Environmental protection and green packaging

With the rapid economic development, China's packaging industry has also been relatively rapid development, resulting in increased packaging waste. It is estimated that China produces about 15 million tons of packaging waste each year, especially "white pollution", which is mainly caused by plastic packaging products. China's current plastic packaging materials have been discarded by nearly 1 million tons per year. The most prominent are plastic food lunch boxes, cutlery, cup plates, electrical foam packings, beverage bottles, yogurt cups, and various candies and small food plastic outer packagings and various plastics. Packaging bags, etc., These plastic products will not be rotted or degraded after being discarded for more than 100 years. The amount of garbage formed is difficult to manage, and the environmental pollution caused by a large amount of packaging waste has attracted the attention of all countries in the world. How to consider raw materials from the packaging design, the selection of the packaging of the goods, the environmental impact of the packaging, and the use and handling of the packaging. In order to meet the world market's new competition caused by the new standards and new regulations put forward by countries on packaging materials and packaging waste, it is necessary to vigorously develop green packaging that reduces the use of materials, has the least amount of waste, is easy to recycle, or can be self-degraded. Trends, the inevitable result of resolving the relationship between environmental protection and economic development. The packaging industry shoulders the heavy responsibility of solving packaging waste disposal and reducing environmental pollution. Environmental protection is a very complicated issue. It puts forward the following requirements for packaging: 1. Improve the function of packaging materials, save the amount of packaging materials, reduce the amount of packaging waste, and reduce the amount of packaging waste; 2. The used packaging containers Reducing the volume through folding and pressurizing reduces the cost of recycling and transportation; 3. If the packaging material is composed of multiple materials, it can be separated into single-component materials after use so as to be recycled. 5. If the packaging waste is treated by combustion, its material should have low thermal effect and no toxic gas will be produced. 6. Packaging waste can be decomposed under natural environmental conditions to reduce the burden of environmental pollution. Therefore, environmental protection has set a new goal for the packaging industry, requiring packaging products not only in quantity and quality, but also in packaging and decoration, structural design to reach the international advanced level. The general trend of the development of the world packaging industry is that in the next 10 to 15 years, international packaging standards and regulations will be harmonized with environmental protection. Therefore, the overall goal of the development of China's packaging industry should be: 1. Development of "moderate" packaging to reduce packaging waste The amount of production, to avoid excessively luxurious packaging and over 20% of the product volume of fat-enhanced large packaging, reduce the amount of packaging materials used, improve the strength and thickness of packaging paper, to achieve the purpose of saving packaging, reduce the amount of packaging; The starting point of industrial development will be to save energy, save resources, and protect the environment, so that the packaging will develop economically, automatically, efficiently, and in more detail. 3. It is necessary to use low-cost and high-efficiency products to obtain the best packaging and recycling of waste packaging; 4. The use of high-performance, functional packaging materials and products to replace the traditional packaging; 5. Further improve the recycling rate of packaging, recycling, development of packaging, such as waste paper, aluminum cans, tin cans and other packaging waste, recycling after recycling; 6. Choose harmless packaging materials and vigorously develop green packaging. Therefore, environmental protection has brought new challenges to the research and development of packaging materials, and has set a clear direction for the research and development of packaging machinery. The green wave of green packaging has flourished all over the world. Green has become a color representing the environment, representing the forest, and a symbol of life. It means that it accords with environmental protection standards and has no pollution. Green packaging is a kind of green industry and it is the general trend of the world packaging industry to adapt to the development of the world environmental protection trend. The so-called green packaging also known as environmentally friendly packaging, usually refers to the packaging from the design, production and production to the post-consumer waste disposal are fully in line with environmental standards, that is, it must have three conditions: 1. When packaging, meet the conditions of the packaging function The next, the application of the most provincial. Saving resources and energy, packaging waste is the least. 2. The waste packaging materials can be degraded on their own, and they can be quickly decomposed and destroyed after burying, self-extinguishing, no pollution to the environment, no toxic gas and secondary pollution when incinerated, and easy to generate cycles. 3. Packaging waste is easy to recycle, can be recycled and recycled. Therefore, green packaging is made with a minimal amount of packaging materials and developed with perfect packaging features, especially with environmentally friendly packaging. The meaning of green packaging materials Because the resources consumed by the packaging, energy, and the pollution of the used wastes to the environment are determined by the packaging, the packaging materials play a decisive role. The consumption of resources and energy, the design of container structures, and the choice of production methods are all related to and controlled by the packaging materials. Therefore, packaging materials become the key to determine whether the packaging is “green”. We call this material “green”. Packaging Materials". A green packaging material is a material that can be used as a waste but is not polluted by the environment. The process is green packaging material-finished product-use-waste-recycling-finished product, or material that is directly and naturally degraded without using waste. Therefore, the green packaging mainly involves the design, development, development and application of packaging materials and reuse of recycling processes, but the goal of green packaging cannot be achieved only by the efforts of packaging material workers. Green packaging is a systematic project. The development of the packaging industry should first develop the packaging machinery industry. To achieve the goal of green packaging, it is first necessary to develop all types of machinery and equipment suitable for green packaging. Green packaging machinery is the "hardware" equipment for green packaging. With the emergence of better-performing packaging materials, packaging machinery must undergo technological innovation to adapt to the processing and forming of new materials. Packaging, printing, and interior design must be completed on thinner materials. Only packaging design, packaging materials, packaging testing, Only by combining various aspects such as packaging machinery, packaging and printing, and packaging standardization and regulations, can this system project be completed, and the objectives of green packaging to reduce materials and energy, protect the ecological environment, and improve human living conditions can be achieved. The current situation of packaging machinery industry Although the development of China's packaging machinery industry began in the 50s and 60s, as a new industry, it began in the late 1970s, developed in the 1980s, and showed rapid growth in the 1990s, with an average annual growth rate of 20 to 30. %. At present, there are about 1,300 packaging machinery manufacturers in China, 75 research institutes, and another 21 institutions of higher learning engaged in teaching and scientific research of packaging machinery, thus forming a certain level of packaging machinery development and production capabilities. China currently has more than 2,700 kinds of packaging machinery products in 40 categories, among which 5 to 20% of the varieties have reached the level of the late 1970s and early 1980s, and a few have reached the level of the foreign 80s, among which more than 20 products are of similar quality to imported products. The low level of products can not meet the needs of market development. Mainly due to monotonous product modeling, low production efficiency, single machine, supporting units, production lines, labor-intensive products, high-tech products, and meet the green packaging requirements of the product variety, quantity, technology level is low, For example, the pulp molding machine that replaces plastic products is still at the primary stage in China. The variety is single and rough. It started with the introduction of foreign technology to produce simple egg tray equipment in the 1980s, and now produces nearly 100 pulp molding equipment manufacturers. There has been a great deal of development, and the level of equipment has also been continuously improved. The paper and lunch box equipment has gone from manual to an automatic production line with a daily output of 100,000 pieces. There are more than 20 two-piece beverage cans production lines currently under construction in our country, all of which are aluminum products. The steel two-piece cans have advantages over aluminum cans in terms of waste sorting and processing costs. Germany and other European countries have developed rapidly. They have evenly divided themselves from aluminum cans. However, there is currently no steel can production line in China. The steel tank manufacturing equipment developed and manufactured in China is still blank. Adapting to the development direction of green packaging to develop green packaging is of great significance to China's adaptation to the world market of environmental protection, as well as the full use of resources and the establishment of a resource regeneration system. In the future, the development of the packaging machinery industry should closely integrate the development and production of packaging materials with environmental protection, develop appropriate packaging, and consider the ease of recycling and recycling of packaging materials, and follow the principle of minimizing packaging waste and forming a recycling of resources. The development of paper pulp molding products has many varieties of packaging paper, easy recycling, and can undertake a variety of packaging tasks. The raw materials for the production of pulp molded products can be mainly used as a year's herb fiber pulp, such as reeds, straw, bagasse, etc. Its wide source and low construction cost are inexhaustible and there is no waste of resources. From the production, consumption, and disposal of wastes, they are all free from pollution and protect the environment. Product waste is easy to recycle and reuse. Even if it is not recycled, stored and naturally degradable, it is conducive to ecological balance. Therefore, it is necessary to develop and develop mechanical equipment for pulp molding products that are conducive to environmental protection. Paper products and silk products have the tendency of replacing plastic packaging in food packaging in the future. However, China's current paper product packaging equipment has few varieties and its technical level is relatively backward, and it cannot adapt to the environmental protection requirements of green packaging. In the future, we shall focus on the development of medium and heavy-duty corrugated carton packaging and equipment, white cardboard box packaging and equipment, various moisture-proof papers and equipment that replace plastic films, and various fiber membranes and equipment that can replace plastic agricultural films, while striving to develop and adapt to various Different requirements for paper cupboard equipment and a variety of equipment suitable for industrial packaging A type corrugated cushion, honeycomb, cardboard, pulp cushion, corrugated and starch made of corrugated sandwich cushion and other equipment, instead of foam material Fast food box and cushions. Development of glass bottle packaging development Glass bottle packaging, especially the development of high-strength thin glass bottles and equipment, and strive to improve the technical level of glass bottle packaging equipment. Because glass bottles and cans have the advantages of ensuring the purity of food beverages and hygiene, transparency, aesthetics, good chemical stability, airtightness, easy sealing, flexible modeling, abundant raw materials, and low price, the use of environmental protection is less contaminated and easy to use. It can be recycled and used many times. It is the main container used extensively in the food, medicine, and chemical industries in the future, especially beverages and various oral liquids. Therefore, we should develop and develop container equipment and filling equipment for various beverages and oral liquids to improve the quality and efficiency of mechanical products and meet the different needs of the market. Development of Bamboo Packaging China is a country lacking timber in the world. However, the total area of ​​bamboo forests and bamboo resources in China ranks first and second in the world. Therefore, we must fully develop the use of bamboo resources and develop all kinds of non-polluting and easily recycled bamboo glue. Board packaging equipment is of great significance to the development of packaging materials and equipment. Two-piece and three-piece cans are easy to recycle because of two-piece and three-piece aluminum cans, steel two-piece cans (the trend of replacing aluminum cans), three tin cans, and steel packaging boxes, and are profitable and can be used repeatedly. Therefore, it is a promising material. China should increase the amount of packaging according to the increase in metal products, and at the same time develop its equipment to meet the needs of the market. The research and development of plastics recycling and recycling processes have been devoted to the research and development of plastics recycling and reproduction processes. Plastics packaging plays a major role in the prosperity and development of the world packaging industry. Due to the indecomposable nature of plastics, various types of plastic packaging have caused more and more pollution to the environment, but many other properties of plastic packaging cannot be replaced. At present, the United States, Japan, Germany and other countries have developed biodegradable plastics. The development of degradable plastics needs to be strengthened so that its technology and research level will continue to increase. Packaging machinery is the basis and equipment of the modern packaging industry. Green packaging materials are the foundation of green packaging. Their development, research, and development will play a decisive role in the development of green packaging for the development of the entire packaging industry. In the future, the packaging industry should take a road that is compatible with the environment, avoid the old road of “pollution after pollution,” give priority to the development of the packaging machinery industry, and extensively and accelerate the use of modern methods, from packaging materials and auxiliary materials to packaging technologies and equipment, and packaging waste. In terms of material management, the "Green Packaging Project" is fully implemented.
