Carton packaging printing hot stamping technology

Cold hot stamping does not require the use of heated metal plates, but transfers the metal foil using printing adhesives. The cold stamping process has a low cost, saves energy, and has high production efficiency. It is a promising new process.

Concavo-convex hot stamping (also known as three-dimensional hot stamping) is the use of modern engraving technology to make the upper and lower female and male molds. The hot stamping and pressing and bumping processes are completed at one time, which improves the production efficiency. The mold made by electric engraving can be curved surface transition to achieve a three-dimensional relief effect that is difficult to achieve by the mold made by the general corrosion method. The appearance of uneven hot stamping makes the hot stamping and embossing processes complete at the same time, reducing the process and waste products caused by inaccurate overprinting.

The holographic logo uses computer technology to change the amplitude and frequency of the grating to make its effect more brilliant and clearer than the calculated color of the pattern. If this kind of holographic mark is used as a copy of the original, a large amount of holographic loss will occur, thereby achieving the purpose of anti-counterfeiting. The holographic logo can not only have very good anti-counterfeiting performance, but also can make special numbers or words in the holographic logo according to the needs of customers.

New challenges for paper stickers

Detailed description: The new challenge of paper stickers-flexographic printing occupies a considerable share in the commodity label market, and the important role of commodity labels in commodity sales. Therefore, the product label must be beautifully designed, eye-catching, and attractive, so that people will reluctantly look at the first sight, and finally pay for it. As the saying goes, "love at first sight" can best represent the role of the product label.

There are many varieties of commodity labels, and they are constantly evolving with the development of the market and technology. In recent decades, pressure-sensitive labels (or self-adhesive labels) have continuously expanded their share in the label market due to their ease of use and other advantages. However, whether such a large growth rate can always be maintained in the future is not necessarily true. Because the pressure-sensitive type also has its shortcomings, the most important one is easy to be counterfeited. Therefore, in recent years, the application of non-pressure sensitive labels has also increased. The 2001 North American Commodity Research Report, based on the survey results of more than 800 users of various packaging containers in the United States, Canada and Mexico, believes that in the next three years, the share of labels changed from pressure-sensitive labels to other methods will be as follows:

1. Turn to roll type accounted for 13%

2. Turning to in-mold molding accounts for 9%

3. Turning to direct screen printing accounted for 6%

4. Maintain 72% of the pressure-sensitive type

This is related to the growing development of the production of commodity packaging containers with plastic instead of glass or metal materials. According to statistics: In recent years, the plastic container market in North America has been as large as 11 billion US dollars, with an annual growth rate of about 10%, of which PET (polyester) is the largest, followed by HDPE (high density polyethylene), PC (polycarbonate), PP (Polypropylene), PVC (polyvinyl chloride), etc.

1. The so-called roll-type labels are mostly plastic film type (including sleeve type, wrap-around type, heat shrinkable type, etc.); most of them are used for PET beverage containers, packaging of carbonated drinks, fruit juice, ready-to-use Type tea drinks, etc. Because PET containers are suitable for hot filling.

2. The so-called in-mold molding refers to placing the printed label in the molding mold of the plastic container. When the plastic container is molded in the mold, the label is bonded to the surface of the molten container. After cooling, it is fixed and fixed, especially It is best for HDPE containers.

In the pressure-sensitive commodity labels, there are two types of paper and plastic films. They have the same advantages: easy processing, suitable for a variety of printing processes, and convenient storage, saving space, can be used at any time according to variety and demand. But the latter is better than the former in water resistance, abrasion resistance, tear resistance and other properties. Some films, such as polyolefins, are also particularly heat-resistant and freeze-resistant without aliasing, so they are suitable for food or beverage packaging labels that require high-temperature sterilization and hot-filling, as well as frozen storage. Such as BOPP (bidirectional polypropylene) not only resists high temperature and freezing, but also resists sour and spicy odor without discoloring the ink. Such characteristics of plastic film labels are suitable for the environmental requirements of online production and processing of food and beverages, and are welcomed by businesses.
