It just occurred to me to try my Food Saver Seal-a-meal vacuum packager (model VAC 1075) to weld Capri Sun pouches. I mean it seals heavy plastic bags, why not Capri Sun pouches? Well the experiment was unsuccessful. I tried it on two pouches and pressed down hard and put them through 3 sealing cycles, and they barely even got warm. Darn I was really hoping that one would work.
