Pack formatsWhat measurements are needed to specify machinery for tubs?
Practical guidance for tubs: capture samples, dimensions, output, acceptance tests and site constraints before buying.
Read the answer →What normally controls the result?
A pack must remain clean, stable and correctly orientated through every transfer, filling, closing, labelling and inspection stage.
- Dimensional and material variation
- Base stability and centre of gravity
- Neck, opening or sealing geometry
- Surface condition and static
- Guides, transfers and pack support
Information that makes a recommendation more accurate
- Dimensioned pack drawing
- Minimum and maximum pack samples
- Material and supplier specification
- Closure or seal components
- Required orientation and label area
- Target line rate
