Description
Technical field
The utility model is related to fresh-keeping field of material technology, more particularly to a kind of food materials packing sheet.
Background technology
With the improvement of people ' s living standards, people are additional except packaging, smell, color, shape etc. except being concerned about commodity
Beyond value, the health of oneself and household is become more concerned with, also increasingly worry preservative film easy breed bacteria in daily life
Potential danger, it is a kind of with natural antibacterial preservative film it is therefore necessary to provide so that preservative film has anti-microbial property, suppress fine
Fiber products surface bacterial growth, keeps preservative film surface itself clean.
At present, using based on being thickeied usually using anti-bacterial fibre on anti-biotic material and arranging, its mainly in general fibre or
The method that a small amount of antiseptic is added in the dressing liquid of non-weaving cloth is obtained, and antiseptic to be a class can kill or suppress bacterium,
The harmful microbe functional material such as virus, through searching document, the antiseptic applied in general fibre or non-weaving cloth at present
The big series of inorganic antiseptic, organic antibacterial agent and natural antibacterial agent three is broadly divided into by structure.Wherein：
1）Organic antibacterial agent is including quaternary ammonium salt, imidazoles, pyridines, organic metal class etc., although sterilization speed is fast, resists
Bacterium effect is significant, but in the presence of drug resistance is also easy to produce, heat endurance is poor, and Durability of antimicrobial effect is short, and toxicity is big to wait not enough, so as to give fiber
And its product brings new healthy hidden danger.
2）Compared with organic antibacterial agent, inorganic antibacterial collection have have a safety feature, heat decomposition temperature is high, good stability, anti-
Bacterium ability is strong and the features such as lasting antibacterial, research at present it is at most most extensive.
Inorganic antiseptic is typically to be made up of antibacterial components and carrier, the metal ion with antibacterial activity have silver, chromium,
Cobalt, nickel, copper, zinc and iron plasma, consider that silver ion is best jointly from security and antibiotic property.But silver ion antimicrobial agent is direct
Using silver ion as antiseptic, there is following defect：First, silver ion is easily reduced and is changed into black in simple substance, influence silver
Application of the ion antibacterial agent in light color article, anti-tarnishing ability is poor.Secondly, silver oxide precipitates are easily generated in alkaline environment,
Sustained release performance is poor, influences Durability of antimicrobial effect.Again, when silver ion meets the article or environment of chlorion, easily generation silver chlorate sinks
Form sediment and lose activity, salt resistant character is poor.Finally, silver carrying amount is relatively low, complex process, and required auxiliary agent species is various.
As can be seen here, silver ion antimicrobial agent is mainly the method by physical absorption or ion exchange, will be with antibacterial energy
The metal or metal ion of power be fixed on the surface of certain carrier for example zeolite, activated carbon, phosphate, silicate, dissolubility glass,
The material being made on the carriers such as porous metals.Patent of invention such as Publication No. CN102599164B provides a kind of nano lamellar
The preparation method of silver-amino acid complex antiseptic is carried, silver salt, amino acid, hydromassage that are compared 1 first:1:2.7 are mixed
Close, 30min, 50 DEG C of stirring in water bath 15min is stirred at room temperature, mixing speed is 8000r/min, obtained solution, secondly in 50 DEG C of water
Montmorillonite is added in bath under mixing speed 8000r/min, agitation and filtration obtains feed liquid, and separation of solid and liquid is carried out after, is placed in room
The lower drying of temperature, obtains fluffy ivory shape anti-bacterial powders, and it has preferable discoloration-resisting, improves the sustained release of antiseptic
Performance and salt tolerance.
However, the inorganic antiseptic based on the metal ions such as silver, zinc, though have antimicrobial efficiency high, strong excellent of heat resistance
Point, but either inorganic antiseptic or organic antibacterial agent, it is that based on chemical material addition, can sometimes produce one
Fixed adverse consequences, such as chemical industry are sterilized to differentiate weak for killing property of strain System, can cause to manslaughter and cause other beneficial bacteriums to be killed, and
And certain treatment pollution is had in processing procedure after use.Additionally, chemical addition agent has certain bad shadow to human body
Ring, long-term or regular contact may cause irreversible injury, long-term use and touch to contain the metals such as silver, zinc to human body
The product of ion can be adversely affected to the liver of human body, meanwhile, expensive, environmental protection shortcoming.These defects limit silver
Ion antibacterial agent application in the product.Based on previous reasons, natural antibacterial agent comes into existence as the situation requires, compared with foregoing antiseptic, day
Right antiseptic is extracted from plant, animal or biology, and its wide material sources, low cost are high with safety non-toxic, antimicrobial efficiency,
It is heat-resist, drug resistance is not likely to produce, there is environment friendly, therefore its application and research increasingly by the weight of people
Depending on.Such as notification number for the patent of invention of CN103800928B discloses antibacterial deodorant, it is mainly one kind with the white leaf rattan of plant
The alkaloid in source and the antiseptic deodorising product that new cryptolepine analog is main effective ingredient, including weak acid regulation
Agent, dipotassium hydrogen phosphate, solubilizer, metal-chelating salt, cyclodextrin, active component, essence, can eliminate peculiar smell in cloth products, while
Effectively in removal cloth products or the bacterium that is attached in cloth products and virus, and safely and effectively, fundamentally remove due to bacterium
The stink for causing.
The content of the invention
The purpose of this utility model is exactly to provide a kind of food materials packing sheet, in order to realize above-mentioned target, the utility model
