Current situation of food packaging label market in the United States

in the United States, IML method is more and more widely used, and labels of various colors can be seen everywhere. The development of UV curable coating label is only an example of label changes

at present, the focus of the label industry is still on 60 and 70 GIS (single-sided coating) label paper. But buyers of glued labels are increasingly turning to plastic synthetic materials. These plastic labels (generally polypropylene) are used on some metal cans, but they are most favored by the beverage industry and are widely used on plastic and glass bottles. The sleeve type with heat shrinkability should also consider the following characteristics in practical application: plastic labels are used not only on metal cans, but also on bottles, because aniline printing is economical and can achieve satisfactory results

as long as food companies still have adhesive labeling machines, they will still choose paper labels to stick on metal cans and bottles. Such labels are occasionally embossed or pressed with metal foil to give them an attractive appearance. But at the same time, it also significantly increases the cost

as mentioned above, the elongation of polymer materials is far better than that of metal, fiber, wood, plate and other materials. In recent years, two major changes have taken place in the field of paper labels, the first is the demand for UV (ultraviolet) cured outer coating, and the second is the use of a wider range of ink colors. Many printing houses can print nine colors in one printing process, so they can print more special colors at little more cost. Special colors can reduce discoloration. Discoloration often occurs when using four-color ink to create a special plastic on the label that is only a quarter of the background or solid background color of steel

most trademark buyers pay special attention to some basic quality factors, which are divided into appearance and functionality

in the category of appearance, the factors that must be controlled include: color consistency, the number of inkvoids (which must be kept to a minimum), shrinkage and wrinkles, and fade resistance

in terms of functionality, it is important to control the following factors: size (must be consistent), no adhesion or caking, wear resistance, flattening (no curling) and consistency

now many label buyers require monochrome printing on the back of the label to support some promotional activities. This requirement is also met, and the processing cost is relatively low, because many sheet fed printers have such devices, which can also print color on the back of the label in one printing. If we can continue to make breakthroughs in technology
