Amazon is shifting from the plastic air pillows used for packaging in North America to recycled paper because it’s more environmentally sound, and it says paper just works better.

The company said Thursday that it’s already replaced 95% of the plastic air pillows with paper filler in North America and is working toward complete removal by year’s end.

“We want to ensure that customers receive their items undamaged, while using as little packaging as possible to avoid waste, and prioritizing recyclable materials,” Amazon said.
