Abstract
The invention discloses a polyamide-aluminum cold-stamping formed medicine packaging composite film. The composite film is characterized by sequentially comprising a polyamide layer, an aluminum foil layer and a heat seal coating layer, wherein a composite adhesive layer is arranged between the polyamide layer and the aluminum foil layer. Most of conventional packaging films adopt a twice dry-type compounding technology, so that in a cold stamping process, an aluminum foil layer is easy to break; and in a wet or strong-light environment, medicines are prone to oxidative deterioration because of a delamination phenomenon. The composite film is higher in isolation property to water steam, oxygen and light rays; the polyamide layer is made from PA6, is high in water absorption property and wet absorption property and can be recycled; and the heat seal coating layer is made of a double-component adhesive, has a non-drying property and a hot smelting property, and is high in bonding strength and suitable for packaging of health protection foods, medicines and other products with high requirements on high density and wet resistance.
Description
Technical field
The present invention relates to a kind of medicine composite packing film, specifically refer to the cold stamping shaped medicine composite packing film of a kind of polyamide-aluminium.
Background technology
In recent years, along with China's medical skill fast development, medical system progressively perfect accelerated the expansion of pharmaceutical industry thus, and how reasonable packing, transportation and storage medicine seem and be even more important.Mostly existing medicine composite packing film is to adopt twice dry type combination process, and the aluminium foil layer breakage problem appears in program complexity easily in the cold stamping process, and this kind medicine composite packing film production cost is higher, and the scope of application is little.When running into wet environments such as containing more steam, oxygen, ultraviolet ray, particularly during southern damp and hot weather, make and cause unnecessary economic loss by the medicine oxidation deterioration thereby the medicine packing is prone to the absciss layer phenomenon.
Summary of the invention
The invention reside in provides a kind of polyamide-aluminium cold stamping shaped medicine composite packing film, is prone to aluminium foil layer fracture or the defective of absciss layer to solve existing medicine composite packing film, reaches the purpose of protection medicine.
Purpose of the present invention is achieved through the following technical solutions:
The cold stamping shaped medicine composite packing film of a kind of polyamide-aluminium comprises the aramid layer, aluminium foil layer and the heat-seal coating that set gradually up and down, is provided with composite layer between described aramid layer and the aluminium foil layer.With the aramid layer that PA6 makes, can intercept the factor that extraneous steam, oxygen, light etc. may cause the medicine qualitative change; Aluminium foil itself just has good plasticity and high gas barrier, but its shortcoming is obvious equally, add man-hour easily wrinkling, crack, curl and to rupture because the tension force that bears causes aluminium foil often.Therefore, aramid layer and aluminium foil layer are combined with each other, heat-seal coating is bonding by the cold stamping mode with whole composite membrane and backing material, the histocompatbility that the easy modification of polyamide obtains and easy to process, be easy to moulding, have certain submissive or rigidity, provide protection in the time of curling for aluminium foil, prevent its fracture; Aluminium foil and polyamide all have iris action to steam, oxygen etc., have avoided effectively causing the influence of the factor of medicine qualitative change, thereby have reached the purpose of protecting medicine.
Further, the cold stamping shaped medicine composite packing film of described polyamide-aluminium thickness is 20-25um, when satisfying higher transparency and steam, oxygen, light had higher barrier property, can also save material.
Further, the material of described aramid layer is PA6, and water imbibition and hygroscopicity are better and can recycle.
Further, the material of described heat-seal coating is the 101-polyurethane adhesive, has non-drying and hot melt, has higher bonding strength.
Further, described composite layer is alcohol-water based polyurethane modified polyacrylate adhesive, and when compound production, the mixing gas to producing alcohol and water can not pollute environment.
The present invention compared with prior art has the following advantages and beneficial effect:
The cold stamping shaped medicine composite packing film of a kind of polyamide-aluminium of 1 the present invention, because polyamide has water imbibition and hygroscopicity preferably, aluminium foil has higher barrier property to steam, oxygen, light, can be widely used in high density, moistureproof intercept the packings of product such as the health food of having relatively high expectations, medicine.
The cold stamping shaped medicine composite packing film of a kind of polyamide-aluminium of 2 the present invention, the material of heat-seal coating is the 101-polyurethane adhesive, has non-drying and hot melt, has higher bonding strength, energy and backing material are compound, are applicable to blister packages such as capsule, tablet.
The cold stamping shaped medicine composite packing film of a kind of polyamide-aluminium of 3 the present invention, because its combination process is easy, PA6 can be recycled, can effectively reduce production costs, composite layer is alcohol-water based polyurethane modified polyacrylate adhesive, when compound production, to the mixing gas that produces alcohol and water, can not pollute suitable promoting the use of to environment.
Description of drawings
Fig. 1 is layer structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is further described:
Embodiment 1
As shown in Figure 1, the cold stamping shaped medicine composite packing film of a kind of polyamide-aluminium comprises the aramid layer 1, aluminium foil layer 3 and the heat-seal coating 4 that set gradually, is provided with composite layer 2 between 3 layers on described aramid layer 1 and the aluminium foil; The aramid layer made from PA6 1 intercepts the factor that extraneous steam, oxygen, light etc. may cause the medicine qualitative change as protective layer.
As shown in Figure 1, aramid layer 1 is combined with each other with aluminium foil layer 3, and heat-seal coating 4 is the 101-polyurethane adhesive, and whole composite membrane and backing material is bonding by the cold stamping mode, also applicable to blister packages such as capsule, tablets.
Embodiment 3
As shown in Figure 1, composite membrane thickness is 20-25um, when satisfying higher transparency and steam, oxygen, light had higher barrier property, can also save material.
