Moulded pulp fibers for disposable food packaging: A state-of-the-art review KATHERINE E. SEMPLE 1 , CHENLI ZHOU 1 , ORLANDO J. ROJAS 2 , WILLIAM NGUEGANG NKEUWA 1,3 , CHUNPING DAI 1 . The paper provides a comprehensive review of moulded pulp production, properties and advantages over single-use plastics and bioplastics for food packaging. Bagasse, wheat and bamboo are replacing wood as the fiber sources due to their cost effectiveness, wide availability and rapid renewability. Non-wood pulping and thermoforming processes have also advanced greatly which lead to improved fiber recovery, production efficiency and product quality. Challenges include lengthy production cycles, high chemical and energy uses, competition from bioplastics, and presence of toxic per-and poly-fluoroalkyl substances (PFAS). The industry is evolving rapidly to overcome these challenges including new laminated dry thermoforming processes, natural additives, customized fiber mixes, and PFAS-free products. Life-cycle assessments and provision of clear, viable green waste and recycling pathways relative to plastic alternatives are still needed to establish and maintain the competitiveness of cellulosic bioproducts with plastics. Critical research areas are proposed.

The Paper Industry Technical Association (PITA) is an independent organisation which operates for the general benefit of its members – both individual and corporate – dedicated to promoting and improving the technical and scientific knowledge of those working in the UK pulp and paper industry. Formed in 1960, it serves the Industry, both manufacturers and suppliers, by providing a forum for members to meet and network; it organises visits, conferences and training seminars that cover all aspects of papermaking science. It also publishes the prestigious journal Paper Technology International ® and the PITA Annual Review , both sent free to members, and a range of other technical publications which include conference proceedings and the acclaimed Essential Guide to Aqueous Coating .
