How to recycle or dispose of PET matte silver label paper after use?

The recycling or disposal of PET matte silver label paper after use mainly follows the following steps and principles:

1、 Recycling methods

Physical recycling:

Separation of impurities: Firstly, it is necessary to separate the impurities (such as paper, glue, ink, etc.) from the PET matte silver label paper. This can be achieved through mechanical methods such as hydrocyclones, airflow separators, and other equipment.

Crushing and granulation: Crushing the separated PET material into flakes or granules for subsequent processing and utilization.

Purification treatment: In order to obtain purer PET material, further purification treatment can be carried out, such as washing, drying, etc.

Chemical recycling:

Depolymerization reaction: PET material is depolymerized into monomers or oligomers using a specific catalyst at a certain temperature and pressure. These monomers or oligomers can be reused for the production of PET materials or other chemicals.

Recycling and reuse: After depolymerization, monomers or oligomers can be re synthesized into PET resin through specific processes, which can be used to produce new PET products and achieve resource recycling.

2、 Principles of handling

Classification collection: In order to ensure the recycling efficiency and quality of PET matte silver label paper, it should be classified and collected together with other types of waste.

Environmental protection treatment: In the process of recycling and disposal, environmental protection principles should be followed to avoid polluting the environment. For example, pollution-free or low pollution recycling technologies and equipment should be adopted, and the waste and wastewater generated during the recycling process should be properly treated.

Resource utilization: Recycled PET materials should be converted into valuable resources as much as possible to achieve maximum resource utilization. This can be achieved by improving recycling technology and enhancing the quality of recycled materials.

3、 Practical application

In practical applications, many countries and regions have established comprehensive PET recycling systems. These systems include recycling stations, sorting centers, processing plants, and other components that can efficiently recycle and process PET waste. At the same time, some companies are also committed to researching and promoting advanced PET recycling technologies and equipment to improve recycling efficiency and quality.

4、 Precautions

Avoid mixing with other materials: During the recycling process, it should be ensured that PET matte silver label paper is not mixed with other types of waste to avoid affecting the quality and reuse value of the recycled materials.

Choose legitimate recycling channels: In order to ensure that the recycled PET materials can be properly processed and utilized, it is necessary to choose legitimate recycling channels and recycling enterprises.

Strengthening publicity and education: In order to enhance public awareness and participation in environmental protection, it is necessary to strengthen the publicity and education work on PET recycling. This can be promoted through various channels such as media, community activities, school education, etc.

In summary, the PET matte silver label paper after use can be recycled through two methods: physical recycling and chemical recycling. In the recycling process, environmental protection principles and resource utilization principles should be followed to ensure the quality and reuse value of recycled materials. At the same time, it is also necessary to strengthen publicity and education work to enhance public awareness and participation in environmental protection.
