Abstract
The utility model discloses a kind of medical packaging composite membrane, its drip irrigation device is: comprise the first antibiotic layer, pet layer, soft aluminium foil layer, PA66 layer, CPP layer, high-temperature-resistant layer and the second antibiotic layer that set gradually.The utility model solves the problem that heat-resisting quantity is poor, antibiotic property is poor and intensity is low of existing medical packaging composite membrane.
Description
Technical field
The utility model relates to a kind of composite membrane, and in particular, it relates to a kind of medical packaging composite membrane.
Background technology
Composite membrane is the staple product in Key works Drug packing field, be widely used in the medicine packing various formulation, existing medical packaging composite membrane in process of production can through disinfecting, such as carry out disinfection with oxirane or gamma-rays, or high-temperature sterilization, but because the heat-resisting quantity of existing medical packaging composite membrane is poor, so the temperature of sterilization can not be too high, otherwise medical packaging composite membrane can be caused to be burnt out by high temperature, the Disinfection Effect so just do not reached, so the heat-resisting quantity of existing medical packaging composite membrane need to improve.Secondly, after sterilizing above, medical packaging composite membrane is in transport, sale and use procedure, bacterium still can be attached to inner surface or the outer surface of packaging composite film, pollute, may drug effect be affected, so the antibiotic property of existing medical packaging composite membrane need to improve.Moreover existing medical packaging composite membrane exists the lower shortcoming of intensity, so medical packaging composite membrane can be caused to break or damage, medicine so will be caused to be polluted, so existing medical packaging compound film strength need to improve.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of high temperature resistant, antibiotic property good and intensity is high medical packaging composite membrane.
For achieving the above object, the utility model provides following technical scheme: a kind of medical packaging composite membrane, comprises the first antibiotic layer, pet layer, soft aluminium foil layer, PA66 layer, CPP layer, high-temperature-resistant layer and the second antibiotic layer that set gradually.
Preferably, described first antibiotic layer or the second antibiotic layer are nano-silver layer.
Preferably, described high-temperature-resistant layer is high temperature resistant food grade polyurethane adhesive layer.
Preferably, the thickness of described first antibiotic layer is between 0.1 micron to 2 microns.
Preferably, the thickness of described pet layer is between 1 micron to 18 microns.
Preferably, the thickness of described soft aluminium foil layer is between 5 microns to 20 microns.
Preferably, the thickness of described high-temperature-resistant layer is between 0.1 micron to 2 microns.
Preferably, the thickness of described second antibiotic layer is between 0.1 micron to 2 microns.
Preferably, the thickness of described second antibiotic layer is 1 micron.
The utility model has following advantage: the utility model medical packaging composite membrane is after making packaging bag, and the first antibiotic layer can have antibacterial effect to packaging bag inner surface, and the second antibiotic layer can have antibacterial effect to packaging bag outer surface.Pet layer, soft aluminium foil layer, PA66 layer and the puncture strength of CPP layer after compound are high, not easily occur slight crack, have excellent barrier property, toughness and rigidity, make this medical packaging composite membrane be not easy to break or damage.Moreover this medical packaging composite membrane is when carrying out high-temperature sterilization, and high-temperature-resistant layer can play a protective role to it, prevent this medical packaging composite membrane from being burnt out by high temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model medical packaging composite membrane.
In figure: 1, the first antibiotic layer; 2, pet layer; 3, soft aluminium foil layer; 4, PA66 layer; 5, CPP layer; 6, high-temperature-resistant layer; 7, the second antibiotic layer.
Detailed description of the invention
With reference to shown in accompanying drawing, the utility model medical packaging composite membrane is further illustrated.
Embodiment: a kind of medical packaging composite membrane, comprises the first antibiotic layer, pet layer, soft aluminium foil layer, PA66 layer, CPP layer, high-temperature-resistant layer and the second antibiotic layer that set gradually, can be bonding by bonding agent between each layer.It is as follows that the effect sequentially can brought is set between each layer above, medical packaging composite membrane is after making packaging bag, first antibiotic layer can have antibacterial effect to packaging bag inner surface, pet layer, soft aluminium foil layer, PA66 layer and the puncture strength of CPP layer after compound are high, not easily there is slight crack, there is excellent barrier property, toughness and rigidity, make this medical packaging composite membrane be not easy to break or damage.Moreover this medical packaging composite membrane is when carrying out high-temperature sterilization, and high-temperature-resistant layer can play a protective role to each layer of inside, prevents this medical packaging composite membrane from being burnt out by high temperature.Second antibiotic layer is arranged on outside high-temperature-resistant layer can have antibacterial effect to packaging bag outer surface.
Wherein, the first antibiotic layer or the second antibiotic layer are nano-silver layer; Or the first antibiotic layer or the second antibiotic layer are nano oxidized zinc layers; Or the first antibiotic layer is nano-silver layer, the second antibiotic layer is nano oxidized zinc layers; Or the first antibiotic layer is nano oxidized zinc layers, the second antibiotic layer is nano-silver layer.The thickness of the first antibiotic layer is 0.1 micron or 1 micron or 2 microns, and the thickness of the second antibiotic layer is 0.1 micron or 1 micron or 2 microns.The antibiotic layer of such thickness can make composite membrane have stronger antibiotic property, and when the longer antibacterial cycle, production cost can be reduced in rational scope, the unlikely reduction of production efficiency, and other performances of composite membrane can remain unchanged or increase.Experiment finds, its THICKNESS CONTROL substantially can be achieved the above object within the scope of this.First antibiotic layer or the second antibiotic layer can also be the extract etc. of potassium sorbate, nisin or grape pip, or adopt the macromolecular material being mixed with Nano Silver to make.
High-temperature-resistant layer is high temperature resistant food grade polyurethane adhesive layer, and this is high temperature resistant, and food grade polyurethane adhesive layer not only has the effect that resistant to elevated temperatures effect also has adhesive, directly CPP layer and the second antibiotic layer is bonded together.
Soft aluminium foil layer is made up of the aluminium foil after annealing in process, and the soft aluminium foil layer through annealing in process has better toughness and puncture-resistant performance, not easily occurs crackle, decreases in use procedure by the situation surprisingly punctured.
PA66 layer is than common PA(such as PA6) have and better come puncture resistance and toughness.CPP layer further enhancing puncture-resistant performance, and CPP has better strength character, and the bulk strength of this medical packaging composite membrane is improved.
The thickness of pet layer is 1 micron or 9 microns or 18 microns, and the thickness of soft aluminium foil layer is 5 microns or 8 microns or 20 microns, and the thickness of high-temperature-resistant layer is 0.1 micron or 1 micron or 2 microns.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
