What are the relevant industry standards for colored thermosensitive synthetic paper?

Color thermal sensitive synthetic paper, as a special paper material, has various industry standards covering multiple aspects to ensure its quality and usability. Here are some industry standards related to color thermal sensitive synthetic paper:

1、 National standards

GB/T 28210-2011 Thermal Paper

This standard specifies the technical requirements, test methods, inspection rules, as well as requirements for marking, packaging, transportation, and storage of thermal paper. Although mainly aimed at thermal paper, colored thermal synthetic paper, as a type of thermal paper, should also comply with or refer to this standard.

Other relevant national standards

Standards such as SJ/T 11438-2015 "General Specification for Commercial Roll Thermal Paper in Information Technology" may require specific uses or properties of colored thermal synthetic paper.

2、 Industry standards

YZ/T 0148-2015 Express Electronic Waybill

This standard proposes specific technical requirements for electronic waybills for express delivery, including paper materials, printing performance, information protection, and other aspects. Although mainly aimed at electronic waybills for express delivery, the paper material requirements may be applicable to the application of colored thermal sensitive synthetic paper in similar fields.

Other relevant industry standards

Standards such as TY/T 3902-2019 "Technical Requirements and Inspection Methods for Sports Lottery Special Thermal Paper" may provide specific technical requirements for thermal paper in specific fields.

3、 Environmental and safety standards

RoHS directive

The RoHS directive restricts the use of certain hazardous substances in electronic and electrical equipment. Although colored thermosensitive synthetic paper itself does not belong to electronic and electrical equipment, if it is used as a label or packaging material for electronic equipment and comes into direct contact with electronic equipment or may have an impact on its environment, it may need to comply with the requirements of the RoHS directive.

China environmental labeling product certification

The China Environmental Labeling Product Certification is the only environmental product certification mark authorized by the Chinese Ministry of Ecology and Environment, indicating that the product meets specific environmental protection requirements during production, use, and disposal processes. Color thermal sensitive synthetic paper can apply for and obtain this certification if it meets relevant environmental standards.

Bisphenol a restriction

Bisphenol A is a type of estrogenic substance that is carcinogenic and can enter the body through the skin to interfere with and disrupt the endocrine system. Some countries and regions have imposed restrictions and monitoring on the use of bisphenol A in thermal paper. If colored thermosensitive synthetic paper contains bisphenol A, it should also comply with relevant limit standards.

4、 Other standards and requirements

Physical performance indicators

Including the basis weight, thickness, tensile strength, tear resistance, etc. of the paper, these indicators ensure the basic usability of the paper.

Chemical performance indicators

It mainly involves the water resistance, oil resistance, acid and alkali resistance of paper to ensure its stability and durability in different environments.

Printing performance indicators

Require paper to have good color rendering, clarity, and preservation during the thermal printing process. This includes specific indicators such as print density, print clarity, and image retention.

Other specific requirements

Requirements such as image retention rate, waterproof and oil resistant performance may vary depending on specific application scenarios.

In summary, the relevant industry standards for colored thermal sensitive synthetic paper cover multiple aspects, including national standards, industry standards, environmental and safety standards, as well as other standards and requirements. These standards together constitute the quality assurance system for color thermal sensitive synthetic paper, ensuring that it can perform at its best in various fields and meet different printing needs.
