When using heat-sensitive labels, the food industry needs to pay attention to the following aspects to ensure the suitability, safety and compliance of the label:
1. Durability of the label
Waterproof and oil-proof performance: Because food packaging may be in contact with moisture, grease, etc., the three heat-proof label paper must have good waterproof and oil-proof performance to ensure that the label is still clear and readable in a wet or greasy environment.
Scratch-proof: Food may rub against each other during transportation and storage, and the label paper should have a certain scratch resistance to prevent the information on the label from being worn.
2. Food safety
Non-toxic and harmless materials: The label paper should be made of non-toxic and harmless materials to avoid the release of harmful substances in contact with food or food packaging, which may affect food safety.
Compliance with food contact material regulations: Labels should comply with the requirements of relevant national and regional regulations on food contact materials, such as Regulation (EU) No 10/2011.
3. Information accuracy
High definition printing: The information on the label (such as production date, shelf life, ingredient list, etc.) should be legible so that consumers and regulatory authorities can accurately read it.
Anti-fading performance: The label paper should have good anti-fading performance to ensure that the information on the label is still clear and readable after a long time of storage.
4. Storage conditions
Appropriate temperature and humidity: the heat-sensitive label paper should be stored in a dry, cool place, avoid direct sunlight and high temperature environment to prevent aging or deterioration of the label paper.
Avoid contact with chemical substances: The label paper should avoid contact with chemical substances such as strong acids and alkali, so as to avoid chemical reactions that may cause damage to the label.
5. Print and paste
Print compatibility: Make sure that the printer used is compatible with the tri-thermal label paper for the best print results.
Timely pasting: The printed label should be pasted on the food package in time to avoid long-term exposure to the air leading to the label curling or viscosity reduction.
6. Regulations and standards
Comply with industry standards: Label paper should meet the relevant standards and regulations of the food industry, such as GB/T 28210-2011 "Thermal paper" and so on.
Regulatory requirements: Understand and comply with the specific requirements of local regulatory authorities on food labels, such as label content, format, and size.
To sum up, the food industry needs to comprehensively consider the durability, food safety, information accuracy, storage conditions, printing and pasting, and regulations and standards of the label when using the three heat-sensitive label paper to ensure the suitability, safety and compliance of the label.
