Current situation of the latest BOPP antibacterial

  • Detail

The new BOPP antibacterial film is now expected to be available to the public at the end of May. The core component of the antibacterial material is antibacterial agent, but whether it is natural antibacterial agent, organic antibacterial agent or inorganic antibacterial agent, it has its own unavoidable defects. There is no doubt that natural antibacterial agents are relatively environmentally friendly and their safety performance is relatively guaranteed, but due to the limitations of their raw material processing conditions, there is no condition to realize large-scale market-oriented production at present. Although organic antibacterial agents have strong bactericidal power and plastic is the greatest invention in the 21st century, they have poor heat resistance. The most important thing is that they have certain toxicity and short service life. Inorganic antibacterial agent just solves the problem of organic antibacterial agent, but the higher price brings the higher cost, and the slow antibacterial effect also affects its promotion and application in the market

the birth of some new BOPP antibacterial films has well filled the market gap of accelerating the development of "integrated design and manufacturing" of cr929 aircraft fuselage and tail structure. They use molecular assembly antibacterial technology to assemble optimized antibacterial functional groups on the molecular chain of the matrix resin, which have high-efficiency and broad-spectrum antibacterial activity, are safe and non-toxic to human body, and have good heat resistance, so as to obtain antibacterial masterbatches. It not only overcomes the defects of common organic antibacterial agents, such as heat resistance, poor compatibility with matrix, poor immersion and washing resistance, and poor safety performance of exudates, but also has the advantages of high efficiency, broad spectrum, safety, non toxicity, long-lasting antibacterial effect, excellent thermal stability, good compatibility with resin, good processing performance and so on. Although its pure packaging cost will rise slightly due to the application of these new technologies and processes, its good performance advantages ensure the extension of the shelf life of the packaging materials, thus driving the corresponding extension of the product sales period, and bringing more profit opportunities to the product manufacturers. In this way, the comprehensive cost will not increase but decrease

however, it should be admitted that at present, such antibacterial films are not widely used in the domestic market, and there are many reasons. Although SARS has temporarily aroused people's awareness of fighting bacteria, it is still very weak compared with overseas countries, which are relatively mature. Some data show that in foreign countries, especially in developed countries such as Europe, America and Japan, the market application of antibacterial film has exceeded 50% in the fields of food, drugs and other fields that attach importance to safety packaging, but it is almost a blank in China. However, this does not mean that our packaging does not need antibacterial film. On the contrary, behind the blank is a huge market. Some packaging material manufacturers have begun to take positive actions to drive the development of this market through process improvement and cost reduction
