Packed with PU-foam-sealed packaging lid, nothing goes out yet

Plastic packaging lids are sealed with SONDERHOFF FERMAPOR K31 sealing foam to protect them from leakage from within and contamination from without.

The application of SONDERHOFF FERMAPOR K31 as a sealant allows packaging to reach the highest UN classification of barrel and container screw lids. Polyurethane-based sealing foam has been used for years by the leading manufacturers of plastic packaging for OPEN TOP containers.

The FDA compliant and EU regulation No. 10/2011-approved polyurethane foam SONDERHOFF FERMAPOR K31 is designed for direct contact with food. It is used as a lid seal for plastic food packaging for aqueous, acidic, alcoholic, fat-containing and dry foodstuffs. It is also suitable for cold, hot-filled or pasteurised milk and for milk products.
