[China Packaging Network News] Packaging machinery is a machine that guarantees the production of goods. Because it concerns the production of enterprises, consumers are particularly concerned about the quality of packaging machinery. Because a good quality packaging machine will not cause too much trouble during use, it will not cause losses to the company when it is used. Therefore, when people purchase packaging machinery, they first throw away other types of factors such as performance and functionality, and give priority to products with better quality. There are 12 types of packaging machinery, namely, beer, beverage filling machinery, sealing machinery, wrapping machinery, vacuum packaging machinery, bag forming filling and packaging machinery, strapping packaging machinery, bag filling and sealing packaging machinery, corrugated cardboard and carton processing machinery, metal containers Packaging machinery, plastic container processing machinery, pharmaceutical packaging machinery, printing and packaging machinery.
At present, the R&D of food packaging machinery is moving in the direction of high speed, multi-functionality, and intelligent control to meet market demand. In order to meet the requirements for delivery time and reduce the need for process circulation costs, food packaging machinery in the future is required to be capable of high-speed production. At the same time, for some products, it is also required that the packaging machine and the production machine be connected, and that continuous work or multi-head work mode can also be adopted. In addition, the scrap rate and failure rate must also be reduced so that normal productivity can be improved. The trend is to further intelligentize packaging machinery. Packaging machinery pursues the integration of packaging and processing. There are many new packaging technologies built on new packaging ideas. Packaging new thinking means detaching existing packaging technologies and products, and applying other related technologies to packaging to form new packaging technologies. This includes packaging cutting and forming technology, packaging curing technology, packaging function protection technology, and packaging and processing. Combining technology and packaging function borrowing technology. In addition to the above, there should be some other technologies, such as packaging technology for fresh produce. In addition, with the emergence of new packaging materials, some new changes have also occurred in the packaging process. Such as the emergence of dry stretch film, so that wrapping, shrinkage, banding and other processes into one, the operation is simplified and fast. This kind of packaging and processing integrates many processing technologies and directly uses the packaging mechanism to realize the integration of packaging and processing, making packaging more potential and effective.
The characteristics of vacuum packaging are as follows: 1. Excluding part of the air (oxygen) in the packaging container can effectively prevent food spoilage. 2, the use of barrier (airtight) excellent packaging materials and strict sealing techniques and requirements can effectively prevent the exchange of the contents of the package, you can avoid food weight loss, loss of taste, but also to prevent secondary pollution. 3. The gas inside the vacuum packaging container has been eliminated, which accelerates the conduction of heat, which can increase the heat sterilization efficiency, and also avoids the rupture of the packaging container due to the expansion of the gas during heat sterilization.
China Packaging Network Editor believes that in the food industry, vacuum packaging applications are very common, all kinds of cooked products such as chicken, ham, sausages, etc.; pickled products such as various pickles and soy products, preserved fruit and other foods need to be more fresh More and more vacuum packaging is used. Vacuum-packaged foods have a long shelf life, greatly extending the shelf life of foods.
