Shrink wrap labels for shaped articles
Methods for applying high shrink wrap labels to a shaped article are disclosed. The leading edge of the label is bonded to the article. A seaming agent is applied, and the label is wrapped around the article. The seaming agent is then exposed to radiation to cure the seaming agent, and the label is then exposed to heat to cause heat-shrinking. The label is made of a film with at least one external layer that has a Hildebrand solubility parameter. The seaming agent includes a component having a Hildebrand solubility parameter that is within 2.2 MPa.sup.1/2 or within 4.4 calories.sup.1/2.Math.cm.sup.3/2 of the Hildebrand solubility parameter of the external layer of the film. The seaming agent also has a viscosity of at least 1 centipoise and less than 1000 centipoise when measured at any temperature between ambient temperature and 60 C. Articles including such affixed high shrink wrap labels are also disclosed.
Multiple wrap label
A multiple wrap label has a first wrap portion extending from a first end and having a first width, and a second wrap portion extending from the first wrap portion to a second end, the second wrap portion having a second width greater than the first width, the second wrap portion extending over and enclosing the first wrap portion when the label is applied to a container.
Sealing label and snuff container with a sealing label
A sealing label for sealing a snuff container may include a structural layer and having first and second side edges extending in a length direction and first and second end edges extending in a width direction. The sealing label may be divided in the width direction into a container lid attachment area and a container base attachment area. A tear strip area may be arranged between the container lid attachment area and the container base attachment area and may be terminated by a pull tab arranged at the first end edge. The structural layer of the sealing label may be a single structural layer of the sealing label and may consist of a mono oriented polymer film having a direction of orientation coinciding with the length direction of the sealing label. A snuff container provided with the sealing label is also disclosed.
SHRINK WRAP LABELS FOR SHAPED ARTICLES

The seaming agent is then exposed to radiation to cure the seaming agent, and the label is then exposed to heat to cause heat-shrinking. The label is made of a film with at least one external layer that has a Hildebrand solubility parameter. The seaming agent includes a component having a Hildebrand solubility parameter that is within 2.2 MPa.sup.1/2 or within 4.4 calories.sup.1/2.Math.cm.sup.3/2 of the Hildebrand solubility parameter of the external layer of the film. The seaming agent also has a viscosity of at least 1 centipoise and less than 1000 centipoise when measured at any temperature between ambient temperature and 60 C. Articles including such affixed high shrink wrap labels are also disclosed.
Heat-shrinkable polyester film having longitudinal (lengthwise) direction as main shrinkage direction
[Problem] To provide a heat-shrinkable polyester film having excellent shrink finishing property due to the film's sufficient heat shrinkability and low shrinkage stress in the longitudinal direction, small change in the non-shrinkable direction of the film. [Solution] The heat-shrinkable polyester film which heat-shrinks in the longitudinal direction and satisfying the following (1) to (6); (1) having a shrinkage of 35% to 70% in the longitudinal direction; (2) having a shrinkage of 8% to 7% in the width direction; (3) having a change rate of 5% to 22% when fixed in the longitudinal direction with fixed-length; (4) having a change rate of 5% to 20% in the width direction when fixed with 10% of slack in the longitudinal direction; (5) having a maximum shrinkage stress of 5 MPa to 15 MPa in the longitudinal direction; (6) having a stress at 10% elongation, F10, of 1 MPa to 5 MPa in the longitudinal direction and 0.5 MPa to 3 MPa in the width direction.
Label applicator belt system
A label applicator system is described comprising one or more, and preferably two, assemblies of rollers and belts. The assemblies are arranged relative to one another such that at least a portion of the belts of each assembly are aligned with one another to define an article receiving lane. The assemblies are arranged and configured such that the lane extends in a zig- zag path, a relatively straight path, and/or an arcuate path. Selection of the lane geometry along with appropriate control of belt velocities enable high rates of applying labels to articles and particularly containers having compound curves.
