Error in Table
In the original publication [1], there was a mistake in the legend for Table 4: Summary of bending characteristic-values of EPC, EPP and EPET at 25, 80 and 110 °C. There is a copy and paste error. In the EPC 110 °C column, the values need to be (top to bottom) 61.0 ± 2.2; 1.4 ± 0.10; 9.5 ± 0.5; 7.7 ± 0.6. The correct legend appears below. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. The original publication has also been updated.
