2

Material Properties

High crystallinity levels give this resin its characteristic stiffness and resistance to moisture. When the 2 is embossed on a part, it tells the recycler that the material is a linear polymer with few branches. This structural regularity allows the molecules to pack closely together and create a dense, durable plastic.

Automated Sorting

Infrared sensors in recovery facilities detect the specific chemical signature of the plastic to separate it from other types. Every piece marked with a 2 is diverted into a dedicated stream to be cleaned and ground into flake.

Production Economics

Recycled flake from these containers can be blended with virgin resin to lower the cost of new parts. Because the properties of 2 are predictable across different batches, manufacturers can use high levels of regrind without losing structural integrity in the finished product. The market for this material remains strong because it can be used in diverse applications such as drainage pipes and plastic lumber.

The consistency of the scrap stream reduces the risk of process variations during injection moulding.
