artience group 's TOYO INK CO., LTD. (Hideki Yasuda, Chuo-ku, Tokyo, President and Representative Director) conducted a demonstration test of horizontal recycling, in which multilayer monomaterial packaging is stripped off and recycled into a highly transparent film, and confirmed that the physical property evaluation results of the film using 30% recycled material are of a practical level.
In this demonstration test, Lipton Tea & Infusion Japan Co., Ltd., TOPPAN Co., Ltd., and TOYO INK developed a multilayer monomaterial package that can be reel-and-white, and Futamura Chemical Co., Ltd. molded the film using recycled materials and evaluated its physical properties.

Many film packages have a multi-layer structure using printing inks and adhesives between films made of different materials, such as polyolefins and polyesters. While this combination of different materials enables package designs to ensure different performance requirements for different applications, the difficulty of recycling increases the need for mono-material packaging made of a single material.
The prototype multilayer PP monomaterial package that can be exfoliated is equipped with the necessary performance as a packaging material, such as the barrier properties of oxygen and water vapor, and consists of TOYO INK peeling laminating adhesives and deinking coating. By alkali-treating this package, peeling off the film, and debonding off the printed ink, it is possible to extract high-quality recycled materials with high transparency and few impurities.

In addition, we are studying so-called horizontal recycling, in which recycled pellets are used as film raw materials and returned to the original film, and we have confirmed that the physical properties of biaxially oriented polypropylene film (OPP) using 30% recycled pellets are of a practical level of quality.

As a leading company in packaging inks and laminating adhesives, artience group is verifying the practical application of plastic recycling, including film packaging, from both the materials and processes involved in recycling. In order to promote recycling, it is necessary for society as a whole to work beyond the boundaries of industries, and by expanding the circle of collaboration with partners in a wide range of fields, such as brand owners, converters, film manufacturers, machine manufacturers, and recyclers, we will contribute to the construction of a recycling system and the realization of a recycling-oriented society.
