Product Description

Eastman Cellulose Acetate Propionate (CAP-482-20, Food Contact) is similar to Eastman CAP-482-0.5, Food Contact in solubility and compatibility but Eastman CAP-482-20, Food Contact has a higher viscosity. CAP 482-20, Food Contact is useful as a film former in inks and overprint varnishes. It may be used alone or in combination with Eastman CAP-482-0.5, Food Contact. When CAP-482-20, Food Contact is dissolved in appropriate solvents a clear, colorless solution is produced.

Eastman CAP-482-20, Food Contact is based on cellulose, one of the most abundant natural renewable resources. The calculated approximate bio-content value of 43% for Eastman CAP-482-20, Food Contact was determined by using six bio-based carbon atoms per anhyroglucose unit divided by the total number of carbons per anhyroglucose unit. Although the value reported is not specifically measured for bio-carbon, it can be estimated based on typical partition data.

This product is manufactured, stored, handled and transported by Eastman under conditions adhering to current Good Manufacturing Practices for food contact applications. This product meets requirements for use in certain food contact applications under regulations of the U.S. Food and Drug Administration (21 CFR), European Commission (Regulation 10/2011) and the Switzerland Ordinance of the FDHA on materials and articles intended to come into contact with foodstuffs (817.023.21, Annex 10). Contact your Eastman representative or authorized Eastman distributor for specific regulatory compliance documentation.

For applications that do not require food contact compliance, please refer to Eastman CAP-482-20.
