Features of heat shrinkable film labels

The characteristics of the heat shrinkable film labelRelease time: 2017-04-28 　　 Heat shrinkable film label is a kind of film label printed on plastic film or plastic tube with special ink. During the labeling process, when heated (about 70℃) , The shrink label will quickly shrink along the outer contour of the container, and stick to the surface of the container. Heat shrinkable film labels mainly include shrink sleeve type labels and shrink wrap labels. Shrink sleeve label is a cylindrical label made of 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. Due to the high transparency of the film itself, 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. Shrink wrap labels can be labeled with traditional labeling equipment, which requires the use of adhesives and higher temperatures 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. Currently, shrink wrap labels are usually made of PP film. Since the shrinkage rate of PP film is not high, generally within 20%, it is more appropriate to use hot melt adhesive when labeling. If a solvent-based adhesive is used, it may cause wrinkles in the PP film. Due to the higher shrinkage temperature of PP film, hot air is mainly used for heat treatment, which can reach a higher temperature than steam heating. Heat-shrinkable film labels are part of the label market and are currently undergoing rapid growth. The market share is constantly expanding. The annual growth rate is expected to be about 15%, which greatly exceeds the annual growth rate of about 5% in the ordinary label market. It has huge development potential. Become a highlight of the label printing industry. http://, heat shrinkable film label Previous: Printing process of heat shrinkable film label
