The recycling method of circular colored copperplate label paper

The recycling method of circular colored copperplate label paper mainly includes the following steps:

1、 Classification collection

Firstly, it is necessary to classify and collect the discarded circular colored copperplate label paper. Due to the fact that label paper is often mixed with other waste paper, careful sorting is required to ensure the purity of the recycled material. This step is crucial for the subsequent recycling process.

2、 Preprocessing

Before recycling, it is necessary to preprocess the label paper. This includes removing impurities such as glue and ink from the label paper, as well as cutting it into sizes suitable for recycling. The preprocessing process may vary depending on the actual situation of the label paper and the requirements of the recycling equipment.

3、 Remove adhesive material

The recycling of waste copperplate paper, especially the adhesive introduced during the coating process, is a complex and critical issue. The main methods for handling these adhesives are mechanical, biological, and chemical methods.

Mechanical method: Removing adhesive substances through physical means such as grinding, screening, etc. But this method requires a large investment and is highly dependent on equipment.

Biological method: using the decomposition effect of microorganisms to remove adhesive substances. This method requires strict environmental conditions and is time-consuming.

Chemical method: Adding adhesive control agents to the pulp to dissolve, disperse, or reduce its viscosity, and then adsorbing onto the fibers and being fed into the paper, thereby separating from the pulp system and white water system. Chemical methods have great potential and promising prospects in the field of adhesive control due to their advantages of simplicity, speed, and low investment.

4、 Recycling and Utilization

After pre-treatment and removal of adhesive, the circular colored copperplate label paper can be sent to paper mills for recycling. During the papermaking process, these waste papers will be repurposed and papermaking will ultimately produce new paper products.

5、 Other uses

In addition to being used as a raw material for papermaking, circular colored copperplate label paper can also be used to make handmade artworks, seals, decorative paintings, etc. These uses not only help reduce the generation of waste paper, but also contribute to environmental protection.

6、 Precautions

In the process of recycling, it is necessary to ensure that the operation complies with environmental regulations and standards, and avoid causing secondary pollution to the environment.

The recycled circular colored copperplate label paper should undergo strict quality testing to ensure that it meets the requirements for recycling.

Encourage the public to actively participate in waste paper recycling activities, improve waste paper recycling rates, and reduce resource waste.

In summary, the recycling methods for circular colored copperplate label paper include multiple steps such as classified collection, pretreatment, removal of adhesives, recycling, and other uses. Through scientifically effective recycling methods, we can achieve resource recycling, reduce environmental pollution, and contribute to sustainable development.
