I just made a batch of lip balm and labels to go on the tubes. The tubes by the way are the slim stick style. After labeling all of them I noticed that the labels were starting to come loose. No matter how much rubbing I have done, it isn't working. I wiped off the tubes to make sure there was no greasy residue on the. Any suggestions as to what to do? Should I try to apple a small piece of clear tape (such as the wide packing style tape) around the label before applying the shrink wrap? This is so aggravating!
