Abstract
The utility model relates to a packaging material, in particular to a composite film for packaging a medicine. The composite film comprises an aluminum plated polyester layer which is used as a base layer; a polyester layer is adhered to the outer surface of the aluminum plated polyester layer; and a polyethylene layer is adhered to the inner surface of the aluminum plated polyester layer. The composite film is high in waterproofness, light stopping property, flavor preservation property, light-shielding property and thermal resistance, can be used for new medicines which are sensitive to light, water vapor and oxygen, and can prevent active substances in components of medicines from being decomposed and reduce production cost.
Description
Technical field
The utility model relates to a kind of packaging material, especially a kind of medicine packaging composite film.
Background technology
Along with the fast development of China in pharmaceuticals industry, medical packaging has already obtained huge living space.There are bigger gap in the packaging quality of domestic majority 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 drug, it has good processing properties and drinks light and handy quality, but there is the hidden danger on the safety in medicinal polyvinyl chloride.At first it is chloride; What can receive the pollution of chlorine in long medicine of storage life, and this health to the people can bring very big influence to healthy, next; Medicinal polyvinyl chloride be that the transit dose of aqueous vapor and oxygen is bigger; Influence to the stability of drug quality is fatal, and it has shortened the storage and the period of guarantee of medicine greatly, and the security of medicine has also reduced.
Chinese patent number 00228778.1 discloses a kind of environment-friendly type composite package film; It is to be processed by three layers of composite membrane; Its intermediate layer is a pure aluminum foil; A surface scribbles heat-sealing adhesive, and 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 being used for packing the medicine stronger to light, steam and oxygen sensitive property, and the scope of application is narrower.The new drug that the expensive drugs that Chinese pharmaceutical enterprises is produced is excellent with having result of treatment because medicine self is to the strict demand of packing and the needs that squeeze into the international market, all is to rely on import to the packing material of solid drugs, causes cost too high.
The utility model content
The technical problem that the utility model will solve is: overcome the deficiency in the prior art, a kind of medicine packaging composite film 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 property.
The utility model solves the technical scheme that its technical problem adopted: a kind of medicine packaging composite film; Has the aluminum polyester layer; Described aluminum polyester layer is a 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 has polyethylene layer.
Further, be attached with adhesive layer between the described aluminum polyester layer of the utility model and polyester layer and the polyethylene layer.
Further, the described aluminum polyester layer thickness of the utility model 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 beneficial effect of the utility model is: have water proofing property, resistance photosensitiveness, protect the flavor property, light-proofness, resistance be hot strong.Can be used for the new drug stronger, can stop the decomposition of active material in the medicine composition, reduce production costs light, steam and oxygen sensitive property.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. aluminum polyesters among the figure, 2. polyester layer, 3. polyethylene layer.
The specific embodiment
Combine accompanying drawing that the utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of medicine packaging composite film as shown in Figure 1 has aluminum polyester layer 1, and aluminum polyester layer 1 is a 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 has polyethylene layer 3.Be attached with adhesive layer between aluminum polyester layer 1 and polyester layer 2 and the polyethylene layer 3, the adhesive of the utility model is prepared as the nano silicon oxide that in the organic solvent-free polyurethane adhesive, adds 5wt%, evenly stirs.Avoided trace solvent residual in the product, medicine pollutes, and the security of medicine has also reduced.Water proofing property, resistance photosensitiveness, to protect flavor property, light-proofness, resistance hot 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-mentioned embodiment is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
