The stretching temperature exhibits pronounced effects on the structure and puncture resistance of the crosslinked polyethylene films. The image by Rong Wang and colleagues show 2D XRD of the films stretched below and above melting temperature. Due to the formation of crosslinks or bridges between the macromolecular chains of XL‐HDPE, it exhibits a viscoelastic behavior but no free flow of melt with macromolecules being confined, resulting in the high orientation of macromolecular chains even though the stretching temperatures reached above T m . Combination of the results of DSC, 1D XRD, and SEM allowed the relationship between morphologies and puncture properties to also be discussed. DOI: 10.1002/app.47542 .
