Abstract
The invention belongs to the technical field of packing materials, in particular to a BOPP (biaxially-oriented polypropylene) matte transfer basement membrane. The BOPP matte transfer basement membrane is characterized by comprising a delustering layer, a sandwich layer and a surface layer, wherein the sandwich layer is positioned between the delustering layer and the surface layer; the delustering layer, the sandwich layer and the surface layer are formed by adopting coextrusion and then adopting two-way stretch; the delustering layer is made of the following materials by mass percent: 20 percent of SO2, 15 percent of titanium pigment and 65 percent of polypropylene; the sandwich layer is made of the following materials by partition ratio: 500 ppm of glycerin monostearate, 500 ppm of erucyl amide, the balance of polypropylene and 1000 ppm of ethoxylated amine; the surface layer is made of the following materials by partition ratio: 2000 ppm of the SO2 and the balance of the polypropylene; and the mass ratio of the materials of the delustering layer to the materials of the sandwich layer to the materials of the surface layer is 1 to 1 to 1. The invention has delustering functions.
Description
Technical field
The invention belongs to field of packaging material, be specifically related to a kind of BOPP transfer basement membrane.
Background technology
Present BOPP transfer basement membrane exists following deficiency: do not have delustering functions.Like the mute light effect of need, be on the BOPP transfer basement membrane of existing light, to be coated with extinction material (needing back processing).
Summary of the invention
The object of the present invention is to provide a kind of mute light transfer basement membrane of BOPP with delustering functions.
To achieve these goals; Technical scheme of the present invention is: the BOPP light transfer basement membrane of making mute; It is characterized in that: it is made up of delustring layer, sandwich layer and top layer, and sandwich layer is between delustring layer and top layer, and coextrusion is adopted after biaxial tension forms in delustring layer, sandwich layer and top layer;
The material of said delustring layer is by SO
2, titanium white powder and polypropylene (PP) form, the shared mass percent of each component is: SO
220%, titanium white powder 15%, polypropylene 65%;
The material of said sandwich layer is that glycerin monostearate, erucyl amide, polypropylene (PP) and ethoxylated amine are formed, and the proportioning of each component is: glycerin monostearate 500ppm, erucyl amide 500ppm, polypropylene (PP) are surplus, ethoxylated amine 1000ppm;
The material on said top layer is by polypropylene (PP) and SO
2Form, the proportioning of each component is: SO
2Be 2000ppm, polypropylene is a surplus;
The material of delustring layer: the material of sandwich layer: the mass ratio of the material on top layer is 1: 1: 1.
The invention has the beneficial effects as follows: adopt delustring layer and sandwich layer and top layer co-extrusion to be integral, BOPP of the present invention is mute, and the light transfer basement membrane has delustering functions.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1-delustring layer, 2-sandwich layer, 3-top layer.
The specific embodiment
As shown in Figure 1, the BOPP light transfer basement membrane of making mute, it is made up of delustring layer 1, sandwich layer 2 and top layer 3, and sandwich layer 2 is between delustring layer 1 and top layer 3, and delustring layer 1, sandwich layer 2 and top layer 3 adopt coextrusion after biaxial tension forms (extrusion temperature is 200-260 ℃);
The material of said delustring layer 1 is by SO
2, titanium white powder and polypropylene (PP) form, the shared mass percent of each component is: SO
220%, titanium white powder 15%, polypropylene 65%;
The material of said sandwich layer 2 (having forwarding function) is that glycerin monostearate, erucyl amide, polypropylene (PP) and ethoxylated amine (ethoxylated amine) are formed, and the proportioning of each component is: glycerin monostearate 500ppm, erucyl amide 500ppm, polypropylene (PP) are surplus, ethoxylated amine 1000ppm;
The material on said top layer 3 is by polypropylene (PP) and SO
2Form, the proportioning of each component is: SO
2Be 2000ppm, polypropylene is a surplus;
The material of delustring layer 1: the material of sandwich layer 2: the mass ratio of the material on top layer 3 is 1: 1: 1.
Preparation method of the present invention is: the raw material of apolegamy is sent into extruder be processed into melt; Melt becomes sheet (extrusion temperature is 200-260 ℃) through curtain coating casting sheet co-extrusion; Sheet becomes film through biaxial tension; Film becomes female film through corona treatment or flame treatment, and parent roll cuts into the mute light transfer basement membrane finished product of BOPP at last through Ageing Treatment.
The mute light transfer basement membrane of BOPP of the present invention is carried out the delustring experiment: detect the mute light transfer basement membrane of proof BOPP of the present invention with the mist degree tester and have delustering functions.
The present invention cited each raw material (comprising different molecular weight, different manufacturers) can both be realized the present invention, does not enumerate embodiment one by one at this.
