Eddy Current in the foil used for sealing on the containers like pillboxes and beverage bottles

[NFC_Engineer]

Manufacturers would like to place NXP's NFC tags on metal foils that are sealed by the Induction heating equipment from vendors like Enercon Industries (https://www.enerconind.com/index.aspx).   This equipment generates a strong time-varying magnetic field that generates eddy currents on the foil located inside the container and placed near its rim. Have anyone measured the strength of the field? I am finding out that HF RFID-NFC tags degrade in performance (even stop performing) when the voltage induced in the antenna coil during induction heating may exceed the safe working voltage limit of the tag's chip. 

Have any of you observed this? any solution?
