The Vietnamese word "đóng chai" means "to bottle" or "bottling" in English. It refers specifically to the process of putting a liquid, like beverages or sauces, into bottles for storage, sale, or distribution.
In more advanced contexts, "đóng chai" can also refer to the commercial aspect of bottling, such as marketing bottled products or the environmental impact of using bottles.
While "đóng chai" primarily refers to the act of bottling, it can also imply preserving or storing liquids in a sealed container.
