GBD-L Falling Dart Impact Tester test the impact resistance of various films, metallic foil and so on, widely used in industries of packaging, plastic films, laboratory, research institute, inspection agency and so on.

GBD-L2 falling dart impact tester is suitable for testing materials such as plastic film or sheet and steel plate coating with a thickness of less than 1mm. Under a given height of free falling dart impact, it can measure the energy (in Quality to express results) of plastic films,thin section specimens and other materials. Through the impact resistance test, it can prevent the packaging surface from being damaged when the packaging material is impacted or dropped due to insufficient toughness of the packaging material, and effectively avoid the product from being damaged due to impact or falling in the circulation link. It can be used in scientific research, teaching, industrial and mining enterprises, laboratories, research institutes and quality supervision departments.

The identification and quantitation of residual printing solvents in synthetic packaging materials are very important for the material packaging suppliers, the printers and the packaging users of food and pharmaceutical products.

Introduction It is used to determine the MFR & MVR value of the melt flow rate through the standard die every 10 minutes when various plastics and gums pass through a certain temperature and load in a viscous flow state. It is suitable for melting high temperature polycarbonate, polysulfoxide, fluorine plastics, nylon and other engineering plastics. Also, it is appropriate for the polyformaldehyde, polystrene, polypropylene, ABS resin polyformaldehyde, polycarbonate resin and other low temperature plastic melting test. The machine is widely used in plastic production, plastic products, petrochemical and other industries as well as related universities, scientific research units and commodity inspection departments. 

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.

     

To test the tensile strength, peeling strength, heat sealing strength and tearing strength of plastic film, composite film, tape, soft packaging material, rubber sheets, paper, non-woven fabrics and other packaging materials, widely used in industries of membrane, packaging, pharmaceuticals, food, inspection agency, research institute, college and so on.

           

Face Mask Flame Retardant Tester is a special test instrument for the flame retardancy of a mask. Mask testing machines for surgical face masks, N95 masks, Melt-blown fabric.    

N500 Gas Permeability Analyzer to test the gas (O2, N2, CO2 etc) transmission rate (GTR) of packaging materials, films and sheets materials

It is suitable for the resistance of the mask to the penetration of synthetic blood under different levels of test pressure. The mask material is tested with synthetic blood under continuously applied pressure, and the penetration of synthetic blood on the material is visually checked.

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
