Overview of testing methods for oxygen barrier performance of cosmetic hose
The standard GB T-'Test Method for Oxygen Permeability of Packaging and Containers' promulgated and implemented on the year, month and day introduces the standard test method for measuring the oxygen permeability of dry packaging with a coulometric sensor. The following is a brief introduction: First, fix the tube to be tested on the test fixture with a sealant. After a period of time, the sealed sample is fixed on the test equipment. The air in the pipeline is slowly swept by the nitrogen flow, and the outer surface of the pipeline is in an environment with a known oxygen concentration, that is, an indoor environment with an oxygen content of .% or an environment with an oxygen content of %. The oxygen enters the nitrogen carrier gas through the pipeline, and is carried to the Coulomb electric sensor along with the nitrogen carrier gas. The oxygen passing through the sensor will generate a current, which is proportional to the amount of oxygen carried to the charge sensor per unit time. Therefore, the oxygen transfer rate of the entire tube can be obtained, and the shelf life of the product can be better determined. If cosmetics come into direct contact with human skin, their quality will directly affect human health. In order to ensure product quality, service life and product life, it is very important to test the air permeability of the rubber tube sheet and the forming tube. The oxygen transmission hose specified in the standard 'GBT-Co-extruded Multi-layer Composite Hoses for Cosmetics' shall be tested in accordance with the test method specified in this law. cm(m•h•.MPa). The above is the method for testing the oxygen barrier performance of cosmetic hoses, which plays a very important role in cosmetic packaging and is also an important reason for the superior performance of cosmetic hoses.
The rise of the beauty economy has caused cosmetic brands to pay more and more attention to appearance packaging.
