Plastic films or Foils are used in food industry because of their good barrier properties of oxygen, water vapor and other gases. Therefore, barrier properties testing of Food Packaging materials are becoming more important, especially when estimating the shelf life of food.
Labthink Instruments Company is a leader company to supply the testing instruments for food packaging. We offer professional Oxygen transmission rate testers, Gas permeability testing instruments and water vapor permeation testers . All the instruments conform to relative international standards.
OX2/230 Oxygen transmission rate tester and OX2/231 Oxygen transmission rate tester are based on equal pressure method to measure oxygen transmission rate of packaging materials. Differences between these two oxygen transmission rate testers are OX2/231 has three independent testing cells, which can test three different materials in one operation; while OX2/231 Oxygen transmission rate tester also has three testing cells, but they are only to same specimens ang get an average results in operation.
