Adhesive labels play a vital role in food packaging, providing essential information like nutritional facts, expiration dates, and product branding. However, ensuring the safety of these labels is just as important as the food they accompany. Unsafe adhesives can compromise food quality and consumer health, making it critical to select the right labels for your packaging.
In this blog, we’ll explore the key aspects of choosing food-safe adhesive labels and provide practical guidance for businesses.
What Are Food-Safe Adhesive Labels?
Food-safe adhesive labels are specifically designed to comply with stringent food safety standards. These labels ensure that the adhesives used do not contaminate the food, especially when they come into direct or indirect contact with it.
The key characteristics of food-safe labels include:
- Non-toxicity: The adhesives are free from harmful chemicals like BPA and phthalates.
- Stability: They do not break down or leach substances when exposed to moisture, heat, or cold.
- Compliance: They meet regulatory standards such as FDA and European Union (EU) regulations for food packaging materials.
These labels are essential for maintaining product integrity and safeguarding consumer health.
What Adhesive Labels Are Used in Food Packaging?
The choice of adhesive for food packaging depends on the type of packaging material and its intended use. Each adhesive type has specific applications, and selecting the right one depends on factors like the food’s storage conditions and the packaging material.
Common types of adhesives include:
- Water-Based Adhesives: These are environmentally friendly and safe for indirect food contact. They are commonly used on paper or cardboard packaging.
- Solvent-Based Adhesives: Known for their durability, solvent-based adhesives are used for labels on glass or plastic surfaces. However, they require strict regulations to ensure food safety.
- Hot-Melt Adhesives: These adhesives are versatile and often used for food packaging due to their strong bond and quick-drying properties. They are suitable for both paper and plastic materials.

What Adhesive is Food-Safe?
Food-safe adhesives are those that meet regulatory standards for food packaging safety. These adhesives are rigorously tested to ensure they do not alter the food’s taste, smell, or quality.
Key examples include:
- FDA-Approved Adhesives: In the United States, adhesives that comply with FDA regulation 21 CFR 175.105 are considered safe for indirect food contact.
- EU-Compliant Adhesives: The European Food Safety Authority (EFSA) sets guidelines for adhesives used in food packaging, ensuring they do not release harmful substances.
- Global Certifications: Many adhesives also meet international standards like ISO 22000 for food safety management.
Is the Glue on Food Packaging Safe?
Not all glues used in food packaging are safe, which is why careful selection is crucial. To ensure safety, always choose adhesives tested for food contact applications and certified by reputable organizations.
Unsafe adhesives can:
- Leach harmful chemicals into the food, especially under high temperatures.
- Cause allergic reactions in sensitive individuals.
- Compromise the food’s shelf life by weakening the packaging.
What Are the 5 Key Requirements of Food Labels?
Adhesive labels must meet specific requirements to be effective and compliant. By meeting these requirements, adhesive labels help maintain transparency and trust with consumers.
The five key elements include:
- Ingredient List: Clearly list all ingredients, including additives and allergens.
- Nutritional Information: Provide details on calorie content, fats, sugars, and other nutrients.
- Expiration Dates: Ensure labels are durable enough to display clear expiration dates throughout the product’s shelf life.
- Storage Instructions: Include guidance on proper storage conditions to maintain food quality.
- Safety Compliance: Use materials and adhesives that comply with food safety regulations.
How Do Food-Safe Adhesives Differ from Other Types of Adhesives?
Food-safe adhesives differ significantly from general-purpose adhesives in their composition and application. Key differences include:
- Chemical Composition: Food-safe adhesives are free from toxins and harmful substances like volatile organic compounds (VOCs).
- Regulatory Standards: They are manufactured to meet food safety regulations, unlike standard adhesives.
- Performance: Food-safe adhesives are designed to withstand environmental factors like moisture and temperature changes without compromising safety.

What Certifications Should Food Packaging Labels Have to Ensure Safety?
Certifications are a reliable way to ensure the safety of food packaging labels. Important certifications include:
- FDA Approval: Ensures compliance with U.S. food safety standards.
- EFSA Certification: Confirms adherence to European regulations for food packaging materials.
- ISO 22000: Certifies that the adhesive manufacturer follows international food safety management practices.
- Migration Testing: Verifies that the adhesive does not release harmful substances into the food.
By choosing labels with these certifications, businesses can ensure the safety and quality of their food products and build customer trust.
