Graining on bottles is a process that involves applying a textured pattern, often resembling wood grain, to the surface of the bottle. This technique adds visual interest and a unique tactile feel to the bottle, enhancing its overall aesthetic appeal. Graining on bottles can be achieved through various methods, such as screen printing, hot stamping, or embossing. These processes allow for the precise application of the grain pattern onto the bottle's surface, resulting in a realistic and eye-catching effect. Graining is commonly used in the packaging industry for Glass bottles, spirits, and other luxury products, as it adds a touch of sophistication and elevates the brand's image.
