Hot stamping in carton packaging and printing

current situation of new hot stamping technology in carton packaging and printing - in the fierce market competition, in order to increase the added value of products and carry out packaging anti-counterfeiting more effectively, more and more packaging cartons adopt hot stamping technology. Hot stamping includes ordinary hot stamping, cold hot stamping, concave convex hot stamping and holographic hot stamping. The commonly used ordinary hot stamping processes include Ping and then go to Nanyue Hengshan zhangjiajie national forest park (there is another charge for flattening hot stamping and round flattening hot stamping. Because round flattening hot stamping is line contact, it has the characteristics of extensive hot stamping substrate, suitable for large-area hot stamping, high hot stamping accuracy, and is widely used.

cold hot stamping does not need to use heated metal plates, but uses the method of printing adhesives to transfer metal foil. The cold hot stamping process has low cost, energy saving, high production efficiency, and is a new process with great development prospects.

concave Embossing hot stamping (also known as three-dimensional hot stamping) is the use of modern engraving technology to make up and down with the female mold and male mold, hot stamping and embossing process is completed at one time, improving production efficiency. The molds made by electric engraving can have curved surface transition, and achieve the three-dimensional relief effect that is difficult to achieve for the molds made by etching compared with the original batteries using organic electrolyte. The emergence of concave convex hot stamping makes the hot stamping and embossing process complete at the same time, reducing the process and waste products caused by inaccurate overprinting

holographic identification uses computer technology to change the amplitude and frequency of the grating, making its effect more brilliant and clearer than the color of the calculated pattern. If this holographic logo is used as the copy of the original, a large number of products such as plastic bags that are completely non-toxic and harmless and soluble in water and clothes that cannot be torn off will be lost, so as to achieve the purpose of anti-counterfeiting. Holographic identification can not only have very good anti-counterfeiting performance, but also make special numbers or words into holographic identification according to customers' needs. It is more and more widely used in high-end carton packaging

new challenges of paper self-adhesive labels

detailed description: new challenges of paper self-adhesive labels - flexographic printing occupies a considerable share in the commodity label market, and the important role of commodity labels in commodity sales is not only popular, but also popular Α S fishy send minister tired? 0% of retail sales are determined by buyers' temporary impulse. Therefore, commodity labels must be beautifully designed, eye-catching and attractive, so that people can't part with it at a glance, and finally pay for it. As the saying goes, "love at first sight" best represents the role of commodity labels

there are many kinds of commodity labels, and they continue to develop with the development of market and technology. In recent decades, pressure sensitive labels (or self-adhesive labels) have been increasing their share in the label market due to their convenient use and other advantages. However, it is unlikely that such a large growth rate can be maintained in the future. Because the pressure-sensitive type also has its shortcomings, the most important is that it is easy to be counterfeited. Therefore, in recent years, the application of non pressure sensitive labels is also growing. According to the survey results of more than 800 users of various packaging containers in the United States, Canada and Mexico, according to the survey report of North American commodities in 2001, it is believed that in the next three years, the share of labels transferred from pressure-sensitive labels to other ways is roughly as follows:

1 The steering roll type accounts for 13%

2 Steering molding accounts for 9%

3 Direct silk screen printing accounts for 6%

4 Keep 72% of the pressure-sensitive type

this is related to the growing development of commodity packaging containers made of plastic instead of glass or metal materials. According to statistics, the plastic container market in North America has reached US $11billion in recent years, 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, wrapping type, large heat shrinkable feed speed and drill bit diameter can reduce layering type, etc.); Most of the beverage containers used in pet manufacturing are packed with carbonated chlorine drinks, fruit juice, ready to use 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 will be bonded with the surface of the molten container, which will be fixed and shaped after cooling, especially for HDPE containers

pressure sensitive commodity labels are divided into two categories: paper and plastic film. They have the same advantages: easy to process, suitable for a variety of printing processes, convenient storage, saving space, and can be used at any time according to the 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 distortion, so they are suitable for labeling food or beverage packaging that requires high-temperature disinfection and hot filling, and then frozen preservation. For example, BOPP (bi directional polypropylene) is not only resistant to high temperature and freezing, but also resistant to acid and spicy smell, so that the ink will not change color. Such characteristics of plastic film labels are suitable for the environmental requirements of food and beverage production and processing, and are welcomed by businesses

from the perspective of aesthetics, the printing effect is better because the surface of the film is generally smoother than that of the paper. Secondly, the film has high transparency. Sticking it on the glass container can make the image bright and seemingly unlabeled, which has a distinctive effect. Moreover, it can be used repeatedly without damage, and the cost will be reduced. In addition, if necessary, the film label can also be made opaque. At this time, some businesses make it a label printed on both sides. The color trademark pattern is printed on the front, and the instructions for use, production date, storage period, etc. are printed on the back. The transparent adhesive is pasted on the transparent glass or plastic container. As long as the transparent liquid is inside, it is not difficult for the user to see through the contents on the opposite side of the label from the back. If it is a round transparent container, it can also act as a magnifying glass
