The Uline catalog offers the most beautiful array of toxic industrial products for the production of more toxic industrial products. I cannot turn away. Oh, poly tubing and a heat sealer! I would bag everything in my house. Bobbie pins, bagged. Dog kibble, bagged. Tiny Playmobil swords, bagged. Pennies, bagged. Old correspondence, bagged. What would you heat seal in a polybag?
