Study on Preparation and Properties of Medical Stone/LDPE Fresh-keeping Packaging Film
摘要
Abstract
LDPE and medical stone were used as the main raw material to produce fresh-keeping packa-ging film.Stearic acid was used as dispersant promoted the medical stone powder to disperse in the resin and sorbitol used as a hygroscopic when produce the film.The influence of medical stone content and particle size, stearic acid content and sorbitol content were studied by mechanical test,moisture permeability,oxygen per-meability and infrared spectroscopy.The results show that when adding 20% of 325 mesh medical stone with the best additives amount:proportion of medical stone/stearic acid was 10/2,sorbitol content was 1% that material have a best properties.关键词
