Is it normal that it takes some effort to unroll TapeShaper™ from the roll?
Yes, this tension is by design and required to keep the product taut. Always start by SLOWLY unrolling TapeShaper™ a few inches off the roll, making sure not to have it stick upon itself. Also, some of the tape towards the end of the roll may appear too sticky to remove from the core and hence not useable. This is normal and has been accounted for in the average application quantity. This characteristic does not constitute a defective roll, it is normal.
