Start date (scheduled), etc.
・1991: Developed Japan’s first heat labeling system
Explanation of technologies and business models
Tack labels, to which a glue agent is applied in advance, are utilized by removing the labels from the label release paper during the process of attaching the labels to the products, and the release paper portion is no longer needed. The amount of release paper used by the entire domestic manufacturing industry is said to amount to 116 million m2 per month, most of which is disposed of or incinerated without being recovered or reused as a resource.
We have developed a heat label that uses a heat-sensitive adhesive method that does not require release paper, even though it is pre-applied with a glue, thereby eliminating the need for release paper itself, which accounts for about 40% of the entire label.
By proposing solutions to reduce the use of product resources from the design stage and solve the issues faced by stakeholders at each stage, we are working with our customers to reduce waste and costs incurred during the production of release paper, eliminate waste (label release paper) generated after label application, improve work efficiency during production, and support resource recycling after use.
Achievements and goals, etc.
Wide range of glues: Strong adhesion, easy peeling at room temperature, water immersion peeling, alkali peeling
⇒ Easy access to resource recycling by designing glues according to usage environment and recycling applications after use.
・Strong adhesion : It will not peel off even under various environments. If an intentional attempt is made to remove the label, it will tear and leave a trace on the container, thus preventing tampering.
・ Easy peeling at room temperature : The label can be easily peeled off by hand. (Types with/without adhesive residue are available.)
・ Water immersion peeling : The label can be easily peeled off by immersing it in water. The label will be torn if it is intentionally peeled off during the distribution process.
・ Alkali peeling : The label can be easily peeled off during the bottle washing process at the customer’s factory so that the bottle can be reused.The label will be torn if it is intentionally peeled off during the distribution process or by immersing it in water.
Industries where the product is used: Beverage industry, pharmaceutical industry, food industry, etc.
