Specify a Water Bottling Line Changeover Before You Order

An approved bottle list is not a tested changeover sequence. Record A to B separately from B to A because retained materials, tooling positions, preparation and verification can differ. Use drawing and recipe revisions for the bottle, closure, label and complete pack, not volume alone. For a new line, identify which transitions must be demonstrated before approval and which remain conditional on site conditions.

• If two formats share a neck finish, still verify the bottle body, transfers, labeling and final pack at the agreed output condition.
• Identify supplied change parts and required adjustments or engineering changes at each affected machine.
• A new supplier, drawing revision or pack arrangement can invalidate part of the previous evidence; name the affected checks rather than assuming automatic compatibility.

Choose one physical line-end count point for the last accepted old-format unit and the accepted new-format output. Record first material through the machine, first accepted unit and return to the agreed sustained condition as separate milestones. Define how long and under what quality conditions the new output must remain stable; there is no universal duration for every project.

• State whether the claim covers only mechanical work or the whole transition, including clearance, recipe checks, first-off approval and recovery.
• Name staffing, prepared parts, tools, material readiness and any temporary factory setup used during the test.
• List required hygiene and safety activities openly. Do not remove them to match a faster headline time.

The checklist below separates a stated feature, a testable condition and the evidence still needed. A tool-free adjustment or automatic recipe can be useful, but its value depends on whether that activity limits your complete transition. Keep claimed, demonstrated and not-tested results distinct; an untested direction should not inherit another direction’s result.

• Request the actual transition timeline and count/quality records, not only a video of one machine adjustment.
• State which formats, crew, parts and machine interfaces the proposed changeover option covers.
• Agree how deviations are corrected and retested before treating the claim as an accepted performance condition.

Start with the two SKU identifiers, drawings or non-confidential dimensions, closure and label details, bottles per pack, retained equipment and the change frequency you expect. Add required accepted output and any supplier claim you need to verify. If the line already operates, include a measured transition record; the improvement guide explains how to find the limiting tasks.

• Mark unknown parts, timings and approvals as unknown; do not fill them with estimates presented as measurements.
• Separate the required result from the supplier’s current evidence and proposed options.
• The next step is a project-specific performance discussion, not a universal promise that every size runs on the same setup.
