Three Basic Types of seals for poly strapping and polyester strapping
The area where two ends of plastic strap are joined is called the seal joint. Generally, the strength at the joint of the strap is weaker than the break strength of the strapping itself. The joint efficiency is the percent of joint strength in relation to the straps break strength. For example, if the break strength of the strap is 500lbs and at the joint is 400lbs, the joint efficiency is 80% when using poly strapping tools with friction welds.
Strapping is joined by three methods; buckles, seals, and welds.
