Definitions

  • the present invention relates to a method for producing a pharmaceutical blister pack, preferably a pharmaceutical push-through blister pack, said pack comprising a carrier layer having an upper exterior surface and a lower exterior surface, in which carrier layer a plurality of cavities for receiving a pharmaceutical product are formed, and a sealing layer, which sealing layer is bonded to the upper exterior surface of the carrier layer in order to seal said cavities .
  • a blister pack is any of several types of pre-formed plastic packaging.
  • the primary component of a blister pack is a cavity or pocket formed in a formable web, which web is usually made of a thermoformed plastic.
  • the blister usually has a seal of aluminum or plastic foil.
  • Blister packs are useful for protecting products against external factors, such as oxygen and water vapor and contamination for extended periods of time. Non-transparent blisters also protect light-sensitive products. Blister packs are usually used to package products such as medicine, foods, toys, hardware etc.
  • thermoforming or cold forming.
  • the main advantages of (thermoformed) plastic-based blister packs are their more compact size compared to cold-formed aluminum blister packs, as well as their transparency which allows the user to see the product held in the cavities. For this reason, when it comes to pharmaceutical products, thermoformed blister packs are considered to be elderly-friendly as compared to cold-formed blister packs with regard to so-called compliance.
  • patient compliance also adherence, capacitance
  • adherence refers to the degree to which a patient correctly follows medical advice. Most commonly, it refers to the ability of the patient to take medications as prescribed by their physician with regards to the correct drug, dose, route, timing, and frequency.
  • non-compliance is seen to be a major obstacle to the effective delivery of health care. According to the WHO, only about 50% of patients with chronic diseases living in developed countries follow treatment recommendations. Major obstacles to compliance are believed to include the complexity of modern medication regimens, the high number of different medications prescribed simultaneously, and poor health literacy.
  • blister packs holding pharmaceutical products usually contain certain information and indications allowing the user to take his or her medicine as prescribed.
  • information is usually contained in the PIL (patient information leaflet), while some basic information is usually printed on a sealing layer of the (thermoformed) blister pack.
  • PIL patient information leaflet
  • sealing layer of the (thermoformed) blister pack.
  • the user gradually destroys this sealing layer, thereby rendering more and more of the information printed thereon indecipherable.
  • the information that has to be conveyed to the user must be contained on the sealing layer redundantly, i.e.
  • the individual units of printed user information contained on the sealing layer are rather small, which makes it even more difficult for users to properly read it. Also, in general the amount of information which can be printed on the sealing layer is rather small due to obvious technical reasons.
  • a method for producing a pharmaceutical blister pack preferably a pharmaceutical push-through blister pack, said pack comprising a carrier layer having an upper exterior surface and a lower exterior surface, in which carrier layer a plurality of cavities for receiving a pharmaceutical product are formed, and a sealing layer, which sealing layer is bonded to the upper exterior surface of the carrier layer in order to seal said cavities, wherein the method comprises at least the following steps: providing a decor layer and bonding the decor layer to the lower exterior surface of the carrier layer before the cavities are formed in the carrier layer.
  • the blister pack obtained from the method according to the present invention makes it possible to use not only the upper exterior surface of the carrier layer to convey important information to the user (as described above), but to include such information or indications also on the lower exterior surface of the carrier layer.
  • the carrier layer - and therefore also its lower exterior surface - is deformed and becomes uneven when the cavities are (thermo)formed, printing directly on the lower exterior surface of the carrier layer is usually avoided.
  • Such a print applied directly to the carrier layer could also lead to a risk of contamination of the pharmaceutical product which is enclosed in the cavities later on (contamination transfer could take place in the reel of the carrier layer from the lower exterior surface of one reel layer to the upper exterior surface of the next reel layer).
  • an additional layer i.e. the decor layer
  • attaching said decor layer to the lower exterior surface of the carrier layer, it becomes possible to use (also) the lower exterior surface for displaying important information to the end user without risking contamination.
  • the design of the decor layer - and with it at least some of the indications contained thereon - is altered by the subsequent forming of the cavities, this does not prevent the decor layer from being able to convey the information expressed by its design to the user.
  • a decor layer which is full-surface bonded to the lower exterior surface of the carrier layer and/or in case of a decor layer which covers (substantially) the entire lower exterior surface of the carrier layer, it has been observed that the uniform and periodic distortions of the decor layer do not (substantially) impede its capability to convey the information encoded on the decor layer to the user.
  • the carrier layer - in contrast to the sealing layer - is not destroyed (i.e. torn) when the user presses out tablets from the blister pack, there is no need to design the decor layer in such a way that the information for the user is contained therein redundantly, i.e. multiple times.
  • indications e.g. pictograms, which are sized in such a way that they cover multiple (or even a majority of the) cavities or even all cavities. This additionally increases user/drug safety and therapy compliance.
  • the lower surface of the blister pack for displaying indications, which indications are easily recognizable for the end user, and which indications are (essentially) maintained even after the user has pressed out (one, some, or even all of) the tablets contained in the cavities.
  • the invention thus facilitates compliance and safety, especially with regard to pharmaceutical products but also foods, etc.
  • the decor layer has a printed exterior surface which is covered, at least partially, with a print.
  • the decor layer has only the one printed exterior surface which is covered, at least partially, with a print, whereas an exterior surface of the decor layer opposite the printed exterior surface is not covered with a print.
  • the print comprises printed text, pictograms, and/or other printed symbols.
  • a heart pictogram for a medication used to treat heart conditions, on the decor layer has been found to boost compliance and drug safety, in particular with elderly patients.
  • the use of such pictograms has been found to drastically reduce the risk of mistakes and mix-ups since the patient may easily identify the respective medication based on the pictogram. Similar effects have been observed using other simplified symbols instead of or in addition to the usual text.
  • the print comprises signs or indications designating the kind, intended purpose, dosage, and/or other characteristics of the pharmaceutical product. It is also possible, however, that the print comprises marketing messages or marketing symbols.
  • the printed signs or symbols may help the patients (or users) to safely identify the kind (e.g. tablet, capsule, etc.), the purpose (e.g. treatment of heart condition, hypertension, pain treatment, etc.), the dosage (once, twice, three times a day, etc.), the time of day, or the way to take the medication (e.g. with the meal, with some water, chew or suck, etc.). In this way, compliance and drug safety may be further improved.
  • the kind e.g. tablet, capsule, etc.
  • the purpose e.g. treatment of heart condition, hypertension, pain treatment, etc.
  • the dosage once, twice, three times a day, etc.
  • the time of day e.g. with the meal, with some water, chew or suck, etc.
  • the decor layer is bonded to the carrier layer in such a way that the printed exterior surface of the decor layer faces the carrier layer, preferably the lower exterior surface of the carrier layer.
  • the print is protected from mechanical, thermal and chemical influences. This protects the print during the (thermo)forming step, i.e. during the formation of the cavities in the multilayer composite, during the sealing step, i.e. during the bonding of the sealing layer to the carrier layer holding the pharmaceutical product in its cavities, and during the intended use by the user.
  • the (optical) quality of the print is improved in this embodiment.
  • a shiny effect can be achieved and/or improved by "sandwiching" the printed exterior surface inside the multilayer composite and there is no need for an additional layer of ink (over print varnish).
  • a thickness of the decor layer is smaller than a thickness of the carrier layer.
  • a thickness of the carrier layer is between 50 ⁇ m and 1.000 ⁇ m, in particular between 200 ⁇ m and 300 ⁇ m, more particularly 250 ⁇ m, and/or a thickness of the decor layer is between 5 ⁇ m and 500 ⁇ m, in particular 10 ⁇ m and 70 ⁇ m, more particularly 40 ⁇ m.
  • the carrier layer's thickness guarantees the desired haptic properties of the blister pack during intended use (i.e. pressing out the tablets contained in the cavities) and also a certain degree of protection against physical influences (e.g. deformation, damage), the decor layer's thickness is chosen such that the information to be conveyed to the end user can be recognized clearly over the whole extension of the decor layer.
  • the decor layer is made of an optically transparent material.
  • the carrier layer can be made of all types of deep-forming foils, including coldforming foil, or its components e.g. PVC, PVDC, PE, Aclar ® (Honeywell), PA, Aluminium, PP and PET including all laminates and combinations (also extruded materials) with this materials in different thicknesses and including all possible coatings, e.g. with ALOx, SiOX, EVOH.
  • the carrier layer is realized as a PVC foil.
  • a carrier layer consisting of (or comprising) PVC polyvinyl chloride
  • PVC polyvinyl chloride
  • a carrier layer made of (or comprising) PVC facilitates the bonding of additional functional layers to the carrier layer, e.g. functional layers such as PVDC or Aclar ® layers for improved permeability protection.
  • the decor layer can be made of several crude oil based, cellulose based and Polyactide based films, such as: cPA, PET GAG, cPP, OPS and other materials. According to a preferred embodiment, however, the decor layer is realized as a cast PA foil.
  • an amount of ink transferred to the decor layer when applying the print to the printed exterior surface is a function of a cavity depth of the cavities, which cavities are to be formed in the carrier layer.
  • the amount of transferred ink increases with cavity depth.
  • the quality of the print can be kept constant for various blister packs.
  • indications printed on the decor layer appear in the same quality for various cavity forms and sizes. This allows to produce different blister packs with a uniform appearance.
  • the decor layer is bonded to the lower exterior surface by means of lamination using an adhesive.
  • This embodiment provides for a particularly simple method of bonding the two layers (carrier and decor) together; surprisingly, this bonding method does not impair the (optical) quality of the final blister pack, in particular when the decor layer is bonded to the carrier layer with its printed exterior surface facing the carrier layer.
  • the adhesive is a two-component solvent-based adhesive, preferably with isocyanate as a first component and polyol as a second component.
  • Such adhesives give superb bond strength and are particularly well suited for bonding a thick layer (carrier layer) and a thin layer (decor layer).
  • carrier layer thick layer
  • decor layer thin layer
  • this adhesive is well suited for thermoforming, or deep drawing applications.
  • a grammage of adhesive per square meter used in the lamination process is between 0,5 g/m 2 and 20 g/m 2 , in particular between 3 g/m 2 and 5 g/m 2 , more particularly between 3,5 g/m 2 and 4,5 g/m 2 .
  • This embodiment achieves a sufficiently strong bond between the decor layer and the carrier layer, without impairing the optical quality of the decor layer on the final blister pack.
  • the obtained layer bonding (multilayer composite) is subjected to a curing process before further processing steps, in particular slitting steps, are performed.
  • a curing time of this curing process is at least 5 days.
  • the layer bonding is exposed to an ambient air temperature between 15 °C and 25 °C (at normal pressure).
  • This curing step further increases the quality of the final product, i.e. the blister pack obtained from the method.
  • the curing process may also be shorter than 5 days or omitted entirely.
  • An objective of the present invention is achieved by a method for producing a pharmaceutical blister pack, preferably a pharmaceutical push-through blister pack, said pack comprising a multi-purpose layer made of aluminum having an upper exterior surface and a lower exterior surface, in which multi-purpose layer a plurality of cavities for receiving a pharmaceutical product are formed, and a sealing layer made of aluminum, which sealing layer is bonded to the upper exterior surface of the carrier layer in order to seal said cavities, wherein a print is applied to the lower exterior surface of the multi-purpose layer before the cavities are formed in the multi-purpose layer.
  • Fig. 1-4 The method for producing a pharmaceutical blister pack according to the present invention is illustrated in Fig. 1-4 . According to the shown embodiment, the method comprises the following steps:
  • a (sheet-like) decor layer 6 is provided, preferably (reeled-up) on a reel (not depicted).
  • Said decor layer 6 is made of transparent material and has a printed exterior surface 8 carrying a print.
  • the form of the print is chosen in accordance with the producer of a pharmaceutical product 3 which is to be packed in the blister pack.
  • the print may contain or represent signs or indications designating the kind, intended purpose, dosage, and/or other characteristics of the pharmaceutical product 3, aimed at improving compliance and drug safety.
  • the decor layer 6 is bonded to a carrier layer 1, such that the printed exterior surface 8 of the decor layer 6 faces (and/or contacts) a lower exterior surface 7 of said carrier layer 1.
  • the lower exterior surface 7 is the surface of the (sheet-like) carrier layer 1 which is opposite of an upper exterior surface 5 of the carrier layer 1.
  • the main purpose of said upper exterior surface 5 is to facilitate the sealing ( Fig. 4 ) of the pharmaceutical product 3 inside cavities 2 of the blister pack (which cavities have not yet been created in Fig. 2 ).
  • the carrier layer 1 may also be provided on a reel (reeled-up) and the lamination process may thus be a reel-to-reel process, such that the resulting laminated structure is also reeled-up on a reel.
  • the cavities 2 are created.
  • the laminated structure is subjected, e.g. directly from the reel, to any kind of forming procedure, e.g. thermoforming or cold forming (or cold working).
  • the cavities 2 are established in the carrier layer 1.
  • the decor layer 6, which is bonded to (the lower exterior surface 7 of) the carrier layer 1 is given a form resembling the form of the cavities 2.
  • a laminated and formed structure is obtained.
  • the next steps of the method include positioning the pharmaceutical product 3 (here: tablets) in the cavities 2 and sealing said cavities 2 by bonding a sealing layer 4 to the upper exterior surface 5 of the carrier layer 1.
  • a sealing layer 4 is bonded to the upper exterior surface 5 in such a way that the sealing layer 4 is in (flat) contact with the upper exterior surface 5 in those regions of the carrier layer 1 surrounding the cavities 2.
  • a backside of the sealing layer 4, which is typically made of aluminum foil, may also carry a print.
  • a blister pack which - in contrast to known blister packs - may provide the user (patient) with user information not only by means of the printed sealing layer 4, which sealing layer 4 is gradually destroyed when the user presses out tablets from the blister pack, but also by means of the decor layer 6.
  • information can be conveyed to the user through text and/or symbols, which have been printed onto the decor layer 6, and can be readily recognized by the user when viewing the lower exterior surface of the blister pack.
  • the materials for the decor layer (cast PA) and the carrier layer (PVC) are provided in reels.
  • pre-press, color separation, and, for every color printing tool production steps are performed (cylinder for rotogravure and cliché for flexo printing). One printing tool is produced for each color.
  • the reels holding the material for the decor layer are reverse printed continuously (rotary technique) from reel to reel.
  • the printing ink used in this printing process is the VB 25 printing ink series from the company Siegwerk Druckmaschine AG & Co. KGaA.
  • the amount of ink which is transferred to the material for the decor layer depends on the characteristics of the deepforming step to be performed later on at the blistering line.
