core tip: at present, there are still technical problems in the process of antibacterial packaging, in addition, it is also very expensive. Kay Cooksey, a contributor to packaging world magazine and an environmental friendly material such as Clemson, is mainly composed of plant cellulose nanocrystals. In a recent academic angle column, University Professor Kay Cooksey pointed out that the market application of antibacterial packaging needs to improve its quality from the laboratory level to the product level

[China Packaging News] at present, there are still technical problems in the process of antibacterial packaging. In addition, it is also very expensive. Kay Cooksey, a contributor to packaging world magazine and professor of Clemson University, pointed out in the recent academic angle column that the market application of antibacterial packaging needs to improve its quality from the laboratory level to the product level

nowadays, we can see antibacterial packaging applied to smoked salmon products in the Turkish market. Unfortunately, there is no certification system for salmon sales owners at present, so the views of product brand owners will not appear in the following. However, the application of antibacterial packaging is worth mentioning, although the only explanation comes from two major suppliers. One is Erze ambalaj, a Turkish packaging material manufacturer, which is the largest foam material manufacturer in Europe. It produces 60 tons of polystyrene per day in its two plants. The other is an antibacterial resin supplier: parx plastics and additives

Founded in 2012, parx is headquartered in the Netherlands, and its research center and production equipment are located in Italy. The company claims that its sanipolymers ™ Technology represents "a revolutionary biocompatibility technology used to produce antibacterial plastics that can reduce 99% of bacteria within 24 hours." The company's technology is based on bionics, which means it comes from nature. As the company official said, "nature can do magical things, so why not let nature bring us sustainable development solutions?"

zinc is the main mineral in food and is also very important for our daily diet. Zinc is an important component of sanipolymers products of parx company. The company puts polystyrene particles in a reactor to make them have antibacterial properties "under very special conditions". The company claims that the products produced with sanipolymers technology have obtained anti-corrosion and antibacterial properties, and this effect has been confirmed by ISO 22196 and JIS 2801 standard tests

parx co-founder Michael van der Jagt explains why parx is different: "The other way to make plastics have antibacterial properties is to use some toxins or other harmful substances. Heavy metals, such as silver, or some chemicals, such as triclosan, and some nano materials, such as nano silver, emboss the hard phase of the sample. After treatment with these substances, some active substances will leach from the plastic parking switch and then attack bacteria. However, zinc is the most important element in human body Minerals needed by the day. This element is non-toxic and completely harmless to human body. Adding zinc into plastics will not cause any migration. Therefore, it is' gras' (generally considered harmless), and has certain nutrition, and there will be no migration. "

the outer package used for smoked salmon products is a box made of pet (polyethylene terephthalate) material, and the inner package is a box made of EPS (expandable polystyrene) material produced by Erze ambalaj company. The inner foam box has antibacterial properties. Erze ambalaj company conducts direct gas extrusion operation on the hot processed box, which is used to produce foam materials. 3. After the sample is crushed. A small amount of sanipolymer is added to ordinary polystyrene particles to obtain a mixed packaging material
