Flexible Barrier Materials Heat Seal Strength Testing

Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.

  Product Introduction     The GB-ML Leakage Tester is a professional testing instrument powered by compressed air, which controls the lifting and lowering of the sealing barrel lid through an air cylinder.   Adopting a high-precision electronic pressure sensor and a microcomputer control system, it effectively compares and evaluates the sealing process and sealing performance of flexible packages, and provides a scientific basis for determining relevant technical requirements.   This equipment is suitable for sealing performance testing of flexible packages in food, pharmaceutical, daily chemical and other industries.   Testing Principle   The sample is immersed in water, and a vacuum is applied to the vacuum chamber to create a pressure difference between the inside and outside of the sample.   The sealing performance is judged by observing gas escaping from the sample or water penetrating into the sample.     Applicable Standards   GB/T 15171, ASTM D3078-2002 (2013), USP 1207.2 Item Technical Parameters Vacuum Degree 0～-90 kPa Vacuum Accuracy ±1% of indicated value Vacuum Holding Time 0.01 s～99.99 h Sealing Barrel Size Standard: Φ600×591 mm; other sizes optional or customizable Effective Vacuum Chamber Size Standard: Φ550×396 mm; other sizes customizable Air Inlet Pressure 0.6～0.8 MPa Power 50 W Instrument Dimensions 1005×802×1307 mm Power Supply 220 V, 50 Hz   Product Features   High-quality components, stable and reliable   Built-in high-precision pressure sensor with high sensitivity, enabling real-time monitoring of inlet pressure.   Full-automatic operation system   Vacuum degree and holding time can be set as required.

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.
