The changing trend of food packaging labels in the United States

in the United States, IML method is more and more applied, and a wide range of labels with various colors are readily available. The development of UV curing outer coating is only a few examples of changes in the label industry, which outline the future of the label industry

today, 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. Plastic sleeve labels with heat shrinkability are applied to both metal cans and bottles because aniline printing is economical and can meet satisfactory standards

paper and printing

as long as food companies still have gluing and labeling machines, they will still choose paper labels to stick to metal cans and bottles. Such labels are occasionally embossed or ironed with metal foil, giving them unique quality. However, these features also significantly increase costs, and food companies are notoriously unwilling to pay more for their labels that do not smell anything in the air

in recent years, two major changes have taken place in the field of paper labels. 2) input channels: large changes: the first is the demand for UV (ultraviolet) cured coatings, 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 extra cost. Special colors can reduce discoloration. Discoloration often occurs when four-color ink is used to create a special background or field color on the label

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 are:

● color consistency

● the number of inkvoids (which must be kept to a minimum) shrinkage cracks and wrinkles

● 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 labels to support some sales promotion 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
