一次性纸餐盒应该如何做好防潮处理?包装一次性纸餐盒在进行防潮处理的时候，不只要保护包装物不受水的浸湿，还要防止水对一次性纸餐盒自身的浸湿。

How to do moisture-proof treatment for disposable paper lunch boxes? When packaging a disposable paper lunch box for moisture-proof treatment, it is not only necessary to protect the packaging from water, but also to prevent water from wetting the disposable paper lunch box itself.

因为一次性纸餐盒在水浸湿后，它自身的抗压强度、耐破度都会下降，这样会严重影响包装的质量。包装一次性纸餐盒进行防潮制造，一般选用涂布防水剂的方法来处理。因而，依据防水剂的作用可以将防潮一次性纸餐盒的制造方法分为：暂时性防水处理和持久性防水处理。

Because after the disposable paper lunch box is soaked in water, its compressive strength and bursting strength will decrease, which will seriously affect the packaging quality. The packaging of disposable paper lunch boxes for moisture-proof manufacturing generally adopts the method of coating waterproof agent. Therefore, according to the function of waterproof agent, the manufacturing method of moisture-proof disposable paper lunch box can be divided into temporary waterproof treatment and permanent waterproof treatment.

在一次性纸餐盒市场上包装一次性纸餐盒在生产过程中选用暂时性防水剂处理后，具有暂时防水功用。当水短时间落于其上时，不沾湿而成水滴，能防止水浸透纸板。包装一次性纸餐盒这种涂料早期用于织物纤维上，后来才用于纸板的处理。因而大多树一次性纸餐盒厂就选用拔水剂的叫法。拔水剂是一种蜡乳液，固体含量一般为：48%～51%，它的特点是在运用时可用30倍左右的水稀释。

In the disposable paper lunch box market, the disposable paper lunch box has temporary waterproof function after being treated with temporary waterproof agent in the production process. When water falls on it for a short time, it will not get wet and become water droplets, which can prevent water from soaking the cardboard. Packaging disposable paper lunch boxes This coating was used on fabric fibers in the early stage, and then used for the treatment of cardboard. Therefore, most of the tree disposable paper lunch box factories choose the name of water extractor. The water extractor is a wax lotion with a solid content of 48%~51%. It can be diluted with about 30 times water when used.

当遇水时，水在这个纸板上不滋润，构成水滴滚落，从而到达防水的作用。别的因为蜡乳液中蜡的粒径一般都比一般的高分子乳液粒径大，要往纸纤维深处浸透也难，一起拔水剂一般对明矾一类化学品灵敏，在纸外表往往很快破乳而沉积下米，因而拔水剂中的蜡粒子绝大部分只在纸面上很薄的一层存在。

When encountering water, the water will not moisturize on the cardboard, forming water droplets rolling down, thus achieving the waterproof effect. In addition, because the particle size of wax in wax lotion is generally larger than that of general polymer lotion, it is also difficult to penetrate into the deep part of paper fiber. Together with the water extractor, it is generally sensitive to alum and other chemicals, and it tends to quickly break the emulsion on the surface of paper and deposit, so most of the wax particles in the water extractor only exist in a thin layer on the paper surface.
