What are Fiber Interior Packaging parts made from?

  • 100% Recycled – Made from used corrugate and newsprint
  • Biodegradable – The US Environmental Protection Agency defines Biodegradable as any substance that has the ability to be broken down physically and/or chemically by microorganisms
  • Our parts are produced by creating a slurry made from mixing used corrugated and newsprint with water. The slurry is then pulled through a tool that molds the part, then dried


What type of molded fiber is this?

  • Our products are referred to as thick-wall and range in thickness from 3/16” to 3/8″
  • What is thin-wall molded fiber?: Thin-wall molded fiber typically ranges from about 3/32” to 5/32” and typically both surfaces are smooth. 
  • We use thick-wall molded fiber because it is much sturdier than thin-wall, allowing for better protection against heavy items and helps keep them safe throughout shipping.
  • Parts are produced using a single tool, leaving the front side of the part reasonably smooth and rough on the backside
