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
