I'm having a problem with my conditioner bars. The melting in the heat isn't a surprise. What is a surprise is that it seems to somehow leak. The packages are sealed and shrunk with a heat gun. With it leaking, it's leaking all over everything in my storage boxes. I am using the smell through shrink wrap. I never find the wrap damaged in any way so I'm wondering if it's possible that the tiny hole allowing the smell to come through are the problem. Do you you think I should change to pvc shrink wrap for my conditioner bars?
