In the paint packaging industry, labeling can be done either before or after filling the buckets. However, applying labels to an empty container offers a number of practical, technical, and financial advantages that are often overlooked.
Labeling a full bucket: a complicated approach
Extra weight slows down production
Once filled, a paint bucket becomes significantly heavier. For example, a 10-liter metal can weigh around 3 to 4 lbs when empty, but jumps to 30 to 37 lbs when full depending on the paint’s density. This added weight slows down the packaging line and requires more robust equipment.
For operators, handling heavy containers all day can quickly become physically demanding. Without proper ergonomic tools, it increases fatigue, slows down productivity, and raises the risk of musculoskeletal disorders.
The handle gets in the way
Most paint buckets come with a metal handle, which can interfere with the rotation required for accurate label application. If the handle is poorly positioned, it can interrupt the labeling cycle. The only solutions are to manually reposition the handle for each container or to use a machine equipped to automatically lift and hold it in place, both of which add complexity and cost to the line.
Why label before filling?
Simpler, more cost-effective machines
Labeling systems designed for empty buckets are typically more compact, easier to use, and require fewer customizations. This reduces investment costs, maintenance needs, and downtime—making it a smart move for any production setup.
Smoother handling
Empty buckets are lighter and more stable, making them easier to handle and transport on the line. Labeling becomes faster and smoother, and operators benefit from a more ergonomic and less strenuous workflow.
Cleaner surface = better labeling
When labeling is done after filling, paint drips or splashes can contaminate the surface of the bucket, leading to poor label adhesion, peeling, bubbles, or visual defects. Labeling clean, dry containers before filling ensures optimal application quality and a polished, professional appearance.
