Oxygen Transmission Rate (OTR) testing plays a crucial role in ensuring the effectiveness of packaging materials,particularly in industries where product quality and shelf life are directlyimpacted by exposure to oxygen. This testing method measures the rate at which oxygen permeates through packaging materials, providing key insights into thematerial’s ability to act as a barrier against oxygen. Below are the primary reasons why OTR testing is important for packaging: Continue reading
Testing Water Vapor Transmission Rate (WVTR) in films is a critical process for determining how well a material—such as plastic films, packaging materials, or protective coatings—resists the passage of water vapor. This property is essential for industries such as food packaging, pharmaceuticals, textiles, and electronics, where moisture control is vital for product preservation and quality. Continue reading
Now, the war against the new coronavirus has reached the critical stage. 42000 medical staff have come to Hubei from all provinces and cities brought hope to the land of Jingchu. Medical protective clothing is their "battle armor". In hospitals and laboratories with the most dangerous epidemic situation, these "medical practitioners" wear thick protective clothing and fight on the front line of the epidemic. Continue reading
There more and more need to measure the permeability properties of coated paper and paperboard. Labthink, 30-year experiences in packaging testing industries, have a series instruments to measure the oxygen-gases and water vapor transmission rate for high and middle barrier coated paper and paperboard.
