Fifth, some issues that need attention in the 'greening' of packaging materials

1. Further strengthen environmental protection promotion work and raise people's awareness of environmental protection

The 'greening' of packaging is a huge system project. It involves all aspects and involves every specific person. Without the attention of the whole society and the active participation of the broad masses of people, it is absolutely impossible to do so despite the recent Over the past years, we have carried out many publicity campaigns on green packaging, and we have achieved certain results in raising people's awareness of environmental protection. However, we cannot be satisfied with the status quo and we must further strengthen publicity for a long time to come. In order to make the general public's awareness of environmental protection, there is a tremendous improvement.

2. Improve regulations and strengthen supervision

As mentioned earlier, green packaging involves many aspects. Some of them can be promoted through the supervision of the broad masses of the people and society through the improvement of the awareness of the broad masses of the people. However, an equally large part is the safety and hygiene of packaging. Problems can only be achieved by testing the test data of the organization and the relevant laws and regulations and standards, so that correct conclusions can be drawn. Therefore, improving regulations and strengthening supervision has an irreplaceable role in the development of green packaging.

3. Pay attention to clean production work

As mentioned earlier, many packaging materials such as plastic packaging have the potential to achieve clean production. For example, in the production of composite flexible packaging materials that are widely used, coextrusion compounding, extrusion compounding (rogue compounding), and solvent-free are present. Compounding, etc. cleans up the production process, but at present, in the production of composite flexible packaging materials, a large number of dry compounding processes using solvent-based adhesives are used. We should, through painstaking efforts, transform the production of composite flexible packaging and other materials into clean production as soon as possible. In the process.

4. The general collection of packaging waste management fees for packaging material production units

The overwhelming majority of the packaging of goods is a one-time use. After the goods are opened to consumers, they become waste, and the harmless and resourceful disposal of packaging waste is of great significance. Therefore, the author suggests that, in the treatment of packaging waste, draw lessons from the successful experience of foreign countries, adhere to the principle of whoever produces and who is responsible for governance, and collect a disposal fee for packaging waste on the basis of the production volume of packaging materials. The reason is as follows:

(1) The development of the harmless and resourceful treatment of packaging waste requires sufficient economic support. Otherwise, it cannot be carried out. Even after a productive job, it has good social benefits and good economic benefits. The initial implementation of the project often requires a lot of investment.

(2) The use of packaging materials has a wide range, and the processing of packaging waste is naturally very large. If the costs are all packaged by the state, it will be difficult for the government to raise enough funds in the near future.

(3) The unit that produces packaging materials, and the disposal fee for the delivery of packaging waste, will have an increase in the production cost, and may even cause a slight price adjustment for a small amount of packaging materials. However, as long as it is reasonable and economical in the design and material selection of packaging, Against the principle of over-packaging, the packaging costs of commodities will not exceed the social affordability.

(4)Adjustment of the proportion of packaging waste disposal fees (Packaging waste has no negative impact on the environment and has a negative impact such as degradable plastics, and less disposal of packaging waste disposal fees [reducing the proportion of charges]; packaging waste is negative to the environment The impact of such as PVDC, overcharged packaging waste disposal fees [to increase the proportion of charges]) to support the development of environmentally friendly packaging materials.

In addition, the surplus part of the packaging waste disposal fee can be used as a special environmental protection fund for packaging, which can be used for scientific research on green packaging, and the promotion of research results, and promote the development of green packaging.

5, make a good use of packaging waste in the macro planning work

The use of packaging waste can often be achieved in a variety of ways. For example, some of the packaging wastes can be reused as material resources, and can also be used for incineration and recovery of heat energy for power generation. In this case, it is of special significance for the relevant government departments to do a good macro-planning. . It is understood that some regions currently promote the recycling of plastic packaging waste on the one hand, and on the other hand, they add oil and coal to the combustion furnace of a waste power plant to increase heat energy. This practice is very inappropriate.

It is recommended that in areas with high standards of living such as the southeastern coastal areas where the content of flammable materials is large, the disposal of general plastics and paper products in packaging waste should be carried out in a manner that builds waste power plants and recovers heat energy. For those areas where the content of combustibles in domestic garbage is relatively small, we strongly advocate recycling and recycling.
