Metal covers seal perfectly with PU foam or PVC foam

Lids for metal packaging made of black plate, tinplate or steel are made tight with FERMAPOR K31 sealing foam to prevent leakage of the container contents or contamination from the outside.

By using FERMAPOR K31 as a sealant, the highest UN classifications of lids for steel drums and metal hobbocks/pails can be achieved. Polyurethane-based sealing foams have been used for years by the leading manufacturers of metal packaging containers.

As an alternative, we also offer our single component PVC plastisol FERMAPOR DD980 for sealing tin lids.

The phthalate-free FERMAPOR DD980 PVC Plastisol is approved for food packaging by EU regulation No. 10/2011 Therewith they also fulfil the requirements of the German LFGB (according to §§ 30 and 31 part 1 of the food and fodder laws), judging by the guidelines laid down by the EFSA (European Food Safety Authority). They are used as lid sealants for metal canisters in direct contact with liquid aqueous, acidic, fat-containing and dry foodstuffs.
