| 摘 要： | 通过挤出吹塑法制作了聚乙烯薄膜(PE),以流延法制作了热能触发式变色薄膜,通过复合机理把2 种膜复合在一起。通过对复合膜的力学性能和光学性能的研究,发现了复合膜的力学性能和光学性能有所下降,且变色性能略微发生了变化,但保留了根据温度而变色的优良性能。各项指标表明PE/ 热能触发式变色薄膜可以应用于食品包装。

| Abstract: | PE membrane was prepared by extrusion blow molding method and heat triggered color changing film was prepared by tape casting method. The two kinds of membranes were composited. The mechanical property and the optical performance of the composite film were studied. The results showed that the mechanical properties and optical performance of the composite film is falling; the composite film retains excellent discoloration performance. All of the indicators proved that the PE/ heat triggered color changing composite film can be used in food packaging. |
