快遞袋自帶的膠為什么不會出現(xiàn)脫膠？

快遞袋的主要功能是包裝快遞。目前，網(wǎng)上購物的快速發(fā)展促使快遞袋廣泛應(yīng)用于物流、包裝和運(yùn)輸！密封程度高，密封方式方便。當(dāng)我們收到快遞時(shí)，我們偶爾會看到，即使快遞袋壞了，密封一般也不會爆炸?？梢灾?，熱溶膠對快遞袋的附著力很強(qiáng)，但膠粘劑長期暴露在水中很容易導(dǎo)致膠脫膠，但快遞袋上很少有水脫膠的問題。原因是什么？讓我們看看。

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.

用于快遞袋的熱溶膠實(shí)際上需要具備幾個(gè)非常重要的特性，其中之一就是破碎材料的效果。當(dāng)快遞袋生產(chǎn)制造時(shí)，袋子的密封需要涂膠的地方不會被加熱后的膠水破壞，但塑料快遞袋的表面會有一些程度的破壞，這恰好是我們涂膠所需要達(dá)到的效果。這種快遞袋中使用的熱溶膠實(shí)際上是壓敏熱溶膠。即使在室溫下，也有很好的初始粘度。只需稍微壓一下密封就可以非常牢固，保證密封效果，保證物品包裹完好。所以每次拆卸快遞，都會有一種情況，就是直接從密封旁邊撕下來，因?yàn)橹谱骺爝f袋所用的塑料分子比較松散，只需要一點(diǎn)力就可以撕下一層薄薄的塑料。但是密封的地方特別堅(jiān)固，很難撕開??！這是一個(gè)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?yàn)檫@種松散的分子結(jié)構(gòu)可以與熱溶膠形成很大的空間，塑料表面的加熱破壞了塑料分子膠的冷卻，可以再次形成穩(wěn)定的結(jié)構(gòu)，所以粘度非常牢固，即使整個(gè)快遞袋浸泡在水中，也很難使密封脫膠。

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.

而且快遞袋本身表面比較滑，一般滴水后很快就會滑走，不會停留。即使運(yùn)輸過程中下雨，也不用擔(dān)心。雨水不影響快遞袋的密封性。當(dāng)然，你的袋子需要密封，運(yùn)輸也沒有損壞。因此，我們可以知道熱溶膠在快遞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
