Carton box stitching is a very important process in corrugated box manufacturing, especially for heavy-duty cartons, export boxes, and industrial packaging. Stitching provides stronger joint strength compared to gluing, making the box suitable for heavy load applications.
In the corrugated industry, carton boxes are stitched in different ways depending on box strength, load capacity, and box design.
1. Single Joint Stitching
Single joint stitching is the most commonly used stitching type in carton box manufacturing. In this type, only one side of the carton is stitched to join the box.
Suitable For:
- Regular Slotted Cartons (RSC)
- Light and medium weight cartons
- General packaging boxes
- Corrugated shipping cartons
Machines Used:
- Single Head Stitching Machine
- Double Head Stitching Machine
- Automatic Stitching Machine
2. Single Cum Double Joint Stitching
Single cum double joint stitching is used for heavy-duty cartons where extra joint strength is required. In this type, one side of the carton is stitched with a single stitch and the other side is stitched with a double stitch.
Suitable For:
- Heavy weight cartons
- Export cartons
- Industrial product packaging
- Large size cartons
Machines Used:
- Single Cum Double Stitching Machine
- Double Head Stitching Machine
- Fully Automatic Stitching Machine
3. Double Joint Stitching
Double joint stitching is used when very high joint strength is required. In this type, both sides of the carton are stitched, making the box very strong and suitable for heavy products.
Suitable For:
- Very heavy load cartons
- Automobile parts packaging
- Machinery packaging
- Export packaging
- Double wall and triple wall cartons
Machines Used:
- Double Head Stitching Machine
- Jumbo Size Stitching Machine
- Fully Automatic Stitching Machine
