What Are Square Postal Tubes?
These mailing containers are a type of postal tube for documents or rolled items that have a square shape rather than the generic round one. They are constructed from sturdy, corrugated cardboard and are shipped flat for easy storage with the additional benefits of stability, stackability, and innovation. This prevents rolling and makes them highly crush-resistant and convenient for shipping artwork, posters, plans, and other long items.
Types
- Eco-friendly postal tubes
- Standard square mailing tubes
- Telescopic postal tubes
- Heavy-duty square mailing tubes
- Self-sealing tubes
Product Overview
Shape and Stability
The square design ensures the tubes don’t roll away on flat surfaces, are easy to store, and can be stacked, maximizing space and preventing damage.
Protection
Made from robust, corrugated cardboard, these tubes offer excellent protection against crushing and external conditions, ensuring goods arrive undamaged.
Branding
The flat surfaces allow for easy application of custom logos, graphics, and product information to improve your brand’s appearance and promote your brand.
Personalization
The main options for personalization are:
- Printing: You can go for custom printing or any ink, designs, and fonts.
- Stocks: Stock options available for your custom boxes generally include kraft cardboard, kraft rigid, and kraft corrugated.
- Finishes: The finishes available are Matte, Gloss, Aqueous, and Soft touch.
- Add-ons: Our add-ons include Embossing and debossing, Spot UV, Holography, and Foiling.

Artwork Preparation Guide
At BoxesGen, our Artwork Preparation Guide helps ensure your custom packaging design is print-ready for high-quality results. To get started, submit vector files (AI, EPS, or PDF) in CMYK color mode, with a 1/8 inch bleed and 300 DPI resolution. Convert all text to outlines and keep it at least 1/4 inch from the edges. Review your proof to ensure accuracy before submitting. Following these steps will guarantee your design is perfectly printed on your custom boxes.
Cut Line (Black Lines):
The cut line is the outline that marks where your custom packaging will be trimmed. It is typically represented by a solid black line in your artwork file.
Perforation (Dotted Black Lines):
Perforation lines, shown as dotted black lines, indicate where the box will have small, evenly spaced holes for easy tearing or separation. These are often used for tear-away sections.
Bleed Line (Green Lines):
The bleed line is the area extending beyond the cut line, usually marked with a green line in your artwork. Typically, a 1/8 inch (0.125") bleed is required to prevent any unwanted white borders.
Safety Margin (Dotted Green Lines):
The safety margin, marked by dotted green lines, is the area around the cut line where important elements (such as text, logos, or graphics) should be kept clear.
Crease Line (Red Lines)
The crease line, marked by red lines in your artwork, indicates where the box will be folded during production.
