Brief description of the drawings
Fig. 1 is cross-sectional view of the present invention.
In figure:
1-common paper; 2-adhesive layer; 3-PP rete.
Now the invention will be further described with specific embodiment by reference to the accompanying drawings.
Detailed description of the invention
As shown in Figure 1, a kind of composite sheet of the present invention, comprises common paper 1, and the end face of described common paper 1 is disposed with an adhesive layer 2 and a PP rete 3 from the bottom to top; The bottom surface of described common paper 1 is disposed with an adhesive layer 2 and a PP rete 3 from top to bottom.Described common paper 1 is printing or hard card paper; Described adhesive layer 2 is water-borne pressure sensitive adhesive layer.
Composite sheet entirety of the present invention is very attractive in appearance.If need print on composite sheet, can be first in common paper, after printing, on common paper two sides, PP film be set again, because water-borne pressure sensitive adhesive layer transparent effect after condensing is good and be difficult for yellowing, pattern in common paper can be known and be presented to the external world; With directly on PP material compared with printing, owing to being paper in the middle of composite sheet of the present invention, so that the sharpness of dots of the present invention's printing, plumpness all directly prints than conventional P P is much eager to excel in whatever one does, color is also more bright and new beautiful than conventional P P.Because the end face in common paper and bottom surface are provided with PP film, make the present invention be not easy, by wrinkle, to tear; And by can be by the directly wiped clean such as rag after being made dirty, very convenient.
The present invention is because it is for being provided with a kind of composite sheet of PP film in the end face of common paper and bottom surface, and it has kept plastics texture and the hardness feature of conventional P P product, so can replace conventional P P materials'use in many-side.And the dilatability of being heated of catching a cold is as good as with conventional P P to the temperature range of 50 degree above freezing at subzero 30 degree.
