With the progress of society and the development of science and technology, while food packaging continues to pursue artistic effects, functionalization, environmental protection, and facilitation have gradually become the mainstream of international food packaging, and a new leap in technology has been achieved. The pursuit of increasingly perfect preservation has become the first goal of food packaging.
At present, aseptic fresh-keeping packaging is extremely popular in the food manufacturing industry in countries all over the world, especially in developed countries. Britain, Germany, France and other countries have already used 1/3 of their beverages in aseptic packaging, and their application is not limited to juices and juice drinks. It is also used to package milk, mineral water and wine. In Japan, a mineral concentrate containing calcium phosphate as a raw material has recently been infiltrated into absorbent paper bags. Vegetables, fruits and other foods are transported in such paper packaging materials. Fruits and vegetables can be supplied with nutrients from mineral concentrates. Calcium phosphate is also available. It can absorb the ethylene gas and carbon dioxide released from fruits and vegetables, inhibit the decomposition of chlorophyll, and maintain the freshness. Currently, this technology has been applied in Japan. The United States also introduced a new type of fruit fresh-keeping bags made of natural activated clay and polyethylene plastic. This new type of fresh-keeping bag is like a very fine sieve. Gas and water vapor can flow through the bags. Tests have shown that when fresh fruits and vegetables are packaged in new bags, the freshness can be more than doubled, and the bags can be reused for recycling. The latest preservation technology is developed by the United Kingdom and Germany to use oxygen-removing materials on the inner walls of containers and lids to "eat" the excess oxygen inside the container through these oxygen-removing materials to achieve preservation and prolong the shelf life of products.
The green packaging of food has become a very important marketing tool and means.
The food packaging industry has taken measures to promote the ecological protection of food packaging. Developed countries have not hesitate to use high technology to create a new world for the green packaging of the domestic food industry. At the same time, all countries in the world have reduced, reused, and degraded their products as ecologically friendly. Packaging goals and means. In Japan, with the exception of tomatoes, strawberries, and peaches, the vast majority of fruits and vegetables are not sold and packaged, and only fresh-keeping papers with special functions are used to prevent moisture penetration. Reuse recovery performance, on the one hand, actively develop new reusable new packaging materials, on the other hand, in the packaging design, strive to use a single type of packaging materials, do not use heterogeneous or composite materials, reduce the combination of group packaging materials, Or improve the packaging design technology so that consumers can easily dismantle the packaging according to environmental protection requirements and put them separately for processing, which will facilitate the separation of packaging wastes. In order to make it easy for consumers to identify the nature of plastic packaging materials, the United States makes waste recycling easier and faster. It is required that the disposable plastic packaging materials should be marked with material names and classification codes. At present, many developed countries have realized the modernization of the packaging paper mold industry and the general promotion of paper packaging materials. For example, even Japanese cooking oil is sold in paper packaging. The United States uses soybean protein to be processed into soybeans by adding enzymes and other materials to make soybeans. Protein packaging film can also be cooked and eaten with food to avoid secondary contamination of food. In view of the unparalleled superiority of plastic materials in food packaging, developed countries are making great efforts to develop biodegradable plastic packaging materials to replace traditional plastic products. Many products have been successfully put into use and achieved a breakthrough in packaging materials. "White pollution" brings unlimited hope.
The ease with which food packaging is opened will be even more important, and many creative designs will be produced. In many countries in Europe and the United States, improvements in this area focus on plastic packaging. One of the important trends is that when packaging foods such as high-quality soups, pasta sauces, jams, and jellies, glass bottles are no longer used. Packaging cans made from PET materials, these cans are safe to use and will not break, but also have molded handles on the sides. In countries such as Britain and the United States, creative improvements have been made on packaging, and a series of designs that are beneficial to users have been introduced, such as imitating baby bottle-style lids on bottles of beverages and mineral water, and using plastic-made switch-style inverted milk bottles. Outlet device, beer and beverage cans are equipped with large mouth switches on the top to allow users to drink as much as possible.
China is a big country for food production and export, but for a long time, the packaging technology and technology of the food industry in China have lagged behind. Experts suggest that companies must pay attention to capturing the development trend of food packaging in the international market, increase investment in science and technology, improve the technology and technology of food packaging, and improve China's ability to export foreign currency through exports.
