Abstract
A dielectric welding film capable of tightly welding adherends of a polyolefin resin or the like within a relatively short time through dielectric heating, and a bonding method using the dielectric welding film are provided. The dielectric welding film is configured to bond a plurality of adherends of the same material or different materials through dielectric heating, the dielectric welding film containing (A) a polyolefin resin and (B) a dielectric filler whose mean particle size measured in accordance with JIS Z 8819-2 (2001) is in a range from 1 to 30 μm, a thickness of the dielectric welding film ranging from 10 to 2,000 μm. The method uses the dielectric welding film.

A dielectric welding film configured to bond a plurality of adherends of the same material or different materials though dielectric heating, the dielectric welding film comprising:
- (A) a polyolefin resin;
- and
- (B) a dielectric filler whose mean particle size measured in accordance with JIS Z 8819-2 (2001) is in a range from 2 to 50 μm, wherein
- the dielectric filler is zinc oxide, anatase-type titanium oxide or barium titanate, and
- a thickness of the dielectric welding film is in a range from 100 to 1000 μm.
(canceled)
A bonding method using a dielectric welding film configured to bond a plurality of adherends of the same material or different materials through dielectric heating, the dielectric welding film comprising (A) a polyolefin resin and (B) a dielectric filler whose mean particle size measured in accordance with JIS Z 8819-2 (2001) is in a range from 2 to 25 μm, the dielectric filler being zinc oxide, anatase-type titanium oxide or barium titanate, a thickness of the dielectric welding film ranging from 100 to 1000 μm, the method comprising:
- (1) holding the dielectric welding film between the plurality of adherends of the same material or different materials;
- and
- (2) applying the dielectric heating on the dielectric welding film held between the plurality of adherends with a dielectric heater at a frequency ranging from 1 to 100 MHz.
