Abstract
An easy open bag and method for making the same. A film is fed into a jaw assembly comprising a first seal jaw comprising a blade gap and a second seal jaw comprising a removable insert. The removable insert comprises a blade pin. When the first and second seal jaws are mated, a notch is formed. The film also comprises a score line in the outer layer. Upon tearing the notch the tear propagates along the score line. Thus, the package can be easily opened by initiating a tear at a tear notch.
