Abstract
The invention discloses an environment-friendly high-barrier-property PP/COC/PP composite sheet and a manufacturing method of the environment-friendly high-barrier-property PP/COC/PP composite sheet. The composite sheet comprises a COC layer and PP layers arranged on the two sides of the COC layer respectively. The environment-friendly high-barrier-property PP/COC/PP composite sheet meets the requirement for the barrier property of a medicine packaging material, is good in shock strength, improves the shock resistance of the packaging material and guarantees the quality of the packaging material.
Description
Technical field
The present invention relates to drug packages Material Field, particularly, relate to a kind of environmental protection high-barrier PP/COC/PP composite sheet and preparation method.
Background technology
In various pharmaceutical packing material, because PVDC (Vingon) tool is to effective barrier of aqueous vapor, oxygen, smell and grease and be easy to heat sealability, PVC/PVDC high-barrier composite sheet is widely used, but in this composite sheet, employ PVC sheet, as everyone knows, the stability of PVC to heat, light, oxygen is poor, and long-time use can discharge objectionable impurities, cause the pollution of medicine, harmful.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of safety non-toxic and PP/COC/PP composite sheet of environmental protection high-barrier and preparation method thereof.
The present invention's adopted technical scheme that solves the problem is:
A kind of composite sheet, comprises COC layer, and is located at the PP layer of described COC layer both sides respectively.
The present inventor adopts the COC(cycloolefin analog copolymer with performances such as excellent water vapor barrier property, ambient atmos barrier and fragrance protectiveness), replace existing high-barrier PVDC sheet material, as the interlayer of packing, realize the requirement of packaging high-barrier.Again at the PP layer of the both sides of described COC layer difference compound one deck safety non-toxic, as pharmaceutical packing, both met the high barrier of Key works Drug packing, gone back environment-protecting asepsis simultaneously.
Further, described composite sheet is adopt the method for hot melt compound to obtain.
The present invention also provides a kind of preparation method of above-mentioned composite sheet, is specially, and by stacked in order to PP layer, COC layer and PP layer, and is carrying out hot melt compound under 180-190 DEG C of hot melting temperature, can obtain.
To sum up, the invention has the beneficial effects as follows: PP/COC/PP three-layer composite structure of the present invention meets the requirement of drug packing material to barrier, and also there is obviously good impact strength, improve the impact resistance of packing, ensure that the quality of packing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the composite sheet shown in present pre-ferred embodiments;
Mark and corresponding parts title in accompanying drawing: composite sheet 100, PP layer 10, COC layer 20.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Composite sheet given by the present invention adopts following standard method to carry out performance testing:
Oxygen transit dose: measure according to gas permeation quantitative determination method (YBB0082003) first method, during test, PP aspect is to oxygen low pressure side;
Steam penetrating capacity: measure according to the cup type method of steam penetrating capacity determination method (YBB00092003) first method, during test, PP is towards the low side of humidity, and test temperature is (23 ± 0.6) DEG C, and relative humidity is (90 ± 2) %;
Impact strength: adopt ASTM D256A standard method to test, breach type is A.
Embodiment 1
Refer to Fig. 1, the composite sheet 100 shown in present pre-ferred embodiments, comprises COC layer 20, and is located at the PP layer 10 of described COC layer both sides respectively, and the composite sheet 100 shown in the present embodiment can be used as the bubble-cap of Key works Drug packing, high-barrier and safety non-toxic.Stacked according to the order of PP layer 10, COC layer 20 and PP layer 10, and under 180 DEG C of hot melting temperatures, carry out hot melt compound can obtain above-mentioned composite sheet 100.
PP/COC/PP composite sheet given by the present embodiment 1 is carried out to the performance testing of oxygen transit dose, steam penetrating capacity, impact strength, and by outcome record in following table 1.
Comparative example 1
There is provided a kind of composite sheet, comprise COC layer and be located at the PP layer of described COC layer side, this composite sheet adopts the method identical with embodiment 1 to obtain.PP/COC composite sheet given by this comparative example 1 is carried out to the performance testing of oxygen transit dose, steam penetrating capacity, impact strength, and by outcome record in following table 1.
Table 1
| Oxygen transit dose cm 3/（m 2·24h·0.1MPa） | Steam penetrating capacity g/(m 2·24h） | Impact strength kJ/m 2 | |
| Embodiment 1 | 12 | 1.7 | 60 |
| Comparative example 1 | 13 | 1.7 | 31 |
As Key works Drug packing composite material, require below demand fulfillment: oxygen transit dose is no more than 20 cm
3/ (m
224h0.1MPa), steam penetrating capacity is no more than 2.5 g/(m
224h).
From in upper table 1, can find out, embodiment 1 and the composite sheet shown in comparative example 1 all meet as the requirement to barrier required for Key works Drug packing.
Compared by embodiment 1 and comparative example 1, can find out, the impact strength of three-layer composite structure PP/COC/PP composite sheet of the present invention is obviously good compared with the impact strength of the PP/COC two layer composite structure shown in comparative example 1, about improves nearly one times, improves significantly.
In sum, PP/COC/PP three-layer composite structure of the present invention meets the requirement of drug packing material to barrier, and also has obviously good impact strength, improves the impact resistance of packing, ensure that the quality of packing.
As mentioned above, the present invention can be realized preferably.
The above; it is only preferred embodiment of the present invention; not any pro forma restriction is done to the present invention; according to technical spirit of the present invention; within the spirit and principles in the present invention; the any simple amendment that above embodiment is done, equivalently replace and improve, within the protection domain all still belonging to technical solution of the present invention.
