With the advancement of society and the development of science and technology, while food packaging continues to pursue 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.
-- Pursuing increasingly perfect preservation functions has become the first goal of food packaging.
At present, aseptic packaging is extremely popular in the food manufacturing industry in countries all over the world, especially in developed countries. One third of the beverages in the UK, Germany, France and other countries use aseptic packaging, and its application is not limited to juices and juice drinks, but also Also used to package milk, mineral water and wine. Japan recently developed a mineral concentrate containing calcium phosphate as raw material into the absorbent paper bag. Vegetables, fruits and other foods are transported in this paper packaging material. Fruits and vegetables can be supplied from the mineral concentrate, and the calcium phosphate is also It can absorb ethylene gas and carbon dioxide released from vegetables and fruits, inhibit the decomposition of chlorophyll, and maintain the freshness. This technology has been promoted and applied in Japan. The United States has also introduced a new fruit storage bag made of natural activated clay and polyethylene plastic. This new type of fresh-keeping bag is like a very fine sifting, and gas and moisture can flow through the bag. Tests have shown that the packaging of fruits and vegetables in new packaging bags can more than double the shelf life, and the bags can be reused for recycling. The latest preservation technology is developed by British and German. The deoxidizing material is used on the inner wall of the container and the lid. The oxygen-removing materials are used to "eat" the excess oxygen inside the container to maintain the freshness and extend the shelf life of the product.
-- Green packaging of food has become an extremely important marketing tool and means.
The food packaging industry has taken measures to promote the eco-environmentalization of food packaging. Developed countries have used high technology to create a new world for green packaging in the domestic food industry. At the same time, all countries in the world have reduced, reused and degradable as eco-friendly. The goals and means of packaging. In Japan, except for fruits such as tomatoes, strawberries, and peaches, most vegetables and fruits are not sold and packaged, and only packaging papers with special functions are used to prevent moisture penetration. Reuse recycling is on the one hand, actively developing new reusable new packaging materials, and on the other hand, strives to select a single type of packaging materials in packaging design, without using heterogeneous or composite materials, and reducing the combination of group packaging materials. Or improve the packaging design technology, so that consumers can easily disassemble the packaging according to environmental protection requirements and separate the treatment, which is conducive to the separation of packaging waste recycling. In order to make it easier for consumers to identify the nature of plastic packaging materials, the recycling process of waste products is easier and faster. The disposable plastic packaging materials should be marked with the material name and classification code. At present, many developed countries have realized the modernization of the packaging paper mold industry and the widespread promotion of paper packaging materials. For example, Japanese foods are also mostly sold in paper packaging; the United States uses soybean protein to be processed by adding enzymes and other materials to make soybeans. Protein packaging film can also be cooked together with food to avoid secondary pollution of food. In view of the unparalleled positional 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, achieving breakthroughs in packaging materials, to solve "White pollution" brings infinite hope.
-- The ease with which food packaging is opened will be even more important, as well as many creative designs.
In many countries in Europe and the United States, the improvement work in this area is mainly concentrated on plastic packaging. One of the important trends is to stop using glass bottles when packaging foods such as high-quality soup, pasta sauce, jam and jelly. Cans made of PET materials that are safe to use and not broken, with molded handles on the sides. In the United Kingdom and the United States, creative innovations have been made on the packaging, and a series of user-friendly designs have been introduced, such as simulating baby bottle-style lids on bottles of beverages and mineral waters. The design of the milk cartons is made of plastic switches. Out of the device, the upper end of the beer and beverage cans are equipped with a large-mouth switch cover to allow the user to drink as much as possible.
