Paper packaging and environmental protection

"The last drop of water that humans see will be their own tears. Please take care of every drop of water." In the current international situation of saving energy and preventing environmental pollution, pollution-free and pollution-free “green packaging” is quietly rising in the world. I. The meaning of green packaging and the so-called green packaging of the LCA technology evaluation method have not yet seen a complete definition. I believe that there are generally four aspects, namely: the least material, the least waste, and saving resources and energy; easy recycling and recycling; waste combustion produces new energy without secondary pollution; packaging materials and Decompose on your own without polluting the environment. The packaging and the environment complement each other. On the one hand, the packaging needs to consume energy and resources in its production process. The generation of industrial waste and packaging waste will pollute the environment. It also needs to see that the packaging protects the goods and reduces the damage of the goods in circulation. It is conducive to reducing environmental pollution. At present, to resolve the relationship between packaging and the environment, it is not just to consider how to deal with packaging waste. Instead, it considers that the packaging products needed by people in all activities are the consumption of natural resources and energy, the generation of waste and the impact on the earth. The environment as a price. Therefore, the goal of packaging is to preserve the maximum natural resources, to form the minimum amount of waste and minimal environmental pollution. In the 1970s, environmental experts proposed LCA (Liee C yc le A sse ssm en t), the "ecological cycle assessment method." At present, LCA technology is attracting attention internationally. In Japan, the United States, Germany and other countries have used this analysis to evaluate packaging materials. The selection of packaging materials from raw materials, material processing and manufacturing, and disposal or recycling of waste materials has a direct relationship with the environment. With LCA technology, these impacts can be quantified and corresponding improvement measures can be formulated. Second, paper packaging is the most promising green packaging modern packaging of the four pillars - paper, plastic, metal, glass. Among these four kinds of packaging materials, paper products have the fastest growth, paper and plastic are the cheapest, raw materials are widely available, and are not as fragile as glass, and they are not as heavy as iron and are easy to carry. Therefore, paper and plastic packaging are widely used in daily life. The International Health Organization and domestic environmental protection experts believe that domestic and foreign markets will gradually ban the use of plastic food bags, and regulations must be packaged in environmentally friendly paper bags. In the future, shopping should use non-toxic and harmless “full paper eco-friendly bags”. Paper products are prone to decay and can either recycle recycled paper or use as fertilizer for plants, reduce air pollution, and purify the environment. At present, China's food, medicine, glassware, instrumentation, electrical and mechanical light industry products are mostly plastic products. In order to seek new alternative materials, the Ministry of Science, Technology, Industry, Technology, and Technology Development Department has developed a waste paper recycling plastic packaging. Material production technology and complete production line. The waste paper imitation plastic packaging materials produced by the technology have good air permeability, flexibility, toughness and strength, and the products are non-toxic, non-polluting, rich in raw materials, and low in cost, and can be widely used for inner packaging of various products. Therefore, paper packaging and plastic, metal, glass and other three major packaging compared, and the use of LCA technology for quantitative evaluation, paper packaging will become one of the most promising green packaging materials. III. Recycling and prevention of paper packaging waste and environmental pollution Cartons, paper bags, paper drums and pulp molded products have become an important part of the modern packaging industry. Paper packaging containers are light in weight, easy to process, low in cost, and easy to recycle. Processing and other features are widely used in transport packaging and system packaging. At present, the output of paper and paperboard is increasing year by year. Packaging paper and paperboard account for more than 50% of the total output of paper and paperboard. The per capita consumption of paper has become an important indicator of the economic development level and social civilization of a country. Every year, such a large amount of paper and board are used for packaging, and a large amount of paper packaging waste will also be generated. How to use this waste has attracted more and more attention, both for the environment and for the use of resources. The recycling of paper packaging waste has the following aspects: (1) The recycling of paper packaging waste can reduce the consumption of natural fiber raw material resources and solve the shortage of packaging resources. At the same time, it can save a lot of packaging raw materials and energy. (2) The recycling of paper packaging wastes will greatly reduce production costs and achieve greater social and economic benefits.
