Abstract
The utility model relates to a polypropylene base film, in particular to a bidirectional drawing polypropylene base film for printing. The utility model mainly aims at solving the technical problems that the base film of the prior art can only be used for low-class printing with low requirement, inaccurate chromatic printing or chromatic printing failure always occur when the base film is used for certain high-class printing, patterns are not vivid, the effect varies greatly from the design and the like. The polypropylene base film comprises a core layer (1), wherein the upper surface and the lower surface of the core layer are respectively provided with an upper surface layer (2) and a lower surface layer (3). The polypropylene base film is characterized in that the core layer (1), the upper surface layer (2) and the lower surface layer (3) are coextruded into a whole through thermal melting, the upper surface layer is a corona print layer, and the lower surface layer is a non-corona layer.
Description
Technical field
The utility model relates to a kind of polypropylene basement membrane, especially relates to a kind of bidirection drawed BOPP film that is used to print.
Background technology
At present, the known basement membrane that is used to print is the basement membrane with PP (HOPP) raw material production.Chinese patent discloses a kind of high heat insulating two-way oriented polypropylene basement membrane, and (Granted publication number: CN200975586), its basement membrane is by upper epidermis, sandwich layer, the top layer constitutes down, and sandwich layer is between upper and lower top layer; The thickness on upper epidermis, following top layer is respectively the 5-10% of basement membrane thickness.Chinese patent also discloses a kind of Polywoven Bag composite bidirectional stretching polypropylene basement membrane (Granted publication number: CN200981364) that is used for; It comprises the intermediate layer; Constituting by upper strata and lower floor respectively up and down of intermediate layer; The thickness of upper strata, lower floor is respectively the 6-10% of intermediate layer thickness, and upper strata, intermediate layer, lower floor's major ingredient all adopt polypropylene plastics.But these two kinds of basement membranes can only carry out some low levels, and less demanding printing if carry out the phenomenon that chromatography is inaccurate or cover is not painted can often occurring when some higher class print, makes pattern true to nature inadequately, differs bigger with design.
The utility model content
The utility model provides a kind of bidirection drawed BOPP film that is used to print; It mainly is to solve the existing in prior technology basement membrane can only carry out some low levels; Less demanding printing; If the phenomenon that chromatography is inaccurate or cover is not painted can often occur when carrying out some higher class printings, make pattern true to nature inadequately, differ technical problem such as bigger with design.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The bidirection drawed BOPP film that is used to print of the utility model; Comprise sandwich layer, the upper and lower surfaces of sandwich layer is respectively equipped with upper epidermis, following top layer, and described sandwich layer, upper epidermis, following top layer become one through the hot melt co-extrusion; Wherein upper epidermis is the corona printed layers, and following top layer is non-corona layer.To above-mentioned technical problem, the utility model is at upper epidermis, and just the corona printed layers has added the surface appearance that a kind of auxiliary agent has changed basement membrane; Use basement membrane can carry out multi-level; Coloury printing makes printed patterns more accurate, and the surface is fine and smooth more; Thereby widened product applications for downstream user, it is simple and reasonable for structure.
Utilize this kind basement membrane can carry out the printing of different class, particularly high-grade printing uses printed patterns more lively, more true to nature.Basement membrane can cut into the finished product of different specification size (length and width) according to user's demands of different.Also can utilize different stretch processes to produce the basement membrane of different-thickness.
As preferably, described upper epidermis, the thickness on top layer is respectively 4%-8% of whole basement membrane thickness down, like this product printing effect the best.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Parts, position and numbering among the figure: sandwich layer 1, upper epidermis 2, following top layer 3.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: the bidirection drawed BOPP film that is used to print of this example; Like Fig. 1; One deck sandwich layer 1 is arranged, and the upper and lower surfaces of sandwich layer is respectively equipped with upper epidermis 2, following top layer 3, and sandwich layer, upper epidermis, following top layer become one through the hot melt co-extrusion; Wherein upper epidermis is the corona printed layers, and following top layer is non-corona layer.The thickness on upper epidermis, following top layer is respectively 8% of whole basement membrane thickness.
During use, basement membrane can cut into the finished product of different specification size according to user's demands of different, also can utilize different stretch processes to produce the basement membrane of different-thickness.
The above is merely the specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
Claims (2)
1. bidirection drawed BOPP film that is used to print; Comprise sandwich layer (1); The upper and lower surfaces of sandwich layer is respectively equipped with upper epidermis (2), following top layer (3); It is characterized in that described sandwich layer (1), upper epidermis (2), following top layer (3) become one through the hot melt co-extrusion, wherein upper epidermis is the corona printed layers, and following top layer is non-corona layer.
2. the bidirection drawed BOPP film that is used to print according to claim 1 is characterized in that the thickness on described upper epidermis (2), following top layer (3) is respectively 4%-8% of whole basement membrane thickness.
