For manufacturers of sensitive food and pharmaceutical products, every detail matters. Packaging must reliably protect against oxygen, water vapor, and aroma loss, while meeting increasing demands for material efficiency and recyclability. Paper provides an attractive foundation, but it often reaches its functional limits.
At Fraunhofer IVV, we are therefore developing a transfer process in which inorganic barrier layers are transferred onto fiber-based substrates. This enables high-performance barrier packaging and opens up new opportunities to reduce conventional multilayer composite structures. The principle is simple: the barrier layer is first deposited onto a reusable carrier film and then transferred to the paper substrate. This approach can be integrated into existing production environments. Together with industry partners, we are bringing this barrier transfer technology into practice: One industrial partner has already produced initial samples using our technology, which are currently being evaluated. In parallel, we are assessing several thousand meters of transfer-metallized barrier paper under real production conditions. Through the "IMPACT" project, we are advancing the technology within an international consortium.
