How to handle LFGB testing for metal materials as food contact materials

The materials that come into contact with food during normal use are called food contact materials. Food contact materials can be classified according to different materials. Metal food contact materials refer to food contact materials of metal materials, such as food packaging, tableware, kitchenware, etc.

Food contact materials are related to environmental protection and human health, and we must pay attention to it. So far, the world has a relatively systematic and comprehensive control of tamper-evident materials. The European Union has relevant inspection regulations for tamper-evident materials, and the United States has FDA. Testing, Germany has LFGB testing and so on.

Some conventional items of LFGB testing for metallic contact materials are: sensory requirements, total migration, potassium permanganate consumption, heavy metals (calculated as Pb)

Specific migration:

Migration of heavy metals such as lead (Pb), cadmium (Cd), chromium (Cr), nickel (Ni), arsenic (As), antimony (Sb), zinc (Zn), etc.; formaldehyde, phenol, aromatic amine, vinyl chloride, partial Migration/residual amount of ethylene dichloride, styrene, acrylonitrile, caprolactam, bisphenol A, plasticizers (phthalates: DEHP, DINP, DNOP, DBP, DMP, DEP), etc.

EU Food Contact Material LFGB Testing and Product Regulations:

The EU food contact system’s framework regulation is (EC) No 1935/2004, which has been developed to date, covering plastic [(EU) No 10/2011], regenerated cellulose film [2007/42/EC], ceramics [84/500/ EEC], rubber [93/11/EEC], active and smart materials [(EC) No 450/2009] and other materials. In addition, some European countries such as Germany, Italy, France, and the United Kingdom also have their own unique food contact material systems.

Recent status of EU food contact material regulations: EU Food Contact Plastic Materials and Products Regulation (EU) 10/2011 revised the migration limit of heavy metals

U.S. food contact materials and products requirements:

Substances used in food packaging materials in the United States are regarded as indirect additives and are included in the food additive safety regulatory system and are uniformly managed by the US Food and Drug Administration (FDA inspection). The requirements for food contact materials and products in the United States are mainly in the 21 CFR of the United States Federal Code.

Requirements for food contact materials and products in China:

In terms of materials, heavy metal detection food contact materials can be divided into the following categories: plastics, metals (including surface coatings), glass, ceramics, enamel, rubber, paper and plant fibers, bamboo and wood, etc.

Process for handling food contact material testing:

1. Project application-submit an application to the inspection agency supervision.

2. Document preparation-According to the requirements, the company prepares relevant certification documents.

3. Product testing-the company sends samples to be tested to the laboratory for testing.

4. Compilation report-The certified engineer compiles the report based on the qualified test data.

5. Submit for review-the engineer will review the complete report.

6. Issuing a certificate-after the report is verified, the report will be issued.
