Medicinal plastic bottles air tightness test is very important

Medical plastic air tightness for drugs in the period of validity of be affected with damp be affected with damp, metamorphism is important, but also prevent light, heat, oxygen and other important media's influence on the drug. So as a medicinal plastic bottles production enterprise, we attach great importance to its air tightness test. What is a medicinal plastic bottles air tightness? Simply according to relevant national standards for testing, such as detection of capsule of plastic seal reliability is a certain number of capsule plastic bottles, in each bottle in a little plastic balls, tighten cap method. And then put it in container with suction device, water immersion, vacuum and vacuum degree for 27 kpa, lasts for 2 minutes, can not have water bottle or take a bubble phenomenon. Capsule after index, of course, to ensure the tightness of plastic, also need some other economic indicators, such as sex, wet oxygen resistance and control, to ensure that the shelf life of the product quality. Also has launched in the market now seal tester machine, using the principle of vacuum cleaner vacuum chamber, make medicinal plastic bottles submerged in the water samples in the production of internal and external pressure difference and look inside the sample gas to escape, to determine the sealing performance, or through the vacuum of the vacuum chamber, make sample production pressure difference inside and outside, to observe the inflation of the sample and release the samples after the vacuum in the shape of a recovery, in order to determine the sealing performance.
