What is a roll label?
A roll label is a type of label that is coated with hot melts pressure sensitive adhesives on both ends and wrapped around a container.
hot melts pressure sensitive adhesives is melted using a special labeler and applied in-line.

Other common labels
| adhesive labels | The most common label. There are two types: solvent-based and water-based. Paste while peeling off the release paper. It can be easily applied to substrates, and the labeler is inexpensive and easy to use. |
|---|---|
| shrink labels | Used in perforated PET bottle drinks, etc. After a cylindrical label is placed on a bottle, it is heated with water vapor to shrink the label and wrap it around the container. Can be used with irregularly shaped containers and has excellent design. |
| glue label | Used on beer bottle labels, etc. A label that is attached to a paper label by applying glue dissolved in water. There is less waste and the glue is relatively inexpensive. |
Advantages of roll labels
In the past, labels prioritized design as the face of the product, and were required to be large, easy to read, and not peel off from the container.
However, the functions required of labels from the perspective of global environmental conservation are changing, and roll labels have the advantage of reducing environmental impact.
New functions required for labels
CO2 emissions and performance comparison by label
When we calculated CO 2 emissions for each type of label using CFP, we found that the CFP value for roll labels was lower than for other labels. Roll labels keep carbon dioxide emissions low by making the labels thinner and eliminating release paper.

What is CFP (carbon footprint)?
The amount of greenhouse gases emitted throughout the life cycle of a product or service, from procurement of raw materials to production, distribution, sales, use, disposal, and recycling, is converted into carbon dioxide and easily understood for the product or service. The display mechanism
