摘要 通过对6种不同LDPE/EVA共混比例的薄膜进行DSC分析和阻隔性分析,结果表明随着EVA质量分数的增加,LDPE/EVA薄膜的结晶度下降,透气性增大,水蒸气透过率和氧气透过率也随改性薄膜中EVA质量分数的增加而增大。 The DSC and barrier property analysis of six kinds of LDPE/EVA films with different blending proportions were carried out. The results showed that with increase of the proportion of EVA, the crystallinity of LDPE/EVA films declined. The gas permeahility increased because of the lower crystallinity. The water vapor transmission rate and the oxygen transmission rate of these films increased with the proportion of EVA increased.
