SEALING MATERIAL

摘要

The invention concerns a material comprising a support and a heat-sealing layer including a standard heat-sealing varnish, heat-sealable at heat-sealing temperature T included in a temperature range DELTA T, typically of 40 DEG C ranging between 170 DEG C and 210 DEG C, and peelable with a peeling force F varying by DELTA F on said temperature range. The invention is characterised in that said heat-sealing layer further comprises a peeling force stabiliser, of type and content selected so as to obtain a peeling force F' varying by DELTA F on said temperature range, with DELTA F'/ DELTA F not more than 0.5.
