    复合袋出现的里层现象的原因是什么?
    发布于:2020/09/03   平常的生活中复合包装袋随处可见,超市里面用来装零食,糖果,饼干的包装袋都是用复合塑胶袋来包装的,很多食品生产厂家在使用复合袋的时候经常会出现有袋子离成层的原因,今天就来帮大家分析一下为什么这些袋子会有离层的现象出现。
    In ordinary life, composite bags can be seen everywhere. The bags used to hold snacks, sweets and biscuits in supermarkets are packed with composite plastic bags. Many food manufacturers often have the reason for the bags to separate into layers when using the composite bags. Today, I will help you to analyze why these bags have the phenomenon of separation.
    一:材料不行引起的离层
    1: Separation caused by poor materials
    很多生产厂家以为所有袋子的材料都是一样的,其实不是这样的,对于产品的不同特性要求包装袋的材料是不一样的,有些产品油份大,有些产品需要进行高温处理,有些产品需要低温冷藏,所以袋子的材料选用不对造成的离层是很普遍发生的。
    Many manufacturers think that the materials of all bags are the same, but in fact, they are not. For different characteristics of products, the materials of packaging bags are different. Some products have large oil content, some products need high temperature treatment, and some products need low temperature refrigeration. The separation caused by the wrong material selection of bags is very common.

    二:复合技术不过关引起的离层
    2: Separation caused by the failure of composite technology
    复合必威中国网站就是把二层以上的材料组合在一起做成的包装袋,我们称为:复合袋。这些材料都是通过特殊的工艺把这些材料粘合在一起的,如果技术不过关,在复合的过程中胶水用的多或者少都会影响到以后袋子的离层情况。
    Composite plastic bag is a kind of packaging bag made of two or more layers of materials. We call it composite bag. These materials are bonded together by special technology. If the technology is not up to standard, the amount of glue used in the process of compounding will affect the separation of bags in the future.
    三:复合后熟化时间不够
    3: The curing time is not enough after compounding
    复合袋复合过后需要把复合好的材料放到一个恒温50度的一个环境去进行烘烤,烘烤的时间要达到48个小时,烘烤的目的就是为了把复合过程中的胶水烘烤干。有些生产厂家为了减少生产的时间,烘烤的时候不到就提前拿出来做袋子了,这样的袋子在过一段时间以后袋子一定会出现离层的情况的。
    After the composite bag is compounded, the composite materials need to be baked in an environment with a constant temperature of 50 degrees. The baking time should reach 48 hours. The purpose of baking is to dry the glue in the process of compounding. In order to reduce the production time, some manufacturers take them out to make bags in advance when it is not time to bake. After a period of time, the bags will be separated.
