Assembled antibacterial technology using antibacterial BOPP film (on)

With the development of society and the improvement of people’s living standards, a healthy, comfortable and hygienic living environment has increasingly become the goal pursued by people. Various bacteria, molds, viruses and other microorganisms that endanger human health have caused people’s great attention, especially The occurrence of the SARS virus epidemic this year will change the people’s concept of life. The pursuit of antimicrobial and anti-mildew products for daily use has become a new trend. This article describes a new type of domestic antibacterial material - antibacterial biaxially oriented polypropylene film (referred to as antibacterial BOPP film).
Since BOPP film was introduced into China in the 1980s, it has been widely used in food, medicine, agricultural and sideline products, beverages and other packaging fields. However, people are only concerned about the transparency, barrier and beautiful appearance of BOPP film, and ignore its hygiene requirements. Using a new generation of molecular assembly antibacterial technology with complete intellectual property rights, a new generation of functional, antibacterial, anti-mold and anti-virus anti-bacterial BOPP film has been developed on the BOPP biaxially oriented film-making unit.
A new generation of antibacterial BOPP film is the use of molecular assembly of antibacterial technology, in the basic resin of the BOPP film on the polypropylene molecule, the assembly of the preferred antibacterial functional group made of polypropylene antibacterial masterbatch.
In the manufacture of BOPP film, in the film surface or in contact with the surface layer of food, medicine, beverages, the above masterbatch is added to the auxiliary material in a certain proportion, and is made by biaxial stretching of the extruder, thus giving the BOPP film contact with food and beverage, The surface of the drug has an antiseptic effect.
Antibacterial BOPP film, in addition to the performance of ordinary film, also has the following significant features:
(1) Efficient and broad-spectrum antimicrobial activity. Since the antibacterial masterbatch has good compatibility with the polypropylene resin, and the assembly rate of the antibacterial functional group is controlled through the adjustment of the process, the antibacterial range can be distributed on the nanoscale of the antibacterial film layer, thereby making it highly efficient. The antibacterial effect is extremely excellent in inhibiting various harmful bacteria and molds. Select common E. coli and golden yellow grape spheres that are harmful to humans and food, and refer to FZ/T01021-92 (Test method for antibacterial properties of fabrics), Ministry of Health of the People's Republic of China in 1999 (Disinfection Technical Specification———Antibacterial test The Quinn test method in Japan and the antibacterial material (product) membrane coating method developed by the Japan Food Analysis Center were tested by the Guangdong Center for Microbiology Analysis and Testing. The antibacterial rates of the above two strains were 99.92% and 99 respectively. .99%. (Unfinished)
