At the Chinaplas 2017 exhibition in Guangzhou, many new packaging materials, new technologies and new applications in the plastics industry were unveiled. Among them, one company surprised Xiaobian: the core area of ​​their booth is surrounded by several giant electronic screens. The audience can interact with the electronic exhibits. This article will introduce you to the packaging requirements of metal packaging materials.
The metal materials used in current food packaging include iron, aluminum, stainless steel, and the like. The packaging material can use metal, because the metal has better ductility and is more convenient to process. The outer packaging formed by metal has better protection for the food inside, and the metal is easy to package and thus can be promoted.
However, metal is good for paper, glass and ceramics, but the price is relatively high and the packaging cost is not cheap. Moreover, the chemical nature of the metal is relatively active, it is oxidized and eroded in the air, and it is easy to chemically react with foods containing strong acidity and alkalinity, thereby polluting food. Therefore, at present, although metal can be used widely and has an important position, its use is limited, and it is generally used for canned packaging.
The garbage of the packaging materials of life shall be bagged, stacked at a fixed point, and handed over to the sanitation department for unified disposal; the polystyrene particles, scraps and non-conforming product temporary waste scattered during transportation shall be collected by the production staff and recycled to the temporary waste collection site again. Utilization, the impact is not great. Dangerous solid waste is mainly used equipment waste oil and hydraulic oil. It is collected and recycled by the production staff to the temporary storage place of dangerous waste. The external environment will be less affected after being disposed of by the relevant qualified units.
