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.

19th European PLACE Conference highlights challenges of balancing sustainability with product protection, TAPPI Journal July 2025
ABSTRACT: The European PLACE (Polymers, Laminates, Adhesives, Coatings and Extrusion) Committee was founded in 2023 with the goal of continuing a biennial conference for the flexible packaging and converting industry, including converters, OEMs, raw materials suppliers, and academia. Previous iterations of the PLACE Conference were organized by TAPPI, but the new European Place Committee has now found a home within bdvi e.V. (Bund Deutscher Verpackungsingenieure), which is the Association of German Packaging Engineers, a registered nonprofit organization.

Data-efficient determination of machine-specific process windows in thermoforming using the example of PCR materials, TAPPI Journal July 2025
ABSTRACT: In an industrial context, process windows for thermoplastics in thermoforming processes are still often determined through time-consuming trial-and-error approaches. This results in increased effort when commissioning new machines, implementing new technologies, or substituting sheet materials. One key reason is the lack of methods that allow for efficient, process-related assessment of material behavior and a quantitative definition of a “target state” of the heated sheet in relation to geometry and process conditions. In this study, we present the In-Situ Thermoforming Characterization (ITC) method as an application-oriented approach that enables format-independent evaluation of material behavior directly within the forming station of a thermoforming system. The method was successfully applied to a material substitution case, replacing conventional virgin polypropylene (PP) with post-consumer recyclate (PCR) — in this case, recycled PP (rPP) — in the production of a defined cup geometry. The results enabled the transfer of existing process knowledge from the virgin material to the recyclate, thereby accelerating material qualification. Based on the collected data, material behavior under process conditions could be mapped within the design space, making it possible to identify machine settings that deliver equivalent forming results in our test setup. Overall, the method shows strong potential for efficient and precise determination of machine-specific process windows.

Editorial: Investing in Amercian advanced manufacturing, TAPPI Journal June 2025
ABSTRACT: American manufacturing is seeing a renewal, which is needed to boost jobs in America, particularly in the middle and manufacturing base of the country. The ongoing tariff situation emphasizes the importance of protecting domestic manufacturing. There is U.S. congressional agreement, in principle, to bring back manufacturing to the United States. However, given how the global trade and manufacturing space has shifted in the last four decades, it may not be a comparative advantage to manufacture low margin and labor-intensive products. Officials in the current U.S. Administration have stated that manufacturing of socks and T-shirts is not necessarily in the interest of the United States, but focusing on value-added products is essential. While silicon chips, solar panels, and batteries are key items of interest, advanced textile materials such as those that find applications in industrial products and composites, products that can save human lives, and products for protecting the environment are highly-valued items that cater to national security.
