Short answer: PA (polyamide) plastic can be used for food contact when it is a compliant resin: the US has 21 CFR 177.1500 for nylon 6 and nylon 66, and the EU has Regulation 10/2011. PA is not made from bisphenol A (BPA). But “absolutely safe” is not correct: BfR (Germany) notes that PA oligomers migrate significantly into food hotter than 70 °C, and recycled PA has no clear legal route into food use.
Many articles online claim PA is “absolutely safe, withstands 260 °C and releases nothing”. All three claims need correcting: 260 °C is the melting point of PA66, not a safe cooking temperature, and migration depends on the resin, the temperature and the contact time. This article relies on FDA and EU rules and BfR advice to separate what has a basis from what does not.
BPA and the substances that can really migrate from PA
PA does not use bisphenol A as a raw material. The list of substances BfR checks for PA kitchen utensils includes caprolactam (PA6), hexamethylenediamine and adipic acid (PA66), and no bisphenol A; this matches the structure of PA described by Asahi Kasei (a repeating chain of amide groups formed from an amine and an acid). So “PA contains no BPA” has a basis, but it is a statement about raw materials and does not mean “nothing migrates”.
The substances of concern are residual monomers and oligomers. EU 10/2011 sets specific migration limits: caprolactam 15 mg/kg of food, hexamethylenediamine 2.4 mg/kg, adipic acid 60 mg/kg (figures as quoted by BfR). The US rule 21 CFR 177.1500 sets a maximum residual caprolactam of 0.7% by weight for nylon 6/66 type 4.1 and separately regulates the amount extracted in water and solvents. 21 CFR 177.1500 is a rule on resin composition, not an “FDA certificate” for the finished product, as many articles call it.
| Regulation | Issued by | What it covers for PA |
|---|---|---|
| 21 CFR 177.1500 | FDA (US) | Permitted nylon types, extraction limits, residual caprolactam |
| Regulation (EU) 10/2011 | EU | Specific migration limits for each monomer, checked under the conditions of use |
| BfR advisory (Germany) | BfR | Reduce the time PA kitchen utensils are in contact with hot food |
Temperature: 260 °C is not a safe cooking level
PA6 melts at 220 °C and PA66 at 260 °C (BASF). That is the temperature at which the material turns liquid, not a temperature for use. Under a 1.8 MPa load, PA6 deforms at about 60 °C and PA66 at 75 °C (unreinforced grades). On food safety, BfR has a clear advisory: PA oligomers migrate into food significantly when hot above 70 °C, so keep PA ladles and spatulas in contact with hot food as briefly as possible.
Three comparisons found in many articles (PET “deforms above 70 °C”, PVC “gives off toxic gas when burned”, PA “stable at 100 to 120 °C without releasing free radicals”) have no measured source that could be found, so they are not used. The sourced parts are the melting points, the HDT and the 70 °C advisory above.
Virgin and recycled PA
Virgin resin has a clear material record, so it is the only sensible choice for food contact. Recycled resin is different: FDA reviews each case, naming three main concerns: contaminants from earlier use, input material not permitted for food, and additives that do not meet the rules. The EU rules under Regulation 2022/1616: recycled plastic in food contact may be placed on the market only when it uses a listed or authorised recycling technology and meets the requirements of 10/2011.
In practice, EFSA currently assesses mainly mechanical recycling technologies for post-consumer PET. No authorised PA recycling process for food contact was found, so for recycled PA a cautious conclusion is: do not use it for food unless the supplier can show a process authorisation. For castor wheels, machine parts and industrial mesh, recycled PA is still usable because there is no food contact.
Where PA is used, on a sound basis
Row 6.2 in the table of 21 CFR 177.1500 allows nylon 6 as food-contact film no thicker than 0.001 inch (about 25 micron), so nylon film inside multilayer packaging has a legal basis. Repeated-use utensils such as ladles and spatulas are covered by a similar rule but must follow the extraction limits above and BfR’s heat advice. In industry, PA is used for wheels, bushings and gears, where there is no food contact; that falls under the articles on PA6 and PA66 and outside the scope of food safety.

Frequently asked questions
Is PA plastic safe?
Yes, when it is a food-grade resin (21 CFR 177.1500, EU 10/2011) and used at the right temperature. Do not say “absolutely safe”: BfR notes that oligomers migrate significantly when hot above 70 °C.
Does PA plastic contain BPA?
No. PA is made from caprolactam, or from hexamethylenediamine with adipic acid; BPA is not on the list of PA monomers.
How much heat can PA plastic withstand?
It melts at 220 °C (PA6) and 260 °C (PA66), but under a 1.8 MPa load it holds only to 60 and 75 °C. For hot food, keep it under 70 °C according to BfR advice.
Can recycled PA be used for food?
It should not be. The EU requires a listed or authorised recycling technology (2022/1616) and FDA reviews each case; no authorised PA process was found.
Is 21 CFR 177.1500 an FDA certificate?
No. It is a rule on permitted nylons and extraction limits, not a certificate for the finished product.
Is it fine to use PA ladles and spatulas with a hot pan?
Limit long contact with hot food, and do not leave PA resting on a pan that is heating.
