artience group 's TOYO INK CO., LTD. (President and Representative Director Hideki Yasuda, Chuo-ku, Tokyo) has adopted the debonding and recycling technology of Lion Corporation (Representative Director, President and Executive Officer Masayuki Takemori,Taito-ku, Tokyo) for "Look Plus Bathtub Cleansing Clear Citrus Fragrance Refill Large Size". Products using this technology will be released in limited quantities from November 2024.

Film packaging, called "flexible packaging," has a multi-layer structure to ensure different performance requirements for different applications, but the use of multiple materials such as printing inks and adhesives between plastic films such as polyolefins and polyester has been one of the factors that hinders the high-quality material recycling of packaging.

TOYO INK has developed a technology to recover plastics as a single high-purity material by debonding off films of different materials and removing printing ink from the film, and has repeatedly verified it for social implementation.
By making repeated improvements together with Lion Corporation, we have been able to expand the use of this debonding recycling technology to refill packs. The crushed refill pack is alkalily treated and adhesives is dissolved to debond off the surface film and the polyethylene film to be recycled. Furthermore, by separating the films using the specific gravity difference after debonding, it is possible to recover polyethylene films with high purity.

We aim to collect laminated films that are not used as products, such as offcuts generated during the manufacture of refill packs, and use them again as refill pack films. We are promoting consideration with the goal of launching it within 25 years.

Recycle unused laminated film into refill packs

In order to realize the social implementation of recycling, it is necessary for society as a whole to work beyond the boundaries of industries. TOYO INK will promote the recycling of used plastics and contribute to the realization of a recycling-oriented society toward the realization of a sustainable society by recruiting organizations that can jointly consider the issue not only in the daily necessities industry but also in other industries, and by collaborating with partners in various ways to build a recycling system.
