Thermoplastic bag and bag pack

In a bag pack comprised of a plurality of stacked bags of thermoplastic material, each bag having opposite sides, bottom, front wall, back wall, open mouth and handles extending upwardly from said front and back walls on the opposite sides to define said mouth therebetween, the handles defining a pair of handle stacks in the bag pack with each handle of each stack having an aperture aligned with an aperture in each other handle of the stack for removably mounting said bag pack on a bag loading rack, the improvement wherein:

• each of said apertures is defined by a S-shaped slit with the opposite ends of the slit terminating immediately adjacent an intermediate section of the slit;
• each of said slits defines a two-part inner slit material bounded by said slit and outer slit material surrounding said slit;
• the two-part inner slit material of each handle is comprised of separate layers of material, the inner slit material of each layer being integrally and flexibly connected to said outer slit material of the same layer at two separate locations;
• the inner slit material of each handle stack is positioned for loose interengagement with the slit material of adjacent handles for holding said handles together in said handle stack with said apertures thereof aligned;
• and
• the interengagement of said slit materials provides the sole means of holding said handles together in said handle stacks.

In a bag of thermoplastic material having opposite sides, bottom, front wall, back wall, open mouth and handles extending upwardly from said front and back walls on the opposite sides of the bag to define said mouth therebetween, said mouth being further defined by an upper edge of the front and back walls extending between said handles;

• the improvement wherein:
• said front and back walls each include a tab section located between said handles and extending upwardly from the upper edge of each of said front and back walls in overlying relation with respect to each other, each of said tab sections having an outer edge connected to the upper edge of the respective front and back walls;
• a mounting slit in each of the front and back walls of the bag at the location of said tab sections;
• each of said slits having opposite ends spaced from one of said outer edges to leave bridging regions therebetween, said bridging region at one end of said slits defining a permanent connection for each tab section to the respective wall on which each tab section is included, the bridging region at the other end of the slits defining a tear away zone for permitting removal of the entire bag from a bag loading rack when the bag is mounted thereon with rack structure extending through said mounting slit.

• a mounting slit in each of the front and back walls of the bag at the location of said tab sections;
• each of said slits having opposite ends spaced from one of said outer edges to leave bridging regions therebetween, said bridging region, at least at one end of said slits, defining a permanent connection for each tab section, the respective wall on which each tab section is included, for permitting removal of the entire bag from a bag loading rack when the bag is mounted thereon with rack structure extending through said mounting slit;
• said slits defining a line of demarcation between said tab section and said front and back walls;
• said slits being substantially straight and located in linear alignment with said upper edges of the front and back walls of the bag extending between the tab sections and said handles to define part of said upper edges;
• the spacing of the slits with the upper edges of said front and back walls being greater at one end of the slits than at the other, with the bridging region at the one end defining said permanent connection.
