Food contact materials and products

Product Detail

Food contact materials and products

In recent years, food safety incidents occur frequently, and food borne diseases have caused serious consequences. Food safety has become the focus of most countries and people, especially food contact materials that are easy to be ignored. Guanding laboratory provides all-round testing services for food contact materials, especially thermosetting plastics, which meets the requirements and safety of modern people's life.

What is food contact material testing?

1、 Material category of food contact materials

According to the internationally accepted classification method, the materials and appliances in contact with food are divided into:

Rubber products, glass products, ceramic products, silica gel products, plastic products, metal products, paper products and wood products, etc.

The product categories include: food packaging materials, food containers and utensils, tableware and kitchenware, household food processing appliances, food production and processing machinery, etc.

2、 Inspection items of food contact materials

● detection items of plastic food contact materials:

1. Residual toxic monomers, lysates and toxic substances produced by aging in plastics, including several typical plastic toxic monomers vinyl chloride, vinylidene chloride, caprolactam, styrene, bisphenol A and acrylonitrile;

2. Various toxic additives added in the manufacturing process of plastic products, such as plasticizer phthalates;

3. Microbial and micro dust contamination on the surface of plastic containers;

4. Adhesive and solvent residues used in composite packaging bags, printing ink, etc.

● detection items of metal food contact materials:

Heavy metal dissolution test (4% acetic acid), lead (PB), cadmium (CD), chromium (CR), nickel (Ni), arsenic (as), antimony (sb), zinc (Zn)

● detection items of rubber food contact materials:

Benzidine, naphthylamine, m-toluidine diamine, Chloroaniline, phenylnaphthylamine, acrylonitrile, chloroprene, etc.

● inspection items of glass food contact materials:

Heavy metal dissolution test (4% acetic acid), lead (PB), cadmium (CD), chromium (CR), nickel (Ni), arsenic (as), antimony (sb), zinc (Zn)

● detection items of bamboo and wood food contact materials:

Pentachlorophenol (PCP), formaldehyde dissolution, total migration of organic coating, arsenic content, lead content, sulfur dioxide content, o-phenylphenol, thiabendazole, biphenyl and imazole content, etc.

● detection items of paper food contact materials

Lead (calculated by Pb), arsenic (calculated by as), fluorescent substances, decolorization test, coliform group, pathogenic bacteria (Shigella, Salmonella, Staphylococcus aureus, hemolytic streptococcus).

3、 Inspection and certification category of food contact materials

1. Since April 19, 2017, the mandatory requirements for the detection of food contact materials in China, GB 4806-2016 series standards, have been officially implemented. The specific material detection requirements are clearly specified in the standards, as follows:

a. GB 4806.2-2015 national food safety standard pacifier; GB 4806.3-2016 national food safety standard enamel products;

b. GB 4806.4-2016 national food safety standard ceramic products; GB 4806.5-2016 national food safety standard glass products; GB 4806.6-2016 national food safety standard plastic resin for food contact;

c. GB 4806.7-2016 national food safety standard plastic materials and products for food contact;

d. GB 4806.8-2016 national food safety standard paper and paperboard materials and products for food contact;

e. GB 4806.9-2016 national food safety standard metal materials and products for food contact;

f. GB 4806.10-2016 national standard for food safety coatings and coatings for food contact;

g. GB 4806.11-2016 national food safety standard rubber materials and products for food contact.

Basically, we are involved in common materials in food contact. Of course, it will be written that composite materials or degradable materials are not added to the standards. These series of standards will be formulated step by step.

2. European Union German food contact materials testing lfgb

The EC / 1935 / 004 framework regulation promulgated by the EU is the leading regulation on various food contact materials, and EU member states have the right to supervise the framework regulation. However, due to the lack of applicable material guidelines for the previous specific measures for 17 materials, according to Article 6 of EC / 1935 / 2004, when the specific measures for various materials and products have not been formulated, it is allowed to maintain and adopt the relevant provisions of Member States. Therefore, when exporting products to the EU, we should not only consider EC / 1935 / 2004, but also consider the relevant regulations of specific exporting countries. For example, in Germany and France, in addition to strictly following the EU directive 1935 / 2004, there are also local food level regulations that must be followed, such as lfgb (LMBG) in Germany, French dgccrf2004-64 in France, UK Si 898:2005 in the Commonwealth, Law No. 283 of 30 / 04 / 1962 in Gazzetta uficiale G.U and local decree 21 / 03 / 1973 (d.m.21 / 03 / 73).

In September 2005, the new German food and diet law lfgb replaced LMBG for food and daily necessities. It is also known as the law on the administration of food, tobacco products, cosmetics and other daily necessities. It is an important basic legal document for food hygiene management in Germany and the guideline and core for the formulation of other special food hygiene laws and regulations. Daily necessities in contact with food can be certified as "products without chemical toxic substances" by the lfgb test report issued by the authorized organization and can be sold in the German market.

Lfgb flag

The difference between lfgb and other food grade tests is that section 30 & 31 is required

§ 30 lfgb prohibits the sale of daily necessities containing toxic components that are harmful to human health

§ 31 lfgb prohibits substances that can migrate into food or affect the taste of food, thereby endangering human health

Lfgb test requirements are stricter than those of other countries, so lfgb test reports are also recognized in other countries. Generally, articles 30 and 31 of lfgb German food and daily necessities law include the following test items:

1. Preliminary inspection of samples and materials

2. Sensory evaluation of odor and taste transfer

3. Plastic samples: Test of transferable components and test of precipitable heavy metals

4. Test of metal composition and precipitable heavy metals

5. Silicone: Test for transferable or volatile organic compounds

6. Special materials: chemical hazards shall be inspected according to the German chemical law

Lfgb test items are closely related to test materials, such as paper products, wood products, polyethylene plastic (PE), polystyrene plastic (PS), polypropylene plastic (PP), polyamide plastic (PA), polyethylene terephthalate (PET), polycarbonate (PC), rubber, silicone rubber, metal, alloy and electroplating products, stainless steel tableware and ceramics, For glass products, different materials have different test items.

3. Inspection of food contact materials in the United States

I. basic understanding

All over the United States and all States have strict management and monitoring systems covering the field of food production, packaging and distribution to ensure the safety and hygiene of food contact materials and products. It is considered to be a safe food and packaged food supplier in the world. The U.S. Food and Drug Administration (FDA) plays a key role in this process. Its provisions on food contact safety regulations are very specific and complex. For materials and products in contact with food, FDA believes that food packaging materials belong to the scope of food additive management. FDA's definition of food additives includes all substances that become food ingredients or affect the properties of food through direct or indirect addition or contact with food. Substances that migrate into food due to packaging, storage or other processing processes are indirect additives.

FDA certification mark

Parts 174, 175, 176, 177, 178 of 21 U.S.C., food, drugs, and cosmetics (21.cfr. Part; 174.175.176.177.178) has detailed provisions on food additives.

Us food grade: U.S. FDA CFR 21 part 175-189 & FDA CpG 7117.05, 06, 07

► 21 CFR = food and drugs

► 21 CFR 175 = adhesives and coating

► 21 CFR 176 = paper and paperboard

► 21 CFR 177 = polymers (plastics and fabric)

► 21 CFR 181.32 = acrylonitrile copolymer (a < 30%) (acrylonitrile monomer < 30%)
