Abstract

A device for reducing presence of microorganisms on a web material for example in a system for manufacture of packages, comprises a housing that defines an interior space, and a microorganism mitigation arrangement in the interior space. Inlet and outlet ports are arranged on the housing to allow the web material to move along a travel path through the interior space between the inlet and outlet ports. The inlet and outlet ports are elongated and comprise a respective seal that defines an elongated slit for flexing engagement with the web material. The device further comprises a spacer which is arranged in the elongated slit of one of the inlet and outlet ports to reduce engagement between the seal and the flat surfaces of the web material at one of its longitudinal edges.
