Filter papers for the clarification of oils

Recommended for the clarification of edible and technical oils and fats.

  • The pure raw materials – Cotton Linters and Cellulose are used in the production of these filter papers, which allow their use with food and beverages.
  • For selected types, the conformity to both the U.S. FDA recommendation 21 CFR and by the German BfR (Federal Institute for Risk Evaluation) recommendation XXXVI and XXXVI/1 (1.6.2009) can be approved.
  • Broad range of papers with optional filtration time and retention rate, meeting the needs of individual viscosities.
  • Particularly voluminous papers are the best medium to filter highly viscous liquids. Creped papers shorten the filtration time as the surface is enlarged.
  • Qualified for the use in filter presses.
