Abstract :This study investigates packaging papers produced from recycled wastepaper in terms of oil resistance and mechanical performance, especially for fast food applications. Five different polymers known for their compatibility with paper substrates and oil barrier properties were applied to the paper surface using a laboratory-scale size press. Oil resistance was evaluated using the TAPPI T559 kit test method, and mechanical strength was measured through standard tensile strength and SCT (short-span compression test) methods. Polymers D and E exhibited excellent oil barrier properties, with minimal permeation (4 mm) after 12 hours, while also maintaining strong SCT performance (up to 2.275 kN/m). In contrast, although polymers A and B were less effective in oil resistance, polymer A demonstrated outstanding tensile strength (2355 Nm/kg), making it a suitable option for applications requiring high mechanical strength. The findings suggest that polymers D and E are ideal for long-term barrier applications, whereas polymer A is more suitable where mechanical durability is prioritized. The study emphasizes the need for further research on polymer formulations, particularly bio-based and eco-friendly alternatives, to support the development of sustainable and high-performance paper-based packaging materials.
