Abstract
The invention relates to a package material, and especially relates to a cold punching press type medicinal composite hard sheet. The invention relates to a polyamide layer, an aluminum layer and a polyvinyl chloride layer, the polyvinyl chloride layer is attached with the aluminum layer, and the aluminum layer is attached with the polyamide layer. The cold punching press type medicinal composite hard sheet has the characteristics of good waterproof resistance, gas barrier property, flavor and odor barrier property, light shading performance, thermal resistance performance, and is suitable for the package materials with high sealing performance and long shelf life of expensive medicines and new medicines, the pollution of the medicines can be avoided, the electric energy can be saved, and the pollution on air can be avoided.
Description
Technical field
The present invention relates to a kind of packaging material, especially a kind of cold stamping shaped medicinal composite hard sheet.
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 it generally adopts composite dry process aborning.Because the adhesive that uses is solvent type adhesive, therefore unavoidably there is trace solvent residual in product, when residual solvent exceeds standard be, might pollute medicine, the security of medicine has also reduced.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provide a kind of water proofing property, barrier 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 cold stamping shaped medicinal composite hard sheet, have aramid layer, and aluminum layer and polyvinyl chloride layer are attached with the aluminum layer above polyvinyl chloride layer, be attached with aramid layer above the aluminum layer.
Further, aramid layer of the present invention bonds by adhesive layer between aluminum layer and polyvinyl chloride layer.
Further, aluminum layer thickness of the present invention is 0.01～0.05mm, and described aramid layer thickness is 0.015～0.03mm, and described polyvinyl chloride layer thickness is 0.012～0.03mm.
The invention has the beneficial effects as follows: water proofing property of the present invention, gas barrier property, guarantor's flavor property, light-proofness, thermal resistance are good, be applicable to sealing high, the expensive drugs of interior medicine long shelf-life and the packaging material of new drug are stopped the pollution to medicine, can saves energy, can not pollute air.
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. aramid layers in figure, 2. aluminum layer, 3. polyvinyl chloride 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 cold stamping shaped medicinal composite hard sheet as shown in Figure 1 has aramid layer 1, and aluminum layer 2 and polyvinyl chloride layer 3 are attached with aluminum layer 2 above polyvinyl chloride layer 3, be attached with aramid layer 1 above aluminum layer 2.Aramid layer 1 bonds by adhesive layer between aluminum layer 2 and polyvinyl chloride layer 3.Good as the cold stamping performance, water proofing property, resistance photosensitiveness, to protect flavor property, light-proofness, thermal resistance strong, be calendered to 0.015mm when following, tend to occur pin hole, pin hole is more, and gas permeability is larger, barrier is poorer, so aluminium preparative layer 2 thickness are 0.012mm, aramid layer 1 thickness is 0.015mm, and polyvinyl chloride layer 3 thickness are 0.018mm.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.
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.
