Some precautions when baking lead-free and chromium-free decals on glass bottlesIssuing time:2020-11-17 15:32 Many glass bottle storage jars are deeply processed for aesthetic purposes, such as silk - screening and flower - baking. However, in recent years, for glass jar containers exported to the European market, lead - and chromium - free decals must be used during the flower - baking process, which are harmless and pollution - free to the human body and the environment. Many glass bottle flower - baking factories bake glass jars with silk - screened and water - transferred decals together with lead - and chromium - free decals, which will directly affect the lead - and chromium - free products. 1. Whether it is printing or flower - baking, products containing lead and chromium and those without lead and chromium must be stored separately and not in the same warehouse. 2. When workers operate, the printing inks and machines must be in an independent and complete workshop. 3. After the glass containers are decaled, products containing lead and chromium and those without lead and chromium must also be stored separately during natural drying. 4. When entering the baking oven, do not bake them together. Otherwise, through high - temperature air convection, products containing lead and chromium will contaminate products with lead - and chromium - free decal patterns. |
