The food are easily impacted after absorbing moisture, so for food packaging material manufacturer, the packaging materials should be of high moisture barrier property. CPP film is widely used in food packaging which can help extend the shelf life and guarantee the quality of the food.

However, the CPP film may be folded during package forming, product filling, heat sealing and transportation processes and as a result the barrier property (water vapour permeation barrier and oxygen permeation barrier property) may be compromised. Therefore it is necessary to test the CPP film water vapor and oxygen permeability after flex durability tests to guarantee its performance.

GBPI focus on water vapor and oxygen permeability tester since 2001,with more than 17 years experienced R&D team, our WVTR and OTR Analyzer with high precision and accuracy, very popular between home and abroad customers. This article we will simply introduce one of our GBPI hot selling Water Vapor transmission rate and oxygen transmission rate tester for your reference, hopefully it can help you know more about packaging testing equipment.
