Abstract: The combination of polyvinyl alcohol (PVOH) and starch composites leads to the production of biodegradable polymer composites. This polymer compound has good qualities for being used as a biodegradable material, which makes it easier to stop the buildup of synthetic substances made from petroleum. This study is intended to analyse the processability characteristics of PVOH-starch composites using actual injection moulding. The processability study of PVOH-starch found that the compound could be injection moulded. The name tag product (NTP) was used as a product outcome during the injection moulding. The verification of the optimisation was conducted by means of statistical analysis employing full-factorial design methodologies. In short, the statistical results have indicated that optimal processing techniques can contribute to the production of NTP with little volumetric shrinkage (as observed in short-shot scenarios) while maintaining acceptable levels of variability. Finally, the optimum injection moulding process parameters were found at 200°C and a pressure of 90 bar. This is because the NTP was produced at the lowest variation of the NTP’s total weight in this set of parameters.
