  • End termination materials for reclosable polymeric bags
    Publication number: 20030082319
    Abstract: A process for preparing an end termination for use with a reclosable polymeric bag comprises providing a mixture comprising from about 70 to about 95 wt. % of a polyolefin, from about 5 to about 25 wt. % hydrocarbon, from about 0.01 to about 2 wt. % mold release agent, from about 0.1 to about 1 wt. % primary antioxidant, and at least about 0.06 wt. % secondary antioxidant. Next, the mixture is heated approximately to its appropriate application temperature and the melted mixture is injected into a mold. After the mixture is cooled to form the end termination, the end termination is ejected from the mold.
