Flexographic printing has a large share of the merchandise label market, and the important role that merchandise labels play in merchandising is to drive the continual expansion of merchandise labels. According to some statistics, 70% of retail sales are determined by the buyer's temporary impulse. Therefore, the product label must be designed beautifully, conspicuously and enticingly, so that people can be reluctant to look at it at a glance, and finally buy it. As the saying goes, "love at first sight" best represents the role of the product label.
There are many varieties of commodity labels, and they are constantly developing with the development of markets and technologies. In recent decades, pressure-sensitive labels (or self-adhesive labels) have become more and more popular in the label market due to their ease of use. However, it is not necessarily possible to maintain such a large growth rate in the future. Because the pressure-sensitive type also has its inadequacies, the most important ones are easy to be counterfeited. Therefore, in recent years, the application of non-pressure-sensitive labels has also increased. According to the survey results of more than 800 users of various packaging containers in the United States, Canada, and Mexico, the North American Commodity 2001 research report believes that the number of labels transferred from pressure-sensitive labels to other methods will be as follows in the next three years:
1. Turning sleeve type accounts for 13%
2. Steering in-mold forming accounts for 9%
3. Turn to direct screen printing accounted for 6%
4. Maintain 72% of the pressure sensitive type
This is related to the growing popularity of commodity packaging containers in the manufacture of plastic instead of glass or metal materials. According to statistics: in recent years, the plastic container market in North America is 11 billion US dollars, with an annual growth rate of about 10%, of which PET (polyester) is the most, 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 type, heat shrink type, etc.); most of the beverage containers used for PET manufacture, packaged with 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 a molding mold of a plastic container. When the plastic container is molded in the mold, the label is adhered to the surface of the container in a molten state, and is fixed and fixed after cooling. It is best for HDPE containers.
In the pressure-sensitive product label, there are two major categories of paper and plastic film. They have the same advantages: easy to process, suitable for a variety of printing processes, and easy to store, save space, can be used according to the variety at any time. However, the latter is superior to the former in terms of water resistance, abrasion resistance, tear resistance and the like. Some films, such as polyolefins, are also particularly resistant to heat and freeze, so they are suitable for labeling food or beverage packaging that requires both high temperature sterilization and hot filling, followed by cryopreservation. For example, BOPP (Double Oriented Polypropylene) not only is resistant to high temperature and freezing, but also resistant to sour and odor without discoloring the ink. These characteristics of plastic film labels are suitable for the environmental requirements of online production and processing of foods and beverages, and are welcomed by merchants.
From an aesthetic point of view, the printing effect is better because the film surface is generally smoother than the paper. Secondly, the film has high transparency and can be attached to a glass container to make the image clear and unlabeled. It has a distinctive effect. Moreover, it can be used repeatedly and repeatedly, without damage, and the cost is reduced. In addition, the film type label can also be made opaque if necessary, and some merchants make it a two-sided label. The front side is printed with a color logo pattern, the reverse side print instructions, production date, shelf life, etc., and the transparent adhesive is attached to the transparent glass or plastic container. As long as the transparent liquid is contained inside, the user can easily see from the back side to the reverse side of the label. Content. If it is a round transparent container, it can also function as a magnifying glass.
