WORLD'S FIRST! Introducing the EcoLid® 25% Post-Consumer Recycled Content Food Container Lid, a one-of-a-kind hot cup lid made from 25% post-consumer recycled polystyrene. Traditional food container lids are made entirely with virgin plastic, which is not sustainable. The EcoLid® 25 is an industry-first, recycled content solution that can help keep waste out of landfills.
