Let it be known that there is no question too basic for us to answer. You’ve asked, we’re here to answer: “What’s that white foam in my package called?” Here at Foam Industries, we know all the information, and we’re here to break it down. Let’s explore what the white foam packaging is called, how it works, whether it’s recyclable, and why people opt for foam instead of paper packaging.
What is the White Foam in Packaging Called?
White packaging foam is typically made from polyethylene, polyurethane or cross-linked polyethylene. If the product is nestled in a large block of white foam in the middle, that’s a custom case insert. These are designed to offer superior protection to products in transit.
Polyethylene (PE) Foam Packaging (Closed-Cell)
Polyethylene foam is the packaging option known for its durability, moisture resistance, and great drop protection. Using CNC-routing and die-cut fabrication methods, this foam can be shaped for numerous products and packaging styles.
Polyurethane (PU) Foam Packaging (Open-Cell)
Polyurethane foam is the softer, more cushion-like packaging option that offers a delicate, lightweight protection for products. An example of this might be the egg-crate toppers you’ve seen. They also work great as layered inserts, used in jewelry boxes, in numerous other applications where something fragile is being shaped.
Cross-Linked Polyethylene (XLPE) Foam (Closed-Cell)
Cross-linked polyethylene foam offers a finer surface for premium cases, medical equipment, aerospace products, and presentation kits. It’s the type of foam you’d use for a beautiful unboxing experience while also providing a highly protective long-term home for the equipment too.
Many people confuse white foam with Styrofoam, which is actually a brand name for expanded polystyrene (EPS). You’ll often find this used for single-use packaging items like food packaging, void fill (think packing peanuts), insulation or block and brace applications. EPS is typically a lot less durable and doesn’t cushion like other types of packaging foam.
Why is Foam Packaging White?
Now that you know what that white packaging foam is, you might be wondering…why is it white?
Most packaging foam is white or black by default, as those are the two most common choices for easier recyclability (more on that later) ,and they can be customized further with more ease than other colors.
Foam also comes in different colors to signify what kind of foam it is. For example, pink foam can often mean anti-static, which can be a good option for electronics. Black foam sometimes signifies that it’s conductive. Other times, it’s just a design preference.
Overall though, packaging foam is more commonly seen in white and black because it’s more neutral and allows for better recyclability. White and lighter colors are much easier for recycling facilities to sort through.
Is White Packaging Foam Recyclable?
The next common follow-up question that consumers have about white foam is: Is white packaging foam recyclable? In general, the answer is usually yes. As for whether you can put it in the recycling bin, the answer to that depends.
In some metro areas, any packaging foam can be placed directly into the recycling bin. To see if this applies to your area, the FPI has an interactive map you can use. For EPS foam, it can also be mailed back to the EPS Industry Alliance via USPS or other carriers. Find your mail back location here.
On a general level, yes, all of the foam in packaging is recyclable. Because it’s made out of thermoplastics, packaging foam can be reused multiple times in different applications by being melted and reshaped.

Which Foam is Best for Packaging?
With so many types of foam available, how do you choose the right one for your product? The answer depends on the item’s weight, fragility, and shipping conditions:
- PE foam is ideal for heavier or more rugged items, providing strong, repeatable protection.
- PU foam is perfect for lightweight, delicate products that need soft cushioning.
- XLPE foam is used when a premium appearance is important, while also offering chemical and impact resistance.
Each foam type is selected based on measurable properties like density, cushioning, and durability, ensuring products are protected during transit while optimizing materials and cost. When in doubt, Foam Industries’ experts can help you determine the best solution for your specific product.
