De-Plasticizing Flow of Packaging Materials

Abstract

Rengo first commercialized corrugated packaging in Japan and entered paper manufacturing from early stage. Currently, its business expands to folding carton, flexible packaging, and heavy-duty packaging domestically and internationally, taking SDGs (sustainable development goals)-conscious approach. Since the high economic growth period, when corrugated packaging demand increased dramatically, polystyrene foam is widely utilized to protect products. Meanwhile, from a recycling point of view, various paper cushioning materials are developed, which Rengo also puts effort into. Recently, with the rapid e-commerce expansion, consumers catch more sight of packages delivered by couriers which increased social concern about packaging materials. Rengo focuses on paper-based packaging material development from a de-plasticization perspective and material usage reduction. It developed an auto-size-adjustable packaging system according to contents of the corrugated box, and recyclable packages based on cellophane made of wood pulp featuring high biomass and biodegradability. Rengo continues R & D to contribute to reducing environmental impact and creating a sustainable society.
