Composite film for biological medicine packaging

Abstract

The invention discloses a composite film for biological medicine packaging, which comprises a CPP layer, an aluminum foil layer, a PET layer, a polyurethane adhesive layer and an antibacterial layer,and is characterized in that the CPP layer, the aluminum foil layer, the PET layer, the polyurethane adhesive layer and the antibacterial layer are sequentially and adjacently connected together fromtop to bottom. The packaging material has the characteristics of being simple in structure, high in high temperature resistance, good in antibacterial property, high in strength and the like, and canwell meet the requirements of biological medicine packaging.

Description

technical field [0001] The invention belongs to the field of biomedical packaging, in particular to a composite film used for biomedical packaging. Background technique [0002] Composite film is an important product in the field of pharmaceutical packaging and is widely used in packaging various dosage forms of drugs. The existing composite film for pharmaceutical packaging will be sterilized during the production process, such as disinfection with ethylene oxide or gamma rays, or High temperature disinfection, but due to the poor high temperature resistance of the existing composite film for medical packaging, the temperature of disinfection should not be too high, otherwise it will cause the composite film for medical packaging to be burned by high temperature, so that a good disinfection effect cannot be achieved, so The high temperature resistance of the existing composite film for medical packaging needs to be improved. Secondly, after the above disinfection, during t...

Problems solved by technology

[0002] Composite film is an important product in the field of pharmaceutical packaging and is widely used in packaging various dosage forms of drugs. The existing composite film for pharmaceutical packaging will be sterilized during the production process, such as disinfection with ethylene oxide or gamma rays, or High temperature disinfection, but due to the poor high temperature resistance of the existing composite film for medical packaging, the temperature of disinfection should not be too high, otherwise it will cause the composite film for medical packaging to be burned by high temperature, so that a good disinfection effect cannot be achieved, so The high temperature resistance of the existing composite film for pharmaceutical packaging needs to be improved

Secondly, after the above disinfection, during the transportation, sale and use of the composite film for pharmaceutical packaging, bacteria will still adhere to the inner or outer surface of the packaging composite film, causing pollution and possibly affecting the efficacy of the medicine. The antibacterial properties of composite films for packaging still need to be improved

Furthermore, the existing composite film for medical packaging has the disadvantage of low strength, so it will cause the composite film for medical packaging to break or be damaged, and then the medicine will be polluted, so the strength of the existing composite film for medical packaging is still low. Room for improvement
