Printing inks used on food packaging, labels and labels must meet certain standards to protect the health of consumers. But are inks really harmless in terms of food safety? This article will examine the safety and health impacts of inks used in food packaging.
What are the Inks Used in Food Packaging?
Inks used on food packaging and labels must meet certain standards. These inks are subject to rules set by the European Union (EU), the US Food and Drug Administration (FDA) and other international organizations. In general, inks used in areas that may come into contact with food are divided into the following types:
- Water-based inks: A greener and safer option.
- UV curable inks: Widely used in food packaging, but appropriate formulations are required.
- Solvent-based inks: May contain volatile organic compounds (VOCs) and should be used with caution.
- Plant-based inks: Developed to minimize their chemical content.
Are Inks Used in Food Packaging Harmful?
Some conventional printing inks may contain harmful chemicals. These substances can contaminate food and cause adverse effects on human health. Here are some of the ingredients that can be harmful to health:
- Aromatic amines: Potential to cause cancer.
- Phthalates: May disrupt hormone balance and affect reproductive health.
- Volatile Organic Compounds (VOC): May cause respiratory problems.
- Heavy metals (lead, cadmium, mercury): Can damage the nervous system.
Migration of these harmful substances from packaging to food can pose a major risk to consumer health.
Food Safety Certificates and Standards
Food contact packaging inks must comply with certain standards and certifications. Here are some of the certifications that stand out:
- FDA (American Food and Drug Administration)
- EU 1935/2004 Food Contact Substances Regulation
- Swiss Ordinance List Approval
- ISO 22000 Food Safety Management System
Inks with these certifications minimize the risk of contamination of food with harmful substances.
What to Consider When Choosing Food Safe Inks?
Consumers and producers should be aware of the inks used in food packaging. The following factors should be considered:
- Certified and tested inks must be used.
- The printing surface should be designed so that it does not come into direct contact with food.
- Vegetable-based and water-based inks should be preferred.
- Recyclable and environmentally friendly packaging inks should be selected.
Printing inks play an important role in food safety. Choosing the right inks plays a critical role in protecting the health of consumers. Inks used in food contact packaging must be certified, tested and comply with international safety standards.
By making more conscious choices about food safety, you can both protect consumer health and adopt an environmentally friendly approach.
