摘要：
Packaging produced from a thermoplastic film of which the ends are placed so that they abut, said film being composed of several layers, including at least a first weldable layer and a second layer of which the butt-welding is only partial or non-existent, and at least one thin strip covering said ends and being directly attached to one of the faces of the second layer, the difference in the melting point between the first layer and the other layer or layers being greater than 20° C.
