Why we need certified reference materials? ã¯ï¿½ï¿½ for a long time, there is a blank in the reference materials for permeation testers in the industry, calibration lacks standrad (see the explanation of certified reference materials at wikipedia: https:en.wikipedia.orgwikicertified_reference_materials) ã¯ï¿½ï¿½ calibration verifies that the instruments operate at a specified set of parameters and are properly calibrated. Traditional way of data comparison is time-consuming and not accurate. Calibrate instruments with a standard material will be much more convenient and more reliable ã¢ï¿½ï¿½? how gbpi developed these certified reference materials? ã¯ï¿½ï¿½ spent more than 5 years ã¯ï¿½ï¿½ set and kept standard environment for film preparation and testing ã¯ï¿½ï¿½ conducted trails for more than 1000 times (with 1666 groups totally 5000 pieces of samples) ã¯ï¿½ï¿½ obeserved the filmsã¢ï¿½ï¿½ stablity for more than 6 months ã¯ï¿½ï¿½ finally made out films with stable and accurate permeation rate and low expanded uncertainty ã¢ï¿½ï¿½? how can gbpi offer these certified reference materials at such attractive price ? ã¯ï¿½ï¿½ we master the core techniques, so we can produce these films by ourselves ã¯ï¿½ï¿½ we build stable longterm partnership with our film-making supplier, so we can get the best discount, and finally lower your cost

Heat seal property is the most important property of the plastic packaging film. Gbb-p heating-seal tester can measure the temperature range, intensity, suitable speed, pressure and so on of the heat sealing of plastic film based material, flexible packaging composite membrane, coating paper, aluminum foil and other kinds of heat-sealing compound precisely. Instrument structure: the structure of the model gbb-p heating-seal tester is composed of 4 parts: pneumatic drive system, heat-sealing equipment, temperature adjustment system and time adjustment system. Pneumatic drive system: it includes pressure gauge, guide stick, cylinder, pneumatic valve, pressure regulating handle and so on. You can pull the pressure-regulating handle outward, rotate to the right side to adjust the heat sealing pressure to a high value, and rotate to the left side to reduce it. After setting the pressure, please press the handle to the side of mainframe to lock the air pressure. Heating-seal device it is composed of the upper and lower heat-sealing sticks, of which the upper one is connected with a cylinder. There is an insulating plate in the upper part, which can prevent heat transmit to the cylinder. The heat-sealing stick is made of aluminum, and the center is heater. There is a silica gel plate in the upper part of the lower heat-sealing stick, which can mitigate pressure impact during heat sealing. Temperature measurement system was installed at the back of the heat-sealing stick. Temperature adjustment system: the upper temperature controller controls the temperature of upper heat-sealing stick, and the rear temperature controller controls the temperature of lower heat-sealing stick. The temperature can be set at will through adjusting the button on the dial plate.
