Tamper evident peelable seal

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

• a first base strip having inner and outer surfaces, said outer surface of said first base strip being attached to an inner surface of the first film;
• a second base strip having inner and outer surfaces, said second base strip being generally parallel to and opposing said first base strip, said outer surface of said second base strip being attached to an inner surface of the second film;
• a first peelable strip of a first color attached to said inner surface of said first base strip and disposed between said first and second base strips;
• and
• a second peelable strip of a second color attached to said inner surface of said second base strip and disposed between said first and second base strips, said second color being lighter than said first color, said second peelable strip being generally parallel to and opposing said first peelable strip, said first color of said first peelable strip being visible through said second peelable strip when said first and second peelable strips are heat sealed to each other to form a peelable seal, said second color of said second peelable strip substantially masking said first color of said first peelable strip when said peelable seal is broken.

A method of manufacturing a closure arrangement for a polymeric bag, comprising the steps of:

• forming a first panel having inner and outer surfaces;
• forming a second panel having inner and outer surfaces, said second panel being generally parallel to and opposing said first panel;
• forming a first peelable strip of a first color between said first and second panels, and attaching said first peelable strip to said inner surface of said first panel;
• forming a second peelable strip of a second color between said first and second panels, and attaching said second peelable strip to said inner surface of said second panel, said second color being lighter than said first color, said second peelable strip being generally parallel to and opposing said first peelable strip;
• and
• heat sealing said first and second peelable strips to each other to form a peelable seal such that said first color of said first peelable strip is visible through said second peelable strip, said second color of said second peelable strip substantially masking said first color of said first peelable strip when said peelable seal is broken.
