Testing Moisture Vapor Transmission Rate What You Need to Know WVTR Water Vapor Transmission Rate WVTR also referred to as MVTR Moisture Vapor Transmission Rate is a measure of the rate at which water vapor in the surrounding atmosphere will pass through a paper product Water vapor transmission rate measurement for moisture ASTM E9622 Water Vapor Transmission Standard Test Methods Jul 19 2024 What almansyuriah Does Water Vapor Transmission Rate WVTR Mean The water vapor transmission rate WVTR measures the passage of water vapor through a substance of a given unit area and unit time Learn what WVTR is how it affects package performance and how it varies for different films Compare WVTR values for OPP and other common packaging films at 100F and 90 RH Sep 1 2018 The WVTR is normally measured in steadystate by using the electrolytic detection sensor method carrier gas method or by using the gravimetric method referred as steadystate measurement eg according to DIN 531221 Water vapor transmission rate WVTR testing determines how well a material holds moisture also called the barrier effect WVTR is an important parameter in the product development of materials that must withstand different moisture levels at varying temperatures such as food packaging construction materials cosmetics and medical equipment Accurate and stable equalpressure measurements of water MVTR or moisture vapor transmission rate is a key indicator of the effectiveness of barrier materials in preventing damage from moisture Standard Test Method for Water Vapor Transmission Rate What is WVTR Water Vapor Transmission Rate StabilityHub Aug 3 2020 Significance and Use 51 The purpose of this test method is to obtain reliable values for the WVTR of plastic film and sheeting 52 WVTR is an important property of packaging materials and can often be directly related to shelf life and packaged product Smithers packaging material experts work with clients around the globe to provide independent
