快递袋自带的胶为什么不会出现脱胶？

快递袋的主要功能是包装快递。目前，网上购物的快速发展促使快递袋广泛应用于物流、包装和运输！密封程度高，密封方式方便。当我们收到快递时，我们偶尔会看到，即使快递袋坏了，密封一般也不会爆炸。可以知道，热溶胶对快递袋的附着力很强，但胶粘剂长期暴露在水中很容易导致胶脱胶，但快递袋上很少有水脱胶的问题。原因是什么？让我们看看。

The main function of a delivery bag is to package express delivery. At present, the rapid development of online shopping has led to the widespread use of express bags in logistics, packaging, and transportation! High sealing degree and convenient sealing method. When we receive a package, we occasionally see that even if the package bag is broken, the seal generally does not explode. It can be known that thermosols have strong adhesion to express delivery bags, but long-term exposure to water can easily lead to adhesive delamination. However, there is rarely a problem of water delamination on express delivery bags. What is the reason? Let's take a look.

用于快递袋的热溶胶实际上需要具备几个非常重要的特性，其中之一就是破碎材料的效果。当快递袋生产制造时，袋子的密封需要涂胶的地方不会被加热后的胶水破坏，但塑料快递袋的表面会有一些程度的破坏，这恰好是我们涂胶所需要达到的效果。这种快递袋中使用的热溶胶实际上是压敏热溶胶。即使在室温下，也有很好的初始粘度。只需稍微压一下密封就可以非常牢固，保证密封效果，保证物品包裹完好。所以每次拆卸快递，都会有一种情况，就是直接从密封旁边撕下来，因为制作快递袋所用的塑料分子比较松散，只需要一点力就可以撕下一层薄薄的塑料。但是密封的地方特别坚固，很难撕开！！这是一个很好的破碎效果。

The hot melt adhesive used for express delivery bags actually needs to have several very important characteristics, one of which is the effect of crushing materials. When producing express delivery bags, the sealing area of the bag that needs to be glued will not be damaged by the heated glue, but the surface of the plastic express bag will have some degree of damage, which is exactly the effect we need to achieve when applying glue. The hot melt adhesive used in this delivery bag is actually a pressure-sensitive thermosol. Even at room temperature, it has a good initial viscosity. Just a slight pressure is needed to seal it very firmly, ensuring the sealing effect and ensuring the package of the item is intact. So every time the package is disassembled, there is a situation where it is directly peeled off from the side of the seal, because the plastic molecules used to make the package are relatively loose, and a thin layer of plastic can be peeled off with just a little force. But the sealed area is particularly sturdy and difficult to tear open!! This is a very good crushing effect.

因为这种松散的分子结构可以与热溶胶形成很大的空间，塑料表面的加热破坏了塑料分子胶的冷却，可以再次形成稳定的结构，所以粘度非常牢固，即使整个快递袋浸泡在水中，也很难使密封脱胶。

Because this loose molecular structure can form a large space with the thermosol, the heating on the plastic surface disrupts the cooling of the plastic molecular glue, which can form a stable structure again. Therefore, the viscosity is very strong, and even if the entire express bag is soaked in water, it is difficult to seal and delaminate.

而且快递袋本身表面比较滑，一般滴水后很快就会滑走，不会停留。即使运输过程中下雨，也不用担心。雨水不影响快递袋的密封性。当然，你的袋子需要密封，运输也没有损坏。因此，我们可以知道热溶胶在快递袋上的粘合效果非常好，在日常生活中也能感受到粘性

Moreover, the surface of the express bag itself is relatively smooth, and it usually slides away quickly after dripping water without stopping. Even if it rains during transportation, don't worry. Rainwater does not affect the sealing of the express bag. Of course, your bag needs to be sealed and not damaged during transportation. Therefore, we can know that the adhesive effect of thermosols on express delivery bags is very good, and they can also be felt to be sticky in daily life
