What does the application of thermal label paper in the food industry need to pay attention to?

In the application of thermal label paper in the food industry, the following aspects need to be paid attention to to ensure food safety, the accuracy of label information and compliance:

First, material safety

1.Thermal coating components: The thermal coating of thermal label paper contains chemical components, such as bisphenol A, which will chemically react to produce color at high temperatures. Although the content of BPA in thermal paper is usually very low and does not cause direct harm to the human body under normal use, it is still necessary to pay attention to its potential effects and try to choose products with low BPA A or no BPA.

2.Backing paper and adhesive: The material of backing paper and adhesive should be non-toxic and harmless to ensure that harmful substances will not be released when in contact with food.

Second, label content accuracy

1.Content requirements: The text and numbers that must be marked on the food label should be clear and conspicuous, and comply with the requirements of relevant laws and regulations. The label should be clearly marked with food name, ingredient list, net content, production date, shelf life, producer name and address and other information.

2.Authenticity and compliance: Label content must be true and accurate, without false or misleading information. At the same time, the provisions of relevant laws and regulations such as the Food Safety Law should be complied with to ensure the compliance of labels.

Third, durability and applicability

1.Waterproof and oil-proof performance: Food may encounter wet and greasy environments during processing, storage and transportation, so the heat-sensitive label paper should have good waterproof and oil-proof performance to ensure that the label information is clear and readable.

2.Temperature resistance: Some foods need to be stored in cold storage or frozen conditions, and thermal label paper should be able to maintain the stability and clarity of label information at these extreme temperatures.

3.Sticky stability: In cold and wet environments, the stickiness of the label may be affected. Therefore, thermal label paper with stable viscosity and not easy to fall off should be selected.

Fourth, printing and operation specifications

1.Print quality: Ensure that the printing device is in good condition and the print quality is clear and accurate to avoid blurring and gouging affecting the readability of the label information.

2.Operation specifications: During the operation, follow the relevant operation regulations to avoid label damage or incorrect information.

Fifth, environmental Protection and Sustainability

1.Recyclability: Choose recyclable thermal label materials to reduce the impact on the environment.

2.Reduce waste: reasonably plan the size and number of labels to avoid waste caused by overuse.

In summary, the application of thermal label paper in the food industry needs to pay attention to material safety, label content accuracy, durability and applicability, printing and operating specifications, environmental protection and sustainability and other issues. By strictly controlling these links, we can ensure the safe and effective application of thermal label paper in the food industry.
