Embodiment 1 to 3

[0039] Below are three examples for determining the minimum effective content of a metal-based antimicrobial agent with three different levels at the same thickness of the surface layer (top film layer or bottom film layer). Different film layers are made of different PE formulations. ISO 22196 test results show a minimum effective content of 0.4%.

[0040]

[0041] Note: Single side refers to adding metal-based antimicrobial agent to the top film layer or bottom film layer.

Embodiment 4 to 6

[0043] The following are three examples to determine the antibacterial efficacy of antibacterial plastic film samples with different configurations. The different film layers are made of different polyethylene (PE) formulations. ISO 22196 test results show:

[0044] (a) Double-sided antimicrobial films can be fabricated by loading antimicrobial agents on top and bottom film layers.

[0045] (b) The antimicrobial efficacy was not affected by the change in the thickness of the surface layer of the antimicrobial film.

[0046] (c) The antibacterial efficacy is not affected by the change of the number of layers and the total thickness of the multilayer film structure of the antibacterial film.

[0047]

[0048] Note: Single side refers to adding metal-based antimicrobial agent to the top film layer or bottom film layer.

[0049] Double-sided refers to the addition of metal-based antimicrobial agents to both the top film layer and the bottom film layer.

Embodiment 7 to 9

[0051] Below are three examples of determining the antimicrobial efficacy of three different antimicrobial agents at the same levels. The different film layers are made of different polyethylene (PE) formulations. ISO 22196 test results showed that three different metal-based antimicrobials were effective.

[0052]

[0053]

[0054] Note: Single side refers to adding metal-based antimicrobial agent to the top film layer or bottom film layer.

[0055] Use the ISO 22196 (2007) standard test procedure to measure the antibacterial activity on the surface of the antibacterial plastic film of the present invention, find that the antibacterial plastic film of the above-mentioned multilayer structure has a high antibacterial effect during the 24-hour test, which is required for the working hours of disposable medical products That's enough time to cover. In addition, the added cost for loading metal-based antimicrobials has been minimized because: (a) the amount of metal-based...

Abstract

The invention discloses an antibacterial plastic film and an application thereof. The antibacterial plastic film is a multilayer film structure, the multilayer film structure at least comprises a topfilm layer and a bottom film layer, and the top film layer and / or the bottom film layer contains a metal-based antibacterial agent. The antibacterial plastic film can be used in the field of medical and health, such as nursing pads, equipment covers, surgical drapes, surgical towels, partition curtains, shower curtains, garbage bags and various cover sheets. The antibacterial plastic film has a good antibacterial effect, and can reduce hospital-acquired infection when applied to the technical field of medical and health.

Description

technical field [0001] The invention relates to a film, in particular to an antibacterial plastic film and its application. Background technique [0002] A major concern of hospitals around the world is the high incidence of hospital-acquired infections. According to the World Health Organization, one in ten patients may develop a bacterial or fungal infection during their hospital stay. In the United States, the average cost of treating each infected patient is about $15,000. In addition, an increasing number of bacterial-associated infections are being identified worldwide that cannot be treated with commonly used antibiotics. Therefore, most hospitals have committed to washing and disinfecting hands by requiring all hospital staff to wash and disinfect their hands before and after touching patients and hospital furniture and equipment (including beds, chairs, armrests, examination tables, couches, temperature probes, ultrasonic sensors, etc.) In order to reduce the HAI...
