Sonderhoff obtains FDA approval

Foam gaskets for food packaging, even if they are in contact with food only for a short time, must comply with the strict criteria of the  FDA  (U.S. Food and Drug Administration) for approval of food and medication in the U.S. Recently, the Sonderhoff USA Corporation from Elgin, Illinois was granted the coveted approval for a 2-component flexible foam gasket of the Sonderhoff product line Fermapor K31, specifically developed for food packaging, by a renowned and independent US certification and testing institute. The certificate was issued in accordance with title 21 of the US Code of Federal Regulation, 21 CFR § 174.5 “General Provisions Applicable to Indirect Food Additives”. According to the approval, the polyurethane foam gasket product Fermapor K31 with the type description “A-LA-384-12-I-2” in connection with the hardener Fermapor K31-B-23 may be used for sealing food packaging. 

The FDA-certified polyurethane foam gasket Fermapor K31 is applied to the food packaging directly on site and hardens at room temperature. An additional advantage compared to the inserted EPDM gaskets is that the polyurethane foam gasket for food packaging provides a seamless seal – in contrast to gasket inserts, the coupling point is not visible and maintains its sealing function even at this position. 

The automated process for sealing food packaging with polyurethane foam gaskets is considered an innovation in the USA which has previously not existed in the market. The FIPFG (formed in-place foam gasket) technology is still new in the American industry and requires time-consuming information campaigns in the production plants.
