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 medicines. Existing composite films 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

Embodiment Construction

[0019] The present invention will be further described below with reference to the accompanying drawings and examples. The embodiments of the present invention include but are not limited to the following examples.

[0020] Embodiment: in order to realize the above object, the technical scheme adopted in the present invention is as follows:

[0021] like figure 1 As shown, the present invention provides a composite film for biomedical packaging, CPP layer 1, aluminum foil layer 2, PET layer 3, polyurethane adhesive layer 4 and antibacterial layer 5, CPP layer 1, aluminum foil layer 2, PET layer 3. The polyurethane adhesive layer 4 and the antibacterial layer 5 are adjacently connected together from top to bottom.

[0022] The present invention further provides that: the antibacterial layer 5 is a nano-silver layer, and its thickness is between 0.5 microns and 0.9 microns.

[0023] The present invention further provides that: the thickness of the aluminum foil layer 2 is betw...

Abstract

The invention discloses a composite film for biomedical 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: a CPP layer, an aluminum foil layer, a PET layer, and a polyurethane adhesive The agent layer and the antibacterial layer are successively connected together from top to bottom. The invention has the characteristics of simple structure, strong high temperature resistance, good antibacterial property and high strength, and can well meet the requirements of biomedical packaging.

Description

technical field [0001] The invention belongs to the field of biological medicine packaging, in particular to a composite film for biological medicine packaging. Background technique [0002] The composite film is an important product in the field of pharmaceutical packaging and is widely used in the packaging of various dosage forms of pharmaceuticals. The existing composite film for pharmaceutical packaging will be sterilized during the production process, such as sterilized 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 disinfection temperature cannot be too high, otherwise the composite film for medical packaging will be burned out by high temperature, which will not achieve a good disinfection effect, so The high temperature resistance of the existing composite films for pharmaceutical packaging still needs to be improved. Secondly, after the a...
