EPR Classification

Report as LDPE or #4 plastic when supplier documents state low-density polyethylene.

Recyclability: Store-drop-off and film recycling rules vary; small or contaminated flexible packaging is often not curbside recyclable.

Recycled content: PCR LDPE is available in some formats. Record source and percent explicitly.

Common Packaging Formats

Format	Typical weight	Common products
Pouch	5-20g	Refills, snacks, personal care
Bag	2-15g	Mailers and inner bags
Tube	8-25g	Creams and gels

How to Document LDPE

• 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.
