core tip: as for the packaging materials on the market at present, the types of packaging materials are complex, and their performance and uses are also different. In such an environment, enterprises that need food machinery manufacturing should study and master the packaging performance and use conditions of various packaging materials. The external packaging of food can not only protect the flavor and quality of food, but also reflect the packaging materials that match its commodity value, but sometimes the same kind of products can use different packaging methods to achieve the same effect

[China Packaging News] as far as the packaging materials on the market at present are concerned, the types of packaging materials are complex, and their performances and uses are also different. In such an environment, enterprises that need food machinery manufacturing should study and master the packaging performance and use conditions of various packaging materials. The external packaging of food can not only protect the flavor and quality of food, but also reflect the matching with its commodity value. An interview was conducted with the packaging materials of the head of the product quality supervision and testing center published by the General Administration, but sometimes different packaging methods can be used for the same kind of products to achieve the same effect

is your food safe? First, let's see whether the stable packaging of food is safe. In fact, whether at home or in the supermarket, we can see some beautifully designed food packaging bags everywhere. Food packaging bag is actually food clothes. It not only plays a role in protecting food, but also closely related to food safety

in terms of the current domestic food packaging situation, the form is not optimistic. Some people believe that the external packaging of food is an invisible additive. The external packaging of many foods in life may contain toxic and harmful substances, but because the release and migration of these harmful substances are mostly invisible and chronic, and often undetected. From the perspective of food safety, the harmful substances in the external packaging of food will directly threaten the safety of food

for example, for foods that are easy to oxidize, vacuum or inflatable packaging can be used, and deoxidizer can also be used for packaging. The selection of packaging technology is closely related to the selection of packaging materials, which is also closely related to many factors such as the market positioning of packaged food

as far as the packaging materials on the market at present are concerned, the types of packaging materials are complex, and their performances and uses are also different. In such an environment, enterprises that need food machinery manufacturing should study and master the packaging materials. Overseas researchers are trying to use a variety of agricultural wastes such as hibiscus, banana, bamboo, sugarcane stalk fiber and coffee bean shell to make degradable plastic packaging performance and use conditions. The external packaging of food can not only protect the flavor and quality of food, but also reflect the packaging materials that match its commodity value. However, sometimes the same kind of products can be used for the transformation and upgrading of enterprises. We can no longer wait and see, and different packaging methods can achieve the same effect. According to the protective requirements of food, estimate the packaging cost, packaging volume and other aspects to carry out reasonable packaging design, try to achieve reasonable packaging structure, save materials, save transportation space and conform to the trend of the times, and avoid excessive packaging and deceptive packaging. The market positioning of commodities, the mode of transportation and the climatic and geographical conditions of the circulation area are the factors that must be considered in the design of food packaging. For food packaging, the change of climatic conditions in commodity circulation areas is of great importance, because temperature has a great impact on the chemical changes of internal components of food, the barrier of food microorganisms and their packaging materials

modern food packaging should not only focus on the development, research and application of new packaging materials, as well as higher scientific and technological content, make use of the characteristics of new materials such as delicacy, smoothness and flexibility to serve the best effect of packaging food, but also constantly promote the development of packaging machinery industry, automate, systematize and integrate the process flow with computers, reduce the waste rate of food packaging processing, and make full use of resources

in the food industry chain, some links of food packaging machinery consume high energy, waste emissions are large, and production costs are high. The traditional food packaging machinery design rarely considers the relationship between environmental attributes and food safety, and its industrial chain generally only considers the links of design, manufacturing and use. On the contrary, the design of food packaging machinery in the new era should not only consider conventional production conditions, but also consider scrapping, disposal and other links. Therefore, it is necessary to formulate green design standards for food packaging machinery, realize reasonable matching of food packaging machinery, effectively use resources, protect the environment, and improve the quality and safety of processed food

with the strengthening of people's awareness of environmental protection and attention to health, green food will become the mainstream. In foreign countries, it is the mainstream to improve the green performance of food and packaging machinery through technological research and development. It can be seen that the future development trend of domestic food packaging machinery will be energy-saving and environmental protection
