Hot Melt Adhesive Is Preferred for Shrink Sleeve Labels


    The shrink sleeve labels is a cylindrical label made of heat shrinkable film as the base material and printed. It has the characteristics of convenient use and is extremely suitable for special-shaped containers. Shrink sleeve labels generally require special labeling equipment to cover the shrink sleeve labels onto the container. First of all, the labeling equipment will open the sealed shrink sleeve labels, sometimes it may need to punch holes; Next, cut the sleeve label into appropriate sizes and sleeve it on the container. Then heat treatment is carried out by using steam, infrared rays or hot air channels so that the casing label is tightly attached to the surface of the container.

    Due to the high transparency of the film itself, the label has bright colour and lustre. However, due to shrinkage during use, there is a defect of pattern deformation, especially for products printed with bar code marks. Must go through the strict design and printing quality control, otherwise, the distortion of the pattern will cause unqualified bar code quality. Shrink sleeve labels can be labeled with traditional labeling equipment, and adhesives and higher temperatures are required in the labeling process. In the shrinkage process, hot melt adhesive is preferred because the adhesive at the overlapping part of the film will produce stress effect.
