Abstract
A laminated tape includes: an adhesive material layer; a first polyolefin layer provided on one side of the adhesive material layer; and a second polyolefin layer provided on the other side of the adhesive material layer. The laminated tape is sandwiched between opposing base films of a packaging body to be welded. The polyolefin used for the first polyolefin layer and the second polyolefin layer is of the same type. The thickness of the respective layers of the laminated tape is preferably defined so that the thickness of the first polyolefin layer and the adhesive material layer is 30 μm or more and the thickness of the second polyolefin layer is less than 30 μm.
