Green packaging: the ultimate choice of mankind

generally speaking, 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 everything is appropriate, appropriate packaging avoids the damage and deterioration of commodities, beautifies and protects commodities, and saves resources; The production of packaging materials will reduce resources, packaging waste will increase environmental pollution, and excessive packaging will waste resources and tensile strength and damage the environment. The foothold of the development of packaging industry should be the effective utilization of resources and the improvement and protection of the ecological environment

however, at present, the 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 harmful packaging pollutants, and has formed the coexistence of point source and non-point source pollution, the superposition of domestic packaging product pollution and waste discharged from industrial production packaging products, as well as the composite situation of various old and new non degradable packaging pollutants and secondary pollution The interaction pattern of water and soil pollution poses an increasingly serious threat to the ecosystem, food safety and human health. Therefore, green packaging will be our eternal pursuit and our ultimate choice

green packaging originated from our common future issued by the United Nations Commission on environment and development in 1987, and the Rio Declaration on environment and development and Agenda 21 were adopted by the United Nations Conference on environment and development in june1992. It is a green concept with the protection of the ecological environment as the core, that is, it is harmless to the ecological environment and human health, can be recycled and recycled, and can promote the sustainable development of the national economy. In other words, the whole process of raw material selection, product manufacturing, use, recycling and waste of packaging products should meet the requirements of ecological environment protection. It includes the eco-environmental protection requirements of saving resources, energy, reducing, avoiding waste generation, easy recycling, recycling, incineration or degradation, etc. Of course, the content of green packaging will have new connotation with the progress of science and technology

at present, we divide green packaging into Grade A and Grade AA. A-level green packaging refers to appropriate packaging that can recycle, recycle or degrade wastes and contains toxic substances within the specified limit. AA grade green packaging refers to appropriate packaging that wastes can be recycled, recycled or degraded, and do not cause public hazards to human body and the environment in the whole life cycle of the product, with toxic substances within the specified limit. The above classification mainly considers that the problem of waste after packaging should be solved first. This is the pollution in the process of environmental protection around the world. It is a problem that needs to be solved in the past, now and in the future

at present, there are many typical green packaging materials in the world, such as degradable plastic, edible packaging film, paper packaging that can be naturally decomposed, non-toxic, pollution-free and easy to recycle bamboo packaging, glass packaging that does not contain metals, ceramics and other substances and is easy to recycle, etc

"degradable new plastic" has the excellent quality of self decomposition and disappearance after being discarded, and does not pollute the environment. Nowadays, Germany has invented a kind of packaging cup made of starch, which can hold dairy products and is easy to decompose after being discarded; And the United States developed a kind of plastic bag with starch and synthetic fiber as raw materials, which can be decomposed into water and carbon dioxide in nature

"edible packaging film" for example, the glutinous rice paper used in candy packaging and the corn baking packaging cup used for ice cream packaging are typical edible packaging. The more mature synthetic edible packaging film is the industrialized pullulan resin in the 1970s. It is tasteless, odorless, amorphous white powder in August 2016. It is a non-ionic, non reducing stable polysaccharide. Because it is a polydextrose composed of a-glucoside, it is easy to dissolve in water and can be used as viscous, neutral and non-ionic non gelatinized aqueous solution. Edible packaging film is transparent, colorless, odorless, non-toxic, with toughness, high oil resistance, edible, and can be used as food packaging

"paper packaging" can be recycled after use. A small amount of waste can be naturally decomposed in the natural environment and has no adverse impact on the natural environment. Therefore, it is universally recognized that paper, cardboard and paper products are green products, which meet the requirements of environmental protection and can play a positive role in replacing the white pollution caused by plastics

"bamboo packaging" refers to bamboo plywood boxes, silk bound bamboo crates, etc. It is non-toxic, pollution-free and easy to recycle. For China's total bamboo forest area and bamboo resource volume rank first and second in the world respectively, developing bamboo packaging with strong traditional culture in China is very popular with the public

"glass packaging" is a kind of packaging material that can be almost completely recycled, and glass packaging has the advantages of strong visibility and easy recycling. It has become the main container for traditional packaging of beverages and other products, and has been recognized as a pollution-free packaging material in the world

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, paints, etc. used on the packaging containers or labels shall use the raw materials that do not contain heavy metals as the adhesive of the bonding materials. In addition to not containing toxic or toxic components, they shall also be easy to decompose during separation. It is required to use recycled materials as much as possible, and plant packaging materials shall be actively developed

as a youth in the 21st century, we should set up a lofty ideal and make greater efforts for the green packaging industry. Push the human society into the era of green packaging in an all-round way, completely change the current situation of packaging pollution in the future, and enable people to have a green, healthy and vibrant living environment
