The test strip containers produced by the test strip manufacturers use most of the packaging used for blood glucose test strips, urine test strips, and other test strip packaging. Common test papers have high requirements for moisture-proof and sealing oil of the packaging. Therefore, desiccant cap can effectively prevent the test strip from being damp, extend its shelf life, and can also prevent the test strip from directly contacting the desiccant.
test strip packaging
When choosing a desiccant, the test strip container manufacturer usually uses silica gel desiccant and molecular sieve as the main material. Silica gel desiccant is a highly active adsorption material, usually prepared by reacting sodium silicate and sulfuric acid, and after a series of post-treatment processes such as aging and acid foaming. Silica gel is an amorphous substance, and its chemical formula is mSiO2. nH2O.
Molecular sieve desiccant is a synthetic desiccant product with strong adsorption to water molecules. The pore size of the molecular sieve can be controlled by the different processing technology. In addition to adsorbing water vapor, it can also adsorb other gases. In the case of high temperature above 230℃, it can still hold water molecules well.
The proportion of desiccant in the bottle cap of the test paper barrel manufacturer is mostly (4:6), but it can also be reasonably adjusted according to some special conditions of the test paper to achieve better moisture resistance.
