What is Multi-layer Plastic?

Multi-layer plastic combines multiple polymers or barrier layers in films, pouches, sachets, and laminated structures.

Common uses

PouchesSachetsBarrier filmsRefill packs

EPR Classification

Use when the package includes multiple plastic layers or barrier materials that prevent single-resin classification.

Recyclability: Multi-layer flexible packaging is often not mechanically recyclable in curbside systems.

Recycled content: Recycled content claims are uncommon and should be supported by layer-by-layer specs.

Common Packaging Formats

Format	Typical weight	Common products
Pouch	5-25g	Refills and food products
Sachet	0.5-4g	Samples and single-use products

How to Document Multi-layer Plastic

• 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.

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