Folding Carton Types
In the world of packaging, the variety of folding paper boxes available can be overwhelming. Each type serves a unique purpose and offers specific benefits, making them suitable for various products and industries.
Reverse Tuck End
The Reverse Tuck End (RTE) box, much like the Straight Tuck End box, features flaps that tuck in opposite directions: one flap tucks from front to back, while the other tucks from back to front. This configuration enhances nesting efficiency in die-cutting and print layouts, making it ideal for automatic filling lines.

- Easy set up
- Compact storage (packed flat in cases)
- More affordable than STE due to better nesting capabilities
Ideal uses: This compact carton is suitable for a wide range of products, including pharmaceuticals, cosmetics, and small electronics.
Straight Tuck End
Straight Tuck End (STE) boxes are a popular choice for retail packaging. With both the top and bottom flaps tucking in the same direction, they offer a sleek and professional appearance. These boxes are simple to assemble, and their design keeps the front panel clear, making them perfect for displaying branding and product details.

This design ensures that contents stay protected during transit and storage. Additionally, cartons can be equipped with double-sided tape for hand-filling applications.

These boxes can be used as an inner tray and grouped with an outer sleeve, or even have a second glued double side wall that acts as a lid for even more protection. The double side walls can be glued for added stability. Additionally, the high-quality printing surface allows for attractive branding and product information display.
