Description
Technical field
The utility model relates to a kind of composite membrane for packaging medicine.
Background technology
Along with China is in the fast development of pharmaceuticals industry, Medicine Packing Industry obtains huge living space.There is larger gap in the packaging quality of most domestic medical product and developed country.At present, medical bubble-cap has existed for many years in China with polyvinyl chloride, and as the material of packaged pharmaceuticals, it has good processing characteristics and drinks light and handy quality, but medicinal polyvinyl chloride exists the hidden danger in safety.First it is chloride, the pollution of chlorine how much can be subject in the medicine that the storage life is longer, this can bring very large impact on the health of people to health, secondly, medicinal polyvinyl chloride be that the transit dose of aqueous vapor and oxygen is larger, be fatal on the impact of the stability of drug quality, it substantially reduces storage and the period of guarantee of medicine, and the security of medicine also reduces.
The water resistance of existing packaging film is poor, and be not suitable for for the packaging medicine stronger to light, steam and oxygen sensitive, the scope of application is narrower.The Chinese pharmaceutical enterprises expensive drugs produced and the new drug with result for the treatment of excellence, because medicine self is to the strict demand of packing and the needs squeezed into the international market, is all rely on import to the packing material of solid drugs, causes cost too high.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of composite membrane for packaging medicine.
The utility model solves the technical scheme that its technical problem adopts: a kind of composite membrane for packaging medicine; there is basic unit; layer centered by described basic unit; the upper surface of basic unit to be aluminized layers of foil; layers of foil of aluminizing is provided with Biaxially oriented polypropylene layer; Biaxially oriented polypropylene layer is coated with protective coating layer; the lower end of basic unit is provided with polypropylene layer; the lower surface of polypropylene layer is provided with ethylene-vinyl acetate copolymer layer, and the lower surface of ethylene-vinyl acetate copolymer layer is provided with protective film.
Further, the thickness of described layers of foil of aluminizing is 0.01 ~ 0.4mm; The thickness of ethylene-vinyl acetate copolymer layer is 0.01 ~ 0.5mm; The thickness of Biaxially oriented polypropylene layer is 0.015 ~ 0.03mm; The thickness of polypropylene layer is 0.01 ~ 0.045mm.
Further, adhesive layer is equipped with between described composite membrane materials at two layers.
The beneficial effects of the utility model are: the utility model structure is simple, has moisture resistance, the transparency, air-tightness and hot blast good, is applicable to the kept dry of medicine, reduces costs.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Tu Zhong 1. basic unit, 2. ethylene-vinyl acetate copolymer layer, layers of foil of 3. aluminizing, 4. Biaxially oriented polypropylene layer, 5. protective coating layer, 6. polypropylene layer, 7. protective film.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of composite membrane for packaging medicine as shown in Figure 1; layer centered by basic unit 1; the upper surface of basic unit 1 to be aluminized layers of foil 3; layers of foil of aluminizing 3 is provided with Biaxially oriented polypropylene layer 4; Biaxially oriented polypropylene layer 4 is coated with protective coating layer 5; the lower end of basic unit 1 is provided with polypropylene layer 6, and the lower surface of polypropylene layer 6 is provided with ethylene-vinyl acetate copolymer layer 2, and the lower surface of ethylene-vinyl acetate copolymer layer 2 is provided with protective film 7.The thickness of layers of foil of aluminizing 3 is 0.01 ~ 0.4mm; The thickness of ethylene-vinyl acetate copolymer layer 2 is 0.01 ~ 0.5mm; The thickness of Biaxially oriented polypropylene layer 4 is 0.015 ~ 0.03mm; The thickness of polypropylene layer 6 is 0.01 ~ 0.045mm, is equipped with adhesive layer between composite membrane materials at two layers.
Concrete Biaxially oriented polypropylene layer 4 and ethylene-vinyl acetate copolymer layer 2 have stronger heat resistance, certain rub resistance, puncture-resistant performance, to its protective effect of intermediate layer, layers of foil of aluminizing 3 has good lucifuge performance, effectively can stop the infiltration of inside and outside gas or liquid, polypropylene layer 6 has chemical inertness, nontoxic, good heat sealability, mechanical strength and heat resistance, adhesive layer is provided with between composite membrane materials at two layers, be coated with between materials at two layers, by surperficial cohesive force and the intensity of itself, adjacent bi-material is bonded together, Biaxially oriented polypropylene layer 4 can carry out flexographic printing, print surface scribbles one deck water white oil polish protective coating layer 5, print gloss can be increased.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
