Introduction of EVOH High Barrier Film Gas Transmittance Tester Equipment

  This information is published and provided by Jinan Languang Electromechanical Technology Co., Ltd.

  EVOH high barrier film is an important high barrier material, which has very good barrier properties, excellent transparency and gloss, good mechanical strength, good cold resistance and wear resistance, etc., and is widely used in the field of food packaging, especially for foods that need to be stored for a long time, such as meat products, dairy products, juices, etc. Due to its excellent barrier properties, it can effectively extend the shelf life of food and prevent food deterioration and oxidation. At the same time, EVOH film is also used in non-food packaging fields, such as the packaging of chemicals, solvents, cosmetics, health care, pharmaceuticals and electronic products. In these areas, EVOH films also provide excellent barrier properties to protect products from the environment.

【Technical Features】

  • Test principle: Based on the principle of differential pressure method, the gas barrier performance is evaluated by measuring the rate at which the gas passes through the sample.
  • Test range: usually has a high measurement range, such as 0.01~5000 cm³/m² ·· (conventional), to meet the testing needs of different materials.
  • Test conditions
  • Temperature control: Wide range of temperature control (such as 5°C~95°C), temperature control accuracy up to ±0.1°C, to ensure the accuracy of test results.
  • Humidity control: Support testing under a variety of humidity conditions, such as 0%RH, 35%RH~90%RH, etc., to simulate gas permeation under different environmental conditions.
  • Test accuracy: the resolution can reach 0.001 cm³/m² ·· to ensure the accuracy of the test results.
  • Convenience of operation: computer control, the test process is fully automatic, and one-button operation is realized.
