We are happy to confirm all our can liners are free from BPA.
Use of BPA in canned food products
When we use steel cans to package foods we need to protect the food from the can, and we need to protect the can from the food. We do this by coating the food contact surfaces of the can with a surface coating. In the past tin was used (hence the name "tin can") but nowadays all can liners are coatings made from film forming resins and epoxies.
Most of these coatings that are used in steel can liners worldwide contain Bisphenol A, aka BPA. This is a chemical that is added to plastics and coatings to change their behaviour. It has been shown that when (esp. acidic) food products are stored in cans using a coating that contains BPA, that BPA can migrate into the food product over time.
There is some concern over the impact of BPA consumption on both human health and the environment, which has led to banning its use in baby bottles and infant formula packaging. In 2017 BPA was added to the EU REACH registry as a substance of very high concern (SVHC).
Thai Gold coconut milk is not acidified and is naturally only marginally acidic. It is thus a low risk product in terms of liberation of BPA from the can liner. However we have been able to source can liners that are free from BPA and we feel that the additional cost is a good investment given the current lack of understanding of the impact of BPA. All Thai Gold products are thus packaged in cans with liners that are free from BPA.
