  The coefficient of friction tester GM-4 is a measuring instrument developed and manufactured by the Guangzhou Biaoji R&D team based on various test standards of GB, ISO, ASTM and market demand. The measured friction coefficient determines the smoothness and opening difficulty of the film. and uniformity can be accurately determined, so as to correctly guide the production. It is suitable for measuring the static friction coefficient, dynamic friction coefficient and peel strength of plastic films, composite films, aluminum foils, aluminized films, plates, rubber, ceramics and other materials when sliding.        

Introduction Based on the test principle of the differential pressure method, N530 is designed with reference to the GB/T 1038 standard and used to test the gas transmission rate (quantity) of film or sheet materials.

GX-B3 type disc peeling tester is used for testing the adhesion fastness of printing ink layer of plastic film and cellophane decorative printed materials (including composite film printed materials) produced by gravure printing process. It can also be used to test the adhesion state of the surface layer formed by vacuum coating, surface coating, compounding and other related processes.  

Introduction The N530A 2.0 Gas Permeability Tester is designed and manufactured based on the differential pressure testing principle, in accordance with standards such as GB/T 1038 and ISO 2556. It adopts a high-precision pressure sensor and automatic pressure difference maintenance technology, ensuring high testing accuracy. It is suitable for testing the gas permeability of films, sheets, paper, packaging materials and related products in fields including food, pharmaceuticals, medical devices, daily chemicals, and photovoltaic electronics. It provides wide-range and high-efficiency gas permeability detection for high, medium, and low gas barrier materials.

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

It meets the requirements of GB 5009.156‑2016 and applies to all non‑volatile food simulants specified in GB/T 23296.1‑2009, GB 31604.1‑2015 and other relevant standards. It provides standardized test conditions to support safety assessment for food‑contact specimens, widely adopted by third‑party laboratories, food packaging manufacturers and research institutes. Executive Standards To ensure test repeatability and global recognition, MC‑D Migration Test Cell conforms to both Chinese national standards and European normative requirements: GB/T 23296.1‑2009, EN13130‑1:2004, GB 5009.156‑2016, GB 31604.1‑2015, EN1186‑1:2002. It satisfies migration pre‑treatment requirements for domestic inspection and EU export certification. Core Technical Parameters Contact Mode Single‑sided contact Contact Area 99.17 cm² Contact Surface Diameter Φ112.4 mm Volume 300 mL Operating Temperature 5℃ ~ 120℃ Product Features • Designed and manufactured with reference to Type‑D cell in Appendix C of EN1186‑1:2002, Type‑D cell in Appendix D of GB/T 23296.1‑2009 and Type‑D cell in Appendix D of EN13130‑1:2004, ensuring consistency of migration test results. • This migration cell supports both migration‑cell method and total‑immersion method to meet diverse pre‑treatment requirements. • Constructed of premium borosilicate glass featuring high hardness, high light transmittance and excellent chemical stability. It is heat‑resistant with low matrix content and will not interfere with the determination of overall migration and specific migration values. • Adjustable stainless‑steel latches enable simple operation and reliable sealing. It prevents burst under high‑temperature conditions with various food simulants, guaranteeing test safety and stable migration results. • For non‑reflux immersion, the opening can be sealed and fixed directly with glass plug to carry out total‑immersion tests at ambient and high temperatures. • For reflux immersion, a condensation reflux tube can be directly connected to the ground‑glass joint for migration testing. Application Fields It applies to migration test pre‑treatment of food‑contact materials and products exposed to food simulants including water, acetic acid and ethanol. Conclusion MC‑D Migration Test Cell is a standard‑compliant auxiliary device for food‑contact material safety testing. Made of high‑performance borosilicate glass, it supports both migration‑cell and total‑immersion approaches, compatible with non‑reflux and reflux immersion workflows. With safe anti‑burst performance under high‑temperature testing, it delivers repeatable migration pre‑treatment results for lab QC, third‑party testing institutes and packaging manufacturers.
