The present invention relates to unit dose packages for transdermal therapeutic systems or film- or sheet-type dosage forms in the form of a peel-open side-sealed bag, as well as to a method for producing such side-sealed bags that is low in material expenditure, said side-sealed bags comprising two packaging material elements which are arranged one upon the other and of which at least one consists of a tear-resistant packaging material which has a low tear propagation resistance. Said unit dose packages are characterised in that the two packaging material elements, which are joined to each other by a continuous sealed seam extending around the packaged good, thus forming a side-sealed bag, have a tab at one end of said side-sealed bag, which tab projects beyond the sealed margin, wherein said tabs are essentially half as wide as the side-sealed bag and, at the end thereof which faces away from the sealed margin, have a sealed region in which they are joined to each other, and wherein at least one of the packaging material elements has a structure for partial tearing of the packaging material in the region of the tab in which said tabs are not sealed to each other, said structure for partial tearing of the packaging material being without contact to the edge of the package. The invention also relates to methods for producing these unit dose packages which are particularly low in material consumption.

La présente invention concerne des emballages de dose individuelle pour des systèmes thérapeutiques transdermiques ou des formes galéniques pelliculaires sous la forme d'une poche à bord scellé amovible ainsi qu'un procédé économisant la matière pour sa fabrication. Ces emballages comprennent deux éléments de matériau d'emballage qui sont disposés de manière superposée et dont au moins un élément de matériau d'emballage est constitué d'un matériau d'emballage résistant à la déchirure qui présente une résistance à la propagation du déchirement moindre, qui se caractérisent en ce que les deux éléments de matériau d'emballage, qui sont reliés ensemble pour former une poche à bord scellé par un joint de scellement continu entourant le produit emballé, présentent à une extrémité de la poche à bord scellé une bride qui fait saillie du bord scellé. Les brides ont une largeur qui est essentiellement la moitié de celle de la poche et présentent à leur extrémité qui est opposée au bord scellé une zone de scellement où elles sont reliées entre elles, et au moins un des éléments de matériau d'emballage présente une structure pour déchirer le matériau d'emballage dans la zone des brides où les brides sont scellées ensemble, la structure pour déchirer le matériau d'emballage n'ayant pas de contact avec le bord de l'emballage.
