The role of heat shrinkable labels

The function and characteristics of the heat shrinkable labelRelease time: 2018-01-29 　　 Heat shrinkable label is a kind of film label printed on plastic film or plastic tube with special ink. ), the heat-shrinkable label will quickly shrink along the outer contour of the container and stick to the surface of the container. The heat-shrinkable film labels mainly include sleeve-type heat-shrinkable labels and surrounding heat-shrinkable labels.　　 Shrink sleeve label is a cylindrical heat shrinkable label made with heat shrinkable film as the base material after printing. It is easy to use and is very suitable for special-shaped containers. Shrink sleeve labels generally require special labeling equipment to cover the printed sleeve on the container. First, the labeling equipment opens the sealed cylindrical sleeve label, which may sometimes need to be punched; then, the sleeve label is cut into a suitable size and sleeved on the container; then heat treatment is performed using steam, infrared or hot air channels , Make the sleeve label tightly attached to the surface of the container.　　Because the film itself has high transparency, the label has bright color and good gloss. However, because it must be shrunk during use, there is a disadvantage of pattern deformation, especially for products with printed barcodes. Must go through strict design and printing quality control, otherwise the bar code quality will be unqualified after the pattern is deformed. Surrounding heat shrinkable labels can be labeled with traditional labeling equipment, and adhesives and higher temperatures are required during the labeling process. In the shrinking process, since the adhesive at the overlapping part of the film will produce stress, it is better to use hot melt adhesive.
