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.
EVOH High Barrier Film Gas Transmittance Tester is a professional equipment used to test the gas transmittance rate of EVOH high barrier film and other materials. Here's a closer look at the tester:
【Equipment Overview】
- Applicable materials: EVOH high barrier film, plastic film, composite film, sheet, etc.
- The main purpose: to evaluate the gas barrier properties of the material to ensure that it can effectively prevent the penetration of oxygen, water vapor and other gases, so as to protect the quality of the product and extend the shelf life.
【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.
【Test Application】
- Specimen preparation: The high barrier membrane sample was placed in a dry environment at 5°C for 48 hours to ensure that the specimen was in a stable state.
- Test process: including sample preparation, removal, cutting, clamping, adjusting test conditions, starting the test, data processing and other steps.
- Test parameters: including control parameters (such as test mode, upper cavity purging time, upper cavity pressure, test time, etc.) and sample parameters (such as number, type, area, thickness, etc.).
【Test Results】
- Result output: After the test, the instrument automatically calculates and displays the test results, including key parameters such as gas transmittance, solubility coefficient, and diffusion coefficient.
- Data analysis: Test results can be exported to a computer for further data analysis and processing.
5. Equipment advantages
- High-precision measurement: High-precision sensors and control systems are used to ensure the accuracy and reliability of test results.
- Multi-functional testing: Support a variety of test conditions and parameter settings to meet the testing needs of different materials.
- Easy to operate: computer control, easy to operate, reduce the technical requirements for operators.
- Data security: Support data saving and export functions to ensure the security and traceability of test data.
