A tear strip opening device disposed on a sealing portion of a container which comprises a non-tearable plastic strip or ridge positioned on the inside thereof along a perforated punch line and a non-tearable material e.g. a small plastic band disposed outside of the sealing portion thereof and on the opposite side of the non-tearable strip. Thus, the plastic strip or ridge disposed between the non-tearable band and a glued portion disposed on the inside of the sealing portion thereof is in substantially parallel relationship to the plastic band for use in easily and readily opening the container.
