BASF introduces water-permeable thermoplastic polyamide for use in sausage casings
In the ongoing quest for sustainable solutions, Graphic Packaging International has announced the launch of its PaperSeal Pressed modified atmosphere paperboard tray. This innovative product reduces plastic content by a staggering 85% compared to conventional alternatives, making it a significant step towards a more eco-friendly future. Moreover, the PaperSeal Pressed tray is designed with end-of-life recyclability in mind, aligning with the growing emphasis on packaging sustainability.
Meanwhile, in the meat industry, the use of Ultramid H33 L thermoplastic polyamide for thin-walled smoke and drying applications is gaining traction. However, specific companies employing this material are not publicly disclosed. Developed by BASF, Ultramid H opens up new fields of application that were previously beyond technical capabilities.
One such application is the use of Ultramid H33 L in artificial sausage casings. This high-water permeable polyamide allows smoke aromas to pass through during the smoking process and facilitates subsequent drying directly in the casing. Its strength also enables the production of thinner casing walls, contributing to a more sustainable product overall.
BASF has also introduced Ultramid H, a material designed for use in artificial sausage casings, in collaboration with packaging film supplier SÜDPACK and food service company Werz. This collaboration, which took place in April, aimed to utilise BASF's polyamide Ultramid Ccycled material for meat and sausage packaging in the hotel, restaurant, and catering sector.
As we look towards 2025, packaging sustainability is a topic of extensive discussion. The Packaging and Packaging Waste Regulation in 2025 is the focus of an ultimate guide, while another article delves into the key factors for increasing the use of reusable packaging in supermarkets. Top brands' progress on packaging sustainability is also covered in a separate article.
In the broader context of global packaging sustainability regulation, the high-barrier packaging film, manufactured according to the current German minimum standard, is rated as recyclable in the polyethylene film stream. This underscores the importance of adhering to strict standards in the development and implementation of sustainable packaging solutions.
Dr. Rolf Minkwitz, responsible for polyamide product development at BASF, explains that Ultramid H can be processed like any other polyamide. This ease of use, coupled with its numerous benefits, makes Ultramid H33 L a promising material for the future of sustainable packaging.
As the world continues to grapple with the challenges of waste management and environmental conservation, innovations like these offer a glimmer of hope. By reducing plastic content, enhancing recyclability, and finding new, sustainable applications for materials, companies like BASF are leading the charge towards a more sustainable future for packaging.
