本文介绍一种新研制的用于香烟及食品包装的真空镀铝纸。它是以双拉伸聚丙烯薄膜为基材,经真空镀铝后,以热融性树脂为粘接剂,将镀铝层转移到纸张表面的一种新型包装材料,故称转移法真空镀铝纸。这种材料综合了压延铝箔纸与涂胶镀铝纸的优点,其性能在许多方面超过了前两者。(详见本刊87—5期封三)。本文简要介绍这种材料的生产过程、使用性能及其原材料的选择要点。
This article describes a newly developed vacuum aluminized paper for cigarettes and food packaging. It is based on double-stretch polypropylene film substrate, the vacuum aluminum, with hot-melt adhesive resin, the aluminum layer is transferred to the paper surface of a new type of packaging material, so that transfer method vacuum plating Aluminum paper. This material combines the advantages of calendered aluminum foil with glued aluminum paper, in many ways outperforming the former two. (See this issue 87-5 cover three). This article briefly describes the production process of this material, the use of performance and the selection of raw materials points.
