Closure arrangement having a breakaway seal

A closure arrangement for a polymeric bag having first and second opposing films, comprising:

• a first base strip having an inner and outer surface, said outer surface of said first base strip being adapted for attachment to the first film;
• a second base strip opposing said first base strip, said second base strip having an inner and outer surface, said outer surface of said second base strip being adapted for attachment to the second film;
• a post generally perpendicular to said first base strip;
• and
• an L-shaped breakaway member having first and second legs, said first leg being generally parallel to and substantially co-planar with said first base strip, said first leg having opposing inner and outer surfaces and opposing upper and lower sides extending between said inner and outer surfaces, said inner surface of said first leg being adapted for attachment to the second film, said second leg being generally perpendicular to said first leg and joined to said first leg in close proximity to one of said upper and lower sides, said post extending inwardly from said inner surface of said first base strip adjacent to said second leg, said second leg and said one of said upper and lower sides of said first leg being detachably connected to said respective post and said first base strip to form a breakaway seal.

A method of manufacturing a closure arrangement for a polymeric bag having first and second opposing films, said method comprising the steps of:

• forming a first base strip having an inner and outer surface;
• forming a breakaway member having a first leg generally parallel to and substantially co-planar with said first base strip, said first leg having opposing inner and outer surfaces and opposing upper and lower sides extending between said inner and outer surfaces;
• detachably connecting one of said upper and lower sides of said first leg to said first base strip to form a breakaway seal;
• attaching said inner surface of said first leg to the second film;
• and
• attaching said outer surface of said first base strip to the first film.
