Shrink wrap heat guns are necessary during the shrink wrapping process. Wherever the shrink wrap is overlapped and heat is applied it will weld back to itself we call this “self-welding material”. Options such as the Shrinkfast models 998 and 975 are the most widely used and popular. We also offer extensions for each heat gun available in multiple lengths. Extensions provide added reach needed when shrinking something high or wide. They are also a safer alternative to climbing ladders.
