On February 28th, Prof. Xiao Xing from Tsinghua University visited GBPI Guangzhou for a visit, exchange and lecture, and was warmly received by GBPI Chairman Zhou Xue Cheng and Sales Director Yang Vivi from Foreign Trade Department 1.     GBPI Chairman Zhou Xuesheng led Professor Xiao to visit the barrier performance testing instrument laboratory, basic instrument production workshop, digital laboratory, application scenario comprehensive exhibition hall and other venues. At the site, Chairman Zhou Xue Cheng explained the various series of instruments of Biaoji, a piece of instrument in which cohesion of technology and innovation, showing the advanced packaging material testing technology.       Afterwards, Prof. Xiao gave a speech on "Building a Moat with Technology and Operating a Business with Financial Thinking" at the conference. The atmosphere was warm and the applause was incessant, and this speech benefited GBPI employees greatly. As an expert professor with high reputation in academic field and corporate governance field, Prof. Xiao Xing has brought GBPI cutting-edge information on corporate management and innovative development ideas, which has broadened the way forward for GBPI. GBPI, with the attitude of continuous learning and progress, will forge ahead and gather solid strength from all walks of life to make packaging better!

GBPI at IPF Bangladesh, We are attending the 15th IPF Bangladesh INT'L PLASTICS, PRINTING & PACKAGING INDUSTRY FAIR. Welcome to GBPI booth NO.446 for discussion!   Last year IPF gathered over 460 exhibitors from 19 countries and areas, namely Australia, Austria, Bangladesh, China, Egypt, Hong Kong, India, Indonesia, Italy, Japan, Pakistan, Singapore, South Korea, Taiwan, Thailand, Turkey, United Arab Emirates, United States and Vietnam. Meanwhile, more than 26,639 professional buyers visited the show, boosting the trade fair to a brand new horizon. IPF gathered over with its scale expanding steadily year on year. Currently Bangladesh exports plastics products to different countries, including the USA, Canada, China, India, Nepal and the European Union, plus the government will set up a dedicated industrial zone in Munshiganj to promote environment-friendly plastic industry. The Executive Committee of the National Economic Council (Ecnec) approved the Tk 133-crore project, slated for completion by 2018.  

Xin Nian Hao! May good fortune be abundant this Chinese New Year. GBPI is grateful for the meeting in 2022, looking forward to our 2023

Abstract: Water vapor transmission rate is an important performance index to characterize the solar backsheet's barrier performance to external water vapor (moisture), which directly affects the working condition and service life of solar cells. This paper uses the W413 2.0 infrared water vapor transmission rate tester developed by Guangzhou Biaoji Packaging Equipment Co., Ltd. to test the water vapor transmission rate of solar backsheet samples, and introduces the test standard, test process and test results for reference of major enterprises in selecting water vapor barrier testing equipment and test methods. In the field of solar photovoltaic power generation, solar backsheets play an important role. Usually, the solar backsheet is located at the outermost layer of the solar cell module's backside, thus playing a protective and supporting role for the solar cell module. The backsheet should have reliable electrical insulation, water vapor barrier, aging resistance, mechanical strength and toughness to keep the solar cell in the best working condition and maintain a service life of 25 years.Water vapor barrier performance is one of the important indicators to measure the performance of solar backsheet. If the solar backsheet has poor water vapor barrier performance, water vapor penetrating into the encapsulation system through the backsheet will affect the EVA bonding of the encapsulation film, causing the backsheet and the encapsulation film EVA to delaminate, causing the cell to be oxidized and thus seriously reducing the cell power generation efficiency and the service life of the module. As the solar cell set is placed outdoors for a long time, the humidity is greater on rainy days and water vapor has a greater impact on the solar PV module. Therefore, it is very important to conduct water vapor transmission rate test on solar backsheet to evaluate its water vapor barrier performance. 01 Testing standards The equipment used in this test is the W413 2.0 infrared method water vapor transmission rate tester developed by GBPI. The equipment is equipped with self-developed high-precision infrared moisture sensor, with ultra-high stability and ultra-low failure rate, wide range, high sensitivity, resolution up to 0.0001 g/(m2-24h); using semiconductor refrigeration chip two-way automatic temperature control technology, temperature control accuracy of 0.1 ℃; using dual airflow humidity method to control humidity, humidity stability, humidity accurate to ± 2% RH. Meanwhile, the instrument is equipped with 3 chambers, independent data, can meet the high throughput testing needs, high testing efficiency. This testing equipment conforms to many domestic and international standards such as GB/T 26253, YBB 00092003, ASTM F1249, BS EN ISO 15106-2, JIS K7129, etc.   Testing principle: W413 2.0 water vapor transmission rate tester adopts the principle of infrared method. The pre-treated specimen is fixed in the middle of the test chamber, and t...
