Beschreibung
Zusammenfassung:	A packaging system has a peelable seal section which includes a first sealing layer and a second sealing layer such that the first sealing layer contacts the second sealing layer to form a peelable seal. The first sealing layer includes thermoplastic polymer or a blend of thermoplastic polymers, an organoclay dispersed within the thermoplastic polymer, a first additional inorganic additive component dispersed within the thermoplastic polymer and a second additional inorganic additive component dispersed within the thermoplastic polymer. The first additional additive component and/or the second additional additive component is selected from the group consisting of calcium carbonate, hydrated magnesium silicate (talc), magnesium carbonate, titanium oxide, magnesium oxide, magnesium sulfate, barium sulfate, barium aluminates, barium borate, barium silicate and combinations thereof.
