We all know the word "packaging" very well. It is also a popular word nowadays. The various packaging in major shopping malls and supermarkets makes us dizzy and brings great advantages to sales. However, the effects of packaging are also different. Some packaging is for delicate and convenient sales, some packaging is for transportation, and some is for storage. Different effects also bring different packaging materials. The packaging materials are diverse, mainly including wooden box packaging, woven bag packaging, cloth bag packaging, plastic box packaging, carton packaging, etc. However, carton packaging is widely used.

The moisture-proof work of Shenyang corrugated boxes should be done well, or it will affect the life and quality of use. We still need to pay attention to this. It is very useful to master effective moisture-proof methods.
One method can use animal and vegetable waxes such as white wax, microcrystalline wax, polyethylene wax, beeswax, white wax, carnauba wax, montane wax, etc. After emulsification, it can also be applied to the paper board to prevent moisture and water. Because of its low cost, it is now used in many ways.
Another kind of water extracting agent is made by reducing chromium trioxide in propanol hydrochloric acid solution and cooperating with stearic acid, which has the characteristics of mildew prevention and antifouling. Now there are different formulations of water extracting agents on the market. If the resin, starch or glue moisture-proof agent is added into the pulp to make moisture-proof paper, the production of cartons will be naturally convenient. Although this will increase the cost of some base paper cartons, the introduction of moisture-proof methods for corrugated cartons is cost-effective.

What factors affect the flatness of corrugated boxes? Here is a brief introduction.
1. If the spray equipment used in carton packaging is different, the humidity of the paperboard may be different. The difference in moisture content between the outer edge side and the inner core side is the change of flatness.
2. Because there are many types of cardboard used for corrugated carton packaging, which are different in quality, type and other aspects, the flatness of the carton will also be affected during packaging.
3. The humidity in the storage environment will also affect the flatness of corrugated boxes. The higher the humidity in the storage environment, the greater the impact on the flatness of corrugated boxes.
Carton packaging, as an indispensable part of modern logistics, bears the important responsibility of containing, maintaining products and looking beautiful, so we must pay attention to the factors that may affect the flatness of cartons.
