What are the requirements for the application of color copperplate label paper in food packaging?

The application of color copperplate label paper in food packaging has the following main requirements:

First, security requirements

1.Comply with food safety standards: color plate label paper must meet the national or regional safety standards for food contact materials, such as China's GB4806.1-2016 "Food contact materials Part 1: General requirements" and GB9685-2016 "Food contact materials and products in the use of restricted substances". These standards set maximum limits for hazardous substances that may migrate from food contact materials to ensure food safety.

2.Non-toxic and harmless: the ink, adhesive and other materials used in the production process of the label paper must be non-toxic and harmless, and will not migrate harmful substances to the food, so as to ensure the safety of the food in the storage and transportation process.

Second, functional requirements

1.Clear and accurate information: color copperplate label paper needs to clearly and accurately print the name of the food, ingredients, production date, shelf life, storage conditions and other important information for consumers to understand and use.

2.Moisture-proof and oil-proof: Although ordinary color coated paper may not have excellent moisture-proof and oil-proof performance, in some specific food packaging, it may be necessary to choose specially treated coated paper or use it in combination with other materials to improve the moisture-proof and oil-proof performance of the label paper and protect the food from the external environment.

3.Scratch resistance: The label paper needs to have a certain scratch resistance to ensure that the information on the label will not be blurred or fall off due to friction during transportation, storage and use.

Third, aesthetic requirements

1.Bright color: The color coated paper has a good printing effect, can print a bright color, clear pattern label, enhance the visual appeal of food packaging.

2.Reasonable design: The design of the label needs to conform to the characteristics of the product and the brand image, while making it easy for consumers to identify and read the information.

Fourth, environmental protection requirements

1.Recyclability: With the enhancement of environmental awareness, the recyclability of food packaging materials has been paid more and more attention. The recyclability of colored copper label paper should be considered in the design and production process, so that effective resource recovery can be carried out after waste.

2.Environmentally friendly materials: Encourage the use of environmentally friendly materials to make label paper, such as degradable materials or recycled materials, to reduce pollution to the environment.

In summary, the application of color copperplate label paper in food packaging needs to meet the requirements of safety, functionality, aesthetics and environmental protection. When choosing and using color label paper, enterprises should fully consider these factors to ensure the safety and reliability of food packaging.
