QPF Inc., Wolff Walsrode AG and Votocel Filmes Flexiveis Ltda. will pool technology to develop new oriented polypropylene films on a pilot line at QPF's Streamwood, Ill., headquarters plant.

QPF has used the licensed Wolff technology to manufacture its OPP films since the early 1980s, said Mark Montsinger, QPF's business development director. Wolff of Walsrode, Germany, a unit of Bayer AG, makes and sells OPP films in Europe. Licensee Votocel of SÌo Paulo, Brazil, serves the South American market.

QPF disclosed the agreement during Pack Expo, but it has been in the works for some time, Montsinger said recently by telephone. It comes on the heels of parent U.S. Industries Inc.'s announcement that it will sell QPF to Hood Cos. of Hattiesburg, Miss., for $43.2 million.

Also at Pack Expo, QPF introduced a coextruded multilayer film for confectionery packaging, called Q-PET, that it claims performs like PET but costs less to produce. The film, which has a core of OPP and surface layers of PET, also is used for lid stock, and to package cereal bars and refrigerated foods in form, fill and seal applications.

At Streamwood, where QPF runs a pilot line, which is near production scale, Wolff and Votocel will help fund research and development of OPP films, such as a high-oxygen barrier film for food, Montsinger said.

In a separate agreement, Wolff has named QPF as its exclusive sales agent in North America.
