Abstract
An insulating label stock includes a thermal insulating layer, which may a fiberfill batt. The batt is laminated to at least one layer of film, paper or fabric. The label stock can be wrapped around a container, such as a can, bottle or pouch. The label stock may be coated with a coating material so that it is printable, thus imparting both insulating properties and print capability to a container.
Claims19
An insulating label stock, comprising a thermal insulating layer wherein the label stock is at least 0.0075 inch thick;
- the thermal insulating layer has a thermal resistance in the range of 0.05 to 0.5 CLO (0.0077 to 0.077 m2*K/W) and laminated directly to a face material;
- the face material is a single sheet having a first layer and a second layer;
- and the second layer has a lower melting temperature than the first layer.
An insulating label, comprising a thermal insulating layer having a thermal resistance in the range of 0.05 to 0.5 CLO (0.0077 to 0.077 m2*K/W) which is laminated directly between two sheets of face material, wherein the label has a top edge, a bottom edge, and a side edge disposed at each side between the top and the bottom edge, and the two sheets of face material are sealed together along the top, bottom and side edges so that fluid cannot penetrate the edges of the insulating label.
An insulating label stock, comprising:
- a) a thermal insulating layer having a thermal resistance in the range of 0.05 to 0.5 CLO (0.0077 to 0.077 m2*K/W);
- b) a face material, the thermal insulating layer being directly laminated to the face material, the face material comprising a first sheet of biaxially oriented polyester film comprising a first layer and a second layer disposed on one side of the thermal insulating layer, and a second sheet of biaxially oriented polyester film comprising a first layer and a second layer disposed on the other side of the thermal insulating layer, wherein the label stock has a top edge and a bottom edge, and the first and second sheets of biaxially oriented polyester film are sealed together along the top and bottom edges, so that fluid cannot penetrate the top and bottom edges of the insulating label stock, and further wherein the label stock has a thickness greater 0.0075 inch (0.0190 cm).
An insulating label stock, comprising:
- a) a thermal insulating layer selected from the group consisting of a fiberfill batt, melt blown fibers, knit fabric, woven material, and fleece;
- said thermal insulating layer having a thermal resistance in the range of 0.05 to 0.5 CLO (0.0077 to 0.077 m2*K/W);
- and b) a face material, the thermal insulating layer being directly laminated to the face material, the face material comprising a first sheet of biaxially oriented polyester film comprising a first layer and a second layer disposed on one side of the thermal insulating layer, and a second sheet of biaxially oriented polyester film comprising a first layer and a second layer disposed on the other side of the thermal insulating layer.
