      我們常用的復合包裝袋為什么會產生分離?
      發布于:2021/08/10 平常的生活中復合包裝袋隨處可見,超市里面用來裝零食,糖果,餅干的包裝袋都是用復合塑膠袋來包裝的,很多食品生產廠家在使用復合袋的時候經常會出現有袋子離成層的原因,今天順鑫塑料廠家就來幫大家分析一下為什么這些袋子會有離層的現象出現。
      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:材料不行引起的離層
      1: Delamination caused by material failure
      很多生產廠家以為所有袋子的材料都是一樣的,其實不是這樣的,對于產品的不同特性要求包裝袋的材料是不一樣的,有些產品油份大,有些產品需要進行高溫處理,有些產品需要低溫冷藏,所以袋子的材料選用不對造成的離層是很普遍發生的。
      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:復合技術不過關引起的離層
      2: Separation caused by failure of composite technology
      復合塑料袋就是把二層以上的材料組合在一起做成的包裝袋,我們稱為:復合袋。這些材料都是通過特殊的工藝把這些材料粘合在一起的,如果技術不過關,在復合的過程中膠水用的多或者少都會影響到以后袋子的離層情況。
      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:復合后熟化時間不夠
      3: Insufficient curing time after compounding
      復合袋復合過后需要把復合好的材料放到一個恒溫50度的一個環境去進行烘烤,烘烤的時間要達到48個小時,烘烤的目的就是為了把復合過程中的膠水烘烤干。有些生產廠家為了減少生產的時間,烘烤的時候不到就提前拿出來做袋子了,這樣的袋子在過一段時間以后袋子一定會出現離層的情況的。
      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.
      上面順鑫塑料廠家所說的幾點就是復合包裝袋離層的主要的原因的,所以大家在選擇復合袋生產廠家的時候一定要考察了解清楚,這樣才會避免產品在使用過程中出現的離層情況對產品造成的影響。
      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.
