Short Answer
Yes, but only if you use a specifically formulated and certified food-grade ABS.
Standard general-purpose ABS is not inherently safe for food contact. Without proper certification, it may contain additives, colorants, or residual monomers that do not meet food safety standards, which could migrate into food and exceed legal safety thresholds. To ensure food safety, you must use ABS that complies with US FDA or EU food contact regulations.
What are the Potential Risks of ABS in Food Contact?
ABS is polymerized from three monomers: acrylonitrile, butadiene, and styrene. The primary risk regarding safety is that these low-molecular-weight substances might migrate from the plastic into food.
| Monomer | Health Risk | Regulatory Control |
| Acrylonitrile | Classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen (carcinogenic to humans). | FDA 21 CFR 177.1020 stipulates that the migration limit must not exceed 0.0015 mg/square inch. |
| Butadiene | Classified by IARC as a Group 1 carcinogen (carcinogenic to humans) and by the US National Toxicology Program as a known human carcinogen. | Residual levels in the finished product are extremely low, and the production process is strictly controlled. |
| Styrene | Some studies suggest potential migration, but it is considered safe at approved usage levels. | EU Regulation 10/2011 sets a Specific Migration Limit (SML) for styrene. |
Two points that need clarification:
- ABS does not contain Bisphenol A (BPA). This is a common misconception.
- ABS does not contain phthalates (plasticizers). ABS itself is a rigid plastic and does not require the addition of plasticizers.
However, non-food-grade ABS may contain:
- Uncontrolled additives or recycled materials of unknown origin
- Heavy metal residues from certain pigments
- Impurities introduced by poor recycling processes
Which Regulatory Standards Must Food-Grade ABS Comply With?
To be deemed safe for food contact, ABS must pass rigorous migration testing by the following authoritative bodies:
- US FDA
- 21 CFR 177.1020: Regulates that acrylonitrile/butadiene/styrene copolymers can be used in food contact articles, and the acrylonitrile monomer migration must not exceed 0.0015 mg/square inch.
- 21 CFR 181.32: Permits the use of ABS in food-handling conduits and reusable food contact articles.
- European Union
- Framework Regulation (EC) No 1935/2004: Requires that all food contact materials must not transfer their constituents to food in quantities that could endanger human health.
- Plastics Regulation (EU) No 10/2011: Sets an Overall Migration Limit (OML) of 10 mg/dm² (or 60 mg/kg of food simulant) and establishes specific migration limits for acrylonitrile, butadiene, and styrene.
- Other Certifications: China’s GB 4806, Japan’s Food Sanitation Act, etc.
How to Properly Identify Food-Grade ABS?
When sourcing ABS for food contact applications, you must request the following documents from your supplier:
- Certificate of Analysis (COA), clearly showing compliance with FDA or EU standards.
- Food Contact Declaration, specifying that the product meets applicable regulations.
- Third-Party Laboratory Migration Test Reports (recommended).
Situations to be wary of:
- The supplier cannot provide any food contact certification.
- The ABS is labeled as “general-purpose grade” without any regulatory statements.
- The price is significantly lower than certified food-grade ABS (indicating potential use of recycled material or substandard products).
Common Applications of Food-Grade ABS (Upon Certification)
- Refrigerator liners and ice maker components
- Small kitchen appliance housings (coffee makers, blenders, food processors)
- Food storage containers and trays
- Water dispenser components
- Food processing equipment components
Can Recycled Food-Grade ABS Still Safely Contact Food?
No. Once ABS has been recycled, it generally cannot be reused for food contact applications. During the recycling process, the material can become contaminated, mixed with non-food-grade plastics, or undergo thermal degradation. Recycled ABS is typically downgraded for use in non-food contact industrial fields (such as automotive parts, electronic enclosures, and construction materials).
