Abstract
The invention provides an antibacterial composite plastic packing membrane and the making process thereof. And it comprises heat sealing layer, middle layer, and outer layer, where the composition of the heat sealing layer contains: LLDPE 5-40 parts, LDPE 10-35parts, MPE 15-35parts, and antibacterial agent 0.5-5 parts,the composition of the middle layer contains MPE 3-5parts, LDPE 15-25parts, LLDPE 55-70parts, antibacterial agent 0.2-3parts,the composition of the outer layer contains MPE 3-13parts, LDPE 15-35parts and LLDPE 45-65parts. And it carefully chooses antibacterial agent which has high-efficiency broad-spectrum property, is safe and nontoxic to human body, and has good heat resistance and succeeds in combining the antibacterial agent with PE membrane which has common physical and mechanical properties and makes the antibacterial agent uniformly distributed on the surface of the PE membrane, thus improving antibacterial function of the membrane and the surface polarity and hydrophily of the membrane, so as to make the membrane have good antistatic property.
Description
(1) technical field
The present invention relates to packing technique, be specifically related to a kind of various plastic composite packaging films such as medicine, dairy products, food, health that can be used for.
(2) background technology
Plastic package material removed and to satisfy client's quality 21 century, outside the requirement that time of delivery, service etc. improve day by day, also must develop to directions such as the recycling economy of environmental protection, high in technological content, sustainable development, safety.
Use the enterprise of packing in order to guarantee the requirements for quality of content at present, extend the shelf life, the mode of the general sterilization of adopting, mainly contain following several sterilizing methods: the first method high temperature sterilization, the advantage of this method is to kill the bacterium of food or packing in the short time, shortcoming is to destroy the nutritional labeling in the food and increase productive costs, and another shortcoming is that the product in some field can't be sterilized with high temperature sterilization, as products such as medicine, milk powder, quick-frozen food, amenitiess; Can second method hydrogen peroxide sterilization generally be that the content of liquid adopts this method, but can leaves residuals after the hydrogen peroxide sterilization, the healthy problem that to bring hidden danger be troubling always and pay close attention to that give the people; The third method is the ultraviolet sterilization method, and the advantage of this method is less to the degree of tortuosity of content and packing, but sterilization is not thorough; The method that also has multiple sterilization in addition, but its all in various degree have a shortcoming.
(3) summary of the invention
The object of the present invention is to provide a kind of safety non-toxic, antibacterial effect is lasting, stable performance, and good heat resistance, polarity and wetting ability are strong, have the antibiotic composite plastic packing film and the manufacture craft thereof of antistatic property.
Product slate of the present invention is: it comprises hot sealing layer, interlayer and outer trilamellar membrane, the composition weight portion of hot sealing layer is LLDPE5 part-40 part: 15 parts-35 parts of 10 parts-35 parts of LDPE: MPE: 0.5 part-5 parts of antiseptics, the composition weight portion of interlayer is 55 parts-70 parts of 15 parts-25 parts of 3 parts-5 parts of MPE: LDPE: LLDPE: 0.2 part-3 parts of antiseptics, outer field composition weight portion are 45 parts-65 parts of 15 parts-35 parts of 3 parts-13 parts of MPE: LDPE: LLDPE.
Technical scheme of the present invention is:
I, at first open clean air system, start Modern Transducer Technology and computing machine and Long-distance Control, mechanics of communication, and clean area is utilized the ultraviolet disinfection technology sterilization treatment that carries out disinfection, make blown film unit and operating environment reach 100,000 grade standards;
II, nitrogen or air filtration are purified, make nitrogen or air after the purification reach hundred grade standards;
III, join in the different purification puddle mixers after the polyethylene particle of various performances distributed by the properties of product requirement and carry out full and uniform stirring;
IV, the polyethylene particle with various performances after will stirring join in the different hoppers on request;
V, make various polyethylene particles from the hopper of isolating, enter extruder, add antiseptic simultaneously, allow antiseptic and polyethylene particle stir through closed conduit;
VI, startup blown film unit make above-mentioned polyethylene particle carry film behind extruder barrel indirect heating and melting, inflate the back one-tenth tubular film that froths;
VII, tubular film is lowered the temperature after the rolling, making flat tube does not have the mycoderm finished product, carries out air secondary once more in equipment rolling place and purifies, and mention the highest at the exposed region of product air pressure;
VIII, with antibiotic PE film through printing, compound, cut or the bag operation is made antibiotic composite plastic film.
The present invention also has some technical characterictics like this:
1, is equipped with independently cleaning treatment system in described each hopper.
The present invention adopts Polymer to make up antibiotic up-to-date technology, by selectedly have high efficiency, broad spectrum activity, to the antiseptic of human body safety non-toxic, good heat resistance to reach the fungi-proof purpose.The present invention uses three-layer co-extruded blown film specialized equipment to produce, select LLDPE (linear polyethylene): LDPE (low density polyethylene (LDPE)): MPE (metallocene PE) for use at hot sealing layer: antiseptic, both had low-temperature heat-sealing performance, barrier, mechanical strength height, had antibacterial action simultaneously again; Interlayer at film then selects diaphaneity for use, (PE) particle of carrying high strength polyethylene, thereby the institute that makes the antibacterial film of production both have functional membrane has outside physical property and the mechanical characteristics, has the fungi-proof performance simultaneously again.Because antiseptic is easy to be distributed in the surface of film, improved the antibacterial functions of film on the one hand, also improved the polarity and the wetting ability on the surface of film on the other hand, thereby made film also have anlistatig performance.
The know-why of the antibiotic composite plastic film of the present invention is, cell membrane or the cell membrane of general bacterium and fungi all contain electronegative protein, have broad-spectrum sterilization and add inorganic silver ion antimicrobial agent, it can be adsorbed onto on the microbial cell, influences normal breathing of cell and metabolic function; Or cause cell membrane (wall) to break, and content flows out, thus kill microorganisms reaches the fungi-proof purpose.Because charge environment is the basis of bacterium, conk and breeding, lack this environment, it is dead that bacterium and fungi are all wanted.Inorganic silver ion antimicrobial agent is to link to each other with substrate macromolecule material by chemical bond, has not only further guaranteed the safety of using, and has guaranteed the long-lasting of antibacterial effect.Therefore, this technology has that outstanding high-efficiency broad spectrum is antibiotic, safety non-toxic, antibacterial effect be lasting, stable.
The present invention has antibiotic, the safety non-toxic of broad spectrum activity, and antibacterial effect is lasting, stable performance, features such as high obstructing performance such as resistance oxygen, resistance vapour.
