Maybe it is less relevant for food, but other products (as clothes) which is now part of OPF, sometimes don’t have any product name on its packaging
Product barcode: 2141800550000
According to “Good Practices” in the OFF, brand name is not part of product name and should not be added. So “Decathlon” is not product name.
So for now I just wrote “[DOESN’T HAVE PRODUCT NAME ON ITS PACKAGING]” and added a commentary in folksonomy of this product page.
But I think we need to decide how to handle similar cases in future
