Description

Antimicrobial Quick Kill Film Technical field:
The technical field of this invention is related to medical, public healthcare products and health care facilities.
Technical issue:
Nowadays, given increasing trend of infections, there is an urgent need to antibacterial agents and films. For example, about 2 million people in the United States suffer from illnesses associated with nosocomial infections, of which around 900,000 people die each year.
In recent years, common additives such as ceramic nanoparticles, metal nanoparticles, silver nanoparticles, iron oxide nanoparticles, zinc oxide nanoparticles, titanium dioxide, magnesium oxide, and copper oxide are used to prepare antimicrobial films and coatings.
Antimicrobial coatings and films available on the market have a killing time over 24 hours.
Therefore, they are not able to use in infected areas because they cannot kill bacteria and germs immediately.
Antimicrobial additives such as ethanol, isopropanol, chlorhexidine, propyl alcohol, benzalkonium chloride, peracetic acid, hydrogen peroxide, Didecyldimethylammonium chloride, Polyhexamethylene Biguanide Hydrochloride, chlorhexidine gluconate, alkyl dimethyl benzyl ammonium chloride, Sodium hypochlorite, iodine, 70% alcohol, glutaraldehyde, Sodium iodide and chloramine T, or a combination of these additives have immediate effect (under 24 hours) on bacteria. Usually these additives are used in gels and sprays and antiseptic tissues and so far these additives have not been used to produce antimicrobial films with self-antiseptics surface.
Prior arts:
= WO 2014/001541 is an invention related to an antimicrobial package suitable for containing materials which are susceptible to microbial growth or spoilage. In particular, the invention relates to an antimicrobial package for food and drink products = WO 2006/000032 refers to an antimicrobial polymeric package in which an antimicrobial additive has been used. This invention can be used in food packaging. In this invention, the polymeric materials are ethylene vinyl acetate (EVA), low-density polyethylene (PE), polyethylene glycol oil (PEG) and volatile antimicrobial oils.
Previous inventions dealt with food and fruit packaging, aimed at preventing entry of essential nutrients for bacterial growth, which ultimately leads to prolonging life span of the package content. It should be noted that market's available films with antimicrobial properties do not have the ability to remove bacteria instantaneously and immediately. They are used only for food and fruit packaging. Up to this time, an anti-microbial film with the aim of killing bacteria in a fraction of second has not been produced.
2 Description of the invention:
The purpose of the invention is preventing the spread of bacteria and infectious disease by preparing a polymeric film with immediate bactericidal properties. In this invention, an antimicrobial agent is stored in a carrier which can regulate the antimicrobial agent release rate from an hour to several months. It should be noted that the antimicrobial properties of the film produced in this invention are customizable. This product can be used in the health-care facilities as smart coatings to prevent the transmission of microbes/ infections to every individual by direct and indirect contact. Moreover, it can be used as a smart covers in public areas and public transportation.
In the present invention, polymers such as ethylene-based polymers (high-density polyethylene (HDPE) , low density polyethylene (LDPE), linear low density polyethylene (LLDPE) ), polypropylene (PP), polyamide (PA), polystyrene (PS), Polyethylene terephthalate (PET), polyvinyl chloride (PVC), Ethylene vinyl acetate (EVA) (8%, 18%, 28%, 38%) and natural polymers such as starch, poly lactic acid (PLA), natural rubber (NR) and Acrylonitrile butadiene rubber (NBR), or a combination of one or more polymers by percentages 5% to 50% can be used for the preparation of the antimicrobial films.
All films contain one or more carriers that hold antimicrobial agents, polymer's-compatible oils such as polyethylene glycol (PEG) with a molecular weight varies from 300 g /
mole to 10,000,000 g! mole, Polypropylene glycol (PPG), Dioctyl phthalate (DOP), diisodecyl phthalate (DIDP), diisononyl phthalate (DINP) with a composition of 1% to 30%.
Moreover, antimicrobial agents such as ethanol, isopropanol, chlorhexidine, propyl alcohol, benzalkonium chloride, peracetic acid, hydrogen peroxide, Didecyldimethylammonium chloride, Polyhexamethylene Biguanide Hydrochloride, chlorhexidine gluconate, alkyl dimethyl benzyl ammonium chloride, Sodium hypochlorite, iodine, 70% alcohol, glutaraldehyde, Sodium iodide and chloramine T, with the composition of 0.01% to 20% can be used. Based on the type of the polymer oil and antimicrobial agents, the effective film performance time range can be tuned.
In support of this claim, the polymers that were used to prepare the films for this invention were LLDPE / EVA/ Oil with the volume fraction of (70%/28%/2%), respectively. The combination of PEG 400 and 4000 with the volume fraction of 50%/50% were used as an antimicrobial carrier and benzalkonium chloride was used as antimicrobial agent with the volume fraction of 0.13%.
It should be noted that the films prepared by combining different percentages of polymers LLDPE / EVA / Oil ( 90%-60%/10%-40%/ 1%-20%) and PEG as carrier material alone with a molecular mass of 300 g /Mole up to 10,000g / mole with a composition of 1% -30% of PEG or a combination of them with different molecular weights ranging from 300 g!
mole to 10,000 g!
mole with a composition of 1% -30% and benzalkonium chloride as an antimicrobial agent with a composition of 0.01% 20% is within the scope of this invention.
3 After preparing different specimens, antimicrobial activity of the films was investigated. E.coli bacteria with the concentration of 106 x 1.5 CFU / ml was prepared. 100 pl of fluid was contacted for 24 hours before inoculation with the sample. After culturing the medium for 8 hours, according to the optical density method, each sample series was evaluated using three biological replications at 600 nm wavelength. The results of microbial tests taken at different time intervals from films prepared with different composition percentages showed that 98.9% of bacteria were killed.
In addition, Performance repeatability of the films was tested by the Luminometer device with the general swab. The dirty object was rubbed several times with specific intervals on the armchair covered with the antimicrobial film and on the armchair without the antimicrobial film.
The results show that the covered-armchair is in the sterile range after rubbing the dirty object.
To prepare the samples, PEG and benzalkonium chloride were first mixed together in a dry blender, then EVA was added and then LLDPE was added to the final blend in a dry blender.
Finally, the final blend was processed in a twin screw extruder. Finally, a film blowing machine was used to make smart films. The temperature range was applied to all the machines has been set between 135-140 C.
