A few days ago, Numerous University of the Gaming University, the company Eltek, which manufactures lasers, and Elopak, which manufactures carton packs, used industrial UV lasers to pre-press pre-embossed polyethylene and coated aluminum paperboard containers on the inner surface of containers. Bacterial spores kill. Through research, it has been found that using a laser to emit ultraviolet light can quickly and effectively sterilize carton packs. It only takes 5 seconds to completely kill bacterial spores in carton packs, and does not require the use of hydrogen peroxide. Studies have shown that if hydrogen peroxide remains in carton packs for food and beverages, the shelf life of the product will be significantly reduced. Although it is possible to manufacture laser sterilizers in commercial production at present, it is difficult to do so because of excessive costs.
