1. Definition of food grade silicone
Food Grade Silicone is a polymer material that has undergone strict testing and certification. Compared with ordinary industrial silicone, it is non-toxic, odorless, high temperature resistant, and corrosion resistant, and can be in direct contact with food and the human body.
Common applications include:
Pacifier heads, nasal aspirators, and baby bottle accessories
Food containers, straws, silicone seals
Medical and maternal and infant products (such as breast pumps, respirators)
2. Why choose food-grade silicone?
Health and safety guarantee: does not release harmful substances, does not contain BPA, plasticizers or heavy metals.
High and low temperature resistance: -40°C ~ +230°C, it can still maintain stable elasticity and is not easily deformed.
Anti-aging and weather resistance: not easy to yellow and brittle, and has a long service life.
No odor: ensures no contamination of food or drinking water.
Easy to clean and disinfect: can withstand steam sterilization, boiling, ultraviolet sterilization and other treatments.
3. Common international certification and safety standards
Certification/Standards | Scope of application | Content and requirements | Applicable products |
FDA CFR 21 177.2600 (USA) | food contact materials | Standardize silicone not to release harmful substances in the food environment | Pacifier head, silicone straw, sealing ring |
LFGB (German food grade certification) | EU food contact | The testing standards are more stringent than the FDA, requiring no odor and no release of harmful substances. | Kitchen supplies, baby products |
EU 1935/2004 (European Union) | food contact materials | Specifies that materials that come into contact with food will not affect food safety and taste | Food containers, seals |
RoHS (European Union Environmental Directive) | Electronics/Components | Restrict 10 hazardous substances such as lead, cadmium, and mercury | Industrial and food equipment parts |
REACH (European Union Chemical Regulations) | Chemical substance control | Ensure materials do not contain Substances of Very High Concern (SVHC) | Comprehensive application |
GB 4806 (China food contact materials) | food grade standards | National standards for silicone and plastic food contact materials | Food utensils, baby pacifiers |
4. Food grade silicone vs. general silicone
Food-grade silicone: It must pass the above-mentioned FDA, LFGB, RoHS and other tests, has no peculiar smell, and can be safely contacted with food and human body.
Industrial grade silicone: Mainly used for machinery, shockproof, and waterproofing. It may not be food contact safe and may contain volatile components or fillers.
Therefore, if your product is used in infants, food, or medical fields, you must choose food-grade silicone. Otherwise, it may affect consumer health and cause compliance risks for export sales.
5. Conclusion
The correct selection of materials with international certification can not only ensure product safety, but also an important guarantee for enterprises to enter the international market.
