Green Design and Implementation of Domestic Packaging Industry (Part 2)

Third, green packaging materials

The basic requirements for green packaging materials are easy recycling and no pollution. Green packaging materials mainly include the following types:

(1) Plastic packaging. At present, the internationally popular "degradable new plastics" have excellent qualities that are self-decomposing and disappear after being discarded and do not pollute the environment.

(2) Paper packaging. Paper packaging variety, easy to recycle. At present, many companies have considered the use of medium-sized, heavy-duty pressure cardboard boxes or white cardboard boxes to package, and use a variety of moisture-proof fresh paper instead of plastic film for packaging. Nowadays, the recycling technology of waste paper is also relatively mature. Waste paper and waste paper boxes can also be used to remanufacture different secondary products of different qualities according to their colors and composition. In Japan, recycled paper shopping bags have become fashionable and used by major department stores.

(3) Glass packaging. High-strength, thin-walled, lightweight glass is increasingly being used. If you do not contain metals, ceramics, and other substances, almost all of the glass can be recycled.

(4) Bamboo packaging. Bamboo packaging has the characteristics of being non-toxic, non-polluting, and easy to recycle. It also meets the principles of “resources, reduction, and harmlessness” advocated by the state. Bamboo packaging refers to: Bamboo plastic box, silk bundle box and so on. China is a country lacking timber in the world, but China's total bamboo area and bamboo resources rank first and second in the world respectively. China's bamboo packaging with rich traditional culture is favored by countries in Europe, America and Japan.

(5) Metal packaging. It is easy to recycle, can be used many times, recycling can be profitable and so on. Metal packaging usually refers to two-piece or three-piece aluminum cans and three pieces of tinplate cans that use resistance welding and steel packing boxes.

Fourth, the implementation of green packaging

The development of green packaging is not only a serious challenge to China's packaging industry, but also an opportunity for development. Although China's packaging industry has achieved rapid development in the past 18 years, it is still a late start compared with the developed countries in the world, the total output value and per capita packaging consumption are small, and most of the production technology has not yet been finalized. Therefore, the burden of technological transformation with green packaging is small, and the speed is fast. In addition, the packaging industry in China is currently facing problems such as shortage of raw materials. It is also possible to seek solutions from the recycling of packaging materials. Therefore, both in terms of necessity and possibility, we should all make an early determination to actively embrace the technological revolution of the packaging industry and strive to do a good job of the "Green Packaging System Project." In the new round of competition in the international packaging market, we must catch up with the world. The advanced level has become a new force for the world's green packaging.

Formulate national green packaging development plan

The development of 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. However, the development of green packaging will have many difficulties in changing traditional habits and increasing costs in the transformation of existing packaging materials, recycling of recycled packaging waste, etc. Therefore, national competent authorities are required to perform administrative intervention and macro-coordination functions.

Strengthen environmental protection education for packaging, promote green products

Strengthen the publicity and education on environmental protection of packaging, and establish a sense of active participation of packaging workers and consumers. One of the primary tasks for the development of packaging environmental protection campaigns is to adopt various forms of publicity and education activities to cultivate and foster awareness of environmental protection and participation of all citizens. Implement product green signs and implement policy tilt. Green signs, also known as environmental signs and ecological signs, refer to the issuance of certificates to relevant manufacturers by government agencies or public bodies in accordance with certain environmental standards to prove that their production, use and disposal processes are all in compliance with environmental protection requirements and are not harmful to the environment. The harm is minimal, and it is conducive to the regeneration and recycling of resources. If a product has achieved the green mark, it means that it has obtained the “pass” to enter the green flag market. Otherwise, the competitiveness of the product will be seriously affected. The green sign has become an effective way for companies to increase economic efficiency, open up markets, and establish an image.

Implementing green signs on products can also increase public awareness of the environment, guide consumers to choose products that are less harmful to the environment, and also promote factories to produce products that are environmentally sound and harmless, and carry out production processes in accordance with environmental requirements. Control management. All products marked with a green mark are easily accepted by foreign investors in foreign trade and can be subject to preferential tariffs and prices. Contrary to products without green marks, some foreign companies may refuse to sell, and they cannot obtain preferential prices and customs duties. Therefore, the green sign is also conducive to promoting the export of goods.

Implement environmental legislation

Environmental protection legislation is to regulate the production, circulation, and use of packaging through legislation and promote the development of green packaging according to law. This is a common and effective measure adopted by various industrial countries in the world. In many countries, legislation dictates that producers must use green packaging, which is most evident in Europe.

The environmental protection regulations implemented by various countries can be divided into two types: One is the monotonous packaging legislation and regulations, such as the prohibition of the use of certain materials, etc. Many cities in China have promulgated the prohibition of the use of polystyrene foam materials in the past two years. Disposable tableware belongs to this category. The other is the comprehensive packaging legislation and regulations, such as the "Declaration of Packaging Waste Disposal" enacted by countries such as Germany and France. Its legislative basis is "polluter pays" and "promotes advances in packaging technology."

Packaging reduction

Reduction is also called resource-saving technology. Packaging reduction is the first principle proposed in Europe to solve packaging and environmental problems and reduce the "3R" principle of packaging waste (Reduce, Reuse, Recycle). Packaging reduction should begin with packaging design and packaging material selection.

Protecting the ecological environment and developing substitute wood packaging

In the world environmental protection movement, one of the most important and wide-ranging tasks is to save the forest. Forests are the main body of terrestrial ecosystems. They are the most important production resources and environmental resources that nature has given to human beings. It is known as “green gold” and provides people with a large amount of wood, various raw materials, food and feed. It is also a "general dispatch room" and plays an important role in purifying the air, conserving water, and regulating the climate. The earth loses green, and human survival has become a problem.

In recent years, China has made significant progress in the saving of wood. In terms of packaging, based on domestic resources, we have vigorously developed and adopted various wood materials. Such as paper for wood, soil (magnesite) for wood, bamboo (bamboo plywood) for wood, plastic substitute wood. Particular emphasis should be placed on the fact that the total area of ​​bamboo forests and the amount of bamboo resources in China are ranked first and second in the world. Therefore, bamboo resources are fully utilized, and various non-pollution and easy-to-recycle bamboo plastic packaging boxes and bundles of bamboo are developed. The box is of great significance to the development of wood packaging materials in China. In order to reduce environmental pollution, protect the human ecological environment, and protect valuable forest resources, we should vigorously develop substitute wood packaging. In particular, we should develop corrugated cartons, bamboo plastic packaging boxes, containers, and plastic turnover boxes that are less environmentally polluting. package.

Using multiple waste treatment technologies, focusing on the development of recycling

The main content of the meaning of green packaging is that the waste is easy to handle and use pollution-free materials. The latter is mainly referred to as degradable plastic in plastics. It is essentially a treatment method that uses biological or light to decompose the packaging waste until it disappears. Modern urban solid waste (MSW, packaging waste belongs to its category) The main methods of disposal are landfill, incineration, recycling, recycling, composting, and degradation.

The development of the packaging industry has made great contributions to economic construction. However, on the one hand, product packaging consumes a lot of resources. On the other hand, packaging residues are a huge source of pollution that cannot be ignored and cause serious human Environmental issues. According to the results of the national poll conducted by the American "Packaging" magazine, the vast majority of people believe that the environmental pollution caused by packaging is second only to water pollution, marine lake pollution and air pollution. According to rough estimates of experts, the amount of waste discarded each year by the world is close to 10 billion tons, and packaging waste accounts for about 1/3, which accounts for 1/2 of the volume. These packaging materials not only consume resources but also occupy The huge space will consume a lot of processing cost. At the same time, many of the materials of the packaging are non-degradable and will remain in the environment for a long time. These wastes seriously affect the ecological balance and cause great pollution to the environment.

In today's society, packaging and environmental protection are being placed in front of people as a social hot spot and have become a serious problem that countries urgently need to solve. Therefore, green packaging is the common need for human survival and development. The development of green packaging is an inevitable choice in the 21st century. In the face of the global green packaging revolution, in order to allow our products to enter the international market more and better and remain invincible, China's packaging industry only makes great efforts to catch up with the world trend in product packaging, and the use of green packaging has a future. The packaging industry should follow the principle of environmental protection, use new technologies, and vigorously promote and promote green packaging, increase reuse and recycling of waste packaging products, save resources and energy, and make economic development a sustainable development path. Today, as science and technology continue to advance, people’s awareness of environmental protection is constantly increasing, and vigorous development of green packaging will bring us a clean green world without pollution.
