What are the precautions for the use of mixed base carbon strips in the food industry?

When using a mixed base carbon strip in the food industry, the following aspects need to be noted to ensure the best performance of the carbon strip and food safety:

1. Choose the appropriate carbon belt specifications

Width and length: According to printing requirements and equipment requirements, choose the appropriate width and length of carbon tape. The common mixed base carbon strip width is 40, 50, 60, 70, 80, 90, 110mm, etc., the length is 100, 300m, etc., and can also be customized according to demand.

Roll direction and axis: Confirm the roll direction (outer carbon, inner carbon) and axis size (such as 1 inch, 1/2 inch) of the carbon tape to ensure compatibility with the printing device.

2. Storage and transportation conditions

Storage environment: the mixed base carbon strip should be stored at -5 ° C to 40 ° C, relative humidity of 20% to 85%, and the storage time should not exceed one year. Avoid direct exposure of the carbon belt to sunlight and moisture to prevent damage.

Transportation environment: During transportation, the ambient temperature should be kept at -5 ° C to 45 ° C, the relative humidity between 20% and 85%, and the transportation time should be as short as possible, not more than one month.

3. Precautions during use

Temperature and humidity: When using a mixed base carbon strip, you should ensure that the temperature of the printing environment is between 5 ° C and 35 ° C, and the relative humidity is between 45% and 85% to obtain the best printing results.

Device compatibility: Ensure that the selected mixed base carbon tape is compatible with the printing device, including print head type, printing speed, etc.

Print quality monitoring: Regularly check the print quality to ensure that the carbon strip can be uniformly transferred during the printing process to avoid printing blur, broken lines and other problems.

Replacement and cleaning: According to the service life of the carbon belt (usually 3-6 months) and the change of print quality, timely replacement of the carbon belt. At the same time, regularly clean the printing equipment and keep it clean to extend the service life of the carbon belt and equipment.

4. Food safety considerations

Non-toxic and harmless: Ensure that the selected mixed base carbon belt is non-toxic and harmless, and will not pollute the food. When selecting carbon belts, attention should be paid to their environmental certification and production standards.

Avoid contact with food: Although the mixed base carbon strip itself may be non-toxic, it should be avoided from direct contact with food during use. Printed labels should be adequately dried and cured before use to reduce the impact of residues on food.

To sum up, when the food industry uses the mixed base carbon belt, it is necessary to comprehensively consider the specifications of the carbon belt, storage and transportation conditions, precautions during use, and food safety requirements, to ensure the printing effect, equipment life and food safety.
