Preservation of the environment is simple - the new century food packaging new fashion

With the progress of society and the development of science and technology, the food manufacturing industry has stimulated people's desire for consumption, broadened the market for products, and continuously expanded the development and improvement of food packaging, so that food packaging has shown obvious characteristics of the times. Nowadays, while continuing to pursue pleasing, elegant and elegant artistic effects, functionalization, environmental protection, and facilitation have gradually become the mainstream of international food packaging, and have achieved a new leap in technology.
Protecting the quality of foods and maintaining the freshness of foods are the most important and basic functions of food packaging. Therefore, the pursuit of increasingly perfect preservation has become the preferred target for 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. 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 ethylene and carbon dioxide gas released from vegetables and fruits, inhibit the decomposition of chlorophyll, and maintain the freshness. Currently, this technology has been applied in Japan. The United States also introduced a new fruit preservation bag made of natural activated clay and polyethylene plastic. This new type of storage bag is like a very fine screen, gas and water vapor can flow through the bag. Tests have shown that when fresh fruits and vegetables are packaged in new packaging bags, the fresh-keeping period can be more than doubled, and the packaging bags can be reused for recycling. The latest preservation technology is the use of oxygen-removing materials developed by the UK and Germany on the inner walls of containers and lids to “eat” the excess oxygen inside the container through these oxygen scavenging materials to achieve freshness preservation and prolong the shelf life of products. purpose.
When people pay great attention to the ecological environment, the green packaging of food has become an extremely important marketing tool and means. Therefore, the food packaging industry has taken measures to promote the ecological and environmental protection of food packaging. The developed countries are also using it. High-tech has opened up a new world for the green packaging of the domestic food industry. At the same time, all countries in the world are reducing, reusing, and degrading their targets and means for eco-friendly packaging. The principle of reduction is: if the product can not be packaged, it should not be packaged, and the necessary packaging should be simplified as much as possible to minimize the use of materials. 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 is manifested in: on the one hand, it actively develops new reusable new packaging materials, and on the other hand, it strives to use a single type of packaging material in packaging design, does not use heterogeneous or composite materials, and reduces 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 disposal, 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 more complex and rapid. It is stipulated that disposable plastic packaging materials should be marked with material names and classification codes. The degradable aspect is manifested in the active promotion of paper packaging and the development of alternative materials that are easily degradable. At present, many developed countries have already achieved 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. In the United States, soybean protein packaging film is made from soybean protein by adding enzymes and other materials. This kind of packaging can make foods keep moisture and prevent oxygen from entering. At the same time, it can also be steamed with food to avoid secondary pollution of food. In view of the unparalleled advantages of plastic materials in food packaging, developed countries are making great efforts to develop biodegradable plastic packaging materials to replace traditional plastic products, and many products have been successfully put into use, achieving a breakthrough and leap in packaging materials. In order to solve the "white pollution" bring hope.
In the fast-paced society today, the convenience of opening food packaging is very important. At the same time, many creative designs have been created. Many countries in Europe and the United States have focused their efforts on plastic packaging. One of the important trends is to use glass bottles instead of glass bottles when packaging foods such as high-quality soups, pasta sauces, jams, and jellies. Packaging cans made of (PET) materials, these cans are safe to use and won't break, and at the same time they have molded handles on the sides for easy access. The United Kingdom and the United States have made creative improvements on the packaging, introducing a series of designs that are beneficial to users, such as imitating baby bottle-style caps on beverages and mineral water bottles, and using plastic-made switch-dispensers on milk cartons. The 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, consumption, and export. However, for a long time, the packaging technology and technology of the food industry in China have lagged behind. In view of this, we must pay attention to catching new trends and development trends in food packaging in the international market, increase technological investment, and improve food products. Packaging materials, technologies and processes to improve the ability of China's food export earnings. (Lin Gao Peng) (From "China Packaging News")
