What Makes Packing Peanuts Dissolvable?

Dissolving packing peanuts are made from natural starches - all renewable, plant-based sources. The most common materials are cornstarch and potato or wheat starch, which:

  • Are biodegradable and compostable
  • Contain no toxic chemicals or plastics
  • Dissolve completely in water
  • Leave zero microplastic residue

Why Businesses Are Switching to Dissolvable Peanuts

More and more eco-conscious brands and online retailers are turning to dissolvable packing peanuts as part of their sustainable packaging strategies. These peanuts not only help reduce a company’s carbon footprint but also enhance the overall customer experience. 

By using biodegradable loose fill, businesses show their commitment to the environment, which significantly improves brand perception among green-minded consumers. The easy disposal process adds another layer of convenience for customers, making unboxing smoother and more enjoyable. 

Additionally, adopting eco-friendly materials helps companies comply with modern sustainability regulations and policies. In short, switching to dissolvable packing peanuts isn’t just a step toward a greener planet—it’s also a smart move for brand reputation and long-term business growth.

How Do Water-Soluble Packing Peanuts Work

These innovative peanuts act as loose-fill packaging materials that provide void-fill protection, cushioning, and shock absorption — much like their polystyrene counterparts. 

Take a look at their key properties that help them perform better:

  • Lightweight yet shock-absorbent
  • Anti-static
  • Dissolve instantly in water. No disposal needed
  • Positive eco Impact

A single batch of cornstarch packing peanuts decomposes in just 2–4 weeks in a compost bin.

Ways to Use & Dispose of Dissolvable Packing Peanuts

Soluble foam peanuts are easy to use. Even easier to get rid of. Here’s how to make the most of them.

To use:

1. Prepare your box: 

Line the bottom of your shipping box with a layer of dissolvable peanuts to create a soft, shock-absorbing base.

2. Cushion your items: 

Place your product or fragile item in the center, then pour additional peanuts around it until all gaps are filled. Make sure your items can’t shift during transit.

3. Seal and ship:

Gently press down the top layer of peanuts to compact them slightly before sealing the box. They’re lightweight, so they won’t add unnecessary shipping weight.

Bonus: Ideal for mailing glassware, electronics, crafts, or any delicate goods that need secure yet sustainable protection, peanuts must be stored in a dry place or a sealed bag.

To dispose:

  • Run under tap water → dissolves in seconds
  • Pour starch water down the drain.
  • Check your local facilities. Some industrial composting programs may accept them. 
  • Or compost—breaks down like food scraps
