Gas Transmission Rate Testing For Packaging Material

Oxygen transmission rate (OTR) is the measurement of the amount of oxygen gas that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description.

Used for face mask air flow resistance and differential pressure testing to check breathability and can also be used to check differential pressure of textile materials gas exchanger.

GBPI offers mask testing machines for surgical face masks, N95 masks, Melt-blown fabric. BFE Tester, PFE Tester, N95 Tester, Melt-blown fabric Tester

The respiratory resistance tester is suitable for determining the inhalation resistance and exhalation resistance under the regulations of respirators and masks, and for the related testing and inspection of ordinary mask products by the national labor protection equipment inspection agency manufacturer.

Introduction Based on the test principle of the differential pressure method, N530 is designed with reference to the GB/T 1038 standard and used to test the gas transmission rate (quantity) of film or sheet materials.

  The coefficient of friction tester GM-4 is a measuring instrument developed and manufactured by the Guangzhou Biaoji R&D team based on various test standards of GB, ISO, ASTM and market demand. The measured friction coefficient determines the smoothness and opening difficulty of the film. and uniformity can be accurately determined, so as to correctly guide the production. It is suitable for measuring the static friction coefficient, dynamic friction coefficient and peel strength of plastic films, composite films, aluminum foils, aluminized films, plates, rubber, ceramics and other materials when sliding.        

W416 2.0 Infrared Water Vapor Transmission Rate Tester High Precision WVTR Tester | 6 Independent Test Chambers Product Introduction W416 2.0 Infrared Water Vapor Transmission Rate Tester is an upgraded high-end precision testing instrument developed by GBPI R&D team in accordance with GB/T 26253, ASTM F1249 and international standards. Based on infrared moisture sensor technology, it provides wide-range and high-efficiency WVTR test for high, medium and low barrier materials. It is widely used for films, sheets, paper, packages and materials in food, pharmaceutical, medical devices, daily chemical, photovoltaic and electronics industries, ideal for offline and online testing in packaging industry. Get a Free Quote Today   Test Principle W416 2.0 adopts the infrared sensor testing principle. The pre-processed sample is fixed in the test chamber, dividing it into wet and dry sides. Compressed air flows in the wet chamber, and dry nitrogen (carrier gas) flows in the dry chamber at a fixed rate. Due to humidity gradient, water vapor permeates to the dry chamber and is carried to the infrared sensor. The WVTR value is calculated by the electrical signal output from the sensor.   Compliant Standards ISO 15106-2 ISO 21760-1 ASTM F1249 GB/T 26253 JIS K7129-2 Chinese Pharmacopoeia 4010 YBB 00092003   Technical Specifications Item Value Test Range 0.002~100 g/(m²·24h) Repeatability 0.005 or 2% (whichever is greater) Resolution 0.0001 g/(m²·24h) Temperature Range 15~45℃ Temperature Accuracy ±0.1℃ Humidity Range 5~90%RH, 100%RH Humidity Accuracy ±1%RH Test Area 50.24 cm² Sample Size Φ100 mm Sample Thickness ≤3 mm Test Chambers 6 channels (independent data)   Key Features Patented high-precision infrared moisture sensor, ultra-high stability, resolution up to 0.0001 g/(m²·24h).
