Abstract
The utility model provides a medicinal suppository complex film and belongs to the technical field of medicinal packing materials. The problem that a traditional medicinal suppository complex film is poor in safety is solved by the medicinal suppository complex film provided by the utility model. The medicinal suppository complex film comprises a polyvinyl film. The upper surface of the polyvinyl film is provided with a flax fiber layer; the lower surface of the polyvinyl film is provided with a two-way stretch nylon layer; the outer side of the two-way stretch nylon layer is provided with an aluminum foil layer; three alcohol-waterborne polyurethane modified polyacrylate adhesive layers are respectively arranged between the polyvinyl film and the flax fiber layer, between the polyvinyl film and the two-way stretch nylon layer and between the two-way stretch nylon layer and the aluminum foil layer; a heat-seal adhesive layer is coated to the lower surface of the aluminum foil layer; a meshed layer is coated to the outer side of the heat-seal adhesive layer. The medicinal suppository complex film has the advantages of being high in safety, free of toxin, environmentally friendly and good in adhesivity.
Description
Technical field
The utility model belongs to pharmaceutical pack material technology field, particularly a kind of Medical suppository composite membrane.
Background technology
The wrapping composite membrane of medicine has multiple requirement, as barrier property (steam penetrating capacity), oxygen transit dose, peel strength, heat sealing strength etc.Existing composite membrane, particularly Medical suppository composite membrane exists defect in barrier property and oxygen transit dose performance, simultaneously, toluene or ethyl acetate solvent borne polyurethane hot setting adhesive that the adhesive first adopting is non-Environmental Safety, when producing PET/AL/PE drug and food composite packing film, just used so the non-Environmental Safety adhesive of this class, to production environment, cause poisonous toluene or the pollution of ethyl acetate solvent gas discharge and inflammable and explosive potential safety hazard, also made the sanitary toxicology of composite membrane product itself be affected.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of safe, asepsis environment-protecting and the good Medical suppository composite membrane of adhibit quality.
The purpose of this utility model can realize by following technical proposal: a kind of Medical suppository composite membrane, it is characterized in that, comprise polyethylene based film, at the upper surface of polyethylene based film, be provided with flax fiber layer, at the lower surface of polyethylene based film, be provided with biaxial tension nylon layer, in biaxial tension nylon layer outside, be provided with aluminium foil layer, described polyethylene based film and flax fiber layer, polyethylene based film and biaxial tension nylon layer, between biaxial tension nylon layer and aluminium foil layer, be provided with alcohol-water based polyurethane modified polyacrylate adhesive layer, aluminium foil layer lower surface is coated with heat-sealing glue-line, in heat-sealing glue-line outside, be coated with plinthitic horizon.
Compared with prior art, the utlity model has following advantage:
1, employing has stronger boiling resistance alcohol-water based polyurethane modified polyacrylate adhesive, replace original non-Environmental Safety toluene or ethyl acetate solvent borne polyurethane hot setting adhesive, polyester/aluminium/polyvinyl medicine composite film for foods package is carried out to bonding modification, during laminating production, the discharge of drying is nontoxic nonflammable alcohol-water mixing gas, not only thoroughly overcome the shortcoming of existing non-environment-friendly adhesive, kept again the Integrated using performance that this drug and food composite packing film is good simultaneously, thereby promoted well the production technology quality grade of this compound soft packing material product, obtained good environment protection modification effect.
2, there is good hot melt, and in the process of hot melt, can guarantee the requirement of surface smoothness, in the process of being convenient to pack, seal, guarantee the aesthetics after packing; Because its barrier property has also obtained certain lifting, can prevent medicine humidity simultaneously; It is stable that oxygen transit dose keeps, and makes medicine not oxidizable.
3, at aluminium foil layer lower surface, be coated with heat-sealing glue-line, in heat-sealing glue-line outside, be coated with plinthitic horizon, because heat-sealing glue-line surface is burnishing surface, when boning with bubble-cap, adhesion strength is little, passes through plinthitic horizon, can strengthen adhesion strength, make to seal glue-line firmly bubble-cap be bonded on bubble-cap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, polyethylene based film; 2, flax fiber layer; 3, biaxial tension nylon layer; 4, aluminium foil layer; 5, heat-sealing glue-line; 6, plinthitic horizon; 7, alcohol-water based polyurethane modified polyacrylate adhesive layer.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this Medical suppository composite membrane, comprise polyethylene based film 1, at the upper surface of polyethylene based film 1, be provided with flax fiber layer 2, at the lower surface of polyethylene based film 1, be provided with biaxial tension nylon layer 3, in biaxial tension nylon layer 3 outside, be provided with aluminium foil layer 4, polyethylene based film 1 and flax fiber layer 2, polyethylene based film 1 and biaxial tension nylon layer 3, between biaxial tension nylon layer 3 and aluminium foil layer 4, be provided with alcohol-water based polyurethane modified polyacrylate adhesive layer 7, aluminium foil layer 4 lower surfaces are coated with heat-sealing glue-line 5, in heat-sealing glue-line 5 outsides, be coated with plinthitic horizon 6.
Employing has stronger boiling resistance alcohol-water based polyurethane modified polyacrylate adhesive, replace original non-Environmental Safety toluene or ethyl acetate solvent borne polyurethane hot setting adhesive, polyester/aluminium/polyvinyl medicine composite film for foods package is carried out to bonding modification, during laminating production, the discharge of drying is nontoxic nonflammable alcohol-water mixing gas, not only thoroughly overcome the shortcoming of existing non-environment-friendly adhesive, kept again the Integrated using performance that this drug and food composite packing film is good simultaneously, thereby promoted well the production technology quality grade of this compound soft packing material product, obtained good environment protection modification effect.
There is good hot melt, and in the process of hot melt, can guarantee the requirement of surface smoothness, in the process of being convenient to pack, seal, guarantee the aesthetics after packing; Because its barrier property has also obtained certain lifting, can prevent medicine humidity simultaneously; It is stable that oxygen transit dose keeps, and makes medicine not oxidizable.
At aluminium foil layer 4 lower surfaces, be coated with heat-sealing glue-line 5, in heat-sealing glue-line 5 outsides, be coated with plinthitic horizon 6, because heat-sealing glue-line 5 surfaces are burnishing surface, when boning with bubble-cap, adhesion strength is little, by plinthitic horizon 6, can strengthen adhesion strength, make to seal glue-line 5 firmly bubble-cap be bonded on bubble-cap.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
