INTRODUCTION
The invention relates to die cut or patch metallized labels for use with
cold glue, and to films for making such labels. According to the
specification, cold glue adhesives are widely used for application of labels to
containers. Specification, para. [0004]. The labels are generally multi-layer
structures as shown, for example, in Figure 1.
Claims 1 and 4 are illustrative:
1. A metallized thermoplastic label comprising:
(a) a first skin layer comprising a thermoplastic and a first cavitating
agent, wherein the first skin layer has a first side and a second side, the first
skin layer is cavitated, and the first side of the first skin layer is adapted to
be used in contact with a cold glue adhesive;
(b) a core layer comprising polypropylene and a second cavitating
agent, wherein the core layer has a first side and a second side, and the first
side of the core layer is adjacent to the second side of the first skin layer; and
(c) a second skin layer comprising polypropylene, wherein the second
skin layer has a first side and a second side, the first side of the second skin
layer is adjacent to the second side of the core layer, and the second side is
metallized,
wherein said second cavitating agent has a median particle size of 1.5
microns or less and said metallized surface has a bright mirrored appearance.
4. A metallized thermoplastic label comprising:
(a) a first skin layer comprising a thermoplastic and a first cavitating
agent, wherein the first skin layer has a first side and a second side, the first
skin layer is cavitated, and the first side of the first skin layer is adapted to
