Abstract
The invention relates to a packaging material, and especially relates to a composite film for medicine packaging. The composite film comprises an aluminized polyester layer which is a base layer, the external surface of the aluminized polyester layer is attached with a polyester layer, and the internal surface of the aluminized polyester layer is attached with a polyethylene layer. The composite film has strong water prevention, light blocking, taste retention, light shielding and heat insulating properties, can be used for packaging new medicines highly sensitive to light, water vapor and oxygen, can prevent the decomposition of active substances in the components of medicines, and reduces the production cost.
Description
Technical field
The present invention relates to a kind of packaging material, especially a kind of pharmaceutical packaging composite membrane.
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, a kind of pharmaceutical packaging composite membrane is provided, water proofing property, the barrier of this packaging film are strong, can be used for packing the medicine stronger to light, steam and oxygen sensitive.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pharmaceutical packaging composite membrane, has the aluminum polyester layer, described aluminum polyester layer is basic unit, and the outer surface of aluminum polyester layer is attached with polyester layer, and the inner surface of aluminum polyester layer adheres to polyethylene layer.
Further, be attached with adhesive layer between aluminum polyester layer of the present invention and polyester layer and polyethylene layer.
Further, aluminum polyester layer thickness of the present invention is 0.01～0.03mm, and described polyester layer thickness is 0.015～0.03mm, and described polyethylene layer thickness is 0.02～0.05mm.
The invention has the beneficial effects as follows: the present invention has water proofing property, resistance photosensitiveness, protects the flavor property, light-proofness, thermal resistance are strong.Can be used for the new drug stronger to light, steam and oxygen sensitive, can stop the decomposition of active material in the medicine composition, reduce production costs.
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. aluminum polyesters in figure, 2. polyester layer, 3. polyethylene 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 pharmaceutical packaging composite membrane as shown in Figure 1 has aluminum polyester layer 1, and aluminum polyester layer 1 is basic unit, and the outer surface of aluminum polyester layer 1 is attached with polyester layer 2, and the inner surface of aluminum polyester layer 1 adheres to polyethylene layer 3.Be attached with adhesive layer between aluminum polyester layer 1 and polyester layer 2 and polyethylene layer 3, 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.Water proofing property, resistance photosensitiveness, to protect flavor property, light-proofness, thermal resistance strong, and aluminum polyester layer 1 thickness is 0.01～0.03mm, and polyester layer 2 thickness are 0.015～0.03mm, and polyethylene layer 3 thickness are 0.02～0.05mm.
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.
