〔Abstract〕Introduces the relationship between food green packaging and environmental protection, discusses the selection and application of green food packaging materials, the design of green food packaging, and market value.
Keywords: green food; food green packaging design According to experts, the green food will dominate the world market in the next 10 years, and good green packaging is the green food pass among consumers. It is of great significance for shaping green food brands, ensuring the quality of green foods and maintaining the freshness of green foods. 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’s environmental protection department clearly stipulates that the “four-in-one†sign should be on the outer package of green food, namely, the green food sign, the text of green food, the code and the laser anti-counterfeit label, and the certification unit. After clear packaging, it will facilitate the identification of consumers.
1. Connotation of green packaging and green packaging of food The basic function of green packaging is to protect the quality of green food, maintain the freshness of green food, and harmless to the ecological environment. Recycling or recyclable packaging that promotes sustainable development is international marketing. One of the powerful means. Green food refers to specialized safe, high-quality, nutritious foods. In addition to the external package of the product must comply with the national food label green packaging and green food combination constitutes an organism for environmental protection. In the world environment that emphasizes environmental protection, the role of green packaging in sales is increasingly important, and it is increasingly being spurred by consumers from all countries. The important content of the green revolution in the new century is the “green packaging revolution†as an important weight for the new round of market competition. 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 tapping green foods into the international market. It is certain that green packaging products with a strong green atmosphere have strong vitality and competitiveness in the international market, and food packaging is most closely related to human beings. People touch it all the time and it affects people. all. Therefore, green packaging is the common need for human survival and development. The establishment of a green packaging system is of great significance. The development of green packaging is an effective way to promote sustainable development, and it is also an inevitable choice for environmental protection in the 21st century.
2. Selection of green packaging materials for food and green packaging design for food For the green packaging, the State Administration of Technical Supervision of China has established a standard that includes five kinds of products: pulp, paperboard coatings, plant fibers, starch, and biodegradable plastics. In today's situation, countries all over the world are raising "pollution-free, pollution-free" packaging products. These packaging materials require the use of materials, less waste, and can save a lot of resources; waste can be recycled; use burning or other There is no secondary pollution when the method is processed; the waste can be freely decomposed, which is also a few aspects of research in the packaging field in various countries. The ultimate purpose is to make the amount of packaging waste form a very small or minimal environmental pollution. In terms of food packaging, it is a major trend toward green and non-pollution. Green foods must have green packaging. This has become the new fashion of green food packaging in the new century and has become the mainstream of packaging. With regard to the current state of research in China, the following specific food packaging materials are under study or are about to be put into use:
a. Chitosan Edible Packaging Film: This edible packaging solves the conflict between food packaging waste and environmental protection. It is used in candy, preserved fruit, fresh cakes, fresh moon cakes and other aspects.
Production process and features: This packaging film uses shellfish extract chitosan as the main raw material, combining chitosan with lauric acid to produce a uniform edible film, and packaging the peeled fruit with the packaging film and Fruit slices also have a good preservation effect. The chitosan used in this packaging material is a processed product obtained by crushing shellfish shells. As it comes from nature, it has no pollution hazard to the environment, and it has the effect of supplementing trace elements to the human body after consumption. It can be described as a new type of environmentally friendly food packaging. However, it also has its shortcomings, that is, the source of raw materials is limited, it must be close to the coastal areas rich in shellfish.
b. Corn protein packaging film: It is suitable for high-oil, high-permeability, high-oil-containing food packaging, and has a wide range of uses in the fast food industry, fried potato food, moon cake production and other food companies. Corn protein packaging film is mainly used in the inner layer of fast food boxes and other foods with oil.
Production process and features: The film is a paper and corn protein synthesis packaging material, will not be infiltrated by grease, put it into polyester plastic packaging, from the perspective of hygiene, should use the inner packaging film, so the packaging material has a bright future .
c. Soy protein edible packaging film: It is widely used for a variety of ready-to-eat foods.
Production process and features: Mainly uses the remaining material after soybean extract soybean meal to produce, raw material source is broad. In particular, the region rich in soybeans in the North is rich in raw materials. Since soybean residues from soybean meal are used, the price is extremely cheap. The packaging film can not only prevent oxygen from entering, but also maintain moisture, but also ensure the original taste. This kind of edible packaging film is widely used in the food production industry. Most of the sweets and cakes can be used. Because the package has a fresh function and rich raw materials, it has an excellent industrial prospect.
d. Compound edible packaging film: It can be applied to the inner packaging of various ready-to-eat foods.
Production process and features: This kind of protein, fatty acid and starch composite edible packaging film combines different ratios of protein, fatty acid and starch to produce edible films with different physical properties. Because the product can adjust the softness and hardness of the packaging film according to different foods, different types of inner packagings can be formed and there should be a huge market in the food industry.
