For people in the corrugated box industry, the most troublesome thing is that the cardboard pressure line bursts when the autumn is dry and the carton feels soft when the spring rain is flooded. In fact, the factor that greatly affects the loss and quality of corrugated packaging is actually caused by the same factor - environmental humidity. In order to deepen your understanding of corrugated boxes, the editor will explain the impact of environmental humidity on the life of corrugated boxes.

According to scientific research, when the environmental temperature is constant at 23°C, with the increase of ambient humidity, the moisture content of corrugated boxes is positively correlated; With the increase of environmental humidity and moisture content, it gradually decreased, mainly because the cellulose in corrugated cardboard gradually became loose after absorbing moisture; the burst strength and puncture strength, with the increase of moisture content in the cardboard, showed a peak and then decreased. The curve changes, which indicates that too dry and too wet will have a great impact on the anti-burst ability of the carton.

Since corrugated box manufacturers will be affected by environmental humidity in the production and circulation process, this requires manufacturers to reasonably control the environmental humidity in these links, and users should also consider the environmental humidity of the destination of the goods, especially when transporting from the north to the south with high humidity, or when exporting by sea, it is particularly necessary to choose the appropriate corrugated box to protect the packaged products.

It is not difficult to see from the above that the most feared thing about corrugated boxes is dampness and water immersion. If damp, the paper will become soft and cannot meet the requirements, and then there is water immersion. Once the cardboard is immersed in water, it will open with the glue. Then it can only be treated as waste paper. So, how does the corrugated box prevent moisture?

First, when choosing a factory, be sure to check the surrounding sewer pipes and the horizontal position of your factory. The water goes to a low place. Once you build a factory in a low-lying area, the sewer pipes will not be able to drain for a while during heavy rain or showers, and cause stagnant water, which is the last thing we want to see, so carton entrepreneurs have to pay attention when choosing a location.

Second, because there are too many carton factories on the first floor, and it is a steel frame structure, the top is generally covered with iron sheets. It may be due to disrepair and rust to a non-existent degree, resulting in small stars or large areas of water leakage.The top priority is to transfer the cardboard or carton in the area to a place that does not leak, and use a bucket or basin to catch the leak on the ground, but be careful not to let the leaking water overflow, so as not to splash the ground, and replace it as soon as possible in good weather or repair. (Huaisheng is on the second floor, there are four layers in this building, so don’t worry about this)

Third, due to the rainy weather and humid weather, the finished carton and cardboard must be sized with the floor. For cardboard of different sizes, the lower is larger and the upper is smaller, and the lower is more and the upper is less, which not only solves the problem of pressure and bearing ability.

Fourth, pay attention to the normal use of ventilation equipment, which is conducive to air circulation, exhausts the moisture and the freshness of the air.
