Moisture Barrier Testing for BOPP Film

Moisture Barrier Testing of BOPP Film High moisture barrier performance is a must for flexible package so as to avoid deterioration caused by moisture. At present, this factor is not fully noticed by the flexible packaging manufacturers. Labthink PERME W3/030 is developed according to ASTM E96, ISO 2528 and other standards to test moisture transmission rate for materials. The lower WVTR the better. But, higher barrier property means more costs. Therefore, the common data is less than 10g/m2.day or 5g/m2.day. BOPP [...]
