Product Brief The N600P Paper & Paperboard Air Permeability Tester is custom-developed to align with standards like GB/T 458-2008 and ISO 5636. It adopts the differential pressure method as its core testing principle, and innovatively integrates three industry-common testing approaches (Gurley, Schopper, and Bendtsen) into a single device.   This tester is applicable to air permeability detection of various paper and paperboard materials, and can measure key indicators including: material air permeability, air resistance, gas transmission rate, and total gas transmission volume. Testing Principle Gurley Method   Under a constant differential pressure of 1.23 kPa, measure the time required for 100 mL of gas to pass through the sample. Schopper Method   Select a suitable test duration under a constant differential pressure (1.00 kPa±0.01 kPa or 2.50±0.01 kPa), and calculate the gas flow rate through the sample by measuring the gas volume. Bendtsen Method   After clamping the sample for 5 seconds under a constant differential pressure of 1.47 kPa, test the gas flow rate through the surface of the sample. Executed Standards GB/T 458-2008, SJ/T 10171-2016, ISO 5636-5:2003, ISO 5636-2:1984, ISO 5636-3:2013, TAPPI T460 Technical Parameters   Item Technical Parameters Test Range 0.1~10 μm/(Pa·s) Resolution 0.001 μm/(Pa·s) Differential Pressure Range 0~5 kPa Pressure Resolution 0.001 kPa Test Area 6.42 cm² or 10.0 cm² Sample Size ＞50 mm×50 mm Instrument Dimensions (L×W×H) 450 mm×400 mm×300 mm Power 100 W Power Supply 110~250 VAC, 50~60 Hz

Application It is to test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow.

  ZF3600 Full-automatic Total Migration Tester is applied to determinate the dissolution amount of packaging materials in different simulant soaking solutions.  

  GBB-C Vertical Heat Sealing Tester Product Introduction GBB-C vertical heat sealing tester accurately measures heat sealing temperature, time, pressure and other performance parameters of plastic stand-up pouches, paper-plastic composite pouches and metal composite pouches. Optimal sealing conditions can be confirmed by testing sealing characteristics of different packaging materials. Testing Principle Place sample on the lower support plate and adjust height properly. Set sealing temperature, time and pressure as required, then start the device. The upper fixture seals samples automatically according to preset parameters. Step on foot switch to complete sealing in manual mode. In automatic mode, cyclic sealing runs repeatedly following set duration.

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.

The tear tester (elemendorf method) tests the tear resistance of paper, film, PVC, polyolefin, polyester, composite film, sheet, non-woven fabric, textile, paper, and board, etc. It is controlled by computer automatically and can be tested independently.

The Leakage tester GB-M2 is designed and manufactured in accordance with the relevant provisions of GB/T15171 Test method for leaks in sealed flexible packages. It is used to detect the sealing condition of plastic packaging bags and containers, and it is applied to used in industries of food, beverage, pharmaceuticals, personal care and so on. Through test can effectively compare and evaluate the sealing technology and sealing performance of packaging parts, and provide scientific basis for determining the relevant technical indicators. It can also be used to test the sealing performance of the specimens after dropping and compressing test.
