  1. aThe size of injection and film samples was 60 × 10 × 3 mm and 150 × 10 × 0.5 mm, respectively
  2. bBoth CNFs were the type of cellulose nanofibril in ISO/TS 21,346:2021 [19]
  3. cThe number of samples for each CNF addition ratio was shown. Within the parenthesis was shown the number of each sample set for quantitative analysis
