Packing Peanuts: The Unsung Heroes of Safe Shipping

When you think about shipping delicate or fragile items, what comes to mind? Bubble wrap, cardboard boxes, or maybe even foam sheets? While these are all valuable packaging materials, there’s another unsung hero that plays a crucial role in protecting your items during transit – packing peanuts. These lightweight and versatile little wonders are more than just fillers; they provide essential cushioning and help ensure your packages arrive intact and damage-free.

In this article, we’ll dive into the world of packing peanuts, exploring their uses, benefits, and environmental impact.

  1. What are Packing Peanuts?
    Packing peanuts, also known as foam peanuts or loose fill, are small, lightweight, and bead-like materials made from expanded polystyrene (EPS) or biodegradable materials like cornstarch. They are designed to be used as a void fill material, creating a protective layer around fragile items within a shipping box. Their ability to conform to the shape of the items helps prevent shifting during transit, reducing the risk of damage caused by impacts and vibrations.
  2. The Benefits of Using Packing Peanuts
    Shock Absorption: One of the primary purposes of packing peanuts is to absorb shocks and impacts during transportation. When placed around delicate items, the peanuts create a protective cushion that helps to dissipate the force of any sudden jolts or drops, keeping the items safe from harm.

Lightweight and Cost-Effective: Packing peanuts are extremely lightweight, which means they don’t add much to the overall shipping weight. This characteristic can lead to cost savings, especially when shipping items over long distances.

Versatility: Packing peanuts can be used to protect a wide range of products, from fragile glassware and electronics to delicate artworks and antiques. They come in different sizes and densities, offering flexibility to cater to various packaging needs.

Ease of Use: Using packing peanuts is straightforward. They can be poured directly into the box, filling in gaps and providing instant protection to the items within. Moreover, they are easily moldable to fit any shape, ensuring optimal coverage.

Resistant to Moisture and Dust: Packing peanuts do not absorb moisture, and they resist dust accumulation. This helps maintain the integrity of the packaging and ensures the items remain in pristine condition.

  1. Eco-Friendly Alternatives
    Traditional packing peanuts made from expanded polystyrene are not biodegradable and can contribute to environmental pollution. However, eco-conscious consumers and businesses now have alternatives to consider. Biodegradable packing peanuts, made from renewable resources like cornstarch or wheat, offer the same protective benefits as their non-biodegradable counterparts but break down more easily in landfills and composting facilities, reducing their environmental impact.
  2. Proper Disposal and Recycling

If you receive a package filled with packing peanuts, it’s essential to dispose of them responsibly. Many shipping companies and packing supply stores offer recycling programs where you can return used packing peanuts for reuse. Additionally, biodegradable packing peanuts can be safely composted, contributing to a more sustainable waste management system.

Let’s discuss packing peanuts, edible or not?
The answer is NO!! Traditional packing peanuts made from expanded polystyrene (EPS) are not edible and should never be consumed. EPS packing peanuts are made from a type of plastic that is not meant for human consumption and can be harmful if ingested. These packing peanuts are not biodegradable and are designed solely for the purpose of providing cushioning and protection during shipping.

On the other hand, there are biodegradable packing peanuts made from materials like cornstarch or wheat, which are generally considered safe for the environment. While these biodegradable packing peanuts are not intended for human consumption either, they are made from food-grade materials and are less harmful if accidentally ingested. However, it is still not recommended to eat them.

Biodegradable packing peanuts are a more environmentally friendly alternative to traditional packing peanuts made from non-biodegradable materials like expanded polystyrene (EPS). These peanuts are designed to provide the same protective cushioning for fragile items during shipping while also being less harmful to the environment. Here’s what you need to know about biodegradable packing peanuts:

  1. Material Composition:
    Biodegradable packing peanuts are typically made from natural and renewable materials, such as cornstarch (starch-based) or wheat. These materials are chosen for their ability to break down more easily in the environment compared to EPS.
  2. Biodegradability:
    Unlike traditional EPS packing peanuts that take hundreds of years to decompose, biodegradable packing peanuts are designed to break down relatively quickly when exposed to moisture and other environmental conditions. This means they can be composted or disposed of in a way that is less harmful to the environment.
  3. Non-Toxic and Food-Safe:
    Biodegradable packing peanuts are considered non-toxic and safe for handling. They are also food-safe, meaning they are made from materials that are commonly used in the food industry. However, it’s important to note that they are not meant for human consumption and should not be eaten.
  4. Disposal and Recycling:
    When it comes to disposing of biodegradable packing peanuts, there are several options available. The most eco-friendly approach is to compost them, as they will break down naturally and enrich the soil. Many municipal composting facilities can process these peanuts. If composting is not an option, some packing peanuts can be dissolved in water, and the resulting solution can be safely poured down the drain. Additionally, some shipping companies and packing supply stores may accept used biodegradable packing peanuts for recycling or reuse.
  5. Similar Protective Properties:
    Biodegradable packing peanuts offer similar protective properties to traditional EPS peanuts. They are lightweight and can effectively cushion fragile items, keeping them safe during transit.
  6. Consideration for Humidity:
    One potential drawback of biodegradable packing peanuts is their sensitivity to moisture. They may start to break down or dissolve when exposed to high humidity or water. For this reason, it’s essential to store them in a dry environment and avoid using them in packages containing items that are likely to release moisture.


Biodegradable packing peanuts are a more environmentally conscious choice for protecting fragile items during shipping. They are made from renewable resources, break down more readily in the environment, and offer comparable protective properties to traditional packing peanuts. While they are considered safe for handling, they should not be ingested, and proper disposal or recycling methods should be followed to minimize their impact on the environment.

Final word:
In conclusion, packing peanuts may be small, but their impact on ensuring the safe delivery of fragile items is substantial. By providing shock absorption, cost-effectiveness, and versatility, they have become a staple in the shipping industry. As environmental concerns grow, the availability of biodegradable options ensures that these little protectors can continue to serve their purpose without leaving a lasting mark on our planet.

Next time you unbox a fragile purchase and find it perfectly intact, take a moment to appreciate the packing peanuts that made it possible!
