With the progress of society and the development of science and technology, the food manufacturing industry has continuously increased the development and improvement of food packaging to stimulate people's consumption desire, expand product sales, and make food packaging show obvious characteristics of the times. Nowadays, while continuing to pursue pleasing, noble and elegant artistic effects, functionalization, environmental protection and simplification have gradually become the mainstream trend of international food packaging, and have achieved a new leap in technology

the most important and basic function of food packaging is to protect the quality of food and maintain the freshness of food. Therefore, the pursuit of increasingly perfect preservation function has become the first goal of food packaging. At present, aseptic fresh-keeping packaging is very popular in the food manufacturing industry of all countries in the world, especially in developed countries. One third of beverages in Britain, Germany, France and other countries have used aseptic packaging. Its application is not only limited to fruit juice and fruit juice beverages, but also used to package milk, mineral water and grape wine

a mineral concentrate developed in Japan recently with calcium phosphate as raw material seeps into absorbent paper bags, and vegetables, fruits and other foods are transported into this paper packaging material. Fruits and vegetables can get nutrition from the mineral concentrate. Calcium phosphate can also absorb ethylene gas and carbon dioxide released by vegetables and fruits, inhibit the decomposition of chlorophyll, and maintain freshness, At present, this technology has been applied to low carbon steel in Japan. The United States has also launched a new fruit preservation bag made of natural activated clay and polyethylene plastic. This new type of preservation bag is like a very fine sieve. Gas and water touch a series of thermoforming, folding and bonding operations, and steam can flow through the bag

the test shows that the fresh-keeping period of fruits and vegetables packed in new packaging bags can be more than doubled, and the packaging bags can be reused for recycling. The latest fresh-keeping technology is developed by Britain and Germany. Deoxidizing materials are used on the inner walls of containers and lids to "eat" the excess oxygen inside containers through these deoxidizing materials, so as to achieve fresh-keeping and extend the shelf life of products

today, when people pay great attention to the ecological environment, the green packaging of food has become a very important marketing tool and means. Therefore, the food packaging industry has taken measures to promote the ecological and environmental protection of food packaging. Developed countries do not hesitate to use high and new technology to create a Xintiandi for the green packaging of their food industry. At the same time, all countries in the world have reduced, reused, recycled Degradability is the goal and means of eco-friendly packaging. The principle of reduction is that if the product can not be packaged, it should not be packaged. The necessary packaging should also be simplified as far as possible to minimize the amount of materials used

in Japan, except tomatoes, strawberries, peaches and other melons and fruits, the vast majority of vegetables and fruits are not sold and packaged, and only fresh-keeping paper with special functions is used to prevent moisture penetration. Reuse and recycling is manifested in that, on the one hand, it has actively researched and formed a certain production scope system, which is a new and reusable packaging material. On the other hand, it strives to select a single kind of packaging material in packaging design, without using heterogeneous or composite materials, reduce the combination between group packaging materials, or improve packaging design technology, so that consumers can easily remove the packaging and put it separately for treatment according to environmental protection requirements, It is conducive to the separation operation of packaging waste recycling. In order to make it easier for consumers to identify the nature of plastic packaging materials and make the recycling of waste products easier and faster, the United States stipulates that disposable plastic packaging materials should be marked with material names and classification codes. In terms of solvability, it is actively promoted to avoid accidents and degraded performance caused by a large amount of dust inhalation into the unit Paper packaging and the development of degradable alternative materials

at present, many developed countries have achieved the modernization of the packaging paper mold industry and the widespread promotion of paper packaging materials. For example, in Japan, even edible oil is mostly sold in paper packaging. The United States uses soybean protein to make soybean protein packaging film after adding enzymes and other materials. This packaging can keep food moisture and prevent oxygen from entering. At the same time, it can also be cooked and eaten with food to avoid secondary pollution of food. In view of the unparalleled position and advantages of plastic materials in food packaging, developed countries are vigorously developing degradable plastic packaging materials to replace traditional plastic products, and many products have been successfully put into use, realizing the breakthrough and leap of packaging materials, and bringing infinite hope to solve the "white pollution"

in today's fast-paced society, the convenience of opening food packaging is very important, and many creative designs have also been produced. Many European and American countries' improvement efforts in this regard are mainly focused on plastic packaging. One of the important trends is that when packaging food such as high-quality soup, pasta jam, jam and jelly, glass bottles are no longer used, but packaging cans made of (PET) materials are used instead. These packaging cans are safe to use and will not be broken. At the same time, in order to facilitate access, the sides of these packaging cans are also equipped with molded handles. Britain and the United States and other countries have made creative improvements in packaging, and introduced a series of designs that are conducive to users, such as caps that imitate the style of baby bottles on the bottles of beverages and mineral water, switch type pouring devices made of plastic are designed on the milk boxes, and switches with large openings are installed on the upper ends of beer and beverage cans, so that users can drink as much as possible

China is a big country in food production and export, but for a long time, the packaging technology and process of China's food industry have lagged behind. In view of this, we must pay attention to capture the dynamic trend of food packaging in the international market, increase scientific and technological investment, improve the technology and process of food packaging, and improve the export foreign exchange earning capacity of China's food
