摘要
通过对薄膜透气机理的研究,确立了一种方便可行的透气测试方法,为薄膜应用于食品包装提供较快、较实用的选择数据。并分别测试了江西塑料制品试验厂生产的高压聚乙烯膜在常温。
A convenient testing method is determined to supply faster and more practical data for selecting food packaging film based on the study of the gas permeability mechanism of packaging film. And testings are made on the CO_2 and O_2 permeability of LDPE manufactured by Jiangxi Plastic Stuffs Factory under the conditions of normal atmospheric temperature and pressure.
