The SPE film based on corn starch was doped with different weight percentages (wt%) of NaHSO</span></span><sub><span style="font-family: Times New Roman, serif;"><span lang="en-US">3 </span></span></sub><span style="font-family: Times New Roman, serif;"><span lang="en-US">and prepared using a solution casting method. The SPE was tested by using the Tensile Analyzer to determine the tensile strength and Young’s modulus value.
