Heat Shrink Tester ASTM D2732 GBK-1

Product Introduction The GBB-A3 Lid Film Heat Sealer can accurately determine heat seal performance parameters (including heat seal temperature, time, and pressure) for lid films used in food and pharmaceutical packaging, such as those for jelly cups, yogurt cups, coffee capsules, instant noodle buckets, meal boxes, and medical blister packs. Since heat seal performance varies across different materials, measuring these parameters allows for precise determination of optimal heat seal conditions. Testing Principle Install appropriate fixtures on the instrument’s lower pallet and place the sample on the fixture. Set the desired heat seal temperature, time, and pressure, then start the instrument with one click—the upper fixture will descend to seal the sample. In manual mode, pressing the foot switch once activates the sealing knife, and the heat seal duration is determined by the preset time. In automatic mode, the upper and lower sealing knives repeatedly perform heat sealing automatically according to the set time.

The automatic mode saves time with fully automated, repeatable heat sealing; the manual mode includes a compatible foot switch—pressing it once activates the sealing knife, ensuring safe and easy operation. Advanced Pneumatic Drive SystemComposed of a pressure gauge, pressure regulating valve, and cylinder, the system uses compressed air. Pressure is adjusted via the valve to precisely lock air pressure, enabling pneumatic-driven heat seal clamping for efficient operation. Extensive Customization Services Custom fixed fixtures can be made according to samples, and fixtures are interchangeable based on cup sizes. The sealing knife can be upgraded with anti-stick functionality for a better user experience, making it easier to determine optimal heat seal conditions. Customizations for the shape, size, and smoothness of the sealing surface are available to meet diverse research needs.

Product introduction The GTR-10H gas permeation analysis system consists of a differential pressure permeation device and a gas chromatograph. It can test and analyze the gas permeability of various single-component gases and mixed gases, and can accurately calculate the permeability, permeability coefficient and other parameters of each component gas. The test gas has a wide range of types and high accuracy, and is suitable for gas permeation testing in the fields of fuel cell proton exchange membrane gas permeability testing, hydrogen permeation of hydrogen storage materials, gas density of bipolar plate materials, and natural gas storage materials.   Test principle Place the processed sample between the high-pressure chamber and the low-pressure chamber, and the low-pressure chamber is connected to the gas chromatograph through a quantitative loop. At the set test temperature, use a vacuum pump to evacuate the gas system, and then add a certain pressure of test gas to the upper chamber to form a constant pressure difference between the upper and lower chambers. Under the action of the pressure gradient, the gas penetrates from the high-pressure chamber to the low-pressure chamber through the film. The system injects the gas that penetrates into the low-pressure chamber into the gas chromatography column and separates it into various components, and calculates the gas permeability, gas permeability coefficient and other barrier performance parameters of each component.   Standard GB/T 20042.3，GB/T 20042.6-2011，GB/T 1038.1-2022，ISO 15105-1   Specification Item Technical Parameters Test range 2.0×10-12~3.0×10-7 mol/(m2·s.Pa) Detection system Gas chromatography (GC), TCD detector Test gas Gases such as hydrogen, oxygen, nitrogen, carbon dioxide, carbon monoxide, methane, etc., single component or mixed component Gas pressure 0~300kPa Permeation module temperature control range 15~60℃ Temperature control accuracy ±0.1℃ Permeation area 50.24 cm2 Sample size Φ110 mm Sample thickness ≤2 mm Sample quantity 1 piece Power supply AC 220 V，50 Hz   Features Advanced gas chromatography analysis technology The instrument is equipped with an advanced gas chromatography analysis module and a new microcomputer temperature control system, which can achieve 16-step program temperature rise with high temperature control accuracy; it adopts multi-processor parallel working mode, and can be equipped with a variety of high-performance detectors.

Product Profile • The W416 2.0 Infrared Method Water Vapor Transmission Rate Tester is a high-end precision testing instrument for packaging materials, newly developed and upgraded by Guangzhou Standard International R&D Team in full compliance with the requirements of **GB/T 26253** and **ASTM F1249** standards as well as market demands. • Based on the testing principle of infrared moisture analysis sensors, it provides wide-range, high-efficiency water vapor transmission rate (WVTR) testing for high, medium and low barrier materials. • It is suitable for testing the water vapor transmission performance of films, sheets, papers, packages and other related materials in industries such as food, pharmaceuticals, medical devices, daily chemicals, photovoltaic electronics, etc. • It is an ideal offline or online configuration instrument for manufacturers in the packaging industry to test the barrier performance of packaging materials. Testing Principle The W416 2.0 Water Vapor Transmission Rate Tester adopts the infrared method principle: 1. Fix the pre-treated sample in the middle of the test chamber, dividing the chamber into a high-humidity chamber and a low-humidity chamber. 2. Compressed air flows through the high-humidity chamber, while dry nitrogen (carrier gas) flows through the low-humidity chamber at a constant flow rate. 3. Due to the humidity gradient, water vapor penetrates from the high-humidity chamber to the low-humidity chamber. 4. The water vapor passing through the sample is carried to the infrared sensor by the flowing dry nitrogen. 5. Parameters such as the sample’s water vapor transmission rate are derived from the electrical signal output by the sensor.
