Technical lignin in alkaline pulping black liquor is usually combusted for energy a soda recovery unit. To improve resource utilization, multiscale nanoparticles (LNPs) were acid precipitated from and combined with gelatinized starch (SS) to produce series of uniformly mixed surface coating agents enhance the barrier properties paper materials including water, oil, water vapor resistance. The 20%SS 50%LNPs (based on oven-dried SS) diameter 276 nm could significantly coated paper. Cobb 60 decreased by 79.6% 67.98 13.86 g/m2, Kit rating improved 0 10, transmission reduced ≥3000 441.69 g/m2·day. presented superior mechanical properties, thermal stability, repulpability, biodegradability. This work provides an effective strategy high-value application holds promise paper-based packaging.
