How to evaluate the environmental performance of small roll thermal label paper?

Evaluating the environmental performance of small roll thermal label paper can be considered from the following aspects:

1、 Raw materials and production process

Raw material selection:

Evaluate whether thermal paper is made from renewable or recycled raw materials.

Check whether the raw materials contain substances harmful to human health or the environment.

Production process:

Understand whether environmentally friendly production processes and technologies are used in the production of thermal paper.

Assess whether a large amount of wastewater, exhaust gas, or solid waste is generated during the production process, and whether these wastes are properly disposed of.

2、 Chemical properties

Harmful substance content:

Use chemical analyzers and other equipment to detect the content of harmful substances such as heavy metals, formaldehyde, benzene, and bisphenol A in thermal paper, ensuring that the content of these substances meets environmental requirements.

Volatile Organic Compounds (VOCs):

Assess the VOCs content in thermal paper to ensure that it does not release excessive harmful gases during printing and use.

3、 Physical performance and durability

Light resistance:

Evaluate the durability of thermal paper under light conditions and determine its degree of fading in sunlight. This can be tested by exposing the paper to a light source and regularly checking for fading.

Water resistance:

Test the performance of thermal paper after immersion in water and evaluate its waterproof performance. This can be tested by soaking the paper in water and observing its deformation and fading.

Temperature resistance:

Test the stability of thermal paper in high and low temperature environments. This can be tested by placing paper in high and low temperature environments and observing its performance changes.

Tensile strength and tear strength:

Measure the tensile strength and tear strength of thermal paper using a tensile testing machine and a tear testing machine to ensure its durability during printing and use.

4、 Thermal performance and printing quality

Thermal sensitivity:

Evaluate the reaction speed of thermal paper to the thermal head to ensure that it can work properly at the specified temperature of the thermal head.

Color rendering speed and clarity:

Check the color development speed and clarity of thermal paper by printing test samples.

Thermal storage:

Evaluate the printing performance of thermal paper after long-term storage to ensure that its printed information can be preserved for a long time.

5、 Recycling and Reuse

Recyclability:

Evaluate whether thermal paper is easy to recycle and reuse. This includes the difficulty and cost of processes such as paper separation, crushing, and ink removal.

Recycling rate:

Understand the recycling rate of thermal paper, which refers to the proportion of recycled paper that can be reused to produce new paper.

6、 Environmental certification and standards

Environmental certification:

Check if the thermal paper has obtained relevant environmental certifications, such as FSC (Forest Stewardship Council) certification, ISO 14001 environmental management system certification, etc.

Compliant with standards:

Evaluate whether thermal paper meets the environmental standards and requirements set by the country or industry.

In summary, evaluating the environmental performance of small roll thermal label paper requires consideration from multiple aspects. By comprehensively considering factors such as raw materials, chemical properties, physical properties, thermal sensitivity, recycling and reuse, as well as environmental certification and standards, the environmental performance of thermal label paper can be comprehensively evaluated, and strong support can be provided for its application in the field of environmental protection.
