​What are some ways to make cartons moisture-proof?

We all know that cartons cannot be used when exposed to water, so how to protect them? What are the ways to prevent moisture in cartons?

In a humid environment like summer, even if the carton is placed far away from the water source, the carton will be soaked due to the humid air in the air, which will greatly reduce the strength and bursting resistance, so the carton itself should be treated with moisture-proof Very important.

Generally speaking, the moisture-proof treatment of cartons is to apply a layer of waterproofing agent on the outside of the carton. This treatment method is also divided into two types: temporary waterproofing and long-term waterproofing.

Temporary waterproofing is to apply a layer of wax emulsion on the surface of the carton, so that when water droplets fall on the carton, they will not soak but slide down, forming a good waterproof effect. However, because the adhesion of wax is very poor, it is very difficult to It is easy to fall off, so it will lose its effectiveness after a while, so this waterproof effect is called temporary waterproofing.

Long-term waterproofing is to apply a layer of waterproofing agent containing rosin derivatives or carboxylated polymer emulsion on the carton. This substance is compatible with wax and can be firmly attached to the carton without losing effect for a long time. This forms Provides a long-lasting waterproof effect.

1. When producing and processing cartons, apply moisture-proof oil or water-splashing agent to the cartons. This will improve the strength of the processed cartons and achieve the purpose of moisture-proofing. Of course, the cost will be much higher!

2. If the cartons are produced without adding moisture-proof oil or water-splashing agent, you must pay attention to the storage environment. If they are stored in a dry and well-ventilated place, the possibility of getting damp is relatively small. A special reminder: the cartons cannot be placed directly on the ground. , use something like a pallet to pad the floor;

3. When ordering cartons, pay attention to the quantity, and first calculate how much you can use. If you order too many, the longer they are stored, the more susceptible they are to moisture. It’s best to plan a month’s supply.

After reading the above, we can understand that the moisture-proof method of cartons is not only done by the manufacturer, but also needs to be moisture-proofed by the cartons themselves.
