Disclosed is a multilayered shrink label with a core layer comprising a continuous phase of a watersoluble polymer and one or more skin layers which are printable and solvent seemable.
Problem and Opportunity
Stretch sleeve labels are currently made from films of polyolefins such as linear low-density polyethylene (LLDPE). The film is extruded, printed and then formed into a sleeve by means of seaming. The seaming could be done by the aid of heat sealing or laser welding. Once the sleeve is formed, it is mechanically stretched and placed on a container to become a label. This method of label formation is not suitable for containers with high shrink demand due to limited stretchability and elasticity of polyolefins. In addition, due to the nature of low surface energy of polyethylene, the graphics of the printed label are less than ideal.
Therefore, there remains a need to provide a method of producing a label using a soft printable film and applying said label to complex shaped containers. Said label must also be manufactured using tubing technology (annular die) or even on a miniature blown line.
To overcome these issues, one may construct the sleeve label by tubing.
It is an object of the subject matter of the present invention to provide a label that will offer more coverage than the stretch sleeve labels for containers having complex shapes. It is another object of the subject of the present invention to provide a label that will be made from a material having high stretch and recovery characteristics with soft touch that is printable. The label should preferably be less expensive than a stretch sleeve label as providing a seaming may be avoided. Such label is also aimed to compete with roll-fed shrink (RFS) sleeve labels or shri...
