Especially for strapping flat packages, the E-series with its sealless joint is suitable.
This closure was developed by TITAN and is especially appreciated because it is easier to implement, produces less material consumption, while providing a higher joint strength.
To connect the strap´s ends, however, it requires a level surface. In contrast to the usage of seals it does not cause reduction of the strap´s cross-section, so that it is everywhere the same. In this way even higher joint strengths can be realized than with the use of seals.
