PROBLEM TO BE SOLVED: To obtain a polyolefinic bonding sheet capable of forming a heat- resistant sleeve by a solvent adhesive seal method by providing a chlorinated polyolefinic resin layer having specific thickness on the respective superposing surfaces of both end parts to be bonded. SOLUTION: In a polyolefinic bonding sheet 4 mutually superposing and bonding both end parts of a polyolefinic resin sheet to form a sleeve, a chlorinated polyolefinic resin layer 3 having a thickness of 5-20μm is provided on the surfaces of the respective superposing parts 2a, 2b of both end parts to be bonded. The chlorinated polyolefinic resin layer 3 is pref. a polyolefinic resin with a chlorination ratio of 30-80wt.%. As a method for providing the chlorinated polyolefinic resin layer 3 to both end superposing parts 2a, 2b of the polyolefinic resin sheet, for example, a method for printing a resin compsn. based on a chlorinated polyolefinic resin dissolved in a solvent such as toluene is pref. |
