Title: Sealing method
Inventor: HILMERSSON ANDERS
IPC: H05B6/10
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To reduce a skew of a seal which is likely to occur at a side rim of a packaging material by concentrating a magnetic field due to high frequency current using a high permeance local insert at the side rim of the packaging material, in a method for high-frequency heating and pressing packaging materials between a sealing jaw and a holding jaw to have them sealed to each other. SOLUTION: A sealer having a sealing jaw 12 and a holding jaw 14 placed oppositely to the jaw 12 is used to hold packaging materials 13 with a metallic foil coated by a thermoplastic material between the sealing jaw 12 and the holding jaw 14 to press them while being heated with high frequency current applied. Thus the materials 13 are sealed to each other by two lines. Further a local insert 11 having higher permeance than that of a core 10 of the sealing jaw 12 is placed in the vicinity of each side rim of the packaging material 13 to concentrate, on this part, a magnetic field caused by the high frequency current. This constitution reduces a skew of a seal which is likely to occur at a side rim of the packaging material 13.
