Digital printing single-side perspective PVC (polyvinyl chloride) black and white film and fabrication process of black and white film

Abstract

The invention provides a digital printing single-side perspective PVC (polyvinyl chloride) black and white film for realizing the technical effect of good shading property and high peel strength. The black and white film comprises a layer of white PVC film and a layer of black PVC film, wherein the thickness of the white PVC film is 0.07-0.08mm, and the thickness of the black PVC film is 0.06-0.07mm. The fabrication method comprises white PVC film unrolling, a surface film roll preheating, black PVC film unrolling, a bottom film roll preheating, press fitting, vat heating and blending, conveying and heating, press fitting, cooling and rolling steps. The black and white film solves the technical problems that the adhesive force is poor when the traditional white PVC film is printed with black printing ink or coated with black rubber products, the black rubber and the printing ink easily fall off, and the shading property and single-side perspective effect are influenced; meanwhile, the fabrication process is more environmentally friendly due to no use of solvent and printing ink.

Description

technical field [0001] The invention is applied to advertising materials for indoor and outdoor advertising, in particular to a digitally printed one-way perspective PVC black-and-white film and its manufacturing process. Background technique [0002] The main material needed for the production of digital printing one-way perspective products for automobile body glass advertisements, glass curtain wall advertisements, and shopping mall glass window advertisements is PVC film. The full name of PVC is Polyvinylchlorid, and the main component is polyvinyl chloride. The traditional manufacturing process is generally Use a calender to calender the white PVC film, and at the same time print a layer of solvent-based black ink or coat a layer of black glue on the bottom of the white PVC film. The printed ink product has a thinner printing layer, the difference between the ink and the PVC film Poor adhesion, black ink is easy to peel off, destroying the light-shielding and one-way pe...

Problems solved by technology

[0002] The main material needed for the production of digital printing one-way perspective products for automobile body glass advertisements, glass curtain wall advertisements, and shopping mall glass window advertisements is PVC film. The full name of PVC is Polyvinylchlorid, and the main component is polyvinyl chloride. The traditional manufacturing process is generally Use a calender to calender the white PVC film, and at the same time print a layer of solvent-based black ink or coat a layer of black glue on the bottom of the white PVC film. The printed ink product has a thinner printing layer, the difference between the ink and the PVC film Poor adhesion, black ink is easy to peel off, destroying the light-shielding and one-way perspective effect of the product, causing the problem of double-sided perspective, and the use of solvent-based inks leads to poor operating and production environments, and poor environmental performance of the product; black glue coated Due to the poor adhesive properties of the product, the coating layer is relatively thin, which will also affect the adhesion of the product. The black glue is easy to fall off, which also affects the shading and use effect of the product
