PET matte silver thermal paper has certain characteristics in terms of recycling and biodegradation. The following is a detailed analysis of its recyclability and biodegradability:


1、 Recyclability

The PET (polyethylene terephthalate) substrate in PET matte silver thermal paper is a widely used recyclable plastic. During the recycling process, PET materials can be recycled through a series of physical and chemical treatments such as melting, separation, purification, etc. This recycling and reuse method can not only reduce resource waste, but also lower the environmental pollution caused by landfill and incineration. Therefore, PET matte silver thermal paper is to some extent recyclable.


2、 Biodegradability

PET, as a high molecular weight polymer, is generally considered difficult to biodegrade in natural environments. However, in recent years, there has been some research on the biodegradability of PET both domestically and internationally, and some progress has been made. For example, certain specific microorganisms can degrade PET under certain conditions, converting it into components such as dihydroxyethyl terephthalate (BHET), monohydroxyethyl terephthalate (MHET), terephthalic acid (TPA), and ethylene glycol (EG). However, the biodegradation process of PET is usually slow and influenced by various factors such as light, temperature, microbial species and numbers. Therefore, the biodegradability of PET matte silver thermal paper is relatively limited.


3、 Comprehensive evaluation

Although PET matte silver thermal paper has certain advantages in recycling, there are still certain challenges in biodegradation. To improve its environmental performance, the following measures can be considered:

Improve recycling efficiency: By improving recycling technology and processes, the recycling efficiency of PET matte silver thermal paper can be increased, reducing resource waste.

Developing new biodegradable materials: researching and developing new biodegradable materials to replace traditional PET substrates and improve the biodegradability of label materials.

Strengthen environmental protection publicity and education: raise public awareness of environmental protection and sustainable development, encourage people to use environmentally friendly materials, and reduce waste and pollution.


In summary, PET matte silver thermal paper is somewhat recyclable, but its biodegradability is relatively limited. By taking a series of measures, its environmental performance can be further improved, achieving the recycling of resources and sustainable development of the environment.
