As an important source of nutrition for infants and many consumers, the safety and functionality of milk powder packaging are very important. During the production, storage and transportation of milk powder bags, static electricity is easily generated due to friction with raw materials. Static electricity will not only absorb dust and impurities, affect the appearance of milk powder, but also cause the packaging to be not tightly sealed, accelerate the deterioration of milk powder, and reduce the quality of products. We have encountered such problems in the actual production of orders. In view of the static electricity generated by bags and the phenomenon of milk and milk powder hanging on the wall, we have carried out a practical test of anti-static electricity. Here we share our experience. The application of antistatic agent provides an effective way to solve the electrostatic problem of milk powder bag, and has many influences on the packaging of milk powder bag.
In the production process of milk powder bags and other dairy packaging bags, the existence of static electricity will make the film materials adsorbed to each other, and it is difficult to smoothly feed and subsequent processing, resulting in production interruption and reduce production efficiency. The addition of antistatic agent can reduce the surface resistance of the material, accelerate the charge leakage, and effectively reduce the static electricity generation. Taking polyethylene (PE) milk powder bag as an example, after adding an appropriate amount of non-ionic antistatic agent, the surface resistance of the material can be reduced from 10¹²Ω to less than 10⁹Ω, so that the adsorption between the films in the production process is greatly reduced, the feeding is smooth, and the heat sealing, printing and other processes can be efficiently carried out. This not only reduces the equipment commissioning time, reduces the scrap rate, but also improves the overall production efficiency and reduces the production cost.
For consumers, the static electricity generated by the milk powder bag will cause the milk powder to adsorb on the inner wall of the bag, which is not easy to pour out, resulting in waste. The antistatic agent can reduce the electrostatic adsorption between the milk powder and the bag, so that the milk powder is easier to pour out of the bag. When the anti-static agent is added to the milk powder bag, the fluidity of the milk powder in the package is improved, and consumers can easily pour out all the milk powder during use, improving the use experience. In addition, static electricity may also make it difficult to open the milk powder bag. After adding antistatic agents, the electrostatic effect at the opening of the bag is weakened, which is convenient for consumers to open and access the milk powder.
The storage environment of milk powder has great influence on its quality. Dust and impurities adsorbed by static electricity may become a breeding ground for microorganisms and pollute milk powder. At the same time, the spark generated by static electricity may also cause dust explosion under certain conditions, which has serious safety risks. The use of antistatic agents can avoid these problems and ensure the quality and safety of milk powder during storage and transportation. By reducing the electrostatic hazard, reduce the adsorption of dust and impurities, create a relatively clean storage environment for milk powder, and extend the shelf life of milk powder. In addition, the antistatic agent effectively prevents the generation of electrostatic sparks, reduces the risk of dust explosion, and ensures the safety of milk powder in the production, storage and transportation.
With the continuous enhancement of environmental awareness, the development of environmentally friendly antistatic agents has become an industry trend. Some new antistatic agents can not only effectively antistatic, but also have degradable characteristics, reducing the pollution to the environment. The use of such antistatic agents in milk powder bag packaging not only meets the functional needs of packaging, but also meets the requirements of environmental protection, and helps to promote the development of the entire packaging industry in a green and sustainable direction. At the same time, the application of antistatic agents reduces the waste of packaging materials caused by electrostatic problems, improves the utilization of resources, and further reflects its positive significance in environmental protection.
Although antistatic agents have many positive effects on milk powder bag packaging, it is also necessary to pay attention to reasonable selection and control of the addition amount during use. The compatibility of different types of antistatic agents and milk powder bag materials is different, if the improper selection, may affect the physical properties and chemical stability of the packaging material. In addition, the mobility of antistatic agents may also lead to their precipitation on the packaging surface, which has a potential impact on the quality of milk powder. Therefore, production enterprises need to ensure the safe use of antistatic agents through strict experiments and quality testing.
The application of antistatic agents is of great value to milk powder bag packaging, which helps the packaging industry achieve environmental protection and sustainable development while improving production efficiency, convenience of use and product quality and safety. With the continuous progress of technology, the performance of antistatic agents will continue to be optimized, bringing more innovation and change to the milk powder packaging industry.
