Medicine aluminum foil description

The heat-insulating coating 5 is uniformly coated with heat-insulating paint. For details of the heat-insulating paint, please refer to the barrier-type heat-insulating paint mentioned in http://baike.baidu.com/link? Type heat-insulating coating is a kind of coating that achieves heat insulation through the high thermal resistance of the coating itself. After being fully dried and cured, the thermal conductivity of the material is very small after drying and forming a film, so the coating has a certain ability to slow down the transfer of heat flow. ability.

UV bonding layer 4 is formed by uniform coating of UV coating, specifically can refer to application number and be 201520348879.9 patent UV coating not only has good adhesion performance, can thermal insulation coating 5 and luminous layer 3 tightly fixedly connected, UV coating is a kind of ultraviolet curable coating, which has good resistance to ultraviolet rays. It will be cured after being irradiated by ultraviolet rays, and the fixing effect will be strengthened. Denaturation plays a role in protecting the quality of the tablet.

Luminescent layer 3 comprises strontium aluminate luminescent powder layer, strontium aluminate luminescent powder layer can refer to application number as mentioned in 201520351342.8, strontium aluminate luminescent powder layer mainly comprises strontium aluminate luminescent powder, strontium aluminate luminescent powder Powder is a kind of long afterglow material. Under the excitation of light source, it can emit visible light at night, so that objects can be seen in the dark at night, and the aluminum foil for pharmaceutical packaging can emit a certain amount of light, so that patients can be seen in the dark. Medicines can be found very quickly, and since the intensity of visible light emitted by the luminous layer 3 is not very high, it will not affect the patient's rest.

Printing layer 2 is formed by spraying ink, and ink is an existing material, so it will not be repeated here.

Transparent self-cleaning layer 1 is evenly coated by transparent self-cleaning coating, specifically can refer to the nanometer self-cleaning coating mentioned in http://www.bmlink.com/zswhua/news/526997.html, nanometer Self-cleaning paint is based on the principle of bionics, using the dual synergy of nano-materials, the lotus leaf amphiphobic mechanism, low surface tension, high adhesion, high hardness and toughness of the paint film, excellent self-cleaning function, strong anti-corrosion Dust and anti-dirty adhesion ability, excellent hydrophobicity, miraculous effect on dust mist, easy to clean dirt performance. And it has good gloss and color retention functions, strong anti-ultraviolet ability, high light transmittance, and the extremely low surface tension of nano-materials makes it have strong hydrophobic and oil-resistant capabilities; it reduces the surface contact area of dust by 90%. Incomparably superior self-cleaning properties, dust and water roll off the surface of the nano-self-cleaning coating like a lotus leaf without leaving water marks, which can effectively extend the cleaning time, the cleaning interval is long and the cleaning is particularly easy. The surface contact area of the nano self-cleaning coating is greatly reduced, so it has incomparably superior self-cleaning characteristics; water rolls off the surface of the object like a lotus leaf without leaving water marks, which can effectively prolong the cleaning time.

Aluminum foil layer 6 is provided with macromolecule film layer 7 with respect to the other side that thermal barrier coating 5 is set, can effectively reduce the transmission rate of water vapor and oxygen by the setting of macromolecular film layer 7, prevents medicine from getting wet , oxidation and deterioration. The polymer film layer 7 is made of PET material. For details, refer to the application number 201520348324.4. The polymer film layer 7 can be made of high-barrier and low-elution polymer materials such as PETJeflon. The molecular film layer 7 can effectively reduce the permeability of water vapor and oxygen, and prevent the medicine from being dampened, oxidized and deteriorated.

The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the utility model all belong to the scope of protection of the utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
