Description

  The present invention relates to a method for processing a surface glossy processed printed material and a surface glossy processed printed material used for a paper container blank or the like that is punched into a suitable shape according to various uses.

  In the surface gloss processing of a surface gloss processed printed material used for a paper container blank or the like, for example, a vinyl drawing machine 100 as shown in FIG. 3, an endless press machine 200 as shown in FIG. 4, or a vinyl press machine 300 as shown in FIG. Alternatively, a film applicator, a UV coater or the like is used.

  The resin used is generally a thermoplastic resin or a vinyl chloride / vinyl acetate copolymer resin.

  Of these, those having a low degree of polymerization are often used. Aqueousization has progressed and styrene / acrylic aqueous resins are also used.

  Endless press processing or vinyl press processing is used when gloss is required rather than vinyl drawing. The endless press 200 includes a paper feeding unit 106, a coating unit 107, a drying unit 108, and a glazing unit 109 as shown in FIG.

  Further, as a high-grade paper container application, there is also used a surface gloss processing method in which a UV coat having a high coating film resistance is applied and instantly cured by irradiation with a UV lamp. The coating method is either one of a pattern method and a roll coating method.
