What are the requirements for wax-based carbon strips in the food packaging industry?

The requirements of the food packaging industry for wax-based carbon belts are mainly reflected in the following aspects:

First, basic performance requirements

1. Print performance:

Printing density and clarity: The text and pattern printed out by the wax-based carbon tape are required to have high clarity and sharp edges to ensure that the information on the food packaging (such as production date, shelf life, ingredient list, etc.) is easy to identify and read.

Printing stability: In the continuous printing process, the performance of the carbon strip is required to be stable, and it is not easy to break the tape, curl and other phenomena to ensure production efficiency and product quality.

2. Wear and scratch resistance:

Food packaging may be subjected to a variety of physical friction during transportation, storage and use, so it is required that the logo printed with wax-based carbon tape has good wear resistance and scratch resistance to maintain the persistence and integrity of the information.

3. Chemical resistance:

Food packaging materials sometimes need to contact grease, moisture and other chemical substances, so it is required that the wax-based carbon strip has a certain chemical resistance to prevent the logo from blurring or falling off after contact with these substances.

Second, security requirements

1. Non-toxic and harmless:

Since food packaging is directly in contact with food, it is required that the wax-based carbon belt and its printed label are non-toxic and harmless, meet food safety standards, and avoid contamination of food.

2. Compliance with regulations:

It is required that the wax-based carbon strip and its printed logo comply with relevant food safety regulations and standards at home and abroad, such as EU 1935/2004/EC of the European Union and FDA of the United States.

Third, adaptability requirements

1. Material adaptability:

There are many kinds of food packaging materials, including paper, plastic film, etc. It is required that the wax-based carbon belt can adapt to different materials of food packaging materials to ensure that high-quality logos can be printed on various materials.

2. Environmental adaptability:

Under different environmental conditions such as temperature and humidity, wax-based carbon strips are required to maintain stable printing performance to ensure that the information on food packaging can be clearly read in different environments.

Fourth, economic requirements

1. Cost effectiveness:

The food packaging industry is more sensitive to cost, so it requires wax-based carbon strips to have better cost effectiveness under the premise of ensuring print quality and safety, so as to reduce the production cost of enterprises.

In summary, the requirements for wax-based carbon belts in the food packaging industry cover many aspects such as basic performance, safety, adaptability and economy. These requirements need to be considered in the selection and use of wax-based carbon strips to ensure that the information on food packaging is accurate, clear, durable and safe.
