Abstract
The invention relates to a PE (polyethylene) self-sealing bag containing a glass-supported silver ion antibacterial agent, which contains 0.001 to 1.5 percent of glass-supported silver ion antibacterial agent on the basis of a common PE (polyethylene) self-sealing bag, or further contains one or more of 0.5 to 6 percent of antifoggant and 1 to 6 percent of degradable master batch. The PE in the PE (polyethylene) self-sealing bag is one of high-density polyethylene, low-density polyethylene or linear low-density polyethylene or is formed by mixing the high-density polyethylene, low-density polyethylene and linear low-density polyethylene according to a certain ratio. The manufacturing process is to mix and granulate the PE and the glass-supported silver ion antibacterial agent in a single-screw or double-screw extruder to obtain antibacterial master batch; and according to the formula, blowing or casting a film in an extruder, making a bag and thus, obtaining the antibacterial self-sealing bag. The finished product has remarkable antibacterial effect, can be used for a long time without changing color. The bag has a remarkable inhibiting and killing effect on bacteria, particularly Escherichia coli and staphylococcus aureus.
Description
Technical field
The present invention relates to contain a kind of valve bag of antiseptic-germicide, a kind of specifically valve bag that contains the glass carrier silver ion antimicrobial agent contains this antiseptic-germicide, long, the film color nondiscoloration of the antibiotic good and timeliness of valve bag.Valve bag also can claim other titles such as airtight bag, closely knit bag, hereinafter to be referred as valve bag.
Technical background
All be common valve bag on the domestic market at present, do not contain antiseptic-germicide, do not contain the glass carrier silver ion antimicrobial agent especially.Developed countries has entered the antibiotic epoch in the eighties in last century.Domestic antibiotic in recent years industry development just begins, but technology is very different, as: antibacterial effect is not good, easy to change or the like, and problem has much room for improvement.Along with growth in the living standard, people are more and more higher to standard of living and quality, environmental requirement, to the hygiene and health conditional request more a step improve, people are also very high to the requirement of antimicrobial product.
The antibiotic valve bag that the present invention relates to has excellent inhibition or killing action to intestinal bacteria, gold-coloured staphylococci, and inhibition or killing rate reach more than 99.99%.Antiseptic-germicide of the present invention is to belong to the glass carrier silver ion antimicrobial agent, retrieves a large amount of patent documentations, and still the report of glass carrier silver ion antimicrobial agent is found to add in common polythene valve bag the inside in the end.
Summary of the invention
The present invention contains the antibiotic valve bag with glass carrier silver ion antimicrobial agent, and the antiseptic-germicide in the described antibiotic valve bag is a kind of the silver ion antimicrobial agent of glass as carrier.Described antibiotic valve bag antibacterial mechanisms is that under the condition of humidity, the present invention slowly discharges the small amount of silver ion.Because bacterium surface has negative charge, the silver ions that therefore has positive charge is attracted to bacterium surface, and then destroys its electrolyte balance, causes bacterium because cell walls is impaired and dead.
Also having a kind of viewpoint is that silver ions enters bacterium inside, with cell enzyme reaction and the chemical combination of bacterium, has suppressed the activity of cellular enzymes and the breeding regeneration of bacterium, reaches the effect of kill bacteria.In polyethylene, add inorganic antiseptic,, can produce muddy sense usually, so but the base material of silver ion antimicrobial agent of the present invention is the transparency that glass can be kept transparent resin by the control specific refractory power because of polyethylene is a transparent material.This is its advantage, and antibiotic valve bag just of the present invention has surprising nondiscoloration effect.After so-called variable color just was meant that general film adds common inorganic antiseptic, As time goes on the color of film became little Huang or brown problem,
The self-styled main points of glass carrier silver-ion antibiotic bag of the present invention are to contain and have the glass carrier silver ion antimicrobial agent that (from Ishizuka Glass, commodity are by name
), select below following, the preferred 5um of its particle diameter 50um.Described glass carrier silver-ion antibiotic valve bag composition is polyethylene, glass carrier silver ion antimicrobial agent, or further contains in antifogging agent, the degradable master batch one or more.Respectively polyethylene more than 86.5%, glass carrier silver ion antimicrobial agent 0.001%-1.5%, antifogging agent 0.5%-6%, degradable master batch 1%-6%.
At first glass carrier silver ion antimicrobial agent and part polyethylene are passed through single screw rod or twin screw plastics extruder extruding pelletization by a certain percentage, become the antibacterial polyethylene master batch, it is than classifying glass carrier silver ion antimicrobial agent 1%-35%, polyethylene 65%-99% as, preferred glass carrier silver ion antimicrobial agent 20%, polyethylene 80%, more preferably glass carrier silver ion antimicrobial agent 10%, polyethylene 90%.Polyethylene can be high density polyethylene(HDPE), new LDPE (film grade) or linear low density polyethylene, preferably with the polyethylene of above-mentioned antibiotic valve bag homogeneity.
Above-mentioned single screw rod or twin screw plastics extruder, preferred twin screw plastics extruder, more preferably low-temperature and high-speed twin screw plastics extruder.
Above-mentioned antibacterial matrices and polyethylene in proportion in agitator the inside blend, are added the material that mixes in the plastics extruder and to melt extrude, blown film, bag, to prepare antibiotic valve bag or curtain coating, bag, prepare antibiotic valve bag.Blown film, curtain coating can be selected the single or multiple lift co-extrusion, and internal layer and skin or internal layer contain antiseptic-germicide when multi-layer co-extruded, and the middle layer can contain also can not contain antiseptic-germicide.When multi-layer co-extruded, the part by weight in ectonexine and middle layer is at 0.1%-99.9%:99.9%-0.1%.Antibiotic valve bag sealing position can be one or one or more bone bar, concavo-convex button, or clip chain.Antibiotic valve bag can be split type or integral type, the bag section of split type is phalanges bar, concavo-convex button, clip chain part and valve bag is that heat-sealing is integral, integral type be that phalanges bar, concavo-convex button, clip chain and valve bag bag section are extruded by molding machine together and formed.Bone bar, concavo-convex button, clip chain can be of the same colour or polychromes.
