ABSTRACT:
A bag having a tamper evident closure and methods of forming the same are provided. The bag has a tube body with a front wall and a back wall positioned between a first end and a second end. A back flap extension member connects to and extends outwardly from the second end of the back wall. A primer material is positioned on the back flap extension member and an adhesive material is placed on the back flap extension member that folds over to overlie and contact the primer material. The back flap extension member adheres to the front flap extension member and portions of the front wall to close the second end. When the back flap extension member liftingly separates from the front wall, at least one of the back flap extension member and the front wall tears indicating evidence of tampering.
