Physical and chemical performance test of plastic medicine bottles

The main items of physical and chemical performance testing of medicine plastic bottles are heavy metal test, non-volatile residue test, ignition residue test, reducing substance test, sealing performance test, oscillation performance test, water vapor permeability test and abnormal toxicity test. And bacterial culture tests, etc.

Among them, the effervescent tablet packaging pays more attention to the water vapor transmission rate, and the sealing performance and the ignition residue are the most common two inspection methods for the existing medical packaging. The water vapor transmission rate actually contains two meanings of water vapor permeation and water vapor transmission coefficient. These two meanings also have certain meanings, but they can all be used to indicate that water vapor is transmitted through a certain material. ability. The amount of water vapor permeation indicates the weight of the water vapor permeating material at a certain temperature and humidity for a certain period of time. The water vapor transmission rate is a standard value of the water vapor transmission amount converted by the coefficient, and corresponds to a standard unit for comparison between different test results. After the organic drug is decomposed by carbonization or inorganic drug, it is moistened with sulfuric acid, firstly ignited at a low temperature and then at a high temperature (700~800 °C), so that it is completely ashed, the organic matter is decomposed and volatilized, and residual non-volatile inorganic impurities (mostly metal oxidation) The substance or inorganic salt) becomes a sulfate, which is called a burning residue.
