Query: What a WASTE

This kind of privacy film works very well. This particular brand of film works very well. The challenge is in getting the film off the backing paper.Once the backing paper splits and tears along the edge where you're trying to seperate it from the film, there is NO peeling it away from the film. If you try, the film itself will tear along with the backing paper.I did get the job done with the materials at hand, but...I WASTED MORE THAN 50% OF THIS FILM BECAUSE THE BACKING PAPER WOULD NOT PEEL AWAY FROM THE FILM WITHOUT TEARING.50% waste (at least) "built in" to the product makes it cost double the price.
