| TYPES OF JOINTS | ||
|---|---|---|
 |
 |
 |
| Stitch Joint | Tape Joint | Glue Joint |
STITCH JOINT
The strongest available joint. It uses large industrial staples and is generally reserved for the heaviest or most abused packages. The stitch flap can be placed either on the inside or outside of the carton.
TAPE JOINT
Taped boxes have no additional flap, instead the two ends of the box blank butt up against one another and then tape is applied. This joint is about as strong as glue but is used when the additional flap is unwanted on either the inside or outside of the box.
GLUE JOINT
This joint uses a liquid adhesive to bond the glue flap to the other side of the box. It is the most common joint and is appropriate for most applications. As with stitch, the glue flap can be placed either on the inside or the outside of the carton.
