  • Use of surface active agents for improved cooling of thermoplastic film webs
    Patent number: 5049223
    Abstract: An improved cooling process for thermoplastic film webs, profiles, or shapes and interlocking closure profiles extruded onto film webs for use on reclosable bags or containers is provided. A mixture of a surfactant and water is used to cool film webs or closure profiles which have been extruded and secured onto a film web. The surfactant lowers the surface tension of the water, improving its wetting properties and providing faster cooling of the film. The resulting film structures are more stable and consistent in structure.
