Exploring Green Packaging and Its Problems (Chinese)

At present, most of the packaging materials used are paper products, plastics, metals, glass, wood, etc. Most of the packaging materials have the basic conditions for achieving green packaging. Even with the rapid growth in the number of applications, plastic packaging materials once considered by people as "white pollution", there are many favorable conditions for the "green" packaging.

The advantages of "green" plastic packaging materials are summarized as follows:

The first is that plastic packaging materials can obtain good health and safety. The basic raw materials used in plastic packaging materials are various polymer compounds. Usually, they all have good hygienic properties, as long as we pay attention to strictly controlling the monomer content, strictly controlling the selection and application of the additives, and the hygienic properties of the plastic packaging materials can be fully guaranteed. The second is the large variety of plastic packaging materials, most of which can achieve clean production and avoid environmental pollution. Third, plastic packaging materials, which are basically thermoplastic plastics, can be heated and melted many times, and have properties that can be recycled and recycled. Fourth, most of them are flammable. Waste can also be disposed of by incineration and heat energy can be recovered. Fifth, the development and application of biodegradable plastics in recent years has solved the problem of environmental pollution caused by waste plastic packaging materials and created favorable conditions.

In addition, the plastic packaging industry has accumulated valuable experience in improving the environmental protection adaptability of plastic packaging materials. For example, we summarized the principle of improving the adaptability of plastic packaging waste to environmental protection—the principle of #%!(that is, reduction, reuse, recycling, and development of biodegradable plastics). Practice has proved that these measures can effectively reduce the environmental pollution caused by the waste plastic packaging materials entering the natural environment.

Therefore, we should have full confidence in the green packaging work.

Fourth, the beneficial revelation of China's prevention and control of "white pollution"

The development of green packaging must attach great importance to environmental protection.

Since the end of the last century, China has gradually entered the period of market economy. After vigorously developing commodity production, the production and application of packaging have also achieved tremendous development. However, for a long period of time, the emphasis on environmental protection has been insufficient. The negative impact of the production and application of packaging on the environment has become increasingly serious. The serious pollution to the environment caused by the waste of plastic packaging material and the formation of the so-called “white pollution”, which is appalling, has still been vividly remembered; in particular, we should draw our attention to the similar situation in the production and application of other packaging materials. The pollution of river water system caused by sewage in the papermaking process cannot be ignored. Therefore, we must pay great attention to environmental protection issues when we develop packaging.

The development of green packaging must be guided by the scientific concept of development.

The development of green packaging is a systematic project that requires scientific planning and scientific organization and implementation of new achievements in scientific and technological progress in order to achieve the desired results.

In the treatment of environmental pollution caused by disposable foamed polystyrene tableware, Shanghai has taken the lead in making significant progress in the country, achieving a harmless treatment and achieving a recycling rate of more than 70%. The main experience is: Based on the advanced experience of foreign countries, through the coordination organization of the Waste Management Office of Shanghai, the disposable foamed polystyrene tableware production unit will invest (3 cents for each tableware management fee). Responsible for recycling; set up processing workshops in sewage treatment plants to undertake regeneration tasks; digest and use advanced technologies for reclaiming waste foam plastics in Taiwan, and rely on the production capacity of wastewater treatment plants to dispose of disposable foam polystyrene tableware The sewage generated during the regeneration process is harmlessly treated. This is a typical case of success and can be used for reference and promotion.

The development of green packaging must involve the participation of enterprises, society and the government.

In the case of Shanghai's success, we have already mentioned the role of governments and companies in handling packaging waste and promoting green packaging. It must also be pointed out that the strong support of society is also essential. If Shanghai has a high awareness of environmental protection and there is no strong support from the society, people will use post-packaged waste to throw it away. It is unthinkable to achieve good results in the disposal of packaging waste. Therefore, we must also emphasize the joint participation of enterprises, society, and the government. Otherwise, the greening of packaging materials will be difficult to do well.

The development of green packaging can achieve a double harvest of social and economic benefits.

In the development of green packaging, there often arises conflicts between social and economic benefits. Some people mistakenly believe that the development of green packaging and the economic benefits of enterprises is an irreconcilable conflict. Therefore, some enterprises are motivated to develop green packaging. Not high, some paper mills prefer to pay for the wastewater sewage treatment without serious treatment of sewage and other phenomena. In fact, as long as we are willing to work hard and rationally apply the achievements of science and technology, we are entirely possible. When developing green packaging, we must also obtain good social benefits and good economic benefits.

Kunshan Baolv Plastic Resources Recycling Co., Ltd. has been investing in the operation of recycling disposable foamed polystyrene cutlery in recent years. The transition to a phase that has already produced considerable economic benefits has already reached a profit of more than 1 million yuan in 2004. This is a convincing case. Also in the production of composite flexible packaging materials, if we use solvent-free composite alternative dry composite, it may also have good social benefits and good economic benefits.
