Abstract
The invention discloses a medicinal full-insulation transparent composite hard sheet. The medicinal full-insulation transparent composite hard sheet comprises a first PVC layer, an ACLAR layer and a second PVC layer, and also comprises an EVOH coextrusion film, wherein the first PVC layer, the EVOH coextrusion film, the ACLAR layer and the second PVC layer are sequentially composited together. The medicinal full-insulation transparent composite hard sheet of the invention is still transparent from the use effect after compositing several layers of transparent films, has an extremely high insulation performance to water vapor and oxygen, has a symmetrical product structure, and can effectively improve phenomena of warping and the like possibly appearing in the use process; and internal and external sides of the product are heat-sealable PVC films, so the medicinal full-insulation transparent composite hard sheet is very adapted to use habits in the market.
Description
Technical field
The invention belongs to the medicine composite material for packaging, be applied to medicine blister package field, the concrete transparent composite hard sheet of a kind of medicinal full obstruct that relates to.
Background technology
Raising along with China's economic high speed development and people's living standard; Demand to instant food such as microwave food, leisure food and frozen food will constantly increase; This will directly drive the demand of relevant food packing, and Chinese food and package packing machine industry will be kept positive growth a segment length from now in the time.Estimate that the Eleventh Five-Year Plan period the gross output value of China packaging industry is expected to reach 4,500 hundred million yuans, and keeps average annual 7% growth rate.From 2011 to 2015, the gross output value was expected to break through 6,000 hundred million yuan, and annual average speedup maintains 16% level approximately.With product classification, Chinese wrapper goods output to 2015 year can reach 3,600 ten thousand tons, 9,460,000 tons of plastic packing products, 4,910,000 tons in mental package goods, 1,550 ten thousand tons in glass packaging goods, 1,200,000 covers of package packing machine.Estimate that following recycling economy will become the main pattern of packaging industry development, the useless resource recycling of packing and will realize that industrialization, environmentally friendly packing material will obtain to develop energetically and develop, pack basic industries and also will accelerate development.
Drug packing material is meant that being used to make packing container, packing and decorating, packages printing, packed and transported etc. satisfies the employed material of packing of product requirement; It promptly comprises main packaging material such as metal, plastics, glass, pottery, paper, bamboo basis, wild mushroom class, natural fiber, chemical fibre, composite, comprises auxiliary material such as coating, adhesive, strapping, decoration, printing material again.
The classification of drug packing material: strap, strap, plastic baling band, plastic packing belt twines film, and PE twines film, the multiple packaging material of PE stretched film or the like; Need meet following performance as the one of which:
1, certain mechanical performance
Packaging material should be able to be protected product effectively. therefore should have certain intensity, toughness and elasticity etc., to adapt to pressure, impact. and the influence of static(al) such as vibration and kinetic factor.
2, separating performance
According to the demands of different to the packing of product, packaging material reply moisture, steam, gas, light, aroma, peculiar smell, heat etc. have certain stopping
3, good security performance
In the existing drug packing material product, be mostly the composite hard sheet structure, comprise: PVC, PVC/PVDC, PVC/PE, infrastructure products such as PVC/ACLAR.Through use finding, existing these composites are in the shortcoming that often only water vapour or oxygen is had single barrier property.
Summary of the invention
For overcoming the problems of the prior art, the object of the present invention is to provide the transparent composite hard sheet of a kind of medicinal full obstruct, this composite hard sheet all has high barrier property to steam and oxygen.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the present invention has adopted following technical scheme:
The transparent composite hard sheet of a kind of medicinal full obstruct comprises a PVC layer, ACLAR layer and the 2nd PVC layer, and it also comprises an EVOH co-extrusion rete, and a said PVC layer, EVOH co-extrusion rete, ACLAR layer and the 2nd PVC layer are combined with each other successively.
Compared with prior art the present invention has the following advantages:
See from result of use; Which floor hyaline membrane is through after compound, and whole structure is still transparent, and steam and oxygen are all had high barrier property; Product structure is more symmetrical; Can effectively improve the phenomenons such as warpage that in use possibly occur, and the interior outside of product is all heat sealable PVC film, adapts to very much the use habit in existing market.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the structural representation of embodiments of the invention.
Label declaration among the figure: 1, a PVC layer, 2, EVOH co-extrusion rete, 3, the ACLAR layer, the 4, the 2nd PVC layer.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment technical scheme of the present invention is further explained.
Referring to shown in Figure 1; The transparent composite hard sheet of a kind of medicinal full obstruct; Comprise a PVC layer 1, ACLAR layer 3 and the 2nd PVC layer 4, it also comprises an EVOH co-extrusion rete 2, and a said PVC layer 1, EVOH co-extrusion rete 2, ACLAR layer 3 and the 2nd PVC layer 4 are combined with each other successively.
Further, the transparent composite hard sheet of medicinal full obstruct of the present invention forms through three dry type produced with combination.
In the foregoing description, a described PVC layer 1 and the 2nd PVC layer 4 all are that polyvinyl chloride layer is a kind of polymeric material of vinyl, and its material is a kind of amorphism material; Described EVOH co-extrusion rete 2 is a kind of high barrier material layer for the ethylene/vinyl alcohol copolymer layer; Described ACLAR layer 3 is a kind of polytrifluorochloroethylene thin layers with outstanding moisture barrier property and chemical stability.
The foregoing description just is to let the one of ordinary skilled in the art can understand content of the present invention and enforcement according to this in order technical conceive of the present invention and characteristics to be described, to be 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.
