Molded Pulp vs. Expanded Polystyrene (EPS)

EPS or expanded polystyrene packaging has historically been one of the most popular choices for protecting products during distribution. However, with rising oil prices and a growing trend towards the use of environmentally friendly products, EPS packaging is being replaced by molded pulp packaging in hundreds of applications.

Furthermore, while expanded polystyrene is now more readily recyclable in many regions, it still tends to increases package size compared to use of molded pulp. This has the effect of increasing box material and reduces the number of items that can be placed on a pallet, further increasing shipping and storage costs (both financially and environmentally).

See how they compare:

 


Molded Pulp

 


EPS
Material   Made from 100% recycled paper   Produced from a mixture of petroleum based polystyrene and a gasoline blowing agent like pentane or carbon dioxide
Environmental Aspects   Sustainable product that is fully recyclable, bioedegradeable, and compliant with ISO 14000 and European Green Dot standards.   Non-biodegradeable material facing bans in many countries and communities.
Price   Stable cost bases that often leads to lower overall cost.   Prices are ties closely to rising oil and resin prices.
Protection   Excellent vibration dampening and cushioning properties.   Good vibration dampening and cushioning properties.
Storage & Shipping   Product nests during shipment and storage allowing for tremendous cost and environmental savings.   Product rarely nests requiring bulky shipments and extensive storage space requirements.
Temperature Resistance   Unaffected by extreme temperature.   Temperature affects flexibility and can break at low temperatures and lose cushioning properties at high temperatures.
Static   Static neutral material ideal for electronic components.   Typically requires treatment with anti-static agents to comply with electronic industry specs.
