Document Type and Number:
Japanese Patent JP6941653
Kind Code:
B2
Abstract:
To provide a bag body with a zipper tape which includes the zipper tape capable of being satisfactorily bonded by using energy ray.SOLUTION: An absorption layer 23 and a bonding layer 24 are stacked and formed on a surface of an opposite side to the side provided with a male part 212 or a female part 222, to a belt-shaped male side base part 211A integrally provided with a male portion 212 and a female side base part 221A integrally provided with a female part 222. The absorption layer 23 contains an absorber material absorbing laser light of 800 nm or more and 1200 nm or less in a wavelength absorption region. The bonding layer 24 contains a metallocene-based linear low density polyethylene being a low melting point resin having a melting point of 60°C or more and 120°C or less. When a zipper tape 20 is bonded to a base film 11, the absorption layer 23 is heated by irradiation of the laser light and the bonding layer 24 is melted. The molten bonding layer 24 is crimped to the base film 11 and bonded. The base film 11 can be bonded without causing heat deterioration.SELECTED DRAWING: Figure 2
