Void Fill Alternatives: Eco-Friendly Options That Actually Work
The best eco-friendly void fill alternatives are paper-based materials (kraft paper, honeycomb paper) for most applications, with corrugated inserts for heavy items and mushroom packaging for premium protection. Paper-based options offer 85-95% of plastic protection at comparable or lower cost, with full recyclability in standard curbside programs.
Bubble wrap protects products, but your customers hate the waste. Packing peanuts work, but they're a nightmare for recycling. The good news: sustainable void fill options have improved dramatically, and many perform as well as traditional materials—sometimes better.
This guide compares eco-friendly void fill alternatives, their protection performance, costs, and environmental credentials. Not all "green" packaging is equally sustainable, and not all sustainable options provide equal protection.

Biodegradable Packing Peanuts
What they claim vs reality:
| Claim | Reality |
|---|---|
| "100% biodegradable" | Only in industrial composting facilities |
| "Dissolves in water" | Creates a starchy mess |
| "Eco-friendly" | Not accepted in most recycling/composting |
| "Same protection as plastic" | Actually provides less cushioning |
Why we don't recommend them:
| Issue | Impact |
|---|---|
| Composting confusion | Customers don't know how to dispose |
| Facility acceptance | Most composting facilities reject them |
| Static issues | Create more mess than plastic peanuts |
| Settling | Settle 30-40% more than alternatives |
| Cost | 70-100% more expensive than plastic |
| Customer perception | Still look like styrofoam peanuts |
If you must use them:
| Best Practice | Reason |
|---|---|
| Include disposal instructions | Most customers don't know they're different |
| Use only for light items | They crush under weight |
| Overfill by 20% | Account for settling |

Frequently Asked Questions
Is paper void fill really as protective as bubble wrap?
For most products, properly used kraft paper provides 85-95% of the protection of bubble wrap. Honeycomb paper matches bubble wrap protection nearly exactly. The key is proper technique—loosely crumpled paper with plenty of air pockets.
What's the most cost-effective sustainable option?
Kraft paper, especially when using a paper crumpling machine, is typically the most cost-effective. It costs 10-30% less than plastic bubble wrap at scale, with full recyclability.
How do I explain the switch to customers expecting bubble wrap?
Most customers respond positively to sustainability messaging. Include a note: "We've upgraded to recyclable packaging that protects your order while respecting our planet."
Can I use different materials for different products?
Yes, and you should. Use kraft paper for standard items, honeycomb for fragile products, and corrugated inserts for heavy items. This targeted approach optimizes both protection and cost.
How do biodegradable peanuts actually decompose?
Starch-based peanuts require industrial composting conditions that aren't available in home composting or landfills. Most composting facilities don't accept them, making them not significantly better than plastic peanuts.
