面临我国食品工业大发展的形势和人民对食品现代化的要求,迅速发展食品包装已是当务之急.其中蒸煮食品包装的研制生产是一个重要方面.这种包装是采用塑料、金属箔等材料制成的耐热、隔气、防湿等性能良好的包装袋或容器,在日本和欧美各国发展很快.我国在七十年代末开始立题研制,到1981年开始投放市场.大部分软罐头是采用PET/Al/CPP三层材料复合而成的.软罐头由于它具有体积小、重量轻,便于携带和食用,可缩短杀菌时间等特点,所以可供旅游、军用及野外工作的需要.我国在形成大规模工业化生产上也存在不少问题.主要是目前生产效率低、包装价格偏高.为
Faced with the great development of China’s food industry and the people’s demands for food modernization, the rapid development of food packaging is a top priority, of which the development and production of cooking food packaging is an important aspect of this package is made of plastic, metal foil and other materials Heat-resistant, gas barrier, moisture-proof and other good performance of the bag or container, developed rapidly in Japan and Europe and the United States.China began in the late 1970s the development of legislation, to the market began in 1981. Most soft cans is the use of PET / Al / CPP three-layer composite material made of soft cans because of its small size, light weight, easy to carry and eat, can shorten the sterilization time, so for tourism, military and field work needs .In our country There are also many problems in large-scale industrial production, mainly due to the current low production efficiency and high package prices.
