    • PURPOSE: To make a three- or more-ply composite cylindrical wrapper of a resin film easily openable. CONSTITUTION: The cylindrical wrapper 1 of a composite resin film, cylindrically formed, is obtained by circularly bending a base material film 2, superposing the circularly bent both ends over each other and thermally sealing 7 the film with an unheat-sealed part 8 left as it is on the end side of the film positioned on the upper side of the superposition, for the purpose of wrapping the contents. In this wrapper 1, the base material film 2 is a three- or more-ply composite resin film, and then the release strength between an outer layer film 5 and an intermediate layer film 3 is set to be lower than the release strength between an inner layer film 4 and the intermediate layer film 3. Thus when the wrapper 1 is opened, the outer layer film 5 easily breaks from the intermediate layer film 3 at the heat-sealed part 7 and further, is released 13. Consequently, the wrapper 1 can be easily opened.
    • 目的:制作一个三层或更多层复合圆柱形包装的树脂薄膜容易打开。 构成:圆柱形形成的复合树脂膜的圆筒状包装物1是通过使基材薄膜2圆形弯曲而形成的,将圆形弯曲的两端重叠在一起,将未热封部8的膜热封7,作为 为了包装内容物,位于叠置上侧的胶片的末端。 在该包装物1中,基材膜2为三层以上的复合树脂膜,外层膜5与中间层膜3之间的剥离强度设定为低于 内层膜4和中间层膜3.因此,当包装物1打开时,外层膜5在热封部分7处容易从中间层膜3断裂,并进一步被释放13.因此,包装物 1可以轻松打开。
