[Abstract] Packaging is closely related to human life, while green packaging has the unusual significance of preventing pollution, promoting deepening reforms, and achieving sustainable development for the benefit of future generations. Here are some practical ways to implement green packaging.
Key words: green packaging; environmental destruction; dust storm green packaging, originated in 1987 United Nations Environment and Development Committee's "our common future", also known as environmental packaging, ecological packaging. It refers to the packaging that is harmless to the ecological environment and human health, can be recycled, recycled and used for sustainable development.
1 Destruction of the environment by the packaging industry Packaging plays a role in protecting the goods, facilitating storage and transportation, and propagating and beautifying goods. However, on the other hand, it also has a great destructive effect on the environment.
1.1 Inspiration from sandstorms In recent years, dozens of dust storms have occurred continuously in northern China. These obscure dust storms have filled the sky and covered the sun. They have reduced visibility and caused serious sand loss. Dust storms have repeatedly hit Beijing, almost to Nanjing, and have greatly expanded to the south. This has made the country’s desertification phenomenon more and more serious, causing great concern among experts and senior leaders. The main cause of sandstorms is ecological disasters caused by humans destroying nature and destroying ecological balance. The deforestation directly caused a large loss of water and soil.
Since ancient times, wood has been a major packaging material. In the more than 30 years after the founding of New China, the main raw material for commodity packaging in China was wood, which was processed into wooden boxes, trays, and other packaging materials, or used. Wood, made of cartons, cartons and other packaging. It is not surprising that the ecological disasters that introduced dust storms are certainly a result of the devastating destruction of the ecological environment. The frequent occurrence of dust storms also tells us that the development of processes in the packaging industry has promoted and evaded this ecological disaster.
1.2 Pollution of packaging waste With the expansion of cities and the development of industry, there are more and more urban wastes. Many cities have been surrounded by garbage and have become the most troublesome issue for local governments. In these wastes, packaging waste should be About 40%. Packaging materials that have completed packaging tasks and have no use value, such as plastic film bags, plastic bottles, glass bottles, and metal cans, are the main forces for packaging waste.
In addition, disposable foams have developed rapidly in recent years, and they have been used in a large amount to produce special cushioning packaging such as household appliances and various fragile products, which are very effective, but have been abandoned after use. Dishes such as one-off snack boxes made of such foam are popular all over the country, and are thrown away, causing “white pollution†that affects the national environment.
2 The Significance of Implementing Green Packaging 2.1 Green Packaging is the Fundamental Measure to Prevent Pollution Compared to the end of the treatment, green packaging is a method that can both treat the disease and cure the disease. However, the end of governance has its deficiencies, such as incomplete governance, mostly the transfer of pollutants, can not stop the waste of natural resources, operating costs are higher. The green packaging completely abandons these drawbacks. It strives to eliminate the waste before it is produced, thus eliminating the pollution from the source.
2.2 Achieving Sustainable Development The so-called sustainable development is a development that meets the needs of the present generation without compromising the need for future generations to meet their needs. Its important content is: To protect the environment while developing the economy. The implementation of green packaging can greatly reduce the consumption of resources and waste, rectify the production, restore the damaged environment, and eliminate humanity's current world resource crisis and environmental pollution, thus embarking on the road of sustainable development.
2.3 Promoting deepening reforms of enterprises The implementation of green packaging will inevitably raise new goals for enterprises. It calls for minimizing waste and ultimately achieving waste-free production. To achieve this goal, enterprises must rationally position products, optimize the production process, innovate production processes, strengthen enterprise management, improve the quality of personnel, form a socialized operation network, and maximize economic and social benefits. This is in fact the deepening of reforms. .
2.4 Enze globally, the benefit of children and grandchildren is only one earth. Everyone should love the earth and make humans have a good living environment. Green packaging, as an integral part of sustainable development, has increasingly become a focus of attention in the green wave. It was once hailed as a plastic packaging material that has set off a "packaging revolution." For decades, it has been the limelight in the packaging field. Now it is in the "green wave." The impact has become the target of public criticism." This is because the recovery rate of plastics is very low and the pollution to the environment is the most serious. Plastic waste will exist in nature for decades without degradation, and green packaging will completely change this situation. We also have a clean and clean earth, so that our children and grandchildren have a good living environment.
3 Characteristics of green packaging 3.1 The most use of materials, the least waste of green packaging in advance to meet the protection, convenience, sales and information functions, should be the use of materials with a minimum of civilized and appropriate packaging, the waste generated should also least.
3.2 Recyclable products Packaging and packaging products should be able to be reused, or use recycled waste to produce recycled products, or use their heat energy through incineration. In order to achieve the purpose of reuse. This package neither pollutes the environment nor makes full use of resources.
3.3 Packaging waste is easily degraded In order not to form permanent waste, non-recyclable packaging waste should be easily degraded before it enters nature and achieves the purpose of soil improvement. The degradation should be as short as possible.
3.4 Packaging Waste Non-toxic and harmless packaging materials shall not contain any toxic substances, or their contents shall be controlled below the relevant standards, and no environmental pollution shall be generated during the entire process of manufacturing and processing of packaging products.
4 How to implement green packaging Green packaging is the trend, the direction, and the historical necessity. Then, how can we implement green packaging?
4.1 Reducing packaging waste Each product must be packaged. After the product reaches the user's hands, the packaging is mostly waste. To reduce packaging waste, the amount of packaging materials should be minimized, and reasonable protection should be carried out under the premise of effective product protection. package. For example, thinning of glass and ceramic containers can save materials. All kinds of containers should have large volume in the case of the most use of materials, such as circular containers than elliptical, flat container capacity. The shapes of various packages are also kept as unconventional as possible so that less materials are used and less waste is produced.
4.2 Enhancing recycling of packaging waste If packaging waste is disposed of in the environment, it is likely to cause environmental pollution. However, many packaging wastes are not waste, most of which can be recycled and used, such as packaging paper, cartons, glass bottles, plastic bottles, wooden boxes, etc., some of which can be repackaged, and some can be used as packaging materials. Recycling is an effective way to reduce packaging pollution and protect the environment. It can also save a lot of packaging resources and energy.
4.3 Development of New Packaging Materials Packaging materials cannot be packaged, and green packaging calls for easily degradable packaging materials. The “white pollution†that people hate at the moment is because the plastics used to make these packaging materials are difficult to degrade and become public hazards. With the unremitting efforts of scientists, new types of packaging materials such as vegetable packaging materials and new plastics that can be naturally degraded are available.
For example, Japan has developed an edible multi-functional ecological packaging material, which is made of natural polysaccharides extracted from seagrass and woods as the main raw material. It is dissolved when heated and is suitable for packaging convenience foods. The United States has developed soybean protein. Edible packaging film, which can guarantee moisture, but also can prevent oxygen from entering, but also guarantee the quality of fat-containing foods. China has also developed new packaging materials such as paper-based plastics and easily degradable plastics.
