Abstract
Bag making material comprises a plastic film carrying a reclosable fastener or zipper male profile and with one or more alignment ribs in spaced parallel relation to the profile. Reinforcing ridge or ridges provide stabilizing beam effect in respect to the profile and/or the alignment rib or ribs on the film along the back of the profile and/or alignment rib base or bases.

Bag making material including film and a male zipper profile, comprising:
- an extruded plastic film;
- an elongated extruded plastic male zipper profile having a base attached to said film;
- an extruded plastic alignment rib having a base attached to said film in adjacent spaced parallel relation to said male profile;
- and
- a stabilizing ridge on said film along the back of said male profile base and extending at least partially onto the back of said rib base and having a stabilizing beam effect with respect to the relation of said male profile and alignment rib.
Bag making material including film and a male zipper profile, comprising:
- an extruded plastic film;
- an elongated extruded plastic male zipper profile having a base attached to said film;
- an extruded plastic alignment rib on said film in adjacent spaced parallel relation to said male profile and having a base attached to said film;
- and
- a stabilizing ridge on said film along the back of said alignment rib base and having a stabilizing beam effect with respect to the relation of said alignment rib to said male profile.
Bag making material including film and a male zipper profile, comprising:
- an extruded plastic film;
