Oxygen permeability tester

Oxygen permeability tester

PackPerm oxygen can be used for oxygen barrier testing (O2TR) of bags, packaging, small containers, tubes, PET bottles, biodegradable plastic bottles, bottle caps, cork stoppers (natural or synthetic) for glass bottles, and more. PackPerm can measure trace penetration through packaging materials (with better detection limits on the market), as well as visible leaks such as loose connections.

The measurement of O2TR using PackPerm is non-destructive when the packaging is opened; For closed packaging, only two small holes are needed in the sample for testing. The Coulomb type sensor used in the instrument achieved a sensitivity of *. At room temperature, different oxygen concentrations and relative humidity values can be used to measure the inside and outside of the sample. All these parameters are drawn by software. In this way, users can easily evaluate the impact of these factors on the measurement.

Also known as oxygen permeability tester, oxygen permeability meter, oxygen permeability testing system, oxygen permeability tester, etc. This device is suitable for testing the oxygen permeability of packaging containers such as plastic films, high barrier materials, solar panels, sheets, composite materials, aluminum plated films, co extruded films, aluminum foils, sheet materials, as well as bottles, bags, cans, boxes, etc. made of plastic, rubber, paper, glass, metal and other materials.

Detecting Meaning Editing Voice

The barrier performance of packaging mainly refers to the barrier effect of packaging materials on permeable substances such as gases and liquids. Barrier performance testing includes two types: gas (oxygen, nitrogen, carbon dioxide, etc.) and water vapor permeability testing.

Oxygen is an important factor affecting the shelf life quality of products such as food and medicine, and is also an important reference for analyzing shelf life. By testing this project, it is possible to analyze and solve quality problems such as oxidation deterioration, moisture and mold caused by sensitivity to oxygen and water vapor.

Test principle: Edit voice

The principle of electric quantity method, also known as millicoulomb electric quantity method [3], is a popular testing method. The testing chamber is divided into two parts, with the thin film fixed in the middle and high-purity oxygen flowing in the upper chamber of the thin film,

High purity nitrogen gas flows in the lower chamber of the membrane, and oxygen molecules diffuse through the membrane into the nitrogen gas on the other side. The flowing nitrogen gas is carried to the sensor, and the oxygen concentration measured by the sensor is analyzed to calculate the oxygen permeation rate. For packaging containers, nitrogen flows inside the container, while air or high-purity oxygen surrounds the outside of the container.

Introduction to the oxygen permeability test method for packaging materials [4]:

scope

This standard specifies the test method for oxygen permeability of packaging materials in steady state - Coulombometer detection method.

This standard is applicable to the testing of oxygen permeability of packaging materials such as plastic films, sheets, composite materials, plastic composite paper, and plastic coated fabrics. It can determine the oxygen permeability, oxygen permeability, and oxygen permeability constant of packaging materials.
