Thermoplastics are used in various applications, including PP, PS, ABS, copolyester, SAN, PC etc.. For example, a TPE that can bond to PC does not bond to PP, vice versa. The failure mode is cohesive on PP and adhesive on all other substrates.

There is also a shift from polypropylene (PP) to high-density polyethylene (HDPE) closures, where post-consumer resin is more readily available. Injection and fill pressures will be different with PCR versus virgin resin due to viscosity inconsistencies of the PCR
