IPak's fully automatic flange sealers are engineered to withstand the rigors of heavy-duty industrial applications. IPak flange sealers are capable of folding and sealing single or multiple flanges in either in-line or bi-directional production flow. All FS Series sealers operate with an intermittent production sequence to provide stationary folding and compression of the flanges, including when cases require rear minor flap folding. Productions speeds are controlled by an automatic indexing in-feed gate. Like all IPak machinery, the FS Series flange sealers are known for reliability, dependability and value.

The FS-100 / 200 Series is a series of single line flange sealers available in in-line or bi-directional formats to suit any case style or packaging line.

The FS-300 Series automatically adjusts to three different case sizes and automatically shuttles to accept indexed cases from three separate production lanes.
