Abstract
The utility model discloses a complex film for medicine packaging, including the PVC substrate layer, the one side of PVC substrate layer is provided with dampproofing heat -seal layer, is provided with antibiotic layer on dampproofing heat -seal layer, and the another side of PVC substrate layer is provided with the resistant layer of waiting. The utility model discloses have bacterinertness, dampproofing heat sealability, weatherability, intensity is big and toughness characteristic such as strong, and through crowded shaping altogether, the influence of nos adhesive, safety ring guarantor.
Description
Technical field
The utility model relates to a kind of composite membrane, and more particularly, it relates to a kind of medical packaging composite membrane.
Background technology
Medical packaging material industry is as new industry, and development in recent years is rapid, and it is with high content of technology, and quality requirement is strict, and medicine directly can contact with packaging, and therefore, medical packaging material must be nontoxic, and does not affect health.
Composite membrane is a kind of packaging material being widely used in medical packaging field, its base material mainly adopts PVC material or aluminium foil, the transit dose of PVC to oxygen and aqueous vapor is large, and the effect of heat insulation of aluminium foil is not good, cracky, all can affect drug quality, therefore, other materials adhesive substrate can be adopted when preparing composite membrane, make composite membrane have more performances.
But existing medical packaging composite membrane intensity is lower, comprehensive not to the protection of medicine, easily damaged and drug quality is affected, reduce the quality guarantee period of medicament phase, and function is comparatively single, jointly can not embody more kinds of function; Meanwhile, in composite membrane production process, adopt adhesive, containing a small amount of residual solvent, quality and the health of medicine can be affected in the composite film packaging finished product produced.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of medical packaging composite membrane, has the characteristics such as the large and toughness of antibiotic property, moistureproof heat sealability, weatherability, intensity is strong, and passes through coextrusion mold, adhesive-free affects, safety and environmental protection.
For achieving the above object, the utility model provides following technical scheme:
A kind of medical packaging composite membrane, comprise PVC base layer, the one side of PVC base layer is provided with anti humid heat sealing, anti humid heat sealing is provided with antibiotic layer, the another side of PVC base layer is provided with weathering layer, and namely level is from inside to outside respectively: antibiotic layer, anti humid heat sealing, PVC base layer and weathering layer.
The utility model is set to further: antibiotic layer is evenly applied by Nano Silver and forms.
The utility model is set to further: anti humid heat sealing is comprised BOPP layer and PE layer and formed by BOPP layer and PE layer co-extrusion.
The utility model is set to further: weathering layer is TPU film layer.
The utility model is set to further: TPU layer and PVC base layer, BOPP layer and PE layer are coextrusion mold.
Advantage of the present utility model can be summarized as:
Medical packaging composite membrane level is from inside to outside respectively: antibiotic layer, anti humid heat sealing, PVC base layer and weathering layer.Nano Silver is evenly applied the antibiotic layer forming innermost layer, have strong suppression and killing action to tens of kinds of pathogenic microorganisms such as Escherichia coli, gonococcus, chlamydia trachomatises, and drug resistance can not be produced; BOPP film has good air-tightness, mechanical strength and transparency, and PE film has waterproof and dampproof property, is had by the composite membrane formed and highly seal and moistureproof advantage after BOPP film and PE film co-extrusion; PVC film layer has heat resistance, also has good toughness; TPU film intensity is high, tearing strength is high, elasticity is high and low temperature resistant, its withstand temperature scope is-110 DEG C-120 DEG C, namely TPU film layer not only has weatherability, also there is good mechanical strength, be placed in the outermost layer of composite membrane, not only can ensure drug quality under the environment that pole cold-peace is very hot unaffected, and larger external force can be born, make composite membrane not easily damaged.TPU layer and PVC base layer, BOPP layer and PE layer are coextrusion mold, medical packaging composite membrane the is had characteristic such as the large and toughness of moistureproof heat sealability, weatherability, intensity is strong, ensure drug quality, and medical packaging composite membrane passes through coextrusion mold, adhesive-free affects, safety and environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1, antibiotic layer; 2, anti humid heat sealing; 21, BOPP layer; 22, PE layer; 3, PVC base layer; 4, weathering layer.
Detailed description of the invention
With reference to Fig. 1, the utility model is described further.
With reference to figure 1, a kind of medical packaging composite membrane, comprise PVC base layer 3, the one side of PVC base layer 3 is provided with anti humid heat sealing 2, anti humid heat sealing is provided with antibiotic layer, the another side of PVC base layer 3 is provided with weathering layer, and namely composite membrane level is from inside to outside respectively: antibiotic layer 1, anti humid heat sealing 2, PVC base layer 3 and weathering layer 4.Wherein, antibiotic layer 1 is evenly applied by Nano Silver and forms, and weathering layer 4 is TPU film layer, and TPU layer and PVC base layer 3, BOPP layer 21 and PE layer 22 are coextrusion mold.
Nano Silver is evenly applied the antibiotic layer 1 forming innermost layer, have strong suppression and killing action to tens of kinds of pathogenic microorganisms such as Escherichia coli, gonococcus, chlamydia trachomatises, and drug resistance can not be produced; BOPP film has good air-tightness, mechanical strength and transparency, and PE film has waterproof and dampproof property, is had by the composite membrane formed and highly seal and moistureproof advantage after BOPP film and PE film co-extrusion; PVC film has heat resistance, also has good toughness; TPU film intensity is high, tearing strength is high, elasticity is high and low temperature resistant, its withstand temperature scope is-110 DEG C-120 DEG C, namely TPU film layer not only has weatherability, also there is good mechanical strength, be placed in the outermost layer of composite membrane, not only can ensure drug quality under the environment that pole cold-peace is very hot unaffected, and larger external force can be born, make composite membrane not easily damaged.TPU layer and PVC base layer 3, BOPP layer 21 and PE layer 22 are coextrusion mold, medical packaging composite membrane the is had characteristic such as the large and toughness of moistureproof heat sealability, weatherability, intensity is strong, ensure drug quality, and medical packaging composite membrane passes through coextrusion mold, adhesive-free affects, safety and environmental protection.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
