Abstract
The invention aims to provide a low-loss metallized film. The low-loss metallized film comprises a base film, a pure aluminum clad layer positioned above the base film, and a thickening area positioned above the pure aluminum clad layer, wherein the thickness of the thickening area is gradually thinned from left to right; a zinc-aluminum composite coating is coated on the thickening area; the width of the thickening area is not smaller than one fourth of the width of the pure aluminum clad layer. The thickening area is arranged to be the gradually thinned zinc-aluminum composite coating, so that the oxidation resistance of product can be improved, and the product loss is reduced; moreover, the thickness of the thickening area is gradually thinned, so that the processing is simple, and the production technology can be effectively simplified.
Description
Technical field
The present invention relates to metallized film, be specifically related to a kind of low-loss metallized film.
Background technology
Traditional metallized film adopts fine aluminium or zinc-aluminium composite processing mostly, because two kinds of products respectively have pluses and minuses, for merging two kinds of product oxidation resistances by force and the little advantage of loss, occur that a kind of thickened area is that zinc-aluminium is compound, and the product that general area is fine aluminium, structure as shown in Figure 1, the thickening of Jin Wei edge, thickened area, edge thickening is limited to the improvement of oxidation resistance and loss, still existing product can not be met required, therefore need further to improve the oxidation resistance of metal oxide film, thereby reduce product loss.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of low-loss metallized film, be set to the thin zinc-aluminium composite deposite of gradual change by thickened area, can improve the oxidation resistance of product, reduce product loss, and due to the thickness of thickened area for gradually by thick attenuation, make processing simple, can effectively simplify production technology.
In order to address the above problem, the invention provides a kind of low-loss metallized film, comprise basement membrane, be positioned at the fine aluminium coating of basement membrane top and be positioned at the thickened area of fine aluminium coating top, the thickness of described thickened area is attenuation gradually from left to right, and described thickened area is the zinc-aluminium composite deposite plating.The width of described thickened area must not be less than 1/4th of fine aluminium coating width.
Further improvement of the present invention is: the width of described thickened area is 1/2nd of fine aluminium coating width.
Further improvement of the present invention is: the left end of described thickened area is provided with strengthens district, strengthens the thickness in district identical with the high order end of thickened area, and the overall width in described thickened area and reinforcement district must not be less than 1/4th of fine aluminium coating width.
Further improvement of the present invention is: described reinforcement district is zinc-aluminium composite deposite.
Further improvement of the present invention is: described metallized film is two-sided metal-coated membrane, and two sides film plating layer structure is identical, and direction is in the same way or oppositely.Double-sided coating structure, can effectively improve the oxidation resistance of product, reduces product loss, extends the service life of product.
Beneficial effect of the present invention: be set to the thin zinc-aluminium composite deposite of gradual change by thickened area, can improve the oxidation resistance of product, reduce product loss, and because the thickness of thickened area is for gradually by thick attenuation, make processing simple, can effectively simplify production technology; Be provided with thickened area strengthening the left end in district, to film edge further strengthen, thereby improve the oxidation resistance of film integral.
The present invention is simple in structure, can effectively improve the oxidation resistance of product, reduces the loss of product, and simplifies production technology.
