Ozone generator for packaging and laminating

The function of commodity packaging in modern marketing is paid more and more attention by commodity manufacturers. At present, the means of commodity packaging are diversified, and the packaging technology is also complex. Packaging and film covering is an essential process in the packaging industry. The viscosity and firmness of packaging and film covering are also the decisive factors to ensure the preservation and quality of the goods in the packaging bags (boxes, boxes, etc.).

Lamination is the coating of adhesive after the plastic film, and paper printing by heating, pressure after bonding together, the formation of paper plastic products. As a result of a thin and transparent plastic film on the surface of the coated printed matter, the surface is smoother and brighter, which not only improves the glossiness and fastness of the printed matter, but also prolongs the service life of the printed matter. At the same time, the plastic film also plays the role of waterproof, antifouling, wear-resistant, folding resistant, chemical corrosion resistant and other protection. If transparent bright film is used to cover the film, the printing image and text color of the coated product is more vivid and full of three-dimensional sense, especially suitable for the packaging of green food and other commodities, which can cause people's appetite and consumption desire. If we use matte film coating, the coated products will give consumers a noble and elegant feeling. Therefore, the coated packaging printing products can significantly improve the quality and added value of commodity packaging. At present, the common coated packaging products are cartons, cartons, handbags, fertilizer bags, seed bags, stickers and so on.

Theoretically, in order to obtain good printability, the surface tension of substrate should be higher than that of printing ink. Common PP and PE films are non-polar polymer materials, which have stable chemical properties and low surface tension. In addition, due to the influence of opening agent, antistatic agent and anti-aging agent added in the synthesis of resin, it is difficult to bond with ink. This makes many packaging and film coating manufacturers increase ozone application technology in the later stage of the process.

According to the chemical principle of strong oxidation of ozone, ozone is introduced into the packaging PE film and paper at the moment of lamination to oxidize the rough surface of the film so as to effectively increase the adhesion of the film and improve the composite efficiency. In the process of cooperation with several packaging and laminating units, Jinan Sankang found that ozone generation technology has the following advantages in the packaging and laminating industry:

① The paper can be protected by using the ozone generator to cover the film. Paper covered by ozone generator can extend its cover life, especially for textbooks.

② After coating with ozone generator, the marks are not easy to be damaged. The film covering of ozone generator can protect the cover of color picture and text, but it is not easy to be worn.

③ The use of ozone generator film production capacity. The production cost of the ozone generator covered with film is low, the profit is large, and the enterprise can benefit.

With the development of science and technology, the application technology of packaging film covered ozone technology is becoming more and more mature, and the scope of ozone application technology will become more and more extensive.
