A labeling system for use with containers, comprising at least one linerless label, wherein the at least one linerless label is adapted to receive printing thereon; a substrate for receiving the label and to which the label becomes permanently bound after the label has been attached to the substrate; a first adhesive, wherein the first adhesive is a repositionable adhesive; a second adhesive, wherein the second adhesive is a remoistenable adhesive that includes predetermined amounts of polyvinyl alcohol, dextrin, and at least one humectant, and wherein the adhesives are deposited on the label prior to attaching the label to the substrate.

Provided are a label, a top layer material formed on a printing medium, an information-bearing medium, a solid fuel and a wristband clip having the function of absorbing carbon dioxide, and carbon dioxide reduction methods using the same. Provided are labels 101, 120, 130 and 140, top layer materials formed on a printing medium 201, 246 and 266, information-bearing media 301, 330, 350 and 360, a solid fuel 401, and a wristband clip 510, to which a new carbon dioxide absorbent is added. Provided are also carbon dioxide reduction methods of absorbing carbon dioxide by burning the same.

A light-blocking label configured to be affixed to an article made of a polymeric material such as polyethylene terephthalate (PET), high density polyethylene (HDPE), other similar polymeric materials, or some combination thereof. The light-blocking label includes a light-blocking ink layer that may be reverse printed onto the label substrate while other ink layers (e.g., white ink layer, color ink layer) may be surface printed on the label substrate. The light-blocking label may also include an optional varnish and/or adhesive layer. In some embodiments, the label substrate and article comprise PET and are configured to be collected as recycled PET (i.e., a recyclable light blocking label). In such an embodiment, the one or more ink layers and optional layers in the light-blocking may be configured to be removed prior to collection of the light-blocking label as recycled PET.
