The Folding Carton Handbook: Sttark's Guide to Carton Setup

Folding carton packaging plays a crucial role in capturing consumer attention and influencing purchasing decisions in a competitive retail space. Folding cartons, with their versatility, functionality, and visual appeal, have emerged as a preferred packaging solution for a wide range of products, from food and beverages to electronics and cosmetics.

To create an effective folding carton design, you must carefully consider both practical and aesthetic aspects. Our comprehensive guide to setting up a folding carton will walk you through the process of designing and creating folding carton packaging.

Determining Folding Carton Packaging Requirements

The first step in designing a folding carton is to define the packaging requirements clearly. This involves understanding the product’s dimensions, weight, and any special handling or storage needs. Consider factors such as product fragility, temperature sensitivity, and desired stacking capabilities.

Front, Back, and Side Panels

Folding cartons typically feature six panels: one front panel, one back panel, two side panels, a top flap, and a bottom. Each panel serves a specific purpose in functionality, communicating product information, branding elements, and promotional messages.

Front Panel: The front panels are the most prominent and play a critical role in capturing attention and conveying key product information. Use high-quality graphics, clear product descriptions, and compelling calls to action.

Back Panel: The back panels provide additional space for product details, nutritional information, and legal requirements. Use a clear and concise layout to ensure easy readability.

Side Panels: The side panels offer valuable real estate for extending brand messaging, showcasing product features, and displaying graphics or illustrations. Utilize this space strategically to reinforce the brand identity and enhance visual appeal.

Different Folding Carton Styles

Auto-Lock Boxes

Auto-lock bottom cartons, also known as crash-lock or automatic bottom cartons, feature a pre-formed bottom that automatically opens when the carton is erected. This self-locking mechanism eliminates the need for glue or tape, making them ideal for high-speed packaging applications. Auto-Lock cartons are known for their sturdiness and ability to support heavier products. They are commonly used for packaging bottles, cans, and other rigid items.

Straight Tuck End Boxes

Straight tuck end cartons are characterized by their simple design with tuck closures on both ends of the carton. The top and bottom closure panels fold in the same direction, creating a clean and streamlined appearance. Straight Tuck cartons are versatile and suitable for a wide range of products, from lightweight items like cosmetics to medium-weight products like food and beverages. Their ease of assembly makes them a popular choice for both manual and automatic packaging products.

Custom Carton Styles

In addition to the standard styles mentioned above (available to create and download on, brands can use numerous custom folding carton styles to meet specific product requirements or branding goals. Custom template sites like Die Cut. Templates offer a variety of options for customizing carton styles, including Reverse Tuck, Five-Panel Folders, Tray and Lid, Mailer Lock, Separators, Polygonal Boxes, and Angled Boxes.  Be sure to confirm size and capability restrictions with your printer before committing to a custom-style carton template.

Measuring Carton Size

Once you determine the packaging requirements, it’s time to determine the appropriate carton size. This involves measuring the product’s dimensions and adding sufficient space for packaging materials and product movement. Ensure that the carton dimensions are compatible with standard product sizes and shipping regulations.

Ensure that the dimensions of your carton box are large enough to accommodate the product comfortably, leaving some space for any packaging materials and product movement. Account for slight variations in the cutting and finishing process. Allow for some wiggle room in the dimensions to avoid issues with product fitting or assembly. The best way to find the right box size for your product is to measure your product at its longest, widest, and highest points. 

Record and calculate those dimensions as length x width x depth to get the volume of the box in cubic units. By carefully measuring carton dimensions and considering these factors, you can ensure that your products are packaged securely, efficiently, and in compliance with industry standards.

Download and Test Folding Carton Dimensions

Sttark provides a convenient online platform for downloading and customizing folding carton templates. From the options provided, simply select the desired carton style and dimensions.

Length: The measurement across the front of your product.

Width: The measurement of the side of your product.

Depth: The height of your product when placed upright.

One thing you need to note is that the dimensions for the side panels need to be less than or equal to the length of your cartons. Here’s a visual to help you understand the length, width, and depth of your product box:

Folding Carton Dielines

Once you have determined the style, size, and dimensions of your desired folding carton, you will be provided with a dieline to create your artwork and design file. If you create your dieline template on, you can download a vector SVG file of your dieline. You will need to create your carton artwork with all panels to fit in your carton dieline template.

Accepted Design Formats for Submission

Adobe Illustrator is the preferred method for creating and adjusting carton designs.  Adobe Photoshop and JPG files are acceptable, but flattened, non-vector designs make simple editing for printing purposes very difficult. When available, always submit your artwork in fully vector format, with all fonts outlined and all images embedded. If you don’t want to invest in vector graphics programs, you can hire a packaging designer to help you create your folding carton artwork.

Bleed, Safe Zones & Glue Flaps

Crucial aspects of folding carton design and mechanics are the bleed, safe zones, and glue flaps. Understanding these elements ensures that the printed artwork extends beyond the trim edge and that important elements are not cut off or creased on edges during the finishing process.


Bleed refers to the area of the artwork that extends beyond the trim edge of the carton. This extra margin is necessary to account for slight variations in the cutting and folding process. The extra margin ensures that there are no white or unprinted edges when the manufacturer trims the carton to final size. Typically, a bleed of 0.125 inches (3.175mm) is recommended for folding cartons.

Artwork Safe Zones

Safe zones, on the other hand, define the area within the carton where important text, logos, or graphics should be placed to avoid being cut off along the edges during trimming or folding. You should set your safe zones at 0.25 inches (6.35mm) from the dieline edge.

Glue Flaps

Glue flaps are essential for securing the carton’s structure. Avoid placing artwork on glue flaps or bottom folds, as these areas may not be visible after assembly.

Adhering to bleed and safe zone guidelines provides the following benefits to you:

  • Prevents unfinished edges from appearing on the finished carton
  • Protects important text, logos, and graphics from being cut off
  • Creates a more polished and professional appearance

Remember, a well-designed folding carton can be a powerful tool for differentiating your products and establishing a lasting impression on consumers.

  3. Design for Impact: Folding cartons are a prime opportunity to showcase your brand and influence purchasing decisions. Utilize high-quality graphics, clear communication, and strategic use of space to capture attention and drive sales.
