined in your final artwork file. Avoid specifying small trademark and register mark symbols to print in reverse, as they may fill in when printed.

Should I include bleed on my box artwork file?

Yes. All final artwork files should maintain a minimum bleed of .125" (1/8") on all edges and into the glue flap.

Can I include a UPC or barcode in my box design?

Yes. Any UPC-A type barcodes need to be at least 150% size (approximately 2.2" wide). We recommend all barcodes to be at least .5" tall.

What should my image resolution be?

For best results, all artwork and image resolution should be no less than 300 DPI.

Do you have any design best practices or tips I should keep in mind for boxes?

Graphics and text designs (i.e., non-photographic content) are best submitted as either vector-based PDFs or Adobe Illustrator (.ai) files. This ensures lines and text are crisp. Please ensure there are no cut or crop lines, all transparencies have been flattened, and all fonts are embedded (or outlined) before saving your designs.

When using text or line art:

  • Make sure the text is at least 12 point — smaller text can look good on-screen but will not print well.
  • Try to keep text in bold colors made up of one or two inks only (C, M, Y, or K).
  • Artwork registration to any panel may vary up to 1/8".
  • Include at least a .25" bleed in areas where graphics extend past the die line.
  • When printing lines in a solid or dark color, they should be no thinner than 1 point.
  • Make sure all fonts are embedded or outlined.
  • If using Illustrator, save it as a PDF using the Adobe PDF Preset "Illustrator Default"

Is FedEx Office® local delivery available at all FedEx Office locations?

No, it’s available at select locations to destinations within a 30-mile radius. Orders with special instructions cannot be delivered via this service.

How do I track my order?

Where is my order number?

When you place a FedEx Office® Marketplace order, you receive a confirmation . This contains your unique order number, called a GTN.

What sizes do you offer in the recyclable padded mailer?

Our mailer sizes reflect those commonly found in e-commerce mailings with the following outside dimensions:

  • Size 0 – 7” x 10” 
  • Size 2 – 10” x 12”
  • Size 5 – 12” x 15”
  • Size 6 – 14” x 18”

Do you offer custom sizes in padded mailers?

We offer four great sizes but cannot customize sizing at this time. 

Can I print edge to edge on the padded mailer?

For the recyclable padded mailer, we require printing with an offset interior bleed of at least 1" from the edges.

Is it possible to print on both sides of the recyclable padded mailer?

At this time, we do not offer print on both sides.

Can the print on the padded mailer template be removed or changed?

There are three areas that come pre-printed and cannot be removed or changed. This includes the How2Recycle® Paper Bag label, the “Tear Here to Open” wording at the tear strip and the mailer size number with the text.

Can I print past the folded tear area?

The tear area is thinner than the rest of the padded mailer, so to avoid blurry text, we do not print on it.

How small can the text be on the padded mailer? 


Gusseted Poly Bags at Wholesale Prices | Elements Supply

We recommend you size your printed text at no less than 6pt, but it can go as small as 4pt. Knocked out text should be at least 8pt but can go down to 6 pt. Our recommendations ensure all text stays sharp and easy to read. 

How thin can printed lines be?

For printed lines please do not go thinner than 0.125 pt. For knocked out lines, they shouldn’t be thinner than 0.75 pt. 

Can I print a barcode on the recyclable padded mailers?

We can print a UPC code with a minimum 1.25” width. The orientation of the barcode needs to be vertical from the bottom up to the tear strip.

The padded mailer is printed using water-based ink, which meets health and environmental requirements throughout the entire life cycle of a print, from production to disposal. 

Can I use white ink?

Unfortunately, we do not offer white ink. 

What does the How2Recycle® label mean?

The padded mailer carries the How2Recylce mark, meaning that it is widely accepted in curbside recycling programs and can be placed in the same bin as paper and boxes. Sorting equipment will recognize the mailer as paper and sort it into appropriate recycling bales. 

What is the inside material used in recyclable padded mailer?

The mailer is made up of a layer of padding sandwiched between sheets of lightweight paper. The compostable padding is created with components commonly found in the glue used to make corrugated boxes. It was designed to easily separate from the paper the same way print inks are removed during the paper recycling process. 

Is the padded mailer waterproof?

While it does hold up well when wet, since the padded mailer doesn’t have a plastic coating, it is not waterproof. We recommend protecting items if they are easily damaged by water. 

Will I see a proof when I place my order?
