Problems solved by technology

The disadvantage of this process is that the surface finishing effect is relatively simple, and the friction resistance is relatively poor, usually between 70% and 80%.
However, if it is a three-dimensional carton and is packaged in an automatic packaging machine line, since the three-dimensional carton runs in a three-dimensional form on the packaging machine line, the friction force between the corners and the metal parts such as the guide rail of the packaging machine line is relatively high. Large, the existing glazing process cannot protect the printed graphics well, and the surface of the packaging box is more scratched
Although the lamination process can avoid scratches and scratches on the printed graphics and text, it needs to add a lamination production process, which will affect the production efficiency of the product and increase the loss
In addition, the coated paper is not easy to degrade, making the packaging carton not environmentally friendly

Embodiment 1

[0040] Take a small paper cigarette packaging box as an example for illustration. The packaging box is a three-dimensional formed carton and is packaged by an automatic packaging machine assembly line. The paper of the carton is 240g / m 2 The PET silver cardboard first uses the sheet-fed gravure printing process to print the base color, and then uses a multi-color UV offset printing machine to coat the surface of the packaging box with tactile effect ink and print the pattern text simultaneously. Firstly, the tactile effect ink is coated on the first color group of the multi-color UV offset printing machine, and the coating position is at the corner after the three-dimensional molding of the packaging box. The printing plate of the tactile effect ink adopts CTP plate making, and the tactile effect finishing area on the printing plate is solid. The configuration of tactile effect ink is as follows (by weight): 48% polyurethane resin, 19% epoxy resin, 4% tripropylene glycol diac...

Embodiment 2

[0043] Take a paper cigarette packaging carton as an example for illustration. The packaging box is a folding carton and is packed in an automatic packaging machine assembly line. The paper used for the printing of this carton is 250g / m 2The aluminum-sprayed silver cardboard first adopts the sheet-fed gravure printing process to print the base color, and then uses a multi-color UV offset printing machine to coat the surface of the packaging box with tactile effect ink and print the pattern text simultaneously. First, apply the tactile effect ink on the first color group of the multi-color UV offset printing machine, and the coating position is on the side of the packaging box after three-dimensional molding. The printing plate of the tactile effect ink adopts CTP plate making, and the tactile effect finishing area on the printing plate is solid. The configuration of the tactile effect printing ink is as follows (by weight): 44% polyurethane resin, 25% epoxy resin, 3% tripropy...

Embodiment 3

[0046] Take a paper cosmetic packaging box as an example for illustration. The packaging box is a folding carton and is packaged by an automatic packaging machine assembly line. The paper used for the printing of this carton is 295g / m 2 The white cardboard is firstly printed with a sheet-fed gravure printing process, and then a multi-color UV offset printing machine is used to apply tactile effect ink on the surface of the printed sheet of the packaging box and simultaneously print the pattern text. First, apply the tactile effect ink on the first color group of the multi-color UV offset printing machine, and the coating position is on the side of the packaging box after three-dimensional molding. The printing plate of the tactile effect ink adopts CTP plate making, and the tactile effect finishing area on the printing plate is solid. The configuration of the tactile effect printing ink is as follows (by weight): 50% polyurethane resin, 15% epoxy resin, 6% tripropylene glycol...

Abstract

The invention relates to the field of packing and printing, and especially relates to a printing ink with a tough effect and a surface finishing technology for paper packing boxes. The printing ink comprises following raw materials in percentage by weight: 43 to 53% of polyurethane resin, 15 to 25% of epoxy resin, 3 to 6% of tri(propylene glycol) diacrylate, 3 to 6% of polyethylene wax, 1 to 3% ofphoto initiator TPO, 1 to 3% of photo initiator 369, 4 to 10% of silica, 4 to 8% of talcum powder, and 6 to 10% of bentonite. The printing ink is used to decorate the surface of a paper packing box by the provided surface finishing technology. The surface of the processed paper packing box has dark luster. People can feel flannelette touch when touching the surface of the paper packing box. The appearance of the paper packing box is upgraded, and the wear resistant performance of the surface of the paper packing box is strengthened.

Description

technical field [0001] The invention relates to the field of packaging printing, in particular to a tactile effect ink and its surface finishing process for paper packaging boxes. Background technique [0002] At present, the printing surface of paper packaging boxes mainly adopts glazing and lamination process for surface finishing. On the one hand, it makes the surface of the packaging box more glossy, and on the other hand, it prevents the graphics and texts printed on the surface of the packaging box from being scratched. The existing glazing process can be completed on-line printing on a multi-color printing machine, or can be glazing separately after graphic printing. The disadvantage of this process is that the surface finishing effect is relatively simple, and the friction resistance is relatively poor, usually 70% to 80%. In the case of flat sheet or folding carton packaging, this level of abrasion resistance generally ensures that the printed surface of the box wi...
