A method of package formation and filling, comprising:
- providing a package having a first panel portion and a second panel portion, at least the first panel portion and the second panel portion sealed along first and second side seals and defining an interior package cavity adapted to hold material contents;
- providing a fill slit opening defined in a portion of the first panel portion;
- providing a unitary fill strip having a first longitudinal edge portion, a longitudinal free end portion, and first and second ends transverse to at least the first longitudinal edge portion, the first longitudinal edge portion sealed to an interior surface of the first panel proximate a first side of the slit opening, the first and second ends sealed to the first and second side seals such that a portion of the unitary fill strip intermediate the first and second side seals does not seal to an interior surface of the second panel portion;
- filling at least a portion of the interior package cavity with material contents via the fill slit opening, past the free end portion;
- and
- sealing the free end portion to the interior surface of the first panel proximate a second side of the fill slit opening within the interior package cavity, after filing the interior package cavity with the material contents.
