我们常用的复合包装袋为什么会产生分离?
发布于:2021/08/10 平常的生活中复合包装袋随处可见,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,今天顺鑫塑料厂家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 packaging bags can be seen everywhere. The packaging bags used for snacks, candy and biscuits in supermarkets are packed with composite plastic bags. Many food manufacturers often have the reason why the bags are separated into layers when using composite bags. Today, Shunxin plastic manufacturer will help you analyze why these bags are separated from layers.
一:材料不行引起的离层
1: Delamination caused by material failure
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. In fact, this is not the case. For different characteristics of products, the materials of packaging bags are different. Some products have high oil content, some products need high-temperature treatment, and some products need low-temperature refrigeration. Therefore, the separation caused by incorrect selection of bag materials is very common.
二:复合技术不过关引起的离层
2: Separation caused by failure of composite technology
复合塑料袋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 packaging bag made of more than two layers of materials. We call it composite bag. These materials are bonded together through special processes. If the technology is not qualified, more or less glue will affect the separation of bags in the future.
三:复合后熟化时间不够
3: Insufficient curing time 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 compounding process. In order to reduce the production time, some manufacturers take out the bags in advance before the baking time. Such bags will be separated after a period of time.
上面顺鑫塑料厂家所说的几点就是复合包装袋离层的主要的原因的,所以大家在选择复合袋生产厂家的时候一定要考察了解清楚,这样才会避免产品在使用过程中出现的离层情况对产品造成的影响。
The above points mentioned by Shunxin plastic manufacturer are the main reasons for the delamination of composite packaging bags. Therefore, when selecting composite bag manufacturers, we must investigate and understand clearly, so as to avoid the impact of delamination on on the products in the process of use.
