Brushes are packaged at Oral-B's Iowa City IA plant at 240/min. Single 12.5-mil polyvinyl chloride "forms" containing 12 thermoformed toothbrush compartments are supplied by Alloyd (DeKalb IL). Brushes are placed automatically in the cavities and an 8-mil PVC backing card is RF-sealed to the blister. Two spot labels are applied to the tops of the unusually cut blisters on equipment from Sonoco Machine Div. (Delran NJ). Nickelodeon- and Rugrats-brand toothpaste tubes hold 4.2 oz of product. The 12-mil seven-layer tubes use ethylene vinyl alcohol as a primary barrier layer. They're printed in six colors on a flexo press by supplier Thatcher Tubes (Florence KY). Hinged flip-top polypropylene closures come with inserts manufactured with one of eight different-shaped dispensing orifices designed to appeal to children.
