I do not know what you have changed about your force flex bags, but I have bought store brands better than this. I was very satisfied with the bags prior to purchasing the box I have now. I think I may have to just throw the whole box away. I can not pull them from the can without them falling to pieces, or carrying them to the curb I have the same problem, they fall apart. I can only imagine the diaster when my trash is picked up. I am hoping that it was just a bad batch of bags and the problem will be corrected, otherwise I will be purchasing a new brand of bags.
