Definitions
- Gas barrier films and bags are required, for example, for the provision of medical fluids buffered with bicarbonate, in particular dialysis solutions for peritoneal, acute and dialysis for the treatment of chronic renal failure using hemodialysis.
- gas barrier bags it is necessary that such gas barrier bags have a low permeation tendency of Carbon dioxide.
- gas barrier bags can also be suitable for containing enteral or parenteral nutritional solutions and suspensions.
- EP0760283A describes a multilayer film comprising a polyester or polyamide as a base material, which is provided with an inorganic SiO2 layer and which contains a second barrier layer made of PVC or a similar material.
- the adhesion of the barrier film to the inorganic SiO2 layer is to be ensured by a silane treatment of the inorganic layer.
- Such multilayer films have good water and oxygen barrier properties, but may not be mechanically stable enough to safely store medical fluids. Such films are also difficult to weld, which may result in low weld seam strength. Depending on the layer sequence, these films also have poor values for the leachability of residual monomer components such as caprolactam.
- the invention is therefore based on the object of reducing the disadvantages of the prior art.
- it is an object to ensure a mechanically stable film with a low transfer of residual monomers and other undesirable substances to the medical liquid.
- It is also an object to provide a bag comprising a film according to the invention which reduces the disadvantages of the prior art.
- Such a medical liquid can be a solution, in particular an aqueous solution, optionally comprising ionic and/or non-ionic water-soluble components, further in particular the medical liquid can contain carbonate components.
- a multilayer film is also preferably used for medical liquids that are sensitive to the introduction of carbon dioxide from the atmosphere into the liquid.
- solutions containing carbonate or hydrogen carbonate it can also be desirable to minimize the loss of carbonate or hydrogen carbonate ions from the solution.
- a peel seam can then be created simply by welding a surface at a defined temperature, so that on the one hand the multilayer film can be processed into a multi-chamber bag with different medical fluids, but on the other hand it is possible to break the peel seam before using the medical fluids in the respective chambers and to enable different medical fluids to be mixed shortly before use.
- This is particularly desirable when medical fluids can be stored for a long time as separate solutions, but only have a limited shelf life after mixing.
- olefinic polymers in direct contact with medical fluids is preferred because they are particularly physiologically safe.
- Such multi-chamber bags are used in particular for the storage of medical dialysis solutions, and in particular for dialysis solutions for peritoneal dialysis.
- the multilayer gas barrier film is characterized in that the middle film comprises a polyethylene terephthalate or a polyethylene naphthalate or a mixture of both polymers.
- the middle film comprises a polyethylene terephthalate or a polyethylene naphthalate or a mixture of both polymers.
- These polymers can withstand high mechanical stresses, are easy to extrude as a film and have particularly suitable properties with regard to the diffusion of carbon dioxide.
- Polyethylene terephthalate is particularly preferred because it can provide good adhesion for the inorganic layer.
- the multilayer gas barrier film is characterized in that the sixth surface is in contact with the surrounding atmosphere.
- the film is designed such that no further layer is required to provide the overall property profile.
- a polyamide film made of polyamide 6 is produced as a cast film with biaxial stretching.
- the layer thickness is 15 pm.
- the SiOx layer is applied by means of electron beam evaporation, whereby the layer thickness of the inorganic layer is approximately 50 nm.
- the production of the layer is described in more detail in DE102012018525A.
- the outer layer of the polyolefin film - consisting of polypropylene - is wetted with a solvent-based polyurethane adhesive, the layer is pre-dried in a heating channel.
- the PET(SiO)x layer is then laminated onto it in a roll laminator.
- the multilayer gas barrier film is manufactured as in Example 1 with the following difference:
- the outer layer of the polyolefin film - consisting of polypropylene - is wetted with a solvent-based polyurethane adhesive, the layer is pre-dried in a heating channel.
- the PA6 layer is then laminated on top in a roll laminator.
- a further polyurethane adhesive layer is then applied and dried again.
- the PET-SiOx film is then laminated on top. The SiOx layer comes into contact with the adhesive layer.
- a solution is prepared which may be suitable for performing peritoneal dialysis.
- the concentrations are as follows:
- the aluminum content is determined using the well-known measuring method ICP mass spectroscopy.
- a bag is made from the respective film by firmly welding the edges.
- a filling tube is inserted into the upper area and sealed tightly, as is the case with the bags that are available as standard under the name sleep safe BicaVera 5000 ml from Fresenius Medical Care.
- This bag is then stored at 40°C and ⁇ 25% relative humidity for 3 months.
- the CO2 permeability is measured on a film section that has previously been sterilized in steam at 120°C for 20 minutes using a test device in accordance with DIN 53380-4 at 23°C and 0% relative humidity. All films have a permeability of less than 20cm 3 /m 2 *d*bar and are therefore suitable for containing solutions containing hydrogen carbonate.
