What is EPS?

Expanded polystyrene is foam packaging used for cushioning, insulated shipping, and protective inserts.

Common uses

Foam insertsCoolersProtective cornersInsulated shippers

EPR Classification

Report foam EPS separately when required; do not combine with rigid polystyrene unless the report format instructs it.

Recyclability: EPS is often restricted or subject to phase-outs; classify accurately and seek alternatives where feasible.

Recycled content: PCR EPS claims should be verified because supply and processing are specialized.

Common Packaging Formats

Format	Typical weight	Common products
Insert	5-60g	Electronics, fragile goods
Insulated shipper	100-500g	Cold-chain products

How to Document EPS

• Ask suppliers for resin type, resin identification code, component weight, PCR percentage, and additives.
• Request separate weights for closures, pumps, liners, labels, and decorations.
• Do not report all plastics as one category; resin-specific classification is usually required.

Often Confused With

PSMolded Fiber

Use supplier source text and evidence files to avoid material misclassification. When the material is uncertain, flag it for review rather than guessing.
