|---|---|
| Transmission rate test of hazardous gases such as hydrogen and methane, etc. | Based on the principle of differential pressure method, gas transmission rate can be determined for various plastic films, co-extrusion films, aluminum-coated films, aluminum foil composite films, etc. |
| Transmission rate test of organic gases such as benzene, ester, alcohol and ketone, etc. | The combination of equal pressure method and chromatographic analysis technique is used to quantitatively determine the barrier properties of organic gases (such as benzene, ester, alcohol, ketone, aldehyde, ether, etc.) of plastic films, composite films, sheets, etc. |
| Gas transmission rate test in various humidity environments | Based on the principle of differential pressure method, gas transmission rate in various humidity environments (5~90% RH) can be determined for various materials such as plastic films, co-extrusion films, aluminum-coated films, aluminum foil composite films. |
| Gas transmission rate test in various high pressure environments | Based on the principle of differential pressure method, gas transmission rate in various high pressure environments (0.1~4 Mpa) can be determined for various materials such as rubber, plastic films, co-extrusion films, aluminum plating films, aluminum foil composite films. |
| Gas transmission rate test in various high temperature environments | Based on the principle of differential pressure method, gas transmission rate in various high temperature environments (5~150℃) can be determined for various materials such as plastic films, co-extrusion films, aluminum plating films, aluminum foil composite films. |
| Contact lens oxygen transmission performance test | Based on the principle of equal pressure method, Coulometric oxygen sensor is used to test oxygen transmission rate of contact lens. |
| CO2 transmission rate test by weighing method | Based on the principle of weighing method and with the reference of EN1062-6 method A, carbon dioxide transmission rate can be tested for various plastic films, co-extrusion films, aluminum plating films, aluminum foil composite films, etc. |
| Water vapor transmission rate test by inverted cup method | Based on the principle of weighing method, water vapor transmission rate under certain temperature and humidity when in contact with water can be determined for all kinds of protective clothing, medical dressing, plastic films, co-extrusion films, aluminum plating films, aluminum foil composite films and other materials. |
| Non-destructive test for packaging seal performance | Based on the principle of vacuum attenuation method, micro leakage detection of all kinds of pharmaceutical packaging, such as vials, pre-charged needles, Kjeldahl bottles, ampoule bottles, infusion bottles, etc. can be determined. Micro leakage of pouches, cans, bottles and other food packaging can also be determined. |
| Multi-station packaging pressure test | The test is for sealing performance evaluation of food, cosmetic products and other pouches under certain pressure; 5 station design. |
| Tensile test of packaging materials with ultra-long elongation | It is for testing the ultra-long elongation of plastic films, composite materials and flexible packaging materials; the stretching stroke exceeds 1200 mm. |
| Heat-seal strength test for cap films of medical bottles, yogurt cups and jelly cups | It is used to test the heat-seal strength of cap films, yogurt cups or jelly cups. |
| Test for stripping force of oil barrel anti-theft cover, opening force of internal pull ring and handle drawing force | The test is for oil barrel anti-theft cover stripping force, inner ring opening force, handle drawing force test. |
