Packing Peanuts & Void Fill Guide

Packing peanuts fill the empty space in a box after you've wrapped the item. They prevent shifting during transit. Traditional polystyrene peanuts are cheap but environmentally problematic — alternatives are better for eco-focused brands.

Types of Packing Peanuts

Traditional (EPS foam) peanuts

Cheap polystyrene foam, non-biodegradable.

Best for: Cost-sensitive bulk shipping

Biodegradable starch peanuts

Corn or potato starch, dissolves in water.

Best for: Sustainable brands

Air pillows

Inflatable plastic cushions.

Best for: Void fill without particulate mess

Kraft paper fill

Crumpled kraft paper for void fill.

Best for: Curbside-recyclable cushioning

Tissue paper

Fine paper for light cushioning.

Best for: Premium unboxing experiences

Practical Tips

  • Starch peanuts work great but dissolve in humidity — not for wet destinations
  • Air pillows are the most cost-effective at high volume (less material per cubic inch)
  • Kraft paper is fully recyclable and works for most lightweight goods
  • Peanuts create static cling on some products — use anti-static if shipping electronics
  • For eco-conscious brands, paper or starch > polystyrene
