According to the oxygen-absorbing high-barrier film for medicinal package, a high-oxygen-barrier material and an oxygen deoxidation adsorption material are compounded and bonded together, the oxygen in a package bag can be adsorbed by adopting the package material having an oxygen adsorption function after medicine package, accordingly a two-way medicine oxygen adsorption and barrier function is achieved, the medicine packaging safety is improved, and a guarantee period is prolonged.
Description
Technical field
The present invention relates to packaging material field, especially a kind of oxygen absorption type high-barrier pharmaceutical pack film.
Background technology
Medicine is a kind of special commodity, due to by illumination, humidity, microorganism pollution isoperimetric collarette in the process of circulation
The impact in border is easy to decomposed metamorphic, it is necessary to could keep the effect of medicine from suitable packaging after medicine machine-shaping
The stability of medicine, can be improved, delay medicine to go bad, ensure the drug safety of broad masses of the people, therefore pharmaceutical packing quilt
It is known as " second life " of medicine.Qualified Key works Drug packing should possess sealing, stable, light, attractive in appearance, specification is suitable, packaging
Mark specification, reasonable, clear the features such as, also should meet drug flow, storage, application each link requirement.Some Drugs are to oxygen
Gas is very sensitive, but reaches preferable packaging effect from the best packaging material of oxygen barrier also difficulty, because the low dose of bag of medicine
Dress is not suitable for being vacuum-packed, and is also not suitable for deoxidant packing, is not suitable for the deoxidation packing technique such as nitrogen-filled packaging, also just cannot remove
Enclose the partial oxidation in packaging bag in pack environment, oxygen accounts for the 21% of AIR Proportional.
So it is now desired to a kind of energy efficiently blocking oxygen, making Medicine Package Bag interior energy keep anaerobic state for a long time
Pharmaceutical pack film.
Content of the invention
The technical problem to be solved is for above-mentioned deficiency of the prior art, provides a kind of oxygen absorption type high
Intercept pharmaceutical pack film.By using a kind of packaging material with oxygen uptake function, packaging bag can be adsorbed after it packs medicine
Interior oxygen is so as to keep anaerobic state for a long time in bag, thus the Key works Drug packing difficult problem to some oxygen sensitives can be solved.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of oxygen absorption type high-barrier pharmaceutical pack film,
Including the biaxially oriented laminated polyester film setting gradually from outside to inside, the first adhesive for polyurethane layer, aluminium foil layer, the second polyurethane
Adhesive layer, polyolefin corona layer, deoxidation adsorption layer and heat-sealable layer.
Preferably, described deoxidation adsorption layer is made from the deoxidation adsorbent with oxygen removing adsorption function, its
As the deoxidation adsorption function layer of packaging material, there is a certain amount of oxygen removing adsorption function, can actively adsorb after packaging
Oxygen component in removing packaging bag.
Preferably, the thickness of described biaxially oriented laminated polyester film is 12-15 μm, and it has extraordinary stretching
Intensity, indeformable in process, when the thickness of described biaxially oriented laminated polyester film is less than 12 μm, its tensile strength mistake
Low, easily it is deformed in process, affect product quality；When the thickness of described biaxially oriented laminated polyester film is higher than 15
μm when, its tensile strength too high it is difficult to processing, affect production efficiency.
Preferably, the first described adhesive for polyurethane layer sticks agent by two-component polyurethane adhesive and makes, and its thickness is 2-4
μm, provide film interlayer good cementability, when the thickness of the first described adhesive for polyurethane layer is less than 2 μm, its cementability
Too low, make the sealing between biaxially oriented laminated polyester film and aluminium foil layer inadequate；When the first described adhesive for polyurethane layer
Thickness be more than 4 μm when, the two-component polyurethane adhesive in the first described adhesive for polyurethane layer stick agent easily outflow, impact produce
Quality.
Preferably, described aluminium foil layer is 6.5-12 μm of aluminum foil material for thickness, provides the high barrier of composite membrane
Can, when the thickness of described aluminium foil layer is less than 6.5 μm, its barrier property is poor, and oxygen and vapor readily penetrate through described aluminium foil
Layer；When the thickness of described aluminium foil layer is more than 12 μm, it is easily reduced described aluminium foil layer and described biaxially oriented polyester film
Sealing between layer and described polyolefin corona layer.
Preferably, the second described adhesive for polyurethane layer sticks agent by two-component polyurethane adhesive and makes, and its thickness is 2-4
μm, provide film interlayer good cementability, when the thickness of the first described adhesive for polyurethane layer is less than 2 μm, its cementability
Too low, make the sealing between polyolefin corona layer and aluminium foil layer inadequate；Thickness when the first described adhesive for polyurethane layer
During more than 4 μm, the two-component polyurethane adhesive in the first described adhesive for polyurethane layer sticks agent and easily outflows, and affects product matter
Amount.
Preferably, described polyolefin corona layer is made up of the polyolefine material after processing through surface corona, itself and institute
State adhesive for polyurethane layer and there is good cementability.
Preferably, described heat-sealable layer is made up of polyolefine material, has good heat sealing performance.
Preferably, described polyolefin corona layer, deoxidation adsorption layer and heat-sealable layer are three-layer co-extruded film processed, it
Between there is heat fused viscosity.
Beneficial effects of the present invention: oxygen absorption type high-barrier pharmaceutical pack film disclosed by the invention is by high oxygen barrier material and removing
The Material cladding of adsorption of oxygen bonds together, by using the packaging material with oxygen uptake function, energy after it packs medicine
Oxygen in absorption packaging bag, it is achieved thereby that medicine deoxygenation, the two-way function intercepting, improves Key works Drug packing security, prolongs
Grow the shelf-life.
