Abstract
Official abstract text for this publication.
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, and an additional inorganic additive component, such as calcium carbonate, dispersed within the thermoplastic polymer. The peelable seal has achieved synergistic effect and offers high thermal conductivity, great caulkability and is consistent over a broad range of sealing temperatures without loss of desired peelable seal functionality as the seals age.
