The use of water-soluble pouches for insecticides is not new nor is the idea of packaging those pouches into a flexible envelope. Dow's Dursban insecticide is a good example of the concept (see PW Nov. '94 p. 38). However Kansas City MO-based Bayer Corp. Agricultural Div. was searching for an even more involved package for its new product Premise® 75 Insecticide. Sold only to licensed pest control operators (PCOs) the company's top priorities were user-friendliness and safety. Features such as tamper-evidence reclosability and individual compartments for premeasured packets would eliminate the PCO's need for measuring and protect against moisture. "We really tried to forget everything we knew about packaging and create this envelope from scratch" says Cecil Childers former product manager for Premise 75. Childers says he and packaging designers at Bayer were unaware of the Dursban package at the time of Premise 75's conception. But they had worked with the converter of the Dursban envelope Pactech (Rochester NY) before and they called on the company again for help with the Premise 75 package. Pleased with Pactech's material they next contacted BPS (West Helena AR) to copack their new product. The package starts with Chris Craft's (South Holland IL) Monosol® water-soluble polyvinyl alcohol film. Pouches holding 2.2 oz of powdered product are formed filled and sealed by BPS. The pouches are then inserted into premade laminated envelopes from Pactech. One pouch fits into each of four separate compartments aligned horizontally. BPS currently produces about 7 PVA pouches/shift or 1 envelopes/shift. They're hand-packed into corrugated shippers holding four envelopes and then sent to warehouses or distribution centers. Bayer is keeping its customers including PCOs like the Atlanta-based Orkin Exterminating Co. Inc. happy with the new package. Orkin plans to sell its customers on the premise behind Premise 75: this is the first product of a new chemistry of "termiticides." Premise 75 is the first powdered concentrate says Bayer. It's said to be odorless safe when used near humans and pets and environmentally friendly.
