Meanwhile, toilet paper, kitchen towels and facial tissues, combined make up 85.2% of all tissue paper products consumed in 2018. While different factors can be named as responsible for this growth in consumption, it is quite difficult to isolate the product-related factors that contribute to the growth of consumption of tissue paper in different countries due to the fact that tissue products have limited uniform specifications between different suppliers. This means, tissue suppliers and tissue machine manufacturers, like Valmet, are left with the challenge of understanding customers’ motivations behind demand of different tissue paper products. This is the motivation behind this study, which is to investigate what qualities of toilet paper, facial tissues and kitchen towels, are customers in the US, China and Japan satisfied or dissatisfied with. This is compared with measurements of the qualities of these products, like softness, strength, thickness, to determine the ranges of values of the products’ qualities that customers are satisfied with. Online reviews of 34 different brands of tissue paper products are collected ethically from online retailer websites (Amazon US, Amazon Japan, Walmart, JD.com), and analysed using the thematic analysis methodology to identify the list of qualities of tissue products that customers are satisfied or dissatisfied with. Then, the Pareto rule was used to identify the top 20% most important qualities to customers. These 34 brands were also purchased from these online retailers and their different qualities were measured. The results and conclusion from the study revealed different insights, among which is that softness is a must-be quality for toilet papers in all countries studied, while water absorption is a must-be quality for kitchen towels. The study also revealed ranges of the numerical values of these qualities that are acceptable to end consumers. Valmet intends to use the conclusions from the study in engagements with tissue paper suppliers in the three countries regarding product strategies and choice of technology. Keywords: Perceived Quality, Customer Satisfaction, Thematic Analysis, Tissue Paper Acknowledgements We would like to extend our gratitude to the wonderful staff at Valmet, who, out of their busy schedules, created time for us during the entire period of the thesis. Special thanks to Hannes Rask, our supervisor at the company for his support from the beginning to the end of the thesis. Ingmar Andersson, also deserves a mention for the leadership provided and support in accessing the required resources needed in carrying out the thesis. Carina Törngren at the Tissue Technology Center was also very supportive with providing us measurement results on time, and your support was instrumental in the completion of this work. We also appreciate Agnes Lindell who was the one that motivated our decision to take up this thesis topic, and she was very supportive throughout the entire thesis work. We also appreciate our supervisor at the university, Magnus Berglund, who out of his experience as an accomplished researcher, provided us the required guidance and support in writing this thesis. We also thank our opponent, Hassan Makaraan, for his insightful inputs to our thesis work. This publication is part of Mobolaji’s research work produced during his scholarship period, funded by the Swedish Institute at Linköping University. Table of Contents 1.
