Green food with green packaging

Recently, I walked a few supermarkets and vegetable markets, and I saw a lot of signs hanging on the shelves with green food, especially fresh semi-finished vegetables, fresh fruits, and rice, millet, and flour. The author asked several salespersons: What is green food? Some say pollution-free, chemical-free; some say safe, high-quality nutritious foods. The author carefully read the green food, but found that its packaging is not a green package, there is an urgent problem that can not be ignored.
What is green packaging? According to experts, it refers to packaging that is harmless to the ecological environment and human health, has no environmental pollution, can be reused, recycled, and reused, and can promote sustainable development. Therefore, the developed countries in the world have determined that the packaging should meet the "4R+1D" principle, namely low consumption, development of new green materials, reuse, recycling and degradability. Experts predict that green food will dominate the world market in the next 10 years. Green food must have green packaging, and active research and development of "green packaging" is the inevitable choice for the packaging industry to face WTO in the new century.
According to the statistics of the Heilongjiang Provincial Green Food Office, there were 210 products with the right to use green food signs in the province last year, including 201 A-class and 9 AA-class. The annual market sales reached 3.057 billion yuan, showing that green food has a good development prospect. However, green food is hardly seen to have a matching green packaging. Most semi-finished vegetables and fresh fruits are packed in disposable foam plastic trays (boxes) and outside in transparent plastics. Green rice, green corn husks, and millet are packaged in plastic woven bags.
Green foods do not have green packaging, which is not conducive to freshness or sanitation. It neither attracts customers to purchase nor adds value to green foods. It cannot protect green foods but also causes losses. Therefore, all walks of life generally call for: Green food must have green packaging. It is well-known that good green packaging has become almost a pass for green food among consumers. It shapes green foods into good brands, guarantees the quality of green foods, and becomes the golden key for bringing green foods to the international market.
Protecting the quality of green foods and maintaining the freshness of green foods are the basic functions of green packaging. Therefore, green sterile fresh-keeping packaging is the preferred goal of green food packaging. It is understood that Britain, Germany, France, etc. have already used 1/3 of their beverages in aseptic packaging. Now they have been used to package fruit juices, milk, and mineral water. The Japanese research department has recently developed a mineral concentrate containing calcium phosphate as a raw material to infiltrate absorbent paper bags, and put green foods in such packages. Green foods can be supplied with nutrients from mineral concentrates to provide good preservation effects. .
Fresh-keeping bags are the best packaging for green fruits and vegetables. The Harbin North Preservation Institute has developed a fruit and vegetable fresh-keeping packaging bag. Green fruits and vegetables can be stored for 60 to 80 days at a certain temperature. And fresh-keeping bags can be reused for recycling. The latest preservation technology is the use of oxygen-removing materials developed by the United Kingdom and Germany on the inner walls of containers and lids to “eat” the excess oxygen inside the container through these oxygen-removing materials to achieve freshness preservation and extend the shelf life of green foods. purpose.
Many provinces and cities have realized the modernization of the packaging paper mold industry and the general promotion of paper packaging materials on green food packaging. The grain packaging machine developed by Harbin Kehua New Technology Development Co., Ltd. directly packs quantitative grain in paper bags and is popular with users.
There are 15 decomposing lunch box manufacturers in the province. They produce pulp molding, paperboard coating, plant fiber, rice flour biodegradable plastic tableware and trays. They are ideal green food packaging and can completely replace one time. Foam plastic tray (box). It can solve white pollution and protect the ecological environment.
An edible packaging is now emerging, which is a good way to solve the contradiction between food packaging waste and environmental protection. Its goal is to make a packaging film that does not affect the flavor of green foods. Has been developed and produced a variety of.
Green foods must have green packaging. This has become the new style of green food packaging in the new century and has become the mainstream of packaging. The government environmental protection department clearly stipulates that the “four-in-one” sign should be on the outer package of green food: green food sign, green food text, code and laser anti-counterfeiting label, and certification unit. At the same time, it is reported that natural foods do not equal green foods. When shopping, you must pay attention to identify the outer package "green card." (Guo Yi) (From "China Packaging News")
