Definitions

• the present invention relates to pressure-sensitive laminated or substrate sections whose pressure-sensitive adhesive side is provided with a protective cover.
• the said laminate or substrate sections are Transdermal Therapeutic Systems (TTS), in particular therapeutic (drug-containing) patches.
• TTS Transdermal Therapeutic Systems
• pressure-sensitive adhesive laminate sections are known.
• the pressure-sensitive adhesive side i. the side which adheres to the patient's skin during application is covered with a protective film, a so-called release liner, in order to prevent the sections from sticking to one another or to the outer packaging.
• the protective film is provided with a mostly central section, which allows easy removal of the film in at least two sections and therefore serves as a removal aid.
• Such systems are e.g. described in DE 3344335 A1.
• the adhesive of the pressure-sensitive adhesive side of such a laminate section or TTS has a viscosity dependent on the viscosity at room temperature, referred to as cold flow. This can lead to the adhesive emerging from the cut edge during storage of the sections and thus resulting in extremely disadvantageous bonding of the sections to one another or to the outer packaging, usually a packaging material bag.
• the protective film on the pressure-sensitive adhesive layer is formed so that it consists of two film sections that overlap in the region of the cut edge.
• this measure does not prevent in all cases, in particular in the case of TTS products with formulations which tend strongly for adhesive leakage, from sticking TTS product to the packaging.
• the production of such products proves to be in need of improvement.
• the TTS laminate consisting of backing layer, matrix and intermediate covering, is contour-punched through the backing layer and matrix and after removal of the excess residual laminate The punched TTS are transferred individually with the help of the intermediate carrier / cover on a new protective film (Relase-Liner).
• This protective film has an overlap in order to prevent an adhesive leakage in the region of the cut edge.
• This method is susceptible to interference, since numerous materials must be moved simultaneously and precisely positioned.
• a further disadvantage is that the intermediate carrier has to be removed and disposed of.
• the object of the present invention was therefore to provide storage-stable, pressure-sensitive laminate sections, in particular storage-stable TTS products, in which or during their production the disadvantages known from the prior art are avoided.
• This cover strip is preferably formed so that it completely covers the cut in the protective film and is coated on one side with adhesive so that it adheres to the protective film.
• the cover strip is mounted so that it does not affect the function of the cut in the actual protective film as a peel off. That the cover strip is not completely coated with adhesive, and the adhesive coated part is only on one side of the cut. Preferably, therefore, the cover film is provided only about half of its width with adhesive.
• any suitable adhesive may be used for the cover strip, such as e.g. Pressure-sensitive adhesive based on natural and synthetic rubbers,
• Polyacrylates polyesters, polychloroprenes, polyisobutenes, polyvinyl ethers and
• Polyurethanes which are used in combination with additives such as resins, plasticizers and / or antioxidants.
• a silicone adhesive is used. This applies in particular to TTS products according to the invention, since most active pharmaceutical ingredients have only a very low solubility in these silicone adhesives exhibit.
• the back of the cover strip is coated with a barrier layer which can not stick to the adhesive of the cover strip. This is especially true for TTS products with silicone adhesive coated cover strips. Suitable materials for such barrier layers are, for example, polyethylene terephthalates and polyethylenes.
• the size of the cover film corresponds to the size of the actual protective film, which in turn may be larger than the actual laminate section or the matrix.
• the protective film and covering film project beyond the actual laminate section at its edges; this can serve as an additional removal aid for the protective film and also corresponds to a preferred embodiment of the present invention.
• cut in the actual protective film is to be interpreted broadly, i. he is not, for example limited to one straight cut per laminate section. Rather, all geometric shapes and patterns (e.g., multiple cuts) are included here. Examples of this are disclosed in DE 3344335 A1. The cover film or the areas of its adhesive coating are then adjusted accordingly.
• the present invention thus comprises pressure-sensitive laminate sections of any type (such as, for example, adhesive plaster, pressure-sensitive adhesive labels, self-adhesive stamps, etc.), preferably in the form of a TTS.
• These sections typically consist of multiple layers and comprise a matrix (with or without a backing layer) with a pressure-sensitive side or layer, adjacent thereto a cut protective film and thereon an adhesive-coated cover film which preferably completely covers the cut.
• TTS such a laminate section generally comprises a backing layer, an active substance-containing pressure-sensitive adhesive matrix (possibly with a separate pressure-sensitive adhesive layer) for application to the patient's skin, a cut protective film and a cover film with an adhesive layer.
• further layers may occur or the elements mentioned may comprise different layers.
• the present invention is can be used widely and can be used in particular with all pressure-sensitive adhesives.
• Fig. 1 shows an example of the structure of a laminate section (1) according to the invention. They mean: (2) matrix, (3) release liner, (4) adhesive layer on cover film and (5) cover film.
• the present invention also encompasses a method for producing the laminate sections or TTS products (TTS) according to the invention, comprising the steps:
• the method according to the invention is explained in more detail without being restricted to this embodiment.
• the protective film of the starting laminate now no longer serves as an intermediate carrier, which must be disposed of later, but is already part of the final product.
• the TTS laminate is pulled from a roll and initially punched from its underside (protective film side) so that the protective film is provided in the longitudinal direction with a linear cut so that the matrix and backing layer remain intact.
• a contour punching is performed by the backing layer and the matrix, wherein the protective film remains intact and then the supernatant material of back layer and matrix can be removed (grated).
• the precoated with contact adhesive cover is a narrow strip on the underside of the TTS, on the protective film, applied.
• the cover film preferably completely covers the protective film of the TTS.
• the cover film is not completely coated with adhesive in order not to adversely affect the function of the cut in the protective film as a peel-off aid.
• the preferred methods for the production of the cover film are therefore roller coating process with recessed zones from which can be produced by simple role cut the required cover strips.
• Material for the cover sheet is basically a variety of materials suitable, such as. siliconized polyethylene terephthalate, polyethylene terephthalate, polyethylene,
• the material of the cover corresponds to the material that is used for the actual protective film.
• Fig. 2 shows a possible embodiment of the manufacturing method according to the invention.
• punch for punching the protective film to produce the cut (8) preferred 1, (9) contour punch, (10) rewinder for punched grid, (11) unwinding for AbeckstMail or cover film, ( 12) laminating station, 13 (stamping punch), (14) preferred 2 and (15) cross cutter.
