解決することを目的とする。However, in the conventional video case manufacturing process using such a polypropylene thin plate, since the above-mentioned many processes are all performed in separate steps, the manufacturing process is This is a factor that is complicated and raises the production cost of the product.Since most of the printing methods are silk screen (SiIk Screen) printing, the printing technique does not allow precise multicolor and primary color printing. Since this is possible, there is a problem in that the quality of the product is hindered, and because the surface printing method is used, the printed surface is contaminated and damaged during the printing operation. And because the finished product is repackaged using another overlapping film manufactured by the gravure printing method, it not only causes a cost increase, but also the printing surface of the opi film used for packaging the finished product and the polypropylene case. There is a problem that the printing surface frequently comes into contact with the printing surface to cause blocking of the printing design during heat shrink packaging. Then, this invention aims at solving the said problem.

The process of manufacturing the polypropylene case constructed as above according to the present invention will be described below. Blender 13 of extruder 1
The polypropylene raw material mixed well in the cylinder 11 and fed into the cylinder 11 is transferred to the die 14 by the screw 12 in a melted state and is extruded into a thin plate with a certain thickness and width determined by the die. The polypropylene thin plate P is subjected to thickness adjustment and embossing while passing through the pressure bonding roller 15 of the cooling unit 1b, is cooled while passing through the cooling roller 16 and is moved to the post-processing roller 17, and the post-processing roller 17 The polypropylene thin plate P passing through 17 is supplied to the interleaf sheet portion 2A of the dry laminator 2 in a flat state through a thickness deviation adjusting process and a curling calibration process. At the same time, the overlapping film mounted on the overlapping film mounting roller 25 (the back side of which is printed by the gravure printing method) is coated with the adhesive on the printed surface by the adhesive coating section 2B, and then the drying section 2C. The adhesive is dried in the process of passing, and the overlapping film F that has passed through the adhesive application section 2B and the drying section 2C in this way is interleaved with the polypropylene thin plate extruded by the extruder 1, and the interleaf section 2A is heated. Rollers 21 and 22
You will pass through. When the overlapping film F and the polypropylene thin plate P pass through the heating rollers 21 and 22, the printing surface of the overlapping film F is laminated on the surface of the polypropylene thin plate P, and the polypropylene thin plate P on which the overlapping film F is laminated is a cooling roller. It is transferred to the gold / silver foil printing machine 3 via 24 and the tension adjusting machine M. Gold and silver foil printing machine 3
The polypropylene thin plate P (which has been laminated with the overlapping film) is printed with a gold foil or a silver foil on a certain portion, and a line is formed while passing through the embossing machine 4, and a punch 5 is formed. After being punched on the finished product while passing, the finished product is transferred to the finished product transfer table 6 and transferred to the loading table (not shown) by the blower (6a). While the polypropylene scrap is passing through the overlapping scrap peeling section 7, the overlapping scrap T having its surface laminated is peeled off, and the polypropylene scrap is wound around the overlapping scrap winding drum 4 and the polypropylene scrap is cut by a cutter C. It is cut by and is collected in the polypropylene scrap collection box 8.

る。According to the present invention as described above, precision printing is performed by producing a polypropylene case for storing a video tape by dry laminating the printed surface of an overlapping film printed by a gravure printing method on the surface of a polypropylene thin plate. Colors and primary colors can be printed, the design can be upgraded, and there is no need to separately treat the surface of the polypropylene thin plate (UV coating, etc.) because it is an internal printing method using an overlapping film. Moreover, since the printing surface is not contaminated and damaged during the printing operation, the defective rate can be remarkably reduced, and only the printing operation of the overlapping film is processed in a separate step, and all other steps are performed. Greatly reduce the production cost of the product because it is integrated into one line It is possible. Further, since the transparent film which is not printed can be used as the overlapping film used for packaging the finished product, it is possible to obtain the effect of preventing the conventional printing surface blocking condition as in the past.
