CO₂TR: What Carbon Dioxide Transmission Rate Is and How It Is Measured Carbon dioxide transmission rate (CO₂TR) is an important parameter for evaluating the gas barrier properties of films and packaging materials. It describes the amount of carbon dioxide that passes through a material over a defined area and period under specified test conditions. CO₂TR…
DetailsWVTR: What Water Vapor Transmission Rate Is and How It Is Measured The water vapor transmission rate (WVTR) is an important parameter for evaluating the moisture barrier properties of films and packaging materials. It describes how much water vapor passes through a material over a specified area and period under defined test conditions. WVTR testing…
DetailsOxygen Permeability of Films: How It Is Measured and Why It Matters Oxygen permeability is an important property when evaluating films and packaging materials designed to control gas transmission. It describes how readily oxygen can move through a material under defined conditions and helps characterize its barrier performance. Understanding oxygen permeability can support material selection,…
DetailsOTR: What Oxygen Transmission Rate Is and How It Is Measured Oxygen transmission rate (OTR) is an important parameter for evaluating the barrier properties of films and packaging materials. It describes how much oxygen passes through a material over a specified area and period under defined test conditions. OTR measurements help manufacturers, packaging developers and…
DetailsBarrier Films: Properties, Materials and Measurement Methods Barrier films are materials designed to control the transmission of gases and vapor through a packaging structure. They are used in applications where oxygen, moisture or carbon dioxide transmission needs to be limited or characterized. Their performance depends on the materials used, the film structure, the intended application…
DetailsFilm Barrier Properties: What They Are and How to Evaluate Them Film barrier properties describe how effectively a material limits the transmission of gases and vapor through its structure. They are important when selecting and developing packaging materials designed to control the transfer of oxygen, water vapor, carbon dioxide and other substances. Understanding barrier performance…
DetailsHow to Measure the Permeability of a Plastic Film Measuring the permeability of a plastic film helps manufacturers, material developers and laboratories understand how gases and water vapor pass through a material. These measurements are important when comparing film formulations, evaluating barrier properties and selecting materials for packaging applications. The appropriate test depends on the…
DetailsLa permeabilità ai gas è una proprietà che descrive la capacità di un materiale di lasciarsi attraversare da un gas.
Questa caratteristica è particolarmente importante quando un materiale viene utilizzato come barriera per proteggere un prodotto dall’ambiente esterno o, al contrario, per controllare lo scambio di gas tra interno ed esterno della confezione.
