We all know carton If it cannot be used after encountering water, how should it be protected? What are the methods for preventing moisture in cardboard boxes?

In humid environments like summer, even if the cardboard box is placed far away from water sources, it will be soaked by the humid air in the air, greatly reducing its strength and durability. Therefore, it is important to carry out moisture-proof treatment on the cardboard box itself.

Generally speaking, the moisture-proof treatment for cardboard boxes is to apply a layer of waterproofing agent on the outside of the box. This treatment method is also divided into temporary waterproofing and long-term waterproofing.

Temporary waterproof is to apply a layer of wax lotion on the surface of the carton, so that when a water drop falls on the carton, it will not be soaked but will slip down, forming a good waterproof effect. However, because the wax has poor adhesion and is easy to fall off, it will fail after a period of time, so this waterproof effect is called temporary waterproof.

Long term waterproof is to apply a layer of waterproof agent containing rosin derivatives or carboxylated polymer lotion on the carton. This material can be compatible with wax, and can be firmly attached to the carton without failure for a long time, thus forming a long-term waterproof effect.

1. When producing and processing cardboard boxes, applying moisture-proof oil or water repellent to the boxes can improve their strength and achieve the goal of moisture resistance. However, the cost will be much higher!

2. If moisture-proof oil or water repellent is not added to the cardboard box during production, attention should be paid to the storage environment. It should be stored in a relatively dry and well ventilated place, where the possibility of moisture is relatively small. It is particularly important to note that cardboard boxes cannot be placed directly on the ground, and pallets or other things should be used to cushion them on the ground;

3. In Customized cardboard boxes When ordering, pay attention to the quantity and calculate how much you can use first. If you order too many, the longer they are stored, the more likely they are to get damp. It is best to plan for a monthly quantity.

After reading the above, we can understand that the moisture-proof method of cardboard boxes is not only something that manufacturers can do well, they also need to do a good job in moisture-proof of cardboard boxes themselves.
