We strive to use packaging materials that maximize product integrity and performance while minimizing environmental waste. All our products are packaged in highly recyclable materials, such as paper-based, unbleached cardboard.

Heat-labile products are shipped in EPS (expanded polystyrene) foam boxes, which is currently the best material for protection, durability and temperature maintenance.

Our foam box return program permits return of the boxes at no cost to you (foam boxes only). However, the fossil fuels consumed by the return of these boxes often exceeds the environmental costs associated with local recycling. Therefore, we encourage you to call Alliance of Foam Packaging Recyclers, 800-944-8448, or visit their website at www.epspackaging.org for information on foam recycling programs close to your location.
