Plastic straws are subject to the GB4806 testing project in China. As food contact materials, plastic straws sold in the Chinese market must comply with the requirements of GB 4806.7-2016 "National Food Safety Standard for Plastic Materials and Products in Contact with Food". The following are the main testing items:
1、 General testing items
|Serial number | Testing item | Limit requirement | Description
|1 | Sensory requirements | No odor, strange smell, or dirt; The soaking solution is free of turbidity, sedimentation, and discoloration | direct observation and soaking test
|2 | Total migration amount | ≤ 10 mg/dm ² (or ≤ 60 mg/kg) | Mass of dissolved substances in simulated food contact
|3 | Potassium permanganate consumption | ≤ 10 mg/kg | Reflects the degree of organic matter dissolution
|4 | Heavy metals (calculated as Pb) | ≤ 1 mg/kg | Lead element content limit
|5 | Discoloration test | Negative | Evaluate the stability of coloring agents
2、 Specific migration detection project
According to the different materials of plastic straws, additional testing is required for specific migration substances:
1. Polypropylene (PP) straw: evaporation residue, n-hexane extract, etc
2. Polyethylene (PE) straws: water extract, 65% ethanol extract, etc
3. Polylactic acid (PLA) biodegradable straw: meets the relevant standards for biodegradable materials
4. Plastics containing additives: Specific migration amounts of specific additives need to be tested
3、 Supplementary explanation
Scope of application: Plastic straws for food contact mainly produced from polypropylene, polyethylene, polylactic acid, etc
Testing cycle: usually 5-7 working days
Sample requirement: It is recommended to provide 3-5 sets of actual sales products
Identification requirements: The product must be labeled with "for food contact", material information, and production date, etc
