V. Description of the Invention (1) [Technical Field The present invention relates to a beautiful and suitable for industrialized continuous production of paperboard structure and its manufacturing method. ' The overall structure formed is actually a person with many superior functions. [Previous technology] According to the traditional paper bags, there are two kinds of color printing. The former is a material-based laminating machine and a boxboard (including teaboard). The latter is more cost-effective than cardboard, copperplate, etc. The ordinary single-piece boxboard of the face material is then laminated with corrugated cardboard to form a through carton and a carton for re-lamination. Low, which is a relatively inexpensive packaging material method, cannot solve the two key links of continuous roll-to-roll color bonding. Due to the high cost, high-end packaging products are also being developed ^ With the development of the science and technology industry,% is up and out. Among them, there is an outer layer, which has the advantages of low cost, good performance, environmental protection, and other advantages. The box is printed with color printing. The structure and its manufacturing method are made of a clear polypropylene synthetic paper layer and a single layer or multiple layers. The use of heated glue and non-heating is an innovative structure and design process. Color printing and yellow kraft paper are used as the surface material. After paper, gray board, white paper, etc.) are combined with high and high wood pulp type white paper and white plate, the paper is printed with yellow cattle. It can be re-laminated to make color-printed cardboard, carton, or directly made with ordinary non-color-printed cardboard. The cost of manufacturing is more than that of traditional color-printed cardboard. The manufacturing cost of carton boxes is higher. # Some new composite paperboard products are available in the market ~ A kind of packaging paperboard using biaxially oriented polypropylene film as W, although it has

200526410 V. Description of the invention (2) -------- Waterproof and color printing effects, but there are still the following shortcomings: 1. Bidirectionally stretched polypropylene film (referred to as 0pp film), even when laminated on white paper, Cannot show the writing characteristics of paper. 2. Printing on the gravure printing machine can only be printed on the back (also called bottom printing), but not on the front (also known as surface printing). After the back printing, the film itself is left to print. It does not show the imaging effect alone, so Composite can only choose white paper contrast. 3. It can only be printed first and then compounded, but not compounded and then printed. 4. When recompression with white paper, solvent-based glue (also known as water-based glue) is used. Therefore, when wet composite molding, some small bubbles are easy to appear and affect the impression of 〇PP film. . 5. Due to the high transparency of the OPP film, the printing effect on the back side of the OPP film will continue to appear as a multicolored or drifting image due to the horizontal and vertical extension of the film itself. ’6. Because of the use of 〇 P p film and water-based glue, it cannot meet the requirements for the consistent operation of automated box making. How to effectively avoid the above-mentioned shortcomings is the direction of the efforts and development of all relevant industry players. In view of the knowledge, the inventor of this case has been engaged in the design experience of the industry for many years, and in the spirit of excellence, actively researches and improves, continuously innovates and tests, and devotes himself to the design and development of this technology.

It achieves 1. Because non-transparent polypropylene fiber is non-toxic and odorless, it can be green products, so, Color-printed composite cardboard for non-transparent boxes also has important characteristics that meet environmental requirements. 2. As it can form a continuous work-in-combination or continuous film compound and rolls of color, which improves the original production method, the low utilization rate and labor efficiency of the original production method. 3. The problem of serious cost at the current stage is successfully solved. The wide color continuous roll printing makes it a large-scale color basis that exceeds paper specifications. At the same time, non-transparent polypropylene products are produced on order, which will greatly reduce the large area loss and waste. 4. The use of kraft paper or whiteboard has thickness and strength requirements, no cracking), and using one-thickness of the method of the present invention can withstand excessively making the box, which increases the pressure resistance and piercing resistance of the box, low cost, good performance, Environmental protection and beauty. Other purposes of color printing composite cardboard for packaging boxes are as follows: Synthetic paper itself does not contain wood pulp, does not contain plant times for recycling, and is a secondary pollution-free polypropylene synthetic paper for packaging. The characteristics of repeated recycling of the box are a disadvantage of the high production cost caused by the inconsistent operation process of the color printing paperboard manufacturing process of roll printing and continuous copying color printing cardboard production. The packaging paper is limited by the width and loss. The width of the wave printing is much larger than that of the lithographic printing. The longitudinal pattern can be arbitrarily extended. The production of this color packaging box product lays down the width and width of the synthetic paper. When lithographic color printing often occurs when the paper is used as the cardboard face of the packaging box, it is difficult to be folded into a box by the die (it will break 'not only the six-pass folding requirement of the original cardboard face paper, but also a large wear And save a lot of paper products into
