Frangeros new packaging is dangerous

I ordered food today from them and they wrapped the chicken in a new wrapping. The wrapping is giving a chemical taste and not sure if it's poisonous. I have left the food in the wrapping and I tried calling the store but the store in cornubia lines are not been picked up or the Durban North branch. Did they even do a test on the new wrapping to see if it compatible to their producf
