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.

High-Precision Temperature SensorEquipped with a high-precision temperature sensor and PID algorithm for temperature control, achieving a precision of ±1℃, with ultra-high stability and extremely low failure rates. Flexible Testing OptionsFreely switch between manual and automatic testing. 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 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.

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.
