封止のための方法及び装置

Document Type and Number:

Japanese Patent JP4568761

Kind Code:

B2

Abstract:

A method for sealing a first packaging material laminate, comprised of at least one layer of magnetizable particles and a sealable layer, to a second packaging laminate involves facing the sealable layer towards the second laminate, providing an alternating magnetic field to the laminates in a sealing zone, thereby generating magnetic hysteresis losses in the laminate having the magnetizable particles, which losses create heat substantially melting the sealable layer in the sealing zone, and applying a sealing pressure to the first and second laminate to cause the first and second laminate to be pressed together in the sealing zone, thereby sealing the laminates to each other.
