There is also a shift from polypropylene (PP) to high-density polyethylene (HDPE) closures, where post-consumer resin is more readily available.

Specialized chemistries enable TPEs to adhere to many different plastic substrates, including polypropylene (PP), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), PC/ABS, copolyester, polyamide, and polystyrene, for a seamless and permanent bond.

These monomers
are then polymerized into chains called polymers, or plastic resin, such as polyethylene and
polypropylene, in their most basic forms.
The major types of thermoplastics include polyethylene,
polyvinyl chloride, polypropylene, polystyrene, polyester and a range of specialized engineering resins.

The coloration of biodegradable polymers—such
as PLA, PHA, PBAT or blends—requires a careful
selection of pigments that must comply with strict
environmental standards.
