Abstract
The invention discloses a cold stamping formed composite hard sheet for packaging medicines. The hard sheet comprises a polyamide layer, a maleic anhydride modified polyethylene layer, an acrylic acid modified polyethylene layer, an aluminum foil layer, a dry-laminate glue layer and a polyvinyl chloride layer which are arranged in turn. By the maleic anhydride modified polyethylene layer and the acrylic acid modified polyethylene layer which are extruded in a co-extrusion mode, the aluminum foil layer and the polyamide layer to which the maleic anhydride modified polyethylene layer and the acrylic acid modified polyethylene layer are attached have higher peel strength, the whole extrusion layer is flexible and high in toughness and has high tensile strength and elongation at rupture, and a product can be effectively prevented from having problems of aluminum rupture, layer separation and the like in the cold stamping process.
Description
Technical field
The invention belongs to the field of medicine packing, be specifically related to a kind of medicine and pack with the cold stamping shaped composite hard sheet of using.
Background technology
Existing medicine packing is used cold stamping shaped composite hard sheet, is mostly to adopt the production of twice dry type combination process, and its basic structure is aramid layer, does multiple glue layer, aluminium foil layer, does multiple glue layer, polyvinyl chloride layer.This kind composite hard sheet production cost height, and the aluminium that is in use occurred splits and problem such as absciss layer.
Summary of the invention
For overcoming the total problem of prior art, the object of the present invention is to provide a kind of production cost low, effectively avoid aluminium to split and pack with the cold stamping shaped composite hard sheet of using with the medicine of absciss layer phenomenon.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of medicine is packed with the cold stamping shaped composite hard sheet of using, and it comprises the aramid layer that sets gradually, maleic anhydride modified polyethylene layer, acrylic acid modified polyethylene layer, aluminium foil layer, does multiple glue layer, polyvinyl chloride layer.
A kind of method for preparing above-mentioned medicine packing with cold stamping shaped usefulness composite hard sheet, with the modified polyethylene particle of described maleic anhydride modified polyethylene layer and acrylic acid modified polyethylene layer by the compound mode of coextrusion, described aramid layer and aluminium foil layer are combined with each other, and then pass through described doing in the compound mode of dry type and answer glue layer, described aluminium foil layer and described polyvinyl chloride layer are combined with each other.
Compared with prior art the present invention has the following advantages:
From result of use, maleic anhydride modified polyethylene layer and the acrylic acid modified polyethylene extruding layer extruded by the coextrusion mode, not only have with accompanying separately aluminium foil layer, aramid layer and have higher peel strength, and whole extruding layer softness, toughness are strong, have high hot strength and elongation at break, can prevent effectively that the aluminium that product may occur from splitting and problems such as absciss layer in the cold stamping process.And,, has greater advantage on the cost than existing common process by the product that preparation technology of the present invention produces.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the layer structure schematic diagram of multi-layer co-extruded cell culture container bag packaging film of the present invention.
Number in the figure explanation: 1, aramid layer, 2, maleic anhydride modified polyethylene layer, 3, acrylic acid modified polyethylene layer, 4, aluminium foil layer, 5, do multiple glue layer, 6, polyvinyl chloride layer.
The specific embodiment
Below in conjunction with drawings and Examples to technical scheme further instruction of the present invention.
Referring to shown in Figure 1, a kind of medicine is packed with the cold stamping shaped composite hard sheet of using, comprise the aramid layer 1, aluminium foil layer 4, the polyvinyl chloride layer 6 that set gradually, be provided with one between described aluminium foil layer 4 and the described polyvinyl chloride layer 6 and do multiple glue layer 5, be provided with a maleic anhydride modified polyethylene layer 2 and an acrylic acid modified polyethylene layer 3 between described aramid layer 1 and the described aluminium foil layer 4.
Medicine of the present invention is packed with the cold stamping shaped composite hard sheet preparation method that uses, may further comprise the steps: with the modified polyethylene particle of described maleic anhydride modified polyethylene layer 2 and acrylic acid modified polyethylene layer 3 by the compound mode of coextrusion, described aramid layer 1 and aluminium foil layer 4 are combined with each other, and then pass through described doing in the compound mode of dry type and answer glue layer 5, described aluminium foil layer 4 is combined with each other with described polyvinyl chloride layer 6.
The foregoing description just is to allow the one of ordinary skilled in the art can understand content of the present invention and enforcement according to this for technical conceive of the present invention and characteristics being described, its objective is, can not limit protection scope of the present invention with this.The variation or the modification of every equivalence that the essence of content has been done according to the present invention all should be encompassed in protection scope of the present invention.
