PEELABLE SEALING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an improved peelable packaging system which prevents leakage, provides airtight sealing, and can easily open.SOLUTION: A peelable sealing structure comprises a sealing layer 152 and one or more optional additional layers 154. The peelable sealing structure comprises a sealing surface that is formable into a peelable seal part when contacting with a sealing substrate at all temperature in a peelable seal temperature range. Moreover, the peelable sealing structure comprises a thermoplastic polymer and an additive dispersed within at least a portion of the thermoplastic polymer. The peelable sealing structure defines a sealing surface.
