Improving the recyclability and degradability of tag coated paper is an important topic under the current environmental protection trend. Here are a few possible strategies:
First, improve recyclability
1. Use of high quality raw materials:
Use easy to recycle chemical wood pulp and other high quality raw materials to make tag coated paper, reduce the content of impurities, improve the recovery rate.
2. Optimization design:
Optimize tag design, reduce unnecessary coating and additive use, and make the recycling process simpler and more efficient.
3. Clear recycling identification:
Recycling labels and recycling information are clearly marked on the tag to guide consumers to correctly classify them and improve the recovery rate.
4. Establish a recycling system:
Cooperate with recycling enterprises to establish a sound recycling system to ensure that the tag coated paper can be effectively recycled and processed.
5. Promote environmental protection:
Strengthen environmental publicity, improve consumers' awareness of environmental protection and recycling, and promote the recycling of tag coated paper.
Second, improve degradability
1. Use of bio-based materials:
Bio-based materials are developed to replace part or all of the traditional chemical raw materials and improve the degradability of the tag coated paper. For example, natural polymer materials such as starch and cellulose are used as coating layers or additives.
2. Improve the production process:
Optimize the production process, reduce the emission of harmful substances, and reduce the environmental pollution of the tag coated paper. At the same time, new coating and drying technologies are explored to reduce the impact of the coating on the degradation performance.
3. Additive modification:
Research and development of additives with the function of promoting degradation, and add them to the tag coated paper to accelerate its degradation process in the natural environment.
4. Accelerated degradation technology:
Research and development of accelerated degradation technologies, such as biological enzymatic hydrolysis, photocatalytic degradation, etc., in order to shorten the degradation cycle of branded coated paper in the natural environment.
5. Classification management and processing:
Strengthen the classification management and treatment of waste tag coated paper to avoid mixing other non-degradable substances, affecting its degradation performance. At the same time, appropriate treatment methods such as landfill, incineration or biological decomposition are adopted to accelerate the degradation process.
It should be noted that due to the high strength and coating protection of coated paper itself, its degradability is relatively poor. Therefore, while improving degradability, it is also necessary to weigh the relationship between its use performance and environmental requirements. In addition, with the continuous progress of environmental protection technology and the increasingly strict environmental protection policies, the recyclability and degradability of tag coated paper are expected to be further improved in the future.
