On the "Greenization" of Packaging Materials (II)

Second, the necessity of 'greening' packaging materials

1. The development of green packaging is a need to ensure safety and health and to protect people's health.

Food and pharmaceutical products are widely used in various kinds of packaging, many of which are also in direct contact with packaging materials. If the packaging does not meet the requirements of hygienic specifications, even if foods, drugs are strictly controlled in terms of formulation, production processes, etc. Because of the pollution of packaging, products will also cause harm to the human body. Therefore, we must attach great importance to the safety and hygienic properties of packaging materials.

2. The development of green packaging is the need to protect the natural environment, develop the domestic economy, and improve people's quality of life.

The natural environment is a necessary condition for us to survive. With the continuous development of science and technology, human influence on the natural world is increasing. On the one hand, people’s ability to develop and use natural resources is continuously improving. At the same time, human activities are likely to affect nature and human beings. The negative impact brought about by it has also been increasing, and some of these negative impacts cannot or cannot be eliminated in the short term. Therefore, we must pay more attention to environmental protection work, pay more attention to safety and health, and pay more attention to resource conservation. The many cases in China, such as the so-called 'white pollution' that resulted from the lack of attention paid to the disposal of plastic packaging materials and other wastes, and the pollution of industrial wastewater to river systems, have caused tremendous damage to our socialist construction. We should Learn profound lessons and vigorously carry out green packaging work to prevent the environmental hazards of packaging during its entire life cycle.

3. The development of green packaging is to participate in the fierce market competition in the world and break the need for trade barriers.

After our accession to the WTO, trade barriers between countries will gradually decrease. Instead, the so-called 'national treatment' promoted by the market economy will be used. In order to protect their own domestic market, industrialized countries will not be allowed to use higher tariffs, etc. Means, often through the threshold of increasing green packaging standards, restricting the entry of our goods, in order to meet the export demand of China's merchandise exports, we must also vigorously develop the green packaging industry to meet the needs of China's foreign trade.

4. The development of green packaging is a need to conserve resources and ensure the smooth development of China's socialist modernization.

Saving resources not only has universal significance for the sustainable development of human beings. For countries such as China, which have the largest population and relatively few resources in the world, saving resources is of even greater importance.

Third, the favorable conditions for 'greening' packaging materials

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 if the application volume is growing rapidly, once considered by people as "white. The main culprit of the pollution, plastic packaging materials that need to vigorously carry out 'green' work, there are many favorable conditions for the 'green' packaging.

The advantages of plastic packaging materials in terms of 'greening' can be summarized as follows:

1, plastic packaging materials may 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 control the monomer content, strictly control the selection and application of additives, and the hygienic properties of plastic packaging materials can be fully guaranteed;

2. Most of the large varieties of plastic packaging materials can achieve clean production and avoid environmental pollution;

3, plastic packaging materials, are basically thermoplastic plastics, can be heated and melted many times, with the ability to recover, recycling;

4. Most of them are flammable. Waste can also be treated by incineration and heat energy can be recovered.

5. The development and application of biodegradable plastics in recent years have 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 valuable experience in improving the adaptability of plastic packaging waste to environmental protection – the principles of 3R1D (ie, reduction, reuse, recycling, and development of biodegradable plastics). Practice has shown that these measures can be effective. Reduce pollution to the environment caused by waste plastic packaging materials entering the natural environment.

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