For a resource-recycling society, we developed a container for “SOFLAN Premium Deodorizer”, a fabric softener, with the aim of reducing the use of petrochemical-derived plastics. Recycled plastic (PCR: post-consumer recycled resin) obtained from beverage caps collected in Japan was selected as the bottle material. When beverage cap, injection molded products is used in a blow-molded bottle, the difference in plastic properties becomes an issue. Therefore, by mixing beverage caps (high MFR) with other plastics (low MFR), we succeeded in converting them to a property suitable for bottle molding. This technology has reduced the use of petroleum-derived plastics in bottles by more than 60%.
In addition, the cap is smaller and lighter than the existing caps, reducing the amount of plastic used by about 35%. The development of these new technologies are expected to accelerate the introduction of recycled plastic into our other products and reduce the amount of plastics.

To convert the beverage cap into properties suitable for bottle molding, we utilized another recycled plastic. However, when the crushed beverage cap was mixed with the recycled plastic for conditioning, a large deviation in MFR occurred within the same lot. This was thought to be caused by the lack of uniformity between the two materials during mixing. By reducing the size difference between the two materials before mixing and optimizing the mixing method, the MFR deviation within the same lot was successfully reduced significantly.
In addition, by reducing the number of screw rolls, simplifying the cap while maintaining usability, and reducing its diameter, the amount of plastic used in the cap as a whole was reduced by approximately 35% compared to the conventional product. “SOFLAN Premium Deodorizer” container is an environmentally friendly container that not only uses PCR material but also reduces the amount of plastic used.
