Food safety extends far beyond what’s inside the package—the packaging itself must meet rigorous safety standards to protect consumers. If you’re sourcing packaging from China or working with Chinese manufacturers, understanding their comprehensive food-grade safety requirements is essential for market access and consumer protection.
China enforces food-grade packaging standards through the GB 4806 series, a unified regulatory framework covering all food contact materials with specific migration limits, testing requirements, and mandatory Declaration of Compliance documentation that ensures materials don’t pose health risks to consumers.
Let’s explore these critical standards that determine whether your packaging can successfully enter global markets while maintaining the highest safety standards.
What Is the GB 4806 Series and How Does It Work?
China’s regulatory approach to food packaging represents one of the world’s most comprehensive systems, designed to protect consumers while facilitating international trade.
The GB 4806 series consists of over 15 interconnected national food safety standards established in 2016 under China’s Food Safety Law, covering all materials that directly or indirectly contact food including packaging, containers, utensils, machinery, inks, adhesives, and lubricants.
This framework creates a unified system that manufacturers, importers, and distributors must follow for legal market entry. Non-compliance results in serious consequences including product rejection at customs, mandatory disposal of goods, or complete market withdrawal.
The system governs five primary material categories:
- Plastics (GB 4806.7-2023) with enhanced requirements for aromatic compounds
- Metals (GB 4806.9-2023) prohibiting toxic heavy metals as alloy elements
- Paper and board (GB 4806.8) for traditional packaging materials
- Rubber materials (GB 4806.11-2023) with strict limits on harmful amines
- Composite materials (GB 4806.13) addressing multi-layer packaging complexity
Recent updates in 2023-2024 have strengthened these standards significantly. The latest revisions include new testing requirements for primary aromatic amines in plastics and complete prohibition of lead, cadmium, arsenic, mercury, antimony, beryllium, and lithium as alloy elements in metal materials.
What Are the Core Safety Principles Under GB 4806.1-2016?
The foundation of China’s food packaging safety rests on three fundamental principles that apply universally across all materials.
GB 4806.1-2016 establishes that food contact materials must not endanger human health through substance migration, must not alter food composition or sensory properties, and must minimize chemical substances while achieving intended functionality.
Migration Safety Requirements
Under recommended use conditions, substances migrating from packaging into food must not pose health risks. The standard sets a strict limit: unapproved substances migrating into food should not exceed 0.01 mg/kg, ensuring comprehensive consumer protection.
Food Integrity Protection
Materials cannot cause changes to food composition, structure, or sensory properties including color, smell, or taste. They must not impart unintended technical effects to foods unless specifically authorized for functional purposes.
Chemical Minimization Principle
The quantity of substances used in food contact materials should be minimized while still achieving desired performance results. This principle drives innovation toward safer, more efficient packaging solutions.
| Safety Principle | Requirement | Compliance Measure |
|---|---|---|
| Migration Safety | ≤0.01 mg/kg for unapproved substances | Comprehensive migration testing |
| Food Integrity | No sensory or compositional changes | Organoleptic evaluation |
| Minimization | Lowest effective substance levels | Formulation optimization |
The standard also mandates that all substances comply with appropriate quality specifications and requires manufacturers to implement effective control systems for non-intentionally added substances (NIAS).
How Do Migration Testing Requirements Vary by Material Type?
Migration testing forms the scientific backbone of China’s safety assessment system, with material-specific protocols ensuring comprehensive evaluation.
Migration testing measures substance transfer from packaging materials into food simulants under controlled conditions that replicate real-world usage scenarios, with overall migration limits of 60 mg/kg of food or 10 mg/dm² of contact surface.
Overall Migration Testing Framework
China’s GB 31604.1-2015 establishes comprehensive testing protocols measuring total non-volatile substance migration. The system uses four primary food simulants: distilled water (aqueous foods), 3% acetic acid (acidic foods), 10% ethanol (alcoholic foods), and olive oil (fatty foods).
Specific Migration Limits (SML)
Individual substances have targeted migration limits based on toxicological assessments:
- Bisphenol A: 0.6 mg/kg maximum migration
- Dibutyl phthalate: 0.3 mg/kg maximum migration
- Primary aromatic amines: Strictly controlled with new testing requirements
Material-Specific Testing Protocols
Plastic Materials (GB 4806.7-2023)
Enhanced requirements now include total migration testing for primary aromatic amines in materials containing aromatic isocyanates or azo colorants. Testing conditions vary from 10 days at room temperature to 2 hours at 100°C depending on intended use.
Metal Materials (GB 4806.9-2023)
Focus on heavy metal migration prevention with complete prohibition of toxic elements as alloy components. Stainless steel, aluminum, and coated metals each follow specific testing protocols addressing corrosion resistance and coating stability.
Composite Materials (GB 4806.13)
Multi-layer packaging requires comprehensive evaluation of each layer and their interactions, including adhesive layers, barrier films, and structural components under various temperature and time conditions.
What Are the Revolutionary Changes in Adhesive Standards for 2025?
The introduction of GB 4806.15-2024 marks a historic milestone as China’s first comprehensive standard specifically addressing adhesives in food packaging applications.
GB 4806.15-2024, effective February 8, 2025, establishes China’s first dedicated adhesive standard after nearly a decade of development, featuring positive lists for approved substances and differentiated requirements based on food contact levels.
Groundbreaking Classification System
The standard revolutionizes adhesive regulation through a sophisticated classification approach:
Direct Contact Adhesives: Limited to 51 authorized base materials listed in Annex A, with the most restrictive migration limits and comprehensive safety evaluations required.
Indirect Contact Adhesives: Expanded to 341 authorized substances listed in Annex B, allowing greater formulation flexibility while maintaining safety oversight.
Technical Specifications and Requirements
The standard establishes comprehensive physicochemical specifications including:
- Overall migration limits tailored to contact type
- Potassium permanganate consumption limits
- Heavy metal restrictions and testing protocols
- Additive compliance with GB 9685 requirements
| Contact Classification | Authorized Substances | Migration Limits | Key Requirements |
|---|---|---|---|
| Direct Food Contact | 51 base materials (Annex A) | Strictest limits | Full toxicological data |
| Indirect Food Contact | 341 substances (Annex B) | Moderate limits | Risk-based assessment |
| Barrier-Protected | Risk-based evaluation | Contextual limits | Barrier effectiveness proof |
Implementation and Risk Management
Manufacturers must implement comprehensive risk control during formulation design, raw material selection, and production processes. User companies must minimize adhesive quantities and establish effective barrier layers where necessary.
How Do Chinese Standards Compare to Global Requirements?
China’s approach represents a sophisticated hybrid system that incorporates the best elements from major international regulatory frameworks while maintaining unique Chinese characteristics.
