Bread and cheese packaging bag or film do not possess sterilization, antibacterial function, can only intercept extraneous bacterium, gas, steam enters the packing material sealed, only can within a period of time, keep packing material to never degenerate by physical means.And helpless from the microorganism that deposition in process of manufacture, the microorganism adhered to and packaging material are entrained in packaging for foodstuff process to packaging material, self secondary pollution problem can not be solved.
Utility model content
The purpose of this utility model is to provide a kind of self-cleaning antibacterial food package film, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of self-cleaning antibacterial food package film, packaging film is lamination layer structure, described packaging film comprises mechanical strength barrier layer, tack coat, multi-layer co-extruded antibacterial film basic unit and self-cleaning function layer, by tack coat by mechanical strength barrier layer, multi-layer co-extruded antibacterial film basic unit and self-cleaning function layer are complex as a whole, described multi-layer co-extruded antibacterial film basic unit is odd-level co-extrusion film, comprise in two layers of polyethylene/ethene one acetate ethylene copolymer composite membrane of repetition and press from both sides one deck antibacterial film structure, described self-cleaning function layer is multi-layer co-extruded structure, it comprises three layerings, three layerings are followed successively by corona layer, support sandwich layer, self-cleaning function hot sealing layer, wherein corona layer is adjacent with tack coat, described mechanical strength barrier layer is the skin of packaging film, self-cleaning function layer is the internal layer of packaging film.
As further program of the utility model: uniform nano-class antibacterial agent particle in described self-cleaning function hot sealing layer, the particle diameter of described nano-class antibacterial agent particle is 30-100nm.
As the utility model further scheme: the inner side of described mechanical strength barrier layer arranges printing ink layer.
Compared with prior art, the beneficial effects of the utility model are: the utility model is provided with self-cleaning function layer, this layer and direct food contact, the nano-class antibacterial agent particle that in self-cleaning function layer, uniform broad-spectrum high efficacy is lasting, antimicrobial particles can be gone out except microorganisms such as packaging film surface most bacterium, fungi, mould, spores; Have employed multi-layer compound structure, technique is simple, selected each layer while providing antibiotic property, also very high automatic cleaning function; The utility model can be directly used in packaged food, or is processed into various food pack, can keep itself clean under field conditions (factors), improves the security of packaging for foodstuff, extends the shelf life.
Accompanying drawing explanation
Fig. 1 is the structural representation of self-cleaning antibacterial food package film;
Fig. 2 is the schematic cross-section of multi-layer co-extruded antibacterial film basic unit in self-cleaning antibacterial food package film;
In figure: the multi-layer co-extruded antibacterial film basic unit of 1-mechanical strength carrier layer, 2-printing ink layer, 3-tack coat, 4-, 5-self-cleaning function layer, 41-polyethylene/vinyl-acetate ethylene copolymer composite membrane, 42-antibacterial film, 51-corona layer, 52-support sandwich layer, 53-self-cleaning function hot sealing layer.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-2, a kind of self-cleaning antibacterial food package film, for lamination layer structure, be followed successively by mechanical strength barrier layer 1, printing ink layer 2, tack coat 3, multi-layer co-extruded antibacterial film basic unit 4 and self-cleaning function layer 5 from outside to inside, printing ink layer 2 is printed on the medial surface of mechanical strength barrier layer 1, is complex as a whole by several structure sheaf by tack coat 3.
Described mechanical strength barrier layer 1, be the combination of one or both materials adopting the materials such as BOPP, BOPET, BOPA, VMPET, AL, the printing ink layer 2 arranged inside mechanical strength barrier layer is for printing decorative pattern.
Described adhesive linkage 3 is for polyurethane glue-line or melt extrude resin bed, and processing mode is dry laminating, extrudes compound or solvent-free compound.Because solvent-free compound has, cost is low, the advantage of no solvent residue, therefore preferentially uses solventless Laminating Technology to carry out Compound Machining.
Described multi-layer co-extruded antibacterial film basic unit 4 is five tunic co-extrusion films, comprises three-layer polyethylene/ethylene-vinyl acetate copolymer composite membrane 41, its be prepared as by polyethylene and ethylene-vinyl acetate copolymer with mass ratio 50: 50 blended formed by raw material film; And two-layer antibacterial film 42, it is prepared as with ethylene-vinyl acetate copolymer and sodium alginate with the blended rear multi-layer co-extruded formed film of mass ratio 60: 40.The thickness of multi-layer co-extruded antibacterial film basic unit 4 is 0.5mm.
Self-cleaning function layer 5 is multi-layer co-extruded structure, it comprises three layerings, three layerings are followed successively by corona layer 51, support sandwich layer 52, self-cleaning function hot sealing layer 53, wherein corona layer 51 is adjacent with polyethylene/vinyl-acetate ethylene copolymer composite membrane 41, self-cleaning function hot sealing layer 53 and packaging direct food contact.Corona layer 51 is blending resin layer or the PP resin bed of LDPE, LLDPE, and the surface tension after sided corona treatment is greater than 38Mn/M, has good adhesive property.Support one or both blends that sandwich layer 52 is the high-crystallinity copolymers such as LDPE, LLDPE, HDPE or PP, wherein bimodal HDPE has good processability, PP should select acrylic resin copolymer, for increasing the compatibility of itself and PE interface, can the LLDPE resin of blended 20-35% in PP resin.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
