Modern food puts forward higher requirements for packaging

in recent 50 years, the sales of food in China has gradually shifted from retail stores and specialty stores to self selected malls and large department stores. In order to adapt to this situation, food packaging is on demand. Through the confusion of patented food packaging products, it is not difficult to see the dynamics and trends of China's food packaging industry

from the State Intellectual Property Office of the people's Republic of China since 1985, there are 104 food packaging patents

and 317 aerogel gel patents, including 57 invention patents, 176 utility model patents, and 10084 appearance patents, which have become the key to winning the market competition. In, the number of food packaging patents applied for was 40, with 10 invention patents applied for the most in 2000, followed by 1998 and 1995, with an average of 5 invention patents applied for every year. In general, the number of food packaging invention patents applied for is in a wavy distribution, and with the continuous improvement of packaging equipment, 3 The tensile force range of experimental materials tends to increase

and have developed steadily in recent years. Invention patents and appearance patents reached the peak in 1999, and the three kinds of patents were decreasing after 2000. In general, invention patents are the least, fluctuating within 10 every year; Utility model patents have gradually increased in recent years; After a slow rise, appearance patents have a significant downward trend

the invention of food packaging is not satisfactory

so far, the invention patents of food packaging can be roughly divided into five categories according to the content: the invention of food packaging equipment, packaging materials, packaging methods, packaging auxiliary materials and packaging containers. The proportion of these five types of patents, and the invention patents of food packaging materials and packaging containers occupy an advantage in food packaging patents. The invention of packaging equipment is the least, which may be due to the large investment, long time-consuming and unstable income of the invention of packaging equipment, so there is less research in this direction

of course, the research hotspots in a certain field may be different in different periods. The proportion of these five invention patents has not changed significantly in recent years. It has always been the focus of food packaging invention patents because there are many patents applied for the invention of packaging materials and packaging containers. There are fewer invention patents applied for packaging equipment, packaging methods and packaging auxiliary materials. In the past three years, no invention patents have been applied for packaging methods, and the invention of packaged finished product containers is also less than that in the past years

utility models and appearance patents are better

utility model patents for food packaging involve a wide range of contents and fields. However, with the continuous development of science and technology, it has attracted more and more attention, and the development prospect is also considerable. The number of appearance patents for food packaging occupies an absolute advantage in food packaging patents. According to the content, utility model patents and appearance patents can be roughly divided into five kinds: packaging bags, packaging boxes, packaging cans, packaging containers and packaging films. Utility model patents and appearance patents of food packaging bags account for the vast majority of the total appearance patents of food packaging, which is inseparable from the overwhelming market share of packaged food. Food packaging film occupies a small proportion of utility model patents and appearance patents, mainly because of the practicality of packaging film and the role of assisting other packaging containers in non independent packaging. Food packaging cans are also less, because they are mainly aimed at liquid food, so they occupy less market

for packaging patents, among the three patents of packaging invention patents, utility model patents and appearance patents

, the proportion of food packaging patents in packaging patents is relatively small; For food patents, the proportion of food packaging patents in invention patents and utility model patents is also small, but the proportion of appearance patents is as high as 87%, which shows that most of the applied appearance patents of food patents are in the form of food packaging patents

with the further adjustment of the product structure and the upgrading of products in China's food industry, new requirements are also put forward for packaging. First, food quality and safety assurance, more stringent requirements on packaging technology and packaging materials; Second, the filling and packaging forms, speeds and specifications are more diversified, and the packaging materials and containers are standardized, serialized and generalized; Third, higher requirements for packaging decoration and packaging image

fourth, there should be new breakthroughs in the anti-counterfeiting of packaging; Fifth, try to reduce packaging costs

modern food packaging is the product of modern food production, circulation and consumption, and must adapt to the circulation conditions of modern food products and the development of the sales market. Therefore, automation, mechanization and environmental protection are the irreversible development trend of food packaging, which cannot have signs of slippage
