A simultaneous printing process of double-sided symmetrical embossing for tipping paper

Abstract

The invention discloses a double-face symmetric embossing and synchronous printing technology for tipping paper. The conventional tipping paper embossing technology includes subjecting the tipping paper to fully embossing by integrating a relief printing plate and an intaglio printing plate, causing the problem that the tipping paper is easily to be crushed and damaged. The double-face symmetric embossing and synchronous printing technology includes the steps of A, performing unreeling; B, performing preheating; C, performing wetting-back; D, performing tension control; E, performing embossing and printing, to be specific, the tipping paper passes a space between an embossing roller with a protrusion with preset patterns or words and a light roller which is used with the embossing roller, and an embossing segment is formed with embossing effect on the tipping paper; F, performing reeling and cutting. In this way, the front and the back of the tipping paper are embossed and printed at a time, production cost is lowered, good printing effect is realized, lines on the printing patterns are accurately matched to highlight embossing effect, the back of the tipping paper is printed with an embossing pattern symmetric with that on the front meanwhile, and accordingly a three-dimensional integral pattern with ink color is formed and anti-fake function is facilitated.

Description

technical field [0001] The invention relates to a cigarette wrapping material and a production method thereof, in particular to a method of embossing printing to realize symmetrical three-dimensional patterns at specific positions on both sides of the tipping paper, and the tipping paper with the above patterns. Background technique [0002] Tipping paper is the paper used to wrap the filter rod and connect the filter rod with the cigarette rod. As an important part of the appearance of cigarettes, tipping paper will directly affect the overall perception of consumers on cigarettes. It plays an important role in improving the appearance quality of cigarettes. [0003] In order to improve the appearance quality of cigarettes, patterns are generally set on the base paper of tipping paper by means of printing or hot stamping. Since the tipping paper is directly in contact with the hands and mouths of consumers, the requirements for printing or hot stamping techniques and raw ma...

Problems solved by technology

[0004] According to the production status of domestic tipping papers, the existing embossed tipping papers are all made of paper, and then the tipping papers are embossed with a concave and convex plate, but this method is easy to make the tipping papers The interconnected fibers on the upper surface are torn, causing structural damage, and there is a problem that it is easy to be crushed and damaged

For example, the Chinese patents "200820167472.6, embossed tipping paper" and "201220151583.4, an embossed cigarette tipping paper", both of which limit the embossing with concave and convex surfaces on the entire outer surface of the tipping paper, but None of the specific implementation solutions are provided. It can be understood that the embossing on the tipping paper is embossed in the way of concave-convex plate cooperation.

[0005] In addition, the existing types and techniques of embossed tipping paper basically avoid an important problem. They all consider tipping paper as a decorative material, and pay too much attention to patterns and color matching. In terms of improving aesthetics, the performance characteristics that tipping paper must have as an important packaging material in cigarette rolling are ignored. For example: the influence of tipping paper surface properties on cigarette rolling effect, see Tobacco Science and Technology 2011 In the fourth issue of "Surface Properties of Different Types of Cigarette Tipping Papers and Their Effects on the Splicing Effect", the above two types of embossed tipping papers, whether they are directly embossed or compounded, have different effects on the original tipping papers. Great changes have been made to the surface properties of the tipping paper, but they have not made any instructions on how to meet the splicing effect of the tipping paper after the change, so they all have the deficiency of destroying the original splicing performance of the tipping paper
