What is EPS?

Expanded Polystyrene, known as EPS, is a lightweight foam product comprised of 98% air and 2% recyclable plastic. #6 EPS is 100% recyclable. Contrary to popular belief, EPS makes up only about 1% of landfill space, compared to over 25% for paper and cardboard.

How is EPS expanded?

EPS starts out as beads of polystyrene, about the size of sugar granules. Manufacturers use steam to expand the beads to 40-50 times the original size. After expanding, the beads cool to ‘mature.’ The beads are then placed in a mold and reheated with steam so that the beads fill the mold cavity.

How is EPS molded?

Containers, such as those made by Styrotek, use design molds that are filled with polystyrene beads and then heated with steam to fill the mold and connect the beads into a durable, insulating container. We use different processes to vary the density of the packaging. Learn more about custom solutions.

What are the advantages of EPS containers?

Durable EPS containers provide the best possible protection for contents by reducing or eliminating damage. Other benefits include: – Temperature control — allows for cooling, insulates and protects from heat – Moisture shield – prevents bacterial growth and moisture loss in storage and transport – Environmentally friendly – low energy for production, less waste in the supply chain, and 100% recyclable – Safe and efficient – transports easily and reduces injury because no staples, nails, or sharp edges

Is EPS cost effective?

Yes, EPS is cost effective because of its versatility and durability. Produce may stay in the same container from field to cold storage to transport and final destination. The produce is protected from damage, and is shielded from moisture and/or heat. And, because the containers are lightweight, fuel costs for transport are less.

What are the considerations for storing and use of EPS?

EPS containers are easy to store because the materials fit in a simple stack. The light weight and convenient sizes make moving from storehouse to field and back simple. EPS containers have no nails, staples, sharp edges, or splinters making them safer to handle.

Considerations include box size, presence of ventilation holes, thickness and density of foam. Choice of thickness and density relate to how long the boxes will be in storage, and how high the boxes need to be stack.

Can I dispose of EPS by burning?

No. EPS is highly combustible and flammable. Even though EPS emits less carbon monoxide and carbon dioxide than the same volume of burning wood, air pollution regulations forbid burning broken boxes in the field.
