Teijin develops wet-strong printing paper from 100% recycled polyester
Teijin’s ECOPET recycled polyester fiber is used in a wide range of products, including apparel, uniforms, interior items such as curtains and carpets, industrial materials such as tents, banners and filters, and civil engineering materials. It develops the paper in collaboration with Nisshinbo Postal Chemical Co, Ltd.
According to Teijin, the new printing paper is as thin as conventional printing paper. It can be used normally in regular laser printers with no need for manual feed. Also, unlike conventional water-resistant printing paper made of film, the paper enables easy scoring, gluing and writing with pens or pencils.
Besides, as a wet laid nonwoven fabric made with the same method as machine-made Japanese paper, it offers levels of flexibility and texture not achievable with film-based printing paper.
As a polyester material, the printing paper is highly water resistant compared to conventional pulp-derived paper and is not easily torn when wet, making it ideal for use in outdoor or wet locations. Potential applications include hazard maps, triage tags and other outdoor or disaster supplies, outdoor posters, recording papers, and labels and price tags for fresh or frozen foods.
Nisshinbo Postal Chemical Co, Ltd. will handle sales limited to Japan through trading companies and printer makers. Teijin has some 150 companies and around 17,000 employees spread out over 20 countries worldwide. Its main fields of operation are high-performance fibers such as aramid, carbon fibers & composites, healthcare, films, resin & plastic processing, polyester fibers, products converting and IT.
