I got a roll of Siser mask with my new Titan 3 plotter a couple of weeks ago, but hadn't needed to open it. Tonight I was working late in my shop and happened to look up and see a couple of ants on the sealed box, so I swiped them off and more appeared... so my wife and I opened the box to find it full of red ants! They were all between the layers of material and had a full nest happening inside the roll! Is that glue like catnip to them or what? Anybody ever seen this? After we unrolled the material we also found "something" growing on the backing on the material too. Keep in mind, this box has been sealed, taped up completely since I got it. Anybody else ever have this, or have suggestions on how to prevent it???
