Abstract

The effect of structure on the spectral light transmittance of a polymer film material and its light aging resistance is studied. Three types of multilayered films derived from high-pressure polyethylene; high- and low-pressure polyethylene; and high-pressure polyethylene, polyamide, and copolymer of ethylene with vinyl alcohol are investigated. These films are prepared by co-extrusion and are used for the production of flexible packaging materials in the form of laminates. Using the technique of differential scanning calorimetry, the comparative light resistance of the layers incorporated in the films is determined.

用于软包装生产的多层聚合物薄膜的比较透光率和耐光性

摘要

研究了结构对高分子薄膜材料光谱透光率及其耐光老化性的影响。由高压聚乙烯衍生的三种类型的多层薄膜；高压和低压聚乙烯；并对高压聚乙烯、聚酰胺和乙烯与乙烯醇的共聚物进行了研究。这些薄膜通过共挤出制备，用于生产复合材料形式的软包装材料。使用差示扫描量热法技术，确定膜中结合的层的比较耐光性。
