<p>A tearing strip of the delaminating type intended for attachment to opposite insides of a package. The strip has such a layer structure that, relative the inside of the package, it has a melted-together seal while internally the strip has layers which are not fully melted together. The strip comprises a central, strong layer (21) and a first (22, 23) and second (24, 25) layer arrangement. The first layer arrangement (22, 23) has a well reproducable, high seal strength relative the central layer. However, the second layer arrangement (24, 25) is "peelable" relative the first layer arrangements (22, 23) or more likely internally between two layers (25, 24). In contrary the second layer arrangement has a well reproducable, high sealing strength relative the inside (26, 27) of the package.</p> |
