There is no inner seal that you need to remove from the soymilk carton. However, the cap has a tamper-evident ring that is broken when the product is opened. The screw-top cap is designed to automatically cut the foil seal inside the carton when you first twist off the cap. You will see three plastic prongs on the inside of the cap and these prongs cut the foil seal on the carton. Before purchasing the product at store, please check that the tamper-evident ring has not been broken.
