Definitions

• Coated aluminum foil with improved cold deformation behavior and packaging made using this aluminum foil made using this aluminum foil.
• the invention relates to a coated aluminum foil with improved cold deformation behavior and to a pack, in particular a push-through or blister pack, produced using such an aluminum foil.
• Blister packs or blister packs generally consist of a carrier body made of flat material, which has a plurality of depressions made by deforming this material for receiving the packaged goods, in particular tablets, capsules and the like, within a flat area, and which is flat in this flat area with an aluminum Closure film is connected.
• the carrier body material in many cases consists of a plastic film, e.g. from a PVC film with a thickness in the range of approximately 0.2 to 0.3 m, in which the depressions are produced by a hot-forming process.
• such a composite film consists, for example, of 0.025 mm OPA (oriented polyamide) 0.045 mm aluminum and 0.060 mm PVC Giving support body ei increased strength and - it is assumed - prevent the occurrence of expansion peaks in the aluminum foil in the cold forming process, which can lead to their tearing.
• the cold-forming ability of the composite material mentioned is higher than that of an equivalent normal aluminum foil.
• carrier bodies for blister packs have the disadvantage that they do not comply with the current disposal regulations, according to which empty packs of this type may only be disposed of as a whole if they consist of at least 90% by weight of a uniform material.
• the aluminum content is z. only about 57%.
• the use of pure aluminum foils as carrier bodies in the case of push-through or blister packs has hitherto not been considered practically possible.
• the invention is based on the object of specifying aluminum foils with a relatively thin coating which have improved cold deformability and which are particularly suitable as a material with high gas tightness for carrier bodies in blister packs.
• the aluminum foil coated according to the invention in that the aluminum foil has a thickness in the range from 0.05 to 0.3 mm and in that the coating surface on the die side has a coefficient of friction in the range of at most 0.35 measured according to Briti Standard (BS) 2782 , but advantageously of at most 0.3 and / or that the coating surface on the male side of the Aluminum foil have (has) a maximum of 0.45, but advantageously a maximum of 0.40.
• BS Briti Standard
• the surface on the die side advantageously consists of a plastic layer.
• the plastic layer on the male side is heat-sealable and has a thickness in the range from 0.001 to 0.030 mm. According to a further advantageous embodiment, this thickness is in the range from 0.003 to 0.020 mm, but advantageously in the range from 0.003 to 0.012 mm.
• this is characterized in that the synthetic resin layer on the die side consists of a thin protective lacquer layer with a thickness in the range from 0.0005 to 0.020 mm.
• the invention further relates to a pack with high gas-tightness, in particular a blister pack with a carrier body made of flat material, which has a plurality of depressions made by deformation of this material for receiving the packaged goods, in particular tablets, capsules and the like, within a flat area, and the is flatly connected with an aluminum sealing film in this flat area, the aluminum content of the empty pack being intended to make up as high a percentage as possible.
• a pack with high gas-tightness in particular a blister pack with a carrier body made of flat material, which has a plurality of depressions made by deformation of this material for receiving the packaged goods, in particular tablets, capsules and the like, within a flat area, and the is flatly connected with an aluminum sealing film in this flat area, the aluminum content of the empty pack being intended to make up as high a percentage as possible.
• the carrier body consists of one piece and that the depressions are formed by cold-forming processes and are provided on at least their concave side with a sealable plastic layer and that the carrier body is made of a coated aluminum foil according to the Invention is made, wherein the aluminum content of the empty pack is more than 80 wt.%, But advantageously more than 90 ge.%.
• Fig. 1 shows the pack in supervision.
• Fig. 2 shows a schematic sectional view along lines II-II in Fig. 1;
• Fig. 3 shows a partial representation to indicate the manufacturing process.
• the carrier body 1 is produced from a cold-formable aluminum strip with a thickness in the range from 0.05 to 0.3 mm and a quality according to the Aluminum Association (AA) 8079 or 8008.
• This aluminum strip is provided on the male side with a sealable plastic layer 2, in particular in the form of a heat seal lacquer, with a thickness of 0.001-0.030, preferably 0.003-0.012 mm, and has e.g. a protective lacquer layer (not shown).
• the application amount of the protective lacquer layer is, for example, 2 g / m.
• the cups 3 are then filled on the belt with the packaged goods, for example tablets 4, and with an aluminum sealing film 5 with a thickness of 0.01-0.04 mm (in this example, 0.02 mm), which is on the underside a heat seal layer, preferably in the form of a heat seal lacquer coating 6, which has a thickness of 0.003-0.020 mm (in this example, 0.009 mm), on the undeformed regions of the carrier body material 7, as indicated by the arrows 8 in FIG. 3 Heat seal connected.
• the tape-like composite thus produced which already contains the packaged goods, is perforated in a punctiform manner at the lines 9 and the packs are finally separated along their contour 10 by punching.
• FIG. 1 in which the finished package is shown with an aluminum sealing film 5 broken open on a well 3, the area of the seal 11 can be seen (dotted).
• the pack can be subdivided in any way at the perforations along the lines 9.
• the aluminum content of the empty pack (carrier body plus sealing film) is 94% by weight in this example.
• coated aluminum foil according to the invention is advantageously suitable as packaging material for blister packs or blister packs which are used in pharmacy and which can easily be disposed of as empty packs.
