For many years in the field of sterilization and disinfection of packaging containers in the cosmetics industry in China, there is a defect in the use of the old technology. The international advanced disinfection industry is used for reference, and the “GMP verification guideline†and “disinfection technical specification†formulated by the Ministry of Health are followed to design and manufacture. "JZCF-B" series packaging container ozone disinfection system has obvious disinfection effect. Reprinted in Chinese bottle net
Collapsible Gift Box is very popular in worldwide as it is luxury, cheap and can be flat packed to save freight. The collapsible Gift Box or flat pack container is assembled easily before used as there are adhesive taps or magnet on the four corners. This kind of rigid gift box is usually closed with magnet and ribbon.

First, the principle of ozone sterilization
Ozone sterilization is a biochemical oxidation reaction. Ozone oxidation decomposes the enzymes necessary for oxidizing glucose inside the bacteria; it can also directly interact with bacteria and viruses, destroying cell walls and ribonucleic acids, and breaking down macromolecule polymers such as DNA, RNA, proteins, lipids, and polysaccharides. The process of material metabolism growth and reproduction is destroyed; it can also penetrate cell membrane tissue, invade the cell membrane and act on the outer membrane lipoprotein and internal lipopolysaccharide, causing the cell to undergo permeability distortion, leading to cell lysis and death, and will die. The genetic, parasitic, parasitic virion, bacteriophage, mycoplasma, and pyrogens (bacterial viral metabolites, endotoxins), etc. Throughout the perspective of aseptic technology on the role of microorganisms can be divided into three kinds of antibacterial, bactericidal and bacteriolytic, application of ozone as a sterilizing agent is bacteriolytic.
In the “Disinfection Technical Specifications†promulgated by the Ministry of Health in 1991, there is also a description of the principle of ozone sterilization:
"Scientific research shows that ozone has a very strong bactericidal effect." "Ozone is unstable under normal temperature and atmospheric pressure and quickly decomposes itself into oxygen (O2) and a single oxygen atom (O). The latter is very strong. Active, it has a strong oxidizing effect on bacteria.Oxygen oxidation breaks down the enzymes necessary for oxidizing glucose inside the bacteria, destroys the cell membrane, kills it, and the excess oxygen atoms will recombine themselves into ordinary oxygen molecules (O2). There is no toxic residue, so it is called 'pollution-free disinfectant'. It not only has a strong ability to kill a variety of bacteria (including hepatitis virus, E. coli, green bacilli, and bacteria, etc.), but also kills. Mold is also very effective."
Second, the working principle and system composition
Through the practice of ozone sterilization and disinfection of different packaging containers, the corresponding corresponding effective ozone disinfection concentration is counted, so as to obtain the effective concentration of the time period, and then the data is set to the centralized electronic control system for storage. In production, it can be automatically Control the entire disinfection process. The effective concentration of ozone takes place within a specified period of time to completely sterilize the packaging material until the exhaust gas is discharged and is discharged into the atmosphere (the exhaust emission meets the national environmental protection standard ≤ 0.2mg/M3 ozone concentration).
The system is composed of air source processing equipment, ozone generation equipment, ozone concentration monitoring and testing equipment, tail gas discharge destruction equipment and centralized electrical automatic control as the main component of the disinfection system.
The air source processing equipment supplies the processed gas to the ozone generating device to generate ozone, and diffuses into the cavity of the packaging material through the pipeline in the disinfection chamber. When the ozone concentration and the action time in the disinfection chamber reach the specified value, the ozone generating device stops working. After the exhaust gas destruction equipment starts to warm up, when the temperature reaches the set value, the exhaust gas discharge equipment starts, discharges the gas in the tank to the exhaust gas destruction equipment, forcing it to rapidly decompose and reduce and discharge into the atmosphere.
System Process: Air Source Treatment - Ozone Generator - Disinfectant - Exhaust Emission
Third, compared with the traditional cosmetic packaging container sterilization method:
1. Good disinfection and sterilization effect, no environmental protection, and lasting effect.
At present, cosmetic manufacturers generally use high-temperature drying, ultraviolet irradiation, disinfectant dipping, 75% alcohol solution dipping, and ethylene oxide for packaging containers. There are defects such as incomplete sterilization, high energy consumption, complicated operation process, and some even secondary pollution. The ozone disinfection process completely compensates for the lack of old technology, reduces the cost of human, material, and force in the disinfection process, improves production efficiency, and has no residue. E. coli, Staphylococcus aureus, Bacillus, Neisseria gonorrhoeae killing effect is very good. Since ozone is a gas sterilizer, under normal operating and storage conditions, there is no water carrier on which bacteria can survive, so the effect is reliable and lasting.
2, after the sterilization package use effect
Because ozone is a gas at room temperature and the concentration is controllable, the effect of ozone on the aging of corrosive materials such as PVC and PE is comparable to that of alcohol and formaldehyde. The package material does not deform, does not affect the printing adhesion of the package material, and normal code can be performed.
3, economic contrast
According to the user's use, the production costs of "ozone" and "formaldehyde-ethanol" new and old disinfection methods are compared as follows:
Formaldehyde-ethanol sterilization method:
Disinfection amount of packaging materials - 15-20 million pieces/day
Operators - 15 (average salary 800 yuan/month)
Ethanol consumption - 400-500kg/month (about 5,000 yuan per ton)
Then: annual salary costs are calculated according to peak season production of eight months 96,000 yuan
Consumables costs are also calculated according to eight months of 18,000 yuan
Total of two items: 114,000 yuan
Ozone disinfection method:
Disinfection amount of packaging materials - 15-20 million pieces/day
Operating staff - 4 people (average salary 800 yuan/month)
Electricity Consumption - Each time you open the disinfection warehouse, you will use 3KW electricity. If you open the warehouse 5 times a day, you will consume 15KW. (The electricity fee is 2.5 yuan/KW industrial electricity).
Then: Annual salary costs are calculated as peak season production of eight months and 25,600 yuan
The electricity fee is also calculated based on eight months of 13,500 yuan.
Two total: 39,100 yuan
The cumulative cost difference between the above new and old disinfection processes is 114,000-39,100 units per year = 74,900 units. If compared with the ozone disinfection system, the investment can be recovered in 12-14 months.
In summary, in recent years, our company has developed an ozone disinfection system for the disinfection of cosmetic packaging materials. This project has been used by cosmetics companies one after another. From the feedback of users, we know that after the operation of the ozone disinfection system (JZCF-B series), it really replaced the old disinfection process method and achieved good process and economic results. In order to meet the needs of customers in the cosmetics industry, our company constantly explores new process routes and supporting methods to reduce costs, reduce investment costs, and better serve customers.
