Thermal paper (thermal paper) has been widely used in the printing fields of receipts, invoices and labels, but the question of whether thermal paper can be recycled has raised some questions. This article will explore this issue to help you understand the recyclability of thermal paper, and provide relevant suggestions.
First, let’s take a look at the composition of the thermal paper. Thermal paper consists of two main layers: the bottom layer is the paper substrate, while the top layer contains heat-sensitive chemicals, which are heated to produce images or text. Due to the special structure of thermal paper, it is different from traditional paper, which also makes some challenges in its recovery process.
In general, thermal paper is not suitable for recycling together with ordinary paper. The main reasons are given as follows:
The top chemical of thermal paper:
The top layer of thermal paper contains thermal sensitive chemicals, which is usually the source of the image after heating. These chemicals may negatively affect the quality of recycled paper and the processing process.
Paper matrix separation from the top layer:
During the thermal paper recovery process, the paper matrix usually needs to be separated from the chemical substance on the top layer. This separation process requires special treatment and techniques that increase the complexity and cost of recovery.
However, despite the difficulties in recycling the thermal paper itself, there are still some feasible solutions and precautions:
Screening in paper recycling:
When recycling the paper, the thermal paper can be separated from the ordinary paper through the screening process. This ensures the quality and treatment effect of the recycled paper.
Look for special recycling channels:
some special recycling channels may accept thermal paper and recycle it through special processing methods. You can consult a local recycling centre or recycling company to see if such channels exist.
Reducing the use of thermal paper: In order to achieve environmental protection and sustainable development, reducing the use of thermal paper is an important direction. You may consider using electronic receipts, electronic labels, or other alternatives to reduce the need for thermal paper.
