Bean Bag Fillers

Whether you’re looking to re-inflate your old bean bag chair or just want to add some extra comfort to a pillow or blanket, it’s important to choose the right filling. While the type of filler you use depends on your personal preference and the purpose of the object, there are many options available to suit your needs, from traditional Styrofoam beads to memory foam scraps.

The majority of bean bags use expanded polystyrene bead, known as EPS, for their comfortable, durable, and lightweight properties. EPS bead are manufactured in specialized machines that heat up the raw product to cause a blowing agent (like pentane or carbon dioxide) to vaporize and expand the beads, creating a cellular structure that is lightweight and highly compressible. During this process, manufacturers monitor the consistency of the beads to ensure consistent comfort and support for their customers.

Once the EPS bead have undergone rigorous quality control measures, they are ready for packaging and distribution. They are usually packaged in large plastic sacks that are sealed to prevent air leakage and maintain the bead’s freshness during storage and shipping. During this stage, the bags are also tested for flammability to ensure that they do not pose a fire risk.

Another popular option for bean bag filling is EPP, or expanded polypropylene. EPP bead are manufactured by heating up the raw product in a specialized machine to allow the blowing agent to vaporize and expand the beads, which are then cut into smaller uniform sizes. Like EPS bead, EPP bead are a cost-effective and durable choice for bean bag filler, but they are less flexible than EPS and are sensitive to heat and oxygen. Because of these drawbacks, EPP is not as widely used in bean bag filling as EPS bead.
