Heat shrinkable film label is a 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 follow the outer contour of the container Shrinkable, close to the container surface, heat shrinkable film labels mainly include shrink sleeve labels and shrink wrap labels. Shrink sleeve labels are made of heat-shrinkable film as the base material, and are made into cylindrical labels after printing. It has the characteristics of convenient use and is very suitable for special-shaped containers. Shrink sleeve type labels generally require special labeling equipment to cover the printed sleeve onto the container.
First, the labeling equipment opens the sealed cylindrical sleeve label, which may sometimes need to be punched; next, the sleeve label is cut to a suitable size and placed on the container; then heat treatment is performed using steam, infrared or hot air channels So that the sleeve label adheres tightly to the surface of the container. Due to the high transparency of the film itself, the label has a bright color and good gloss. However, because it must be shrunk during use, there is a disadvantage of pattern distortion, especially for products printed with barcode labels. Must pass strict design and printing quality control, otherwise the deformed pattern will cause the barcode quality to be unqualified. Shrink wrap labels can be labeled using traditional labeling equipment. Adhesives and higher temperatures are required during the labeling process. During the shrinking process, since the adhesive at the overlapping position of the film will produce stress, it is better to use hot-melt adhesive.
