Have you ever unpacked a box filled with Styrofoam loose fill? You know the frustration that comes with it. What's the greener solution? None other than dissolvable packing peanuts—made from biogenic materials. How? It vanishes in water in no time. But are they safe? Can you really dissolve them in your sink? Are they edible? So many questions. No problem.
This guide will answer these questions and discuss this alternative to Styrofoam packing peanuts. You will learn how they are made, ways to use them, and how peanuts can be disposed of.

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

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

Soluble foam peanuts are easy to use. Even easier to get rid of. Here’s how to make the most of them.
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.
The rise of dissolvable peanuts is part of a larger movement toward zero-waste packaging. Read here the pros and cons of the sustainable packaging pellets that can help you make the right choice.
