Flexographic printing occupies a considerable share in the commodity label market, and the important role of commodity labels in commodity sales is the driving force for the continuous expansion of commodity labels. According to some statistics, 70% of retail sales are determined by buyers' impulse temporarily. Therefore, the product label must be designed exquisitely, eye-catchingly, and attractively. As the saying goes, "love at first sight" best represents the role of product labels.
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 advantages such as ease of use. However, whether we can always maintain such a large growth rate in the future is not necessarily true. Because the pressure-sensitive type also has its shortcomings, the most important one is that it is easy to be counterfeited. Therefore, in recent years, the application of non-pressure-sensitive labels has also increased. According to the survey report of North American Commodities in 2001, based on the survey results of more than 800 users in various packaging containers in the United States, Canada, and Mexico, it is believed that in the next three years, the shares of labels transferred from pressure-sensitive labels to other methods are roughly as follows:
1. Turning roll sleeve type accounted for 13%
2. Turn to in-mold molding to account for 9%
3. Shift to direct screen printing accounted for 6%
4. Maintain 72% of pressure-sensitive type
This is related to the increasing development of the manufacture of commodity packaging containers with plastics instead of glass or metal materials. According to statistics: In recent years, the North American plastic container market has reached 11 billion U.S. dollars, with an annual growth rate of about 10%. Among them, PET (polyester) is the most, followed by HDPE (high-density polyethylene), PC (polycarbonate), and PP. (Polypropylene), PVC (Polyvinyl Chloride), etc.
1. The so-called roll sleeve type labels are mostly plastic film type (including sleeve type, wrapping type, heat shrinkable type, etc.); most of them are used for beverage containers made of PET, and the packaging is filled with carbonated beverages, fruit juices, and ready-to-use Type tea beverages and so on. 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 container in the molten state, and it is fixed and shaped after cooling, especially It is best suitable for HDPE containers.
In the pressure-sensitive product label, it is divided into two categories: paper and plastic film. They have the same advantages: easy to process, suitable for a variety of printing processes, and convenient to store, save space, and can be used at any time according to the variety and quantity required. However, the latter is better than the former in terms of water resistance, abrasion resistance and tear resistance. Some films, such as polyolefins, are also particularly heat-resistant, frost-resistant, and non-aliasing, so they are suitable for labeling food or beverage packaging that requires high-temperature sterilization and hot-filling, and then freeze-preservation. For example, BOPP (Double Oriented Polypropylene) is not only resistant to high temperature and freezing, but also resistant to hot and sour odors without discoloring the ink. Such characteristics of plastic film labels are suitable for the environmental requirements of online food and beverage production and processing, and are welcomed by businesses.
From the aesthetic point of view, since the surface of the film is generally smoother than that of paper, the printing effect is better. Secondly, the film has high transparency, and it can make the image clear and unlabeled when attached to the glass container, which has a unique effect. Moreover, it can be used repeatedly without damage and the cost is reduced. In addition, if necessary, the film-type label can also be made opaque. At this time, some businesses make it into a label printed on both sides. Color logos are printed on the front, and instructions for use, production date, shelf life, etc. are printed on the reverse. It is attached to a transparent glass or plastic container with a transparent adhesive. As long as the inside is a transparent liquid, it is not difficult for the user to see from the back to the reverse of the label. Content. If it is a round transparent container, it can also function as a magnifying glass.
