Four technologies poised to disrupt the specialty paper market
In its latest research, Smithers Pira has identified four novel technologies that are set to increase capacity and enable new product opportunities for manufacturers of specialty papers across the next five years. The new report—The Future of Speciality Papers to 2022—provides a comprehensive overview of this important sector of the paper industry. It incorporates both higher volume applications, like flexible packaging and label stocks, and more niche segments like electrical insulation, filtration, and security papers.

Editorial: Design considerations for developing high-quality flexible packaging laminates, TAPPI Journal July 2025
ABSTRACT: The global flexible packaging industry has constantly evolved by developing new materials, film design, polymer processing techniques, and machinery to overcome challenges posed by consumer demands, regulation, and societal pressure. While achieving superior quality and improved mechanical film attributes has always been the cornerstone for new technical developments in this industry, the end-of life shortcoming for most plastic films has driven the value chain to strive harder to design and develop sustainable packaging structures.

Adhesion with purpose: The value of primers in sustainable flexible packaging, TAPPI Journal July 2025
ABSTRACT: Primers play a crucial role in flexible packaging by providing adhesion, enhancing performance, and improving the overall quality of packaging structures. As the packaging industry shifts towards more sustainable solutions, it brings new challenges for meeting adhesion requirements. Different types of sustainable materials, with their complicated physical and chemical properties, usually result in poor adhesion in extrusion coating or extrusion lamination, whether this is due to fast crystallization, secondary crystallization, low processing temperature, lack of functional groups, or a combination thereof. Water-based primers ensure that these innovations meet both functional and environmental standards for the packaging of tomorrow. Conventional water-based primers, including polyethyleneimine (PEI) and ethylene acrylic acid (EAA), offer significant advantages in sustainable packaging design by chemically modifying the surface of the substrate to enhance adhesion. In this study, we will discuss adhesion issues in three case studies involving sustainable packaging materials: (1) extrusion coating of polyvinyl alcohol (PVOH) on paper; (2) extrusion lamination of paper and metallized film with starch biopolymer; and (3) extrusion coating of polyhydroxyalkanoates (PHA) on paper. These cases represent three adhesion challenges related to sustainable materials, namely fast crystallization rate, low processing temperature, and secondary crystallization. A three-step adhesion improvement procedure was employed to identify the proper primer in each case study. This procedure included a wetting-out test with primer, an adhesion test, and an extrusion test with priming. In our results, strong fiber tearing or destructive bonds were achieved in each case with the help of water-based primers. These results demonstrate the value of water-based primers in enabling the transition to more sustainable packaging structures without compromising performance.
