What type of seal should be used with polypropylene straps?
Choice of seal is largely determined by the type of tool being used and/or the application. As a general guide semi open standard smooth faced seals should only be used on very light packages as their ability to stop straps slipping through under load are limited. Heavy duty smooth faced seals (32mm long x 0.6mm) such as the SO12HD are recommended for most applications. Some tools use serrated seals and these are suitable for most applications although caution should be exercised as inferior copies are appearing on the UK market..
