Packing foam is a low density product made from the same material as polystyrene. The main difference between the two is that packing foam has air mixed in with it, which makes it very light but also makes it less durable.

What is Packing Foam

Packing foam, also called packing peanuts or polystyrene beads, is an inexpensive and effective way to protect your fragile items during shipping. Most people know that it’s made of plastic beads, but did you know that these beads are usually made from oil? Yep! The same oil used to make plastic cups, water bottles and disposable plates is also used to make packing materials.

The process of making packing foam involves blending the plastic with other additives until it reaches a consistency similar to sand. It’s then extruded through a small hole onto a conveyor belt where it dries into little balls. These balls are then put into bags for sale as packaging peanuts or loose in boxes when sold at retail stores as bubble wrap (which we’ll talk about later).

Packing foam is hypoallergenic so anyone who has allergies can use it without fear of irritation from allergens like mites or dust mites which cause many allergic reactions such as hives or asthma attacks depending on the severity of symptoms associated with allergies such as these two examples mentioned above.”

What is Polystyrene?

Polystyrene is a type of plastic that can be recycled. Polystyrene is used in a wide range of products, including construction materials and packaging.

In the construction industry, polystyrene foam (PSF) is often used as insulation to help with energy efficiency and noise reduction.

In the packaging industry, PSF is typically found as packing material for fragile products that need extra protection during shipping or storage. The material works well at keeping things safe from damage because its open cell structure allows air to flow through it easily but also traps any small particles inside for added protection against breakage.

The difference between polystyrene and packing foam

In short, polystyrene is a high density product and packing foam is a low density one. This means that polystyrene has more material in it than packing foam, which leads to better insulation. Just like the difference between an SUV and an economy car can be measured in miles per gallon or horsepower, so too can the difference in these two types of insulation be measured by their respective densities. The density of any material is simply how much stuff there is as compared to its volume (or how much space it takes up). Density is usually expressed in kilograms per cubic metre (kg/m3), which sounds intimidating but really just means how many kilograms fit into each cubic metre of volume.

Both polystyrene and packing foam are products made from the same material, with the only difference being that polystyrene has a high density while packing foam has a low density.

Polystyrene and packing foam are both made from the same material. The only difference between them is that polystyrene has a higher density than packing foam. Polystyrene is used in applications such as building insulation and packaging materials because it can hold its structure well, especially under high temperatures or pressure. Packing foam has a lower density than polystyrene due to its loose structure; this makes it ideal for protecting fragile items during shipping because it will crush into smaller pieces if an accident occurs during transit.


As you can see, there are many differences between the two products that can help determine which one is right for your project. It’s important to consider these factors when deciding whether or not to use packing foam or polystyrene so that you get the best possible end result.
