There are some restrictions and requirements on the application of self-adhesive coated paper in food packaging, which mainly revolve around food safety, label performance and regulatory compliance. The following is a detailed analysis of these limitations and requirements:
First, food safety requirements
1.Non-toxic and harmless: self-adhesive coated paper and its adhesive must ensure that it is non-toxic and harmless, and will not migrate harmful substances to food to ensure the safety of food. This requires labelling materials to comply with national standards and regulations related to food safety.
2.Temperature resistance: Food may experience temperature changes during processing, storage and transportation, so the self-adhesive coated paper needs to have a certain temperature resistance to ensure that the label will not fall off or deform in a high or low temperature environment, and will not release harmful substances.
Second, label performance requirements
1.Adhesive coated paper must be able to firmly adhere to food packaging materials, not easy to fall off, to ensure the integrity and traceability of label information. At the same time, the adhesion also needs to be moderate to avoid damage to the packaging material when removing the label.
2.Water and oil resistance: Food packaging may come into contact with moisture and grease during storage and transportation, so the self-adhesive coated paper needs to have good water and oil resistance to maintain the clarity and integrity of the label.
3.Printing effect: self-adhesive coated paper needs to have a good printing effect, and can clearly and accurately print out the relevant information of food, such as production date, shelf life, ingredients, etc. At the same time, printing inks also need to meet food safety requirements.
Third, regulatory compliance requirements
1.Label content specification: The label content on food packaging must comply with the requirements of relevant laws and regulations, including but not limited to product name, production date, shelf life, net content, ingredient list, nutrition list, manufacturer information, etc. Self-adhesive coated paper, as a label material, needs to be able to clearly carry this information.
2.Label size and position: The size and position of the label also need to meet the requirements of the relevant regulations. For example, in some countries or regions, the nutrition facts list on food packaging needs to occupy a certain space, and the font size is also clearly defined. Self-adhesive coated paper needs to be customized and designed according to these requirements.
Fourth, other restrictions and requirements
1.Environmental protection: With the improvement of environmental awareness, self-adhesive coated paper also needs to be environmentally friendly. This requires label materials to have as little impact on the environment as possible during production, use and disposal.
2.Cost considerations: The cost of food packaging is also one of the factors that enterprises need to consider. As a label material, the cost of self-adhesive coated paper needs to be controlled within a reasonable range to ensure the overall cost competitiveness of food packaging.
In summary, the application of self-adhesive coated paper in food packaging needs to meet the restrictions and requirements of food safety, label performance and regulatory compliance. When selecting and using self-adhesive coated paper as food packaging label materials, enterprises need to consider these factors comprehensively to ensure the quality and safety of food packaging.
