[Technical field to which the invention belongs] Xiang LaiiMing is about a kind of color-printed biaxially stretched polypropylene film or color-printed polypropylene pearlescent synthetic paper combined with cardboard or corrugated paper) and a manufacturing method thereof FIELD OF THE INVENTION The present invention relates to a packaging box (box) with a bidirectionally stretched polypropylene film or a color printing biaxially stretched polypropylene film, a color printed biaxially stretched polypropylene 'light synthetic paper, and a packaging box (box) made of corrugated paper. related. [Previous technology]: Carton packaging is a packaging that cannot be separated from all goods. In order to improve the quality of goods, for hundreds of years, people have traditionally improved the aesthetics, increased the strength, expanded the scope of use and applications, and improved the traditional carton printing. A lot of research and improvements have been carried out. In the production of traditional full-paper corrugated boxes, a complete set of production equipment with a high degree of automation has been formed. They are multi-layer corrugated cardboard forming machines and cardboard cutting machines, carton surface paper and cardboard sheet paper printing machines or Paper roll continuous printing machine, corrugated paperboard laminating machine, corrugated cardboard printing slotting machine, carton gluer (box) machine or stapler. The general production process of box making is continuous printing of paper rolls. The multi-layer cardboard is formed into a corrugated shape on the corrugated cardboard forming machine to increase the strength of the cardboard. At the same time, the glue is glued to make the multi-layer corrugated paper and the multi-layer cardboard adhere. Here At the same time, it is pasted with a continuous printed paper roll to form a corrugated reinforced cardboard with a printed pattern on the surface. After the corrugated cardboard is cut to the size specified in the specification, it is placed in a corrugated cardboard printing slotting machine to slot the cutout according to the carton specifications ( Because the surface layer has been printed in rolls, it is no longer printed. If there is no roll printing, the corrugated cardboard is here.

1226866 -_ Case No. 92134004 __Year Month_g_ Amendment ___ V. Description of the invention (2) The surface layer pattern is printed on it). The cut corrugated cardboard is nailed into a prescribed carton on a carton gluer or nailer. At present, traditional cartons are made in this way, but the size and automation of the equipment are different, and the progress of printing machines can produce various cartons faster and more conveniently, improving the aesthetics and large-scale printing of cartons. However, the use of traditional cartons has been greatly restricted. For example, the packaging of refrigerated food, seafood, fruits and vegetables, because the cartons are not moisture-proof, they must be impregnated with wax to prevent moisture in the cold storage. The printing on the surface of the carton and the continuous printing of the roll paper, because the thickness tolerance of the corrugated cardboard is too large, and the surface of the roll paper is too rough, matte, and non-glossy. The exquisiteness and gloss of the printing can not meet the requirements of the product. People began to use cast polypropylene film, polyester film, and biaxially oriented polypropylene film to apply a layer of adhesive on the surface of the film, and then laminating one by one or covering the surface of the cardboard box of the above-mentioned cut cardboard. The printed pattern makes the printed pattern more shiny, smooth and beautiful. It also increases the strength and moisture resistance of the carton, and also expands the scope of use. The printed pattern is printed on cardboard and the surface layer. A plastic film is used to coat a sheet of adhesive. A piece of cardboard and the surface compounding or covering is mainly using the existing traditional equipment and technology such as 0pp laminating machine or CPP laminating machine, and it has indeed achieved the effect of improving the decoration level and the value of packaging boxes and commodities. However, if a printed pattern is printed on a plastic film, especially a biaxially oriented polypropylene film, whether the pattern is printed on the outer or inner surface of the film, the smoothness and saturation of the printing ink plus the smoothness and film of the film Refraction will undoubtedly be more exquisite and more valuable than printing on paper.

Page 6 1226866 _ Case No. 92134004_ + Month Day Amendment V. Description of the Invention (3) Because the film has a strong electrostatic effect, it cannot be printed and overprinted at all. If it is printed with an existing plastic gravure printing machine or flexible convex plate The machine rolls and prints a biaxially stretched polypropylene film, cuts it according to the printing pattern and design, and cuts it. Then, the dry compound machine such as the OPP laminator or CPP laminator is used to apply the adhesive and cut off the corrugation. For paperboard composite, the film is stretched or shortened due to the heating of the adhesive, which affects the strict repetition and length of the printed pattern. If the printed pattern on the film is a fixed length, the aforementioned film may be coated by heating. Corrugated cardboard with different lengths caused by adhesives and corrugated cardboard cut to a fixed length are not neat. In addition, the film has a serious electrostatic effect, which makes it difficult to align with the cardboard during the compounding operation, making the incision of the cardboard behind the slot more inaccurate. Positioning so that the 8 folds and 6 sides of the box could not be aligned with the printed pattern specified in the design, but the printed patterns on each side interfered with each other. Therefore, we still try our best to print exquisite patterns on the market and use a film to pass through the adhesive to the cardboard surface box. A color printing packaging box compounded with a transparent biaxially stretched film or cast paper on the surface layer of the cardboard and a printed paper on the packaging acrylic film or polypropylene synthetic paper is prepared in advance to obtain a packaging box. In order to make the content of the invention, the examiner further understands the content of the feasible age of the present body, and then discusses the content of a, I β, in order to compare the embodiment, with a willingness to carry out only one step to clarify the present invention is specific and feasible.

The color-printed bidirectionally stretched polypropylene film and paperboard or corrugated paper box (box) is composed of a biaxially stretched polypropylene film and a cardboard compounded with a biaxially stretched polypropylene film through a resin layer. The outer surface and / or inner surface of the stretched polypropylene film has a color printing pattern printing layer, and the pattern printing layer has a three-dimensional effect, saturation, layering on the outer surface of the film, adding exquisiteness and physical feeling. This situation uses polypropylene Synthetic paper printing is the best, because the film is pearlescent film, white paper, cardboard can be recycled cardboard. If the traditional printing method is used to print on the surface of the cardboard first and then cover it with a transparent film, there must be no: using this printing color printing effect, the biaxially stretched polypropylene film itself has defects such as non-uniformity and easy tearing, but electrical After the halo treatment, especially the pearlescent 2 paper, it has better printing performance than other films. Then it is compounded with cardboard, and the resistance: secondary resistance: cracking performance has also been improved, and it has become a composite material: real daggers: : Higher strength. … Print the printed pattern on the transparent fortune, to protect the printed pattern. There are: daggers are mostly used for corrugations that require a smooth layer on the surface of the film: there is an inner layer in the packing box, and there is between the surface layer and the innermost layer. Reinforcement made of corrugated cardboard on the outer layer = thin pearlescent synthetic paper with color printing on the outer surface and / or inner surface of the printed pattern on the film: i ::: J 明 = :: structure, color printing There is better transparency.
