Abstract
Label assemblies and methods of manufacturing label assemblies are described. In an aspect, a thermal sheet includes a post-consumer waste (PCW) paper layer and a thermal coating applied at a side of the post-consumer waste paper layer. The post-consumer waste paper layer may have a fiber density that allows the thermal coating to sit on the side of the post-consumer waste paper layer while reducing absorption of the thermal coating within the post-consumer waste paper layer.
Claims18
A thermal sheet comprising:
- a post-consumer waste (PCW) paper layer;
- and
- a thermal coating applied at a side of the post-consumer waste paper layer, wherein the post-consumer waste paper layer has a fiber density of between 30 and 150 grams per square meter to reduce absorption of the thermal coating within the post-consumer waste paper layer.
A method of preparing a thermal sheet, the method comprising:
- providing a post-consumer waste (PCW) paper layer;
- and
- applying a thermal coating at a side of the PCW paper layer, wherein the PCW paper layer has a fiber density of between 30 and 150 grams per square meter to reduce absorption of the thermal coating within the post-consumer waste paper layer.
