Ltd., meeting the demands for medical protective clothing testing, integrates medical protective clothing instruments as follows, so as to contribute to the quality testing of medical protective clothing enterprises.
1. Medical Protective Clothing Barrier Property Testing
Barrier property is defined as the barrier effects of packaging materials on gas (e.g., oxygen), liquid (e.g., water vapor) and other infiltrations. Barrier Property is the important factor affecting the product shelf-life. Relevant instruments are listed below:

It is applicable for the gas transmission rate testing of plastic films, laminated films and sheets as well as finished packages. This instrument is fully automatic with three independent chambers and random temperature data curve fitting. It’s with temperature control; LAN data management.
B. PERME OX2/230 Oxygen Transmission Rate Testing System: is of coulometric principle and equal pressure method. This instrument is applicable for the oxygen transmission property testing of films and sheets, as well as bottles, cans and boxes. This instrument is of master base and satellite module mode: one master base can support 9 satellite modules with the realization of 30 samples tested simultaneously.
C. VAC-V Series Differential Pressure Gas Permeability Tester: is applicable for the oxygen, nitrogen and carbon dioxide permeability testing of plastic films and sheets as well as laminated films. This series of instruments, including VAC-V1, VAC-V2 and VAC-V3, etc., complies with differential pressure method.
D. PERME?W3/330 Water Vapor Transmission Rate Testing System: is used for the water vapor transmission rate testing of films and sheets as well as bottles, bags, cans and boxes. This instrument is of Master–satellite mode, one master base can connect 9 satellite modules with the realization of 30 samples tested simultaneously.
E. TSY-T Series Water Vapor Permeability Tester: is applicable in the water vapor transmission testing of packaging materials such as films and laminated films as well as high polymer products. This series of products are fully automatic, computer control and of weighing method. The series includes TSY-T1H, TSY-T1L and TSY-T3, etc.
2. Medical Protective Clothing Strength Testing
Medical protective clothing strength testing includes index testing like material tensile strength testing, peeling strength testing of laminated films, hot seal strength testing, tearing strength and pouch resistance testing. Tensile strength is the maximum strength value just before the material is snapped. Through testing, the package damage and rapture caused by external forces and insufficient packaging material mechanical strength can be resolved effectively. Peeling strength testing, also called complex strength testing, tests the bond strength between the layers of laminated films. If the bond strength is too low, leakage is easily caused by separation among the layers. Hot seal strength testing is to test the strength of the seals. During storage and transportation of products, low hot seal strength will cause problems such as rending and leakage. Pouch resistance is the index evaluating the anti-puncture strength of the package against rigid material.
