The coating of colored thermal label paper is usually safe under normal usage conditions. The following is a detailed analysis of its security:
1、 Coating composition
The coating of colored thermal sensitive label paper is mainly composed of thermal sensitive pigments (such as colorless dyes, phenols or other acidic substances), polymers, and other additives. These components undergo chemical reactions when heated, resulting in color changes. During normal use, these chemicals will not release harmful substances to the human body.
2、 Security assessment
Low toxicity: Some chemicals, such as bisphenol A, may be present in the coating, although they have some toxicity, their levels are usually within a safe range acceptable to humans. There has been no international discovery of poisoning caused by the normal use of thermal paper (including colored thermal label paper).
Skin contact: For most people, short-term exposure to the coating of colored thermal label paper does not cause skin discomfort. However, individuals with sensitive constitutions may develop allergic reactions to these chemicals. Therefore, it is recommended to take appropriate protective measures during use, such as wearing gloves.
Risk of accidental ingestion: If colored thermal label paper is accidentally ingested, it may cause discomfort. Therefore, it should be ensured to store it out of reach of children and avoid putting it in their mouths.
3、 Usage suggestions
Follow the correct operating method: When using colored thermal label paper, follow the correct operating method to avoid prolonged skin contact or putting it in the mouth.
Choose high-quality products: When purchasing colored thermal label paper, choose reputable brands and suppliers to ensure product quality and safety.
Proper disposal of waste: After use, colored thermal label paper should be properly disposed of in accordance with relevant regulations to avoid environmental pollution.
In summary, the coating of colored thermal label paper is safe under normal usage conditions. However, to ensure the safety of use, it is recommended that users follow the correct operating procedures, choose high-quality products, and dispose of waste properly. Meanwhile, for individuals with sensitive constitutions, additional protective measures should be taken during use.
