Abstract

Water vapour transmission rate values of co-extruded films having different webs and laminates at conditions of 38+1°C with 90+2% relative humidity and 27 + l°C and 65+2% relative humidity indicated a linear relationship between RH and WVTR for low density polyethylene while hydrophilic polyamide containing composites indicated dependence on RH. The water vapour transmission rate of multi-layer films containing polyamide as the core layer ranged between 4.1 and 5.4 g/m2. day at 38±l°C and 90±2% relative humidity,while monofilms of polyolefίns had values between 1.9 and 3.0 g/m2 .day.
