Definitions

  • the invention relates to a push-through film for tamper-proof covering of product carriers, as is known, for example, from a large number of so-called blister packs.
  • Such known films for blister covers have hitherto consisted of aluminum foils, plastic-coated aluminum foils up to pure transparent or opaque plastic foils. These foils form the counterpart to the goods carrier or the so-called lower part of the packaging, which in turn can be formed from a variety of materials, for example from a stable layer of cardboard, a plastic or aluminum shell adapted to the shape of the goods or the like.
  • foils as cover for such packaging, either aluminum foils were used, as is the case in particular with the packaging of pharmaceutical products, such as tablets, ampoules or capsules, or a removal option was provided in the lower part of the packaging .
  • the object of the present invention is to provide a film for tamper-proof covers of product carriers, which can be produced from plastic and yet shows the known push-through properties of aluminum foil covers.
  • the film is an unstretched film with a plastic matrix which comprises the latter polyolefins, polyester, polystyrene or styrene copolymers and contains a particulate filler in an amount of 20 to 60% by weight, where the filler has an average particle size (measured over the largest dimension of the particle) of approx. 5 ⁇ m to approx. 100 ⁇ m and is selected so that the puncture resistance of the film is below a limit of approx. 200 N / mm (measured at a 150 ⁇ m thick film, measuring method according to DIN 53 373) is reduced.
  • This limit applies to approximately 150 ⁇ m thick foils. For significantly thinner or thicker foils, the corresponding limit values can be derived from these values. With the specified limit, it is possible to push pressure-insensitive goods through the cover film of the goods carrier, even if with some effort. In the case of more sensitive products, a lower limit value for the puncture resistance is preferably chosen, and this value is then preferably around 100 to around 200 N / mm. Lower puncture resistance may be advisable in individual cases where very pressure-sensitive goods are packed. However, it should be noted that, of course, with the reduction in puncture resistance, the protective effect of the packaging against damage to the goods themselves also decreases, so that in many cases an optimum can be seen in the previously specified numerical range from approximately 100 to approximately 200 N / mm is.
  • the so-called tear resistance determines the amount of force required to tear open a film once it has been pierced and thus release the product.
  • This property can also be influenced by the choice of the filler and its proportion in the plastic matrix, a tear strength of less than 30 N (measurement method according to DIN 53363) preferably being sought here.
  • This numerical value applies in particular to approximately 150 ⁇ m thick films, but can essentially also be applied to much thinner or thicker films.
  • a value for the tear propagation resistance which is acceptable for the handling, in particular also of pressure-sensitive goods, is between approx. 2 to 12 N, whereby again it should be noted that of course much lower values are possible, but with regard to the protection of the goods by the Any reduction limits are set.
  • a preferred range for tear resistance is in the range of 3 to 4 N.
  • the film according to the invention contains the filler as a homogeneous admixture to an already fully polymerized plastic material.
  • the filler is therefore not - as is known in connection with filler-reinforced plastics - dispersed in the polymerization reaction mixture of monomer and / or prepolymer and incorporated into the plastic matrix during the curing of the reaction mixture.
  • filler-reinforced plastics dispersed in the polymerization reaction mixture of monomer and / or prepolymer and incorporated into the plastic matrix during the curing of the reaction mixture.
  • fillers are available for the film fillers. These can be selected from inorganic and / or organic substances.
  • the organic substances are e.g. halogenated hydrocarbon polymers, in particular PTFE, polyether sulfones, which like the PTFE have a fixed point of> 300 ° C, and thermosetting plastics.
  • PTFE halogenated hydrocarbon polymers
  • polyether sulfones which like the PTFE have a fixed point of> 300 ° C
  • thermosetting plastics thermosetting plastics.
  • the substance can be selected from the series of silicas, in particular in the form of glass or quartz, silicates, in particular in the form of talc, titanates, TiO2, aluminum oxide, kaolin, calcium carbonates, in particular in the form of chalk, magnesite , MgO, iron oxides, silicon carbides, silicon nitrides, barium sulfate or the like.
  • the goods to be packaged and their sensitivity to one or the other additive to the polymer matrix will always have to be taken into account.
  • the shape of the filler particles will most likely be granular, but platelet-shaped, fibrous or rod-shaped filler particles are also possible as filler particles both as an essentially uniform shape or in a mixture with other shapes.
  • the choice of particle size is of course not insignificantly determined by the film layer thickness to be produced. It will therefore be important to ensure that the average expansion of the particles is at a clear distance from the film thickness to be produced. Average particle sizes between 20 ⁇ m and 60 ⁇ m are preferred, in particular with film thicknesses from 80 ⁇ m to 100 ⁇ m.
  • Adhesion promoters of this type are usually used in the production of filled plastics, but in which the particular strength of the material is used.
  • the aim is, of course, to ensure that the filler particles are distributed as evenly as possible in the plastic matrix and also maintained during the production process, so that auxiliary agents are preferably added; which improve the dispersibility of the filler particles in the matrix.
  • Low-melting organic substances which have great wetting ability for the filler are particularly suitable as dispersing agents.
  • Specific examples are low molecular weight polyolefin waxes.
  • the dispersing aids are preferably applied to the filler particles before they are mixed, in particular kneaded, with the granules of the matrix plastic.
  • the thickness of the film is preferably selected from 20 ⁇ m to approximately 600 ⁇ m, which on the one hand ensures sufficient stability of the film to protect the packaged goods and on the other hand keeps the forces necessary for opening the packaging within the predetermined limit, at least within it Pressure-sensitive goods can still be easily removed from the packaging by pushing through the cover film by the average buyer.
  • the film In particular in the packaging of pharmaceuticals, it is often desirable for the film to be essentially impermeable to water and steam.
  • Preferred polyolefins are seen in polypropylenes.
  • the reason for this is the particularly good physical properties of polypropylene, such as a barrier effect for water vapor, transparency, etc.
  • the average molecular weight of the polymers in the plastic matrix is preferably selected in the range from approximately 10,000 to approximately 300,000.
  • the normal seal strength may be sufficient to solve the above problem.
  • the sealing strength is too low in direct contact of the film with the lower part, the need for an additional sealing layer on the film surface may arise.
  • the film is constructed in two or more layers, the two or more layers of the film preferably being produced in a coextruded manner.
  • an outer film layer is designed as a sealing layer. This can, on the one hand, serve to improve the adhesion of the cover film to the goods carrier and, on the other hand, can have a special property for certain applications, such as e.g. a special water vapor impermeability, etc.
  • the film according to the invention is particularly suitable for producing a packaging with a lower part, which may be adapted in shape to the goods to be packaged, as a goods carrier and an upper part from the film according to the invention and already described above.
  • the lower part and the upper part are preferably produced using the same type of plastic, so that a pure product is obtained.
  • Such sorted products are particularly easy to recycle and reusable for the same purpose, which is an optimum in the packaging cycle.
  • a particularly preferred use of the films according to the invention is in the packaging of pharmaceuticals, which are in particular in ampoule, capsule or tablet form.
  • a polymer granulate is mixed with the filler components and then extruded or calendered.
  • the mixing in particular the homogenization, can be carried out by kneading using known processes, in particular twin-screw compounding.
  • twin-screw compounding can also be mixed with one another in a dry mixing process.
  • the filler particles should always be treated with dispersing aids before they are mixed with the matrix plastic.
  • the compound is melted in the extruder, at melt temperatures of approx. 220 ° C and more and at a melt pressure of up to 250 bar.
  • the melt is preferably cooled using a chill roll at 20 ° C. to approx. 40 ° C., but other cooling processes, possibly composed with a surface treatment with corona discharge, are also possible.
  • the foils are then cut and wrapped.
  • polypropylene such as Block copolymers or random copolymers
  • Block copolymers such as Block copolymers or random copolymers
  • the proportion of the fillers in the total film weight is preferably from 25 to 55% by weight. Below a filler content of 20% by weight, there is regularly no longer sufficient embrittlement of the plastic with the associated reduction in puncture resistance and tear resistance. With proportions well over 60% by weight, film production is difficult and the physical strength values are then often no longer sufficient for the typical uses.
  • the polypropylene-based foil according to the invention is also rewound for reasons of recrystallization. (The duration of post-crystallization is typically 4 to 10 days.)
  • a puncture resistance of 162 N / mm and a tear strength of 3.2 N were measured on this film.
