The most popular green packaging is the sustainabl

  • Detail

Green packaging is the road of sustainable development of packaging industry. Green packaging focuses on the ecological balance between man and nature, and tries to reduce the damage to the living environment to construct the design strategy, so as to promote the development of economy, culture and society with green packaging; Green packaging fully reflects the thought and strategy of mutual coordination and sustainable development between environmental protection and economic development. Protecting the environment and developing green packaging has become an inevitable choice for all countries in the world to develop packaging, and green packaging will become an inevitable trend for the development of packaging industry. 1、 The development status of green packaging in China

(1) the industry is developing rapidly. Due to the pressure of using green packaging for export commodities, the rise of domestic environmental protection undertakings and the support of the government, China's green packaging industry has developed rapidly. More and more environmentally friendly packaging materials are used, the market share is gradually rising, and the technical content is becoming higher and higher. Some products have reached the international advanced level and have a good market in the international market. The packaging machinery that produces green packaging products also has the momentum of booming production and marketing. However, at the same time, improper packaging such as excessive packaging and false packaging has gradually intensified, which has attracted the attention of the society, and some measures have been taken to make the packaging gradually embark on the road of standardization. In terms of packaging waste disposal, a few professional packaging waste recycling organizations have been established, and there is a trend of industrialization

(2) the comprehensive utilization rate of green packaging products is low. In China, a large number of packaging containers and contents are discarded due to poor management of green packaging every year, and the direct economic loss is more than 15billion yuan, 70% of which is caused by transportation packaging. For example, the breaking rate of cement is 15% - 20%, and the annual loss is about 3million tons; The average breakage rate of glass is 20%, and the annual loss is 4. 5% 500million yuan. In addition, according to the statistics of the foreign trade department, due to the backward level of green packaging technology for export commodities, the foreign exchange income of the country will be reduced by at least 10% every year

(3) unbalanced regional development. The implementation of green packaging in different enterprises is not synchronized. The earliest enterprises to implement green packaging are all export-oriented enterprises. Affected by the international market, such enterprises have an early understanding of green packaging and quickly adjusted their packaging strategies. However, enterprises mainly in the domestic market have been slow to respond to green packaging, and only in recent years have they started to set foot in green packaging. Secondly, the development among regions is uneven. The green packaging in economically developed regions is developing rapidly, while the green packaging in economically backward central and western regions has not been paid enough attention and publicity, and the development is slow. In terms of the treatment of packaging waste, the policies and laws with definite mosquito repellent effect in different regions are inconsistent, resulting in the transfer of packaging pollution to economically underdeveloped areas

(4) insufficient investment in capital, technology and talents. Due to the use of advanced technology and the limitation of the production scale of enterprises, the cost of green packaging products is often higher than that of traditional packaging products, so they do not have the price advantage when competing with traditional packaging products. This has directly led to the disadvantages of green packaging products in the market competition, and seriously affected the confidence of enterprises in the development of green packaging. Green packaging is supported by high technology. Due to the lack of investment and Research on new green packaging technologies, although some products have the international leading level, the overall technical level is still backward. In addition, there is a great shortage of talents in green packaging in China, especially the lack of management talents, which seriously restricts the development of green packaging

II. Measures for the development of green packaging in China

(I) legalization of packaging management

in order to protect their own ecological environment from pollution, the world's economically developed countries have formulated environmental protection laws and regulations related to packaging, managed the production, circulation and use of packaging according to law, and reduced the pollution of waste to the environment. Generally, the legislation of various countries focuses on two aspects: first, the production, use and recycling process of various packaging containers are targeted, and there are laws to follow. For example, according to the relevant German laws and regulations, the manufacturers and sellers of packaging products should be responsible for the whole life cycle of the products. The manufacturers and sellers of products and packaging developed a 40 inch graphene touch screen panel in 2011 have the obligation to recycle and dispose of the waste generated by their products and bear the necessary expenses; The recycling ratio of main products and transport packaging materials is specified (milk 17%, beverage 72%, paper and plastic 64%, transport packaging 100%). Second, the use of packaging materials harmful to packaging products, the environment or consumers is prohibited. For example, in order to protect the ozone layer, the European community, the United States, Japan, South Korea, Australia, Singapore and other countries have successively prohibited the use of CFCs containing foamed plastics. However, as far as China is concerned, there is no special packaging law and regulation, which makes many problems related to packaging and environmental protection impossible to follow. In view of the practice of industrial countries in the world, combined with the actual situation of our country, packaging legislation is imperative

(II) establish an effective packaging waste recycling system

for enterprises, the recovery and recycling of packaging waste can not only create considerable economic benefits, but also produce good environmental benefits. Take the recycling of cans as an example. If one ton of cans is refined again, 4 tons of bauxite can be mined less, 017 tons of ingredients can be saved, and 35 kg of aluminum fluoride polluting the air can be discharged less. Packaging industry is a cross sectoral and cross regional industry. The establishment of China's packaging waste recycling system should be based on laws and regulations. The packaging industry, the national environmental protection department and the national environmental sanitation department should coordinate with each other to standardize the behavior of packaging producers, commodity producers, sellers and consumers, and clarify the status, obligations and core components of packaging producers, commodity producers, sellers and consumers in the system: green packaging and the classification and recycling of packaging waste Manage the disposal of packaging waste

(III) promoting cleaner production

for the packaging industry, the potential of cleaner production is great. We can consider recycling, harmlessness and waste reduction in the whole life cycle of product packaging; Improve packaging design; Promoting green technology; The idea of cleaner production will run through the whole process of packaging production and use to minimize the harm of packaging waste to the environment. By carrying out cleaner production and adopting green technology, the enterprise can achieve sound development

(IV) implement packaging reduction

(1) prohibit excessive packaging, advocate appropriate packaging and promote simple packaging

(2) through the effective use of packaging size, promote the centralized packaging of products and the centralized service of less packaging and more, promote the formulation and standardization of the transport packaging benchmark size for the transportation of products with special specifications, and try to improve the capacity of packaged goods

(4) by improving the structure, the product volume is reduced and the amount of packaging materials is reduced

(5) improve the strength by selecting new materials or modifying materials to make the packaging lightweight and thin

(V) development of green packaging materials. Therefore, in the selection of packaging materials:

(1) avoid using toxic materials. The pigments, dyes, paints, etc. used on the packaging containers or labels shall be made of raw materials that do not contain heavy metals. The adhesives used as bonding materials shall not contain toxic or toxic components, but also be easy to decompose during separation

(2) use recycled materials as much as possible. At present, most of the recyclable recycled materials used in the world are recycled paper, such as recycled cartons, molded pulp, peak pulp paperboard and paper tubes made from recycled waste paper

(3) actively develop plant fiber packaging materials. Plant fiber can basically continue to reproduce, and the extensive use of plant fiber will not cause harm to the environment, ecological balance and resource maintenance, so it is favored by the international packaging market. For example, corn stalk is used as raw material to produce biodegradable plastic film, and starch and plant fiber are used as raw materials to produce expanded "foam" materials

(4) select single packaging material. In this way, the material can be disassembled without using the special worker Jinan testing machine factory to adjust the error tool, which can also save the recovery and separation time and avoid the difficulties of recovery and separation caused by the use of bonding method

(VI) establish professional organizations

many countries have established various professional organizations to evaluate packaging materials, implement the green dot plan, and strengthen the implementation and management of packaging recycling. For example, France has a National Packaging Research Institute composed of twoorthree experts; Germany has set up a special laboratory to assess the damage of various existing packaging materials to the environment according to relevant ISO standards, and has established a dual recovery system (DSD). This system provides two optional recycling channels: one is that the suppliers recycle the packaging materials themselves; the other is that a private and non-profit organization has been established to organize the recycling of packaging materials. Suppliers can apply for membership and pay a certain management fee to become members. The packaging materials of member enterprises are printed with recyclable marks. After adopting this measure in 1995, the recovery rate reached more than 80% and the consumption of packaging materials was greatly reduced

in a word, with the development of economic globalization, China's packaging industry is facing great challenges and opportunities. Implementing the green packaging development strategy, vigorously strengthening the establishment and improvement of the policy and theoretical system of green packaging, and realizing the overall optimization of the packaging system are conducive to environmental protection, economic growth and the sustainable development of China's packaging industry
