Abstract
The utility model relates to a packaging material, in particular to a composite membrane for packaging dugs, which comprises a biaxially oriented polypropylene layer, a vacuum aluminum coated layer and a curtain coating polypropylene layer, wherein the vacuum aluminum coated layer is a central layer, and the biaxially oriented polypropylene layer and the curtain coating polypropylene layer are attached to the two sides of the vacuum aluminum coated layer. The composite membrane for packaging the dugs is high in moisture resistance, transparency, air impermeability and heat sealing performance and is applicable to dry storage of the drugs.
Description
Technical field
The present invention relates to a kind of packaging material, especially a kind of composite membrane of packing medicine.
Background technology
Along with the fast development of China in pharmaceuticals industry, Medicine Packing Industry has obtained huge living space.There are 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 there is the hidden danger on safety in medicinal polyvinyl chloride.At first it is chloride, what can be subject to the pollution of chlorine in long medicine of storage life, this health on the people can bring very large impact to healthy, secondly, medicinal polyvinyl chloride be that the transit dose of aqueous vapor and oxygen is larger, impact on the stability of drug quality is fatal, and it has shortened storage and the period of guarantee of medicine greatly, and the security of medicine has also reduced.China Patent No. 00228778.1 discloses a kind of environment protection composite package film, it is to be made by sandwich diaphragm, its intermediate layer is pure aluminum foil, a surface scribbles heat-sealing adhesive, another surface is compound with paper substrate, and heat-sealing adhesive is to be mixed by acrylic resin, vinyl chloride, acetate ethylene copolymer.The shortcoming of its existence is: the water resistance of this packaging film is relatively poor, is not suitable for packing the medicine stronger to light, steam and oxygen sensitive, and the scope of application is narrower.The expensive drugs that Chinese pharmaceutical enterprises is produced and the new drug with result for the treatment of excellence to the strict demand of packing and the needs that squeeze into the international market, all are to rely on import to the packing material of solid drugs due to medicine self, cause cost too high.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, the composite membrane of the high packing medicine of a kind of moisture resistance, the transparency, air-tightness, printed form and heat seal strength is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of composite membrane of packing medicine, have Biaxially oriented polypropylene layer, vacuum aluminium coated layer and cast polypropylene layer, described centered by vacuum aluminium coated layer the layer, the two sides is attached with respectively Biaxially oriented polypropylene layer and cast polypropylene layer.
Further, vacuum aluminium coated layer of the present invention is attached with adhesive layer.
Further, vacuum aluminum-coated layer thickness of the present invention is 0.01～0.05mm, and the Biaxially oriented polypropylene layer thickness is 0.015～0.03mm, and described cast polypropylene layer thickness is 0.01～0.05mm.
The invention has the beneficial effects as follows: moisture resistance of the present invention, the transparency, air-tightness and hot blast are acted charitably, and are applicable to the kept dry of medicine.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
1. Biaxially oriented polypropylene layers in figure, 2. vacuum aluminium coated layer is 3. with the cast polypropylene layer.
The specific embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of composite membrane of packing medicine as shown in Figure 1 has Biaxially oriented polypropylene layer 1, vacuum aluminium coated layer 2 and cast polypropylene layer 3, layer centered by vacuum aluminium coated layer 2, and the two sides is attached with respectively Biaxially oriented polypropylene layer 1 and cast polypropylene layer 3.Vacuum aluminium coated layer 2 be attached with adhesive layer.Adhesive of the present invention is prepared as the nano silicon oxide that adds 5wt% in the organic solvent-free polyurethane adhesive, uniform stirring.Avoided trace solvent residual in product, medicine pollutes, and the security of medicine has also reduced.Moisture resistance, the transparency, air-tightness and hot blast are acted charitably, and are applicable to the kept dry of medicine.So selecting vacuum aluminium coated layer 2 thickness is 0.012mm, Biaxially oriented polypropylene layer 1 thickness is 0.02mm, and cast polypropylene layer 3 thickness are 0.015, can save cost.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
