Gas Transmission Rate Testing For Packaging Material

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. Executive Standards QB/T 2358-1998, ASTM F 2029, YBB00122003-2015 Technical Parameters Item Specification Temperature Range Room temperature ～ 250℃ Temperature Control Precision ±1℃ Heat Seal Time 0.1s ～ 99.99h Heat Seal Pressure (0~1) MPa Operation Modes Automatic and manual Air Source Compressed air Dimensions 730(L) mm × 400(B) mm × 535(H) mm Weight 45 kg Power 1200 W Power Supply AC 220V, 50Hz   Product Features Pull-out Loading DesignThe lower pallet features a double-layer stacking structure, enabling pull-out loading that keeps operators away from the upper sealing knife, ensuring both convenience and safety. 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.  

The tear tester (elemendorf method) tests the tear resistance of paper, film, PVC, polyolefin, polyester, composite film, sheet, non-woven fabric, textile, paper, and board, etc. It is controlled by computer automatically and can be tested independently.

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.

Application W301 2.0 water vapor permeability analyzer is designed to test the water vapor transmission rate (WVTR) of films or sheets materials with the principle of Gravimetric Method.

Face Mask Flame Retardant Tester is a special test instrument for the flame retardancy of a mask. Mask testing machines for surgical face masks, N95 masks, Melt-blown fabric.    

A533 water vapor permeability analyzer is to test the water vapor transmission rate (WVTR) of films or sheets materials.

Accelerated weathering tests are performed on materials by simulating ultraviolet radiation and condensation in natural sunlight to obtain results on material weathering resistance. It can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climates. By reproducing these conditions, it can be combined into a cycle and allowed to automatically complete the cycle as required.

  GBL-H2 Electronic Universal Testing Machine High Precision Mechanical Performance Tester Product Introduction GBL-H2 is a universal single-column electronic tensile testing machine developed by GBPI based on GB, ASTM standards and market demands. Equipped with high-precision sensors, it features high accuracy, stable loading and long service life. With LCD display and professional software, it shows real-time test curves and reports. Fully automatic operation with complete safety protections: limit protection, overload protection and emergency stop. Widely used for tensile, peeling, heat sealing, tearing, puncture tests of metal & non-metal materials in food, pharmaceutical, packaging industries, inspection centers and research institutes. Test Principle The prepared sample is fixed between two clamps. Start the instrument to make the clamps move relatively. The force sensor collects force changes, and the displacement sensor collects displacement changes, so as to calculate the tensile, peeling, heat-sealing, tearing and other performance indicators of the sample.
