Abstract
The utility model belongs to the field of thin film preparation and particularly relates to an antibacterial thin film. The thin film sequentially comprises a surface biaxially oriented polypropylene layer, an antibacterial layer, a high-barrier coating layer and a base biaxially oriented polypropylene layer, wherein the total thickness of the thin film is between 30 micrometers and 50 micrometers; the thickness ratio of the surface biaxially oriented polypropylene layer to the base biaxially oriented polypropylene layer is 1:(2-1):4; the upper surface and the lower surface of the high-barrier coating layer are coated with adhesion layers. The thin film disclosed by the utility model adopts a structure of arranging the antibacterial layer between the double biaxially oriented polypropylene layers, so that the antibacterial effect lasting time is long and the antibacterial thin film formed by the co-extrusion of the double biaxially oriented polypropylene layers is incapable of changing the functions and the effects of the original biaxially oriented polypropylene layers.
Description
Technical field
The utility model belongs to film preparation field, relates in particular to a kind of antibacterial film.
Background technology
Along with the concern of people to healthy and health care of body, wish to reduce in food processing chemical addition agent as far as possible.This proposes new challenge to the safety and the quality that are passed to the food storing of selling market from the processing place of production, requires the not only fresh and easily storage of food of selling.The current extensive development along with processing, transportation, storage integrated technique, the circulation of commodity expands to all over the world.Therefore the preservation of food not only needs the shelf life that remains certain, but also needs nutrition fresh.For using blister-pack food, if add antiseptic in film, can effectively suppress the growth of microorganism of food surface, and not need deepfreeze technology.So both can save the energy, also can reduce the selling cost of food.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of antibacterial film, is intended to improve the fresh-keeping cycle of food, reduces the selling cost of food.
The utility model is achieved in that a kind of antibacterial film, it is characterized in that, comprises successively top layer Biaxially oriented polypropylene layer, antibiotic layer, high-barrier coating layer and basic unit's Biaxially oriented polypropylene layer, and gross thickness is 30～50 μ m.
Further, the Thickness Ratio of described top layer Biaxially oriented polypropylene layer and basic unit's Biaxially oriented polypropylene layer is 1:2～1:4.
Further, the aspect up and down of described high-barrier coating layer scribbles adhering layer.
The utility model compared with prior art, beneficial effect is: the structure that adopts double-layer double-direction oriented polypropylene layer inner clip antibiotic layer, make the antibacterial effect time long, the antibacterial film that double-layer double-direction oriented polypropylene layer coextruded structure forms does not change function and the effect of original Biaxially oriented polypropylene layer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
In figure, 1 is that top layer Biaxially oriented polypropylene layer, 2 is that antibiotic layer, 3 is that high-barrier coating layer, 4 is basic unit's Biaxially oriented polypropylene layer.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of antibacterial film, comprises top layer Biaxially oriented polypropylene layer 1, antibiotic layer 2, high-barrier coating layer 3 and basic unit's Biaxially oriented polypropylene layer 4 successively, and gross thickness is 40 μ m.
The Thickness Ratio of top layer Biaxially oriented polypropylene layer and basic unit's Biaxially oriented polypropylene layer is 1:2.
Adopt the compound rear co-extrusion of multilayer film to process.
Be that with the difference of embodiment 1 gross thickness of film is 50 μ m.
The Thickness Ratio of top layer Biaxially oriented polypropylene layer and basic unit's Biaxially oriented polypropylene layer is 1:4.
The aspect up and down of high-barrier coating layer scribbles adhering layer.
Owing to scribbling adhering layer, make co-extrusion better effects if, be not easy layering.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
1. an antibacterial film, is characterized in that, this film comprises top layer Biaxially oriented polypropylene layer, antibiotic layer, high-barrier coating layer and basic unit's Biaxially oriented polypropylene layer successively, and gross thickness is 30～50 μ m.
