  • Publication number: 20130130007
    Abstract: A method for producing a terminal bonding tape includes providing a multi-layer film having a linear polyethylene surface layer, a linear polyethylene intermediate layer and an acid-modified polyethylene surface layer, and irradiating the multi-layer film with a radiation beam from the side of the linear polyethylene surface layer to cross-link the linear polyethylene intermediate layer. The linear polyethylene surface layer is made of a high-fluidity linear low-density polyethylene having an MFR of 5 to 30 g/10 min or a linear polyethylene with a density of 918 to 940 kg/m3, while the linear polyethylene intermediate layer is made of a low-fluidity linear low-density polyethylene having an MFR of 0.7 to 6 g/10 min or a linear polyethylene with a density of 865 to 917 kg/m3. The radiation cross-linked intermediate layer shows significant reduction in fluidity with the fluidity of the both surface layers being maintained in an acceptable level.
