Abstract
The utility model discloses an antibacterial frozen food packaging film which comprises a multilayer co-extrusion antifreeze antibacterial film base layer. A flexible base film is arranged under the multilayer co-extrusion antifreeze antibacterial film base layer, and an antifreeze film layer is arranged on the multilayer co-extrusion antifreeze antibacterial film base layer. The antibacterial frozen food packaging film is simple in structure and excellent in antibacterial property, the flexibility of the film under freezing conditions can be guaranteed, and brittle rupture can be prevented. Compared with the prior art, the antibacterial frozen food packaging film has the advantages that the antibacterial frozen food packaging film is easy to process and does not contain any chemical compositions which can possibly contaminate foods, and accordingly food contamination can be prevented.
Description
Technical field
The utility model belongs to packaging film and manufactures field, especially relates to a kind of manufacture field of frozen-pack food-film that can be antibacterial.
Background technology
Along with social development, people's rhythm of life is more and more faster, and therefore people are increasing for the frozen-pack food demand amount of instant, and traditional frozen film does not have antibacterial effect, this just makes the shelf-life of packaged food shorter, causes food waste.Preparing the membrane material that existing antibacterial effect can apply to again freezing field is very important.Frozen film has proposed certain requirement to the performance of film, is mainly that frozen film need have under freezing conditions not embrittlement, does not paste food body and has certain elasticity.Adding of antibiotic property needs special technique.At present, prior art realizes the antibiotic property of frozen film by apply the mode of chemical preservation antimicrobial coating in polyethylene film upper and lower surface, but because its coating itself has other chemical compositions, food security is produced to certain influence, and will significantly improve the complex process degree of composite membrane adding of spraying coating process.
Utility model content
The technical problems to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and a kind of frozen-pack film with antibiotic property is provided.
The utility model solves the technical scheme that its technical problem adopts:
A kind of antibacterial Frozen Food Packaging film, comprises multi-layer co-extruded antibacterial film basic unit, and multi-layer co-extruded antibacterial film basic unit has flexible carrier film, and multi-layer co-extruded antibacterial film basic unit is provided with antifreeze rete.
Further, described multi-layer co-extruded antibacterial film basic unit is odd-level co-extrusion film, comprises in the two-layer polyolefin composite membrane of repetition and presss from both sides one deck antibacterial film structure.Described polyolefin composite membrane is to comprise that with vistanex polyethylene, low density polyethylene (LDPE), linear low density of polyethylene, polypropylene or olefin polymer are as one or more mixing in ethylene-vinyl acetate copolymer etc.Described antibacterial film is that ethylene-vinyl acetate copolymer and antibacterial plastic concentrate are as the blend such as shitosan, sodium alginate gained film masterbatch.Preferably, PP TYPE adopts 5 layers of structure, in three strata alkene composite membranes, presss from both sides two-layer antibacterial film.Preferably, the thickness of multi-layer co-extruded antibacterial film basic unit is between 0.3-0.8mm.
Further, described flexible carrier film is polyethylene/vinyl-acetate ethylene copolymer composite membrane.It is prepared as and will after polyethylene and ethylene-vinyl acetate copolymer blend, melt extrudes film forming.Preferably, wherein the mass ratio of polyethylene and ethylene-vinyl acetate copolymer between 60:40-80:20.Preferably, the thickness of flexible membrane is between 0.05-0.15mm.
Further, described antifreeze rete is thermoplastic elastomer films layer, can adopt polyolefins thermoplastic elastomer film (TPO film), polyurethanes thermoplastic elastomer films (TPU film).Preferably, select polyolefins thermoplastic elastomer film.Preferably, the thickness of antifreeze rete is between 0.1-0.4mm.
Further, in described antibacterial Frozen Food Packaging film, the combination of each layer is: first, after multi-layer co-extruded antibacterial film basic unit and flexible carrier film contact surface are applied to cold seal glue, cold seal is bonding, thereafter, and by coating hot-melt adhesive hot binding on antifreeze rete and multi-layer co-extruded antibacterial film basic unit contact-making surface.
The beneficial effects of the utility model are: the utility model has adopted multi-layer compound structure, and technique is simple.Selected each layer when antibiotic property is provided, also ensured under freezing conditions good retractility of composite membrane, the intensity that not embrittlement and tool are certain, be not easy breakage.Meanwhile, selected each layer all reaches food packaging requirement, can not exert an influence to food quality.

Detailed description of the invention
Embodiment 1
Below in conjunction with drawings and Examples, the utility model embodiment 1 is described further.
With reference to Fig. 1, a kind of antibacterial Frozen Food Packaging film, comprises multi-layer co-extruded antibacterial film basic unit 1, and multi-layer co-extruded antibacterial film basic unit has flexible carrier film 2, and multi-layer co-extruded antibacterial film basic unit is provided with antifreeze rete 3.
With reference to Fig. 2, described multi-layer co-extruded antibacterial film basic unit 1 is five tunic co-extrusion films, comprises 1-1,1-3, and tri-layers of 1-5 are polyethylene/vinyl-acetate ethylene copolymer composite membrane.Its prepare micro-by polyethylene and ethylene-vinyl acetate copolymer film and the 1-2 taking mass ratio 50:50 blend as raw material, 1-4 is two-layer is antibacterial film, its be prepared as with ethylene-vinyl acetate copolymer and sodium alginate with mass ratio 60:40 blend after the multi-layer co-extruded film being become.The thickness of multi-layer co-extruded antibacterial film basic unit is 0.5mm.
Described flexible carrier film 2 is polyolefin composite membrane, and the present embodiment adopts polyethylene/vinyl-vinyl acetate copolymer composite membrane, and in film, both mass ratioes are 70:30.The thickness of flexible carrier film is 0.08mm.
Described antifreeze rete 3 is polyolefins thermoplastic elastomer film (TPO film).The thickness of antifreeze rete 3 is 0.2mm.
Further, in described antibacterial Frozen Food Packaging film, the combination of each layer is: first, by bonding cold seal after multi-layer co-extruded antibacterial film basic unit 1 and flexible carrier film 2 contact surfaces coating cold seal glues, thereafter, by coating hot-melt adhesive hot binding on antifreeze rete 3 and multi-layer co-extruded antibacterial film basic unit 1 contact-making surface.
Above a kind of preferred embodiment of the present utility model is done to detailed introduction.Described detailed description of the invention is just for helping to understand core concept of the present utility model.It should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also belong to the protection domain of the utility model claim.
