Promoting elimination of waste (release paper), improvement of production efficiency at customers’ factories, and resource recycling support after use with the “Heat Labeling System,” which is a thermal bonding method that does not require release paper!
KOTOBUKI SEIHAN PRINTING CO.,LTD
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.

“Resource recycling of waste materials” <Printed materials that cannot be used as finished products (waste paper)>
KOTOBUKI SEIHAN PRINTING CO.,LTD
In the printing process, registration, color adjustments, and other steps generate printed materials that cannot be used as finished products (waste paper). Waste paper generated at our company is separated according to the type of material used, shredded to prevent customer information from being leaked, and then collected by recycling companies. After being recycled into raw materials at each recycling company, the waste paper is delivered to paper manufacturers, where it is regenerated as new products or as refuse derived fuel (RPF) for making products.

Promoting total solution proposals that accompany customers at each stage with “thermal transfer foil”!
KOTOBUKI SEIHAN PRINTING CO.,LTD
Thermal transfer is a technique in which, by applying heat and pressure to a heat-resistant film with a pattern printed on it, the pattern (ink layer) is instantly applied to the base material (molded product). Normally, in the case of direct printing, the more multicolored the pattern, the greater the increase in base material loss due to printing errors and printing work time, resulting in poor yields and requiring more time for delivery. In the case of hydraulic transfer, not only is a large amount of waste fluid generated after the transfer process, but the process also takes time, resulting in longer time for delivery.

PS Recycle Technology
Sulzer Japan Limited
For pyrolysis of polystyrene, which Sulzer perform with its technology partner VTT, combining the strength of Finland’s strongest research organization with Sulzer’s existing SuRe™ styrene technology. Testing different polystyrene wastes including contaminations of polyethylene and polypropylene has been shown to achieve a 64% yield for styrene monomer. The quality of the monomer is suited to the production of polystyrene in all qualities, including for food packaging applications.
