Performance Evaluation of Compression‐Molded Recycled Mixed Plastic Fractions From Light Packaging

Polymer Engineering &Science, EarlyView.
Mixed HDPE/PP bottle‐cap waste was successfully processed through closed‐loop mechanical recycling. The recycled blends maintained stable thermal, rheological, and mechanical performance over multiple cycles, demonstrating the feasibility of valorizing heterogeneous polyolefin waste without advanced polymer separation.

Effect of Coupling Agent on the Dispersion of PETG Montmorillonite Nanocomposite films.

, 2003
Polyethylene terephthalate glycol (PETG) is a clear amorphous polymer, which is extensively used in flexible packaging. The dual packaging requirements of recyclability and long-term shelf life are often difficult to achieve.

Process‐Structure‐Morphing Coupling in Thermally Activated ABS 4D Printing

Polymer Engineering &Science, EarlyView.
Graphical abstract illustrating thermally induced shape morphing in FDM‐printed ABS beams. ABSTRACT Predictable thermally induced morphing in fused deposition modeled thermoplastics remains difficult because the deformation response is highly sensitive to processing and activation conditions.
