ABSTRACT:
An apparatus for treating polymeric sheet material to improve surface adhesion thereof. The apparatus comprises a preheating station, a treatment station, a rinsing station, a drying station and a reeling station. In the treatment station spray nozzles are used to contact a surface of the material with an oxidizer (NaOCl) and an activator (succinic acid) at an elevated temperature to shorten the treatment time. A spent treatment disposal system is disclosed along with a scrubber for cleaning the atmosphere of the treatment and rinsing stations. Alternatively, treatment is accomplished in a heated, agitated bath.
