Discussion on the importance of hot stamping die cutting process in wine packaging production

In recent years, with the increase in the consumption of alcohol, especially white wine, the wine packaging market has expanded rapidly and has gradually become a relatively high-ranking sector in China's social packaging products. Among the top 100 Chinese printing companies in 2015, 2 out of the top 15 were printing companies with wine packaging as their main business. It can be seen that the development of the wine packaging market is quite large. In contrast, wine packaging on demand, function, structure, materials and processing technology has a significant difference from other packaging products, especially hot stamping and die-cutting process, essential in the production process after wine packaging India, the boutique In the production of wine packaging, the amount of hot stamping and die cutting is even much higher than the amount of printing.

Application characteristics of wine packaging hot stamping process

The hot stamping area of ​​the wine packaging is large, and the hot stamping plate is usually made by etching the copper plate. Considering that the positioning accuracy of the hot stamping device is lower than that of the printing device , and the hot stamping and printing have a long time interval, the hot stamping plate can be appropriately prepared. Make trapping treatment to ensure accurate binding of hot stamping graphics and printing, embossing and other graphic. In principle, the hot stamping text is unchanged, and the printed graphic is diffused into the hot stamping text, and the maximum value can reach one-half of the width of the hot stamping graphic. Images that are too small and need to be white need to be enlarged and bolded to prevent paste and lack of pen.

If the hot stamping pattern is to be pressed and embossed, the electronic engraving version can be made by hot stamping and embossing once the cost is considered, so that the fitting error between the hot stamping and the embossing can be eliminated, and the process is combined. It can also reduce the production processing volume by half. Of course, in order to make full use of the hot stamping foil, the hot stamping process also needs to set the skipping method and the skipping value of the hot stamping.

Application trend of wine packaging hot stamping process

1. Diversification of materials and processing methods

In order to enrich the hot stamping performance of wine packaging and meet the anti-counterfeiting needs of wine packaging, the positioning hot stamping process and the corresponding laser holographic hot stamping foil have also been promoted from the cigarette pack field to the wine packaging field, which not only makes the hot stamping effect of the wine packaging obtained. Beautification also gives it a certain anti-counterfeiting function. Moreover, the lithography Fresnel lens "cat's eye" hot stamping foil is available, which enables the "cat's eye" effect on the wine packaging through the hot stamping process, without having to use the entire laser holographic special edition positioning paper, which greatly reduces the Cost of production.

At the same time, the hot stamping production technology is constantly being updated, making the hot stamping surface of the wine packaging no longer a simple plane, but showing a multi-layer effect, and can also produce a micro-pressure shading pattern, which is improving At the same time, the wine packaging surface has a certain anti-counterfeiting function.

2. Application of cold stamping process

Cold stamping is a new process in which cold and hot foil is printed on a printing material by using a cold stamping device, and then the cold foil is combined with pressure, and then the cold foil is peeled off. The cold stamping process has two types: dry film type and wet film type. It is characterized by large-area hot stamping fine text (fine text or even dot), and can be printed after hot stamping, which greatly enriches the expressiveness of hot stamping. It complements the printing process and brings a strong visual impact to the wine packaging.

3. New materials replace part of the hot stamping process

In fact, the hot stamping process also has some shortcomings in the post-printing process, such as complex graphic hot stamping processing and high energy consumption. In recent years, laser holographic positioning paper has been applied as a new printing material in post-press processing of wine packaging. It has the visual effects of special edition, laser lithography and holographic pattern. The pattern is gorgeous and diverse, and the contrast between light and dark is strong. Anti-counterfeiting means. The application of this material has greatly reduced the amount of post-press processing, and has now replaced some of the hot stamping processes used in post-press processing of wine packaging.

4. Development and improvement of high efficiency hot stamping equipment

Through the research and development of equipment suppliers, the production capacity and functions of hot stamping equipment have been further improved, such as the modularization of hot stamping equipment, the increase of multi-station hot stamping function, the improvement of hot stamping registration accuracy, and the processing efficiency. And the improvement of quality has increased the production capacity of wine packaging enterprises, and won the market competitiveness with excellent product quality.
