    摘要: The present invention is drawn to a strip tape which does not undergo lowering of bonding force and which does not cause pollution of the natural environment, working environment, etc. The strip tape includes a center layer containing a polar resin, and at least one polyolefin layer laminated, via a bonding layer, on each face of the center layer. The bonding layer contains an ethylene-methacrylic acid-alkyl acrylate random copolymer. Since the strip tape includes a center layer and at least one polyolefin layer, the interlayer bonding force of the strip tape is high, the bonding strength between the center layer and the polyolefin layer can be increased, and the waterproofing property of the strip tape can be enhanced. Even when a packaging container including the strip tape is heated or cooled sharply during use, the interlayer bonding force of the strip tape is not lowered.

    摘要: A process for producing a barrier packaging material reduces the number of processes, simplifies each of the processes per se, is relatively thin even though a multilayer, reduces the number of adhesive layers, and is advantageous in cost and environment. The process involves providing a 20 μm to 45 μm thick biaxially oriented film having ethylene-vinyl alcohol copolymer layers, polyamide layers directly bonded to both surfaces of the ethylene-vinyl alcohol copolymer layers and heat-adhesive polyethylene layers laminated via adherent resin layers at each external surface of the polyamide layers, subjecting to corona discharge treatment on the surfaces to be joined by poly(ethylene terephthalate) films of 5 μm to 15 μm thickness and the biaxially oriented film, and after the above-described treatment, performing thermocompression bonding of the treated surface to be joined by the poly(ethylene terephthalate) films and the biaxially oriented film, by means of nip rolls.
