Introduction of moisture-proof methods for food packaging boxes

One method can use paraffin, microcrystalline wax, polyethylene wax, beeswax, white wax, carnauba wax, montan wax and other animal and vegetable waxes, which can be moisture-proof and waterproof after being emulsified and coated on cardboard, because the cost is low. Commonly used methods.

Another water removal agent is prepared by using chromium trioxide in propanol-hydrochloric acid solution, mixed with stearic acid, and has the characteristics of anti-mildew and anti-fouling. There are different formulations of hydrophobic agents currently on the market. If resin, starch or gel moisture-proof agent is added to pulp to make moisture-proof paper, it is naturally convenient for the production of food packaging boxes. Although it is necessary to increase the cost of the original food packaging box, the moisture-proof method of the food packaging box has been introduced, but the total cost is still cost-effective.
