ABSTRACT:
A composite strip for producing a sterile package comprises two superposed individual strips, the inner surfaces of which are sterile, and at least one of which comprises a thermoplastic material. The thermoplastic material is such that after the separation of the two individual strips, the individual strip comprising thermoplastic material can be sealed to a part of itself or to the other strip by welding or glueing with the application of heat and pressure. A first part of one individual strip and another part of the same strip or of the other individual strip are joined at their edges in a sealed manner to form a hollow and sealed packing.
