Green Packing: Human Choice

In general, there are three types of packaging: moderate packaging, excessive packaging, and lack of packaging. The development of the packaging industry is in contradiction with the conservation of resources. In fact, as long as it is moderate, moderate packaging will prevent deterioration of the product, beautify and protect the goods, and it will save resources; the production of packaging materials will reduce resources, and packaging waste will increase environmental pollution. Excessive packaging will waste resources and damage the environment. The foothold for the development of the packaging industry should be the effective use of resources and the improvement and protection of the ecological environment.

However, at present, environmental pollution caused by packaging in China has spread from land to offshore waters, from surface water to groundwater, from general packaging pollutants to toxic and hazardous packaging pollutants, and point sources have been formed to coexist with non-point source pollution. The pollution of packaging products and the industrial production of packaging products and the discharge of waste, and a variety of new and old non-degradable packaging pollution products and secondary pollution mutual recombination situation, atmosphere, water, soil pollution interaction pattern, the ecosystem, food safety, human body Health poses a growing threat. Therefore, the green packaging will be our eternal pursuit, and it is also our ultimate choice for humanity.

Green Packaging originated from the "Common Future of Ours" issued by the United Nations Environment and Development Committee in 1987. By June 1992, the United Nations Conference on Environment and Development adopted the Rio Declaration on Environment and Development and Agenda 21. It is based on the concept of protection of the ecological environment as the core of the green concept, that is not harmful to the ecological environment and human health, can be recycled and reused, can promote the sustainable development of the national economy packaging. In other words, the entire process of packaging products from raw material selection, product manufacturing, use, recycling and disposal should meet the requirements of ecological and environmental protection. It includes such contents as conservation of resources, energy, reduction, avoidance of waste generation, easy recycling, recycling, incineration or degradation, and other ecological and environmental protection requirements. Of course, with the progress of science and technology, the development of packaging will also have new connotations.

At present, we divide the green packaging into A grade and AA grade. Grade A green packaging refers to the appropriate packaging of wastes that can be recycled, reused or degraded, and contain toxic substances within the specified limits. Grade AA green packaging refers to waste that can be reused, reused or degraded, and does not cause harm to the human body and the environment throughout the product life cycle. Moderate packaging of toxic substances is within the specified limits. The above classification is mainly to consider the issue of waste after packaging is first used. This is pollution in the process of protecting the environment around the world. This is a problem that needs to be solved in the past, present, and future.

As far as the world is concerned, there are many typical green packaging materials, such as biodegradable plastics, edible packaging films, paper packages that can be naturally decomposed, bamboo packaging that is non-toxic, non-polluting, and easy to recycle, and do not contain metals. Other materials such as ceramics and glass packaging that are easy to recycle.

"Degradable new plastics" have excellent qualities that self-decompose after being discarded and do not pollute the environment. Today, Germany has invented a packaging cup made of starch that encounters liquid insolubilization. It can contain dairy products and is easily decomposed after being discarded. In the United States, a plastic bag made of starch and synthetic fibers is developed. It can be broken down into water and carbon dioxide in nature.

"Edible Packaging Film" As is well known, glutinous rice paper used for candy packaging and corn baking packaging cups for packaging ice cream are typical edible packaging. Among the more mature synthetic packaging films is the pullulan resin that has been industrialized since the 1970s. It is an odorless, odorless, amorphous, amorphous white powder that is non-ionic, non-reducing, and stable. Polysaccharides. Since it is a polyglucose composed of a-glucoside, it is easily dissolved in water and can be used as a viscous, neutral, nonionic, non-gelatinized aqueous solution. Edible packaging film It is transparent, colorless, odorless, non-toxic, has toughness, high oil resistance, can eat, and can be used for food packaging.

After being used, “paper packaging” can be recycled again. A small amount of waste can be naturally decomposed in the natural environment and has no adverse impact on the natural environment. Therefore, the world recognized that paper, paperboard and paper products are green products and meet the requirements of environmental protection. Governance The white pollution caused by plastic can play a positive role.

"Bamboo packaging" refers to: bamboo plastic box, silk box tied bamboo box. It is non-toxic, non-polluting, and easy to recycle. As for the total area of ​​bamboo forests in China and the reserves of bamboo resources in the world, ranking first and second in the world, the development of China's bamboo packaging with rich traditional culture is very popular.

“Glass Packaging” is a packaging material that can be recycled almost completely. Glass packaging has the advantages of high visibility and easy recycling. It has become the main container for traditional packaging of beverages and other products. It has been recognized by the world as pollution-free. Packaging Materials.

At present, China is actively developing various green packaging materials and has done a lot of work, such as avoiding the use of toxic materials. The pigments, dyes, and paints used on packaging containers or labels should be made of materials that do not contain heavy metals. As adhesives for bonding materials, they should not be toxic or toxic, but should also be easily decomposed when they are separated. It is possible to use recycled materials and actively develop plant packaging materials.

Especially as young people in the 21st century, we must also establish a lofty ideal to make greater efforts for the green packaging industry. The human society will be fully promoted in the era of green packaging, completely changing the pollution status of packaging, so that people can have a green, healthy and full of life.
