The distribution of filamentous fungi was studied in a production line for plastic caps for soft drinks. Of 52 samples from both the swab and air sampling tests, a total of 47 filamentous fungi were isolated. Of those 47 fungi, 32 (68.0%) were found in the swab test samples. As for the swab test results, the area where most of the filamentous fungi were isolated was the printing/inspection room followed by the resin storage room. The breakdown of the filamentous fungi showed <I>Cladosporium</I>: 14.9%; <I>Penicillium</I>: 10.6%; <I>Acremonium</I>: 8.5%; <I>Trichoderma</I>: 8.5%; <I>Arthrinium</I>: 6.4%; and <I>Aureobasidium</I>: 6.4%. The fungal count of raw material (MPN/100g) was zero for the base resin, 0.36 for the master batch and 4.3 for the liner material, respectively. Those fungal counts seemed to be very low and it was concluded that the hygienic conditions of the plastic cap production line were very good.
