PEELABLE SEALING STRUCTURE (EMBODIMENTS) AND PACKAGING SYSTEM

摘要

A peelable sealing structure includes a first sealing layer having the first sealing surface and a second sealing layer having the second sealing surface. The first sealing surface is brought in contact with the second sealing surface determining a sealing seam so that one or both layers from the first and second layers will have one of few representatives selected from the folds and over-bending included therein. At that at least one layer chosen from the first and second sealing layers comprises thermoplastic polymer and organic clay dispersed in, at least, portion of thermoplastic polymer. Seal temperature range varies from sealing initiation temperature to that, at least 100F higher than the former. Said sealing initiation temperature varies from 170F to 350F. Organic clay comprises plates separated by at least 20 Angstroem units. Sealing surface features mean roughness of 1500-5000 Angstroem units.
