  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. The instrument automatically completes vacuuming, holding, stopping and air-releasing.   Brand-new pneumatic system with fast inflation and return, achieving balanced pressure inside and outside.   Key-controlled cylinder for automatic opening and closing of the sealing barrel lid, labor-saving and convenient.   Supports multiple test methods   Supports bubble method and dye penetration method for leakage / integrity testing.     Application Areas   Plastic Packaging   Leakage testing for plastic bags, plastic containers (bottles, cans, boxes), etc.   Glass Packaging   Leakage testing for food bottles, pharmaceutical glass containers, daily chemical glass bottles, etc.   Metal Packaging   Leakage testing for cans, easy-open cans, aerosol cans, metal hoses, etc.   Other Applications

Film Heat Shrinkage Tester tests various heat shrinkage properties for the film according to the principle of air heating (air bath). Suitable for heat shrinkable films which produced with polyethylene, ethylene copolymers and their mixtures, such as beverage labels, bottled bundle packaging, sausage shrinkage packaging, outer film of daily chemical products, outer film of cigarette boxes, etc. It is a device that can accurately and quantitatively measure the thermal shrinkage force, cold shrinkage force, shrinkage rate, shrinkage time and other properties of plastic films during thermal shrinkage. The test results have a variety of data, which can evaluate the heat shrinkage performance of the film from different aspects, contribute to the research and development of heat shrinkable films of different materials, ensure the stability of heat shrinkable films performance of various materials, and meet the requirements of various heat shrinkable films in various industries. GBPI checks the key thermal shrinkage properties of film products for you. The traditional oven or oil bath equipment only detects the heat shrinkage rate of the heat shrinkable film, and the test results are relatively limited. Our Film Heat Shrinkage Tester GBK-D1 can evaluate the thermal shrinkage performance of films from various data. It is easy to operate, environmentally friendly, with high data accuracy and more comprehensive test results to meet your requirements.

Folding Endurance Tester mainly test the folding endurance on paper, cardboard and other flaky materials, but the thickness less than 1.25mm. Its main technical indexes and performance parameters accord with related national standards.

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 thickness of the film material, an important characteristic of the packaging material, varies and is critical for other properties such as permeability, tensile strength, impact resistance, etc.

  GBB-A3 Heat Sealing Tester Product Introduction GBB-A3 heat sealing tester accurately measures heat sealing temperature, time, pressure and other performance parameters of lid films for jelly cups, yogurt cups, coffee capsules, instant noodle buckets, meal boxes, medical blister packs and other food & pharmaceutical packages. Optimal sealing conditions can be confirmed precisely by testing sealing properties of different materials. Testing Principle Install matched fixture on the lower support plate and place sample steadily. Set sealing temperature, time and pressure as required, then start the device. The upper fixture descends to complete sealing. In manual mode, step on foot switch to press sealing cutter with fixed sealing duration. In automatic mode, upper and lower cutters perform cyclic sealing automatically according to preset parameters. Compliance Standards QB/T 2358-1998, ASTM F 2029, YBB00122003-2015 Technical Parameters Temperature Range Room temperature ~ 250℃ Temperature Accuracy ±1℃ Sealing Time 0.1s ~ 99.99h Sealing Pressure 0~1 MPa Operation Mode Manual & Automatic Air Source Compressed air Overall Dimension 730×400×535 mm Weight 45 kg Power 1200 W Power Supply AC 220V, 50Hz Product Features Pull-out Loading Design Double-layer lower plate enables pull-out feeding, keeping away from sealing cutter for safe and convenient operation.
