Food-Safe Packaging Adhesives: Compliance Requirements for Corrugated Boxes

When corrugated boxes are used for food packaging—whether direct contact or secondary packaging—the adhesive must meet specific safety requirements. Understanding these regulations is essential for serving food industry customers.

Why Food Safety Matters for Adhesives

Even in secondary packaging (boxes around wrapped food), adhesive components can potentially

Migrate through paper into food products

Transfer via direct contact during handling

Release volatile compounds into enclosed spaces

Contaminate food through damaged packaging

Major Regulatory Frameworks

United States (FDA)

FDA 21 CFR 175.105: Adhesives

FDA 21 CFR 176.170: Components of paper and paperboard in contact with aqueous and fatty foods

FDA 21 CFR 176.180: Components of paper and paperboard in contact with dry food

GRAS (Generally Recognized as Safe) status for ingredients

European Union

Framework Regulation EC 1935/2004: General requirements for food contact materials

Regulation EC 2023/2006: Good Manufacturing Practice

National regulations (e.g., BfR recommendations in Germany)

Specific migration limits for certain substances

Other Markets

China: GB 9685 (Hygienic Standard for Uses of Additives in Food Containers)

Japan: JHOSPA (Japan Hygienic Olefin and Styrene Plastics Association) positive lists

Brazil: ANVISA regulations

Many countries follow FDA or EU standards

Starch Adhesive Compliance

Good News: Traditional starch-based corrugating adhesives are generally food-safe

Starch is GRAS (corn, tapioca, potato)

Water is obviously safe

Borax in small quantities is acceptable

Potential Issues

Caustic soda residue (typically not a problem at normal levels)

Biocides/preservatives (must be food-safe approved)

Cross-linking agents in water-resistant formulas

Formaldehyde (avoid for food packaging)

Formaldehyde-Free Adhesives

Some traditional paper adhesives (especially for paper tubes, corner protectors) historically contained formaldehyde. For food applications

Specify formaldehyde-free adhesive

Request certificates of compliance

Xuegong's formaldehyde-free series specifically designed for food packaging

Documentation Requirements

To serve food packaging customers, you need

1. Declaration of Compliance

Statement that adhesive meets specific regulations

List of applicable standards (FDA, EU, etc.)

Signed by responsible party

2. Technical Data Sheet

Complete composition (may be generic)

Manufacturing process

Intended use conditions

3. Migration Testing (if required)

Overall migration limits

Specific migration limits for restricted substances

Testing conditions and food simulants

4. Traceability Records

Batch identification

Raw material sources

Production records

Best Practices for Food Packaging
