Comparative Analysis of the Effects of Incorporating Post-Industrial Recycled LLDPE and Post-Consumer PE in Films: Macrostructural and Microstructural Perspectives in the Packaging Industry.

Additionally, the crystallinity of rLLDPE decreases with recycling, while rPEpostc does not exhibit a clear trend, likely due to its initially low degree of crystallinity.

The same trend is observed for rLLDPE for tear strength in the transverse direction, where the values show a decreasing trend, albeit at a slower pace, decreasing from 290 to 187 N/mm (−35%).
