Bottle Formats
Bottle Format Changeover Requirements for Filling Lines
What buyers should define for bottles, caps, labels, coding, packing, recipes, and change parts before ordering a multi-format line.
A line advertised for several bottle sizes may still require different molds, star wheels, guides, cap handling parts, label settings, conveyor adjustments, and packing recipes. Buyers should define every planned format before ordering and confirm which change parts are included.
Create a bottle-format matrix
| Format input | Details to provide | Equipment affected |
|---|---|---|
| Bottle | Volume, height, diameter, neck finish, material, drawings and samples | Blower, air conveyor, rinser/filler/capper, conveyors |
| Cap | Type, dimensions, thread, material, color, liner if any | Cap elevator, sorter, chute, capping heads |
| Label | Sleeve, OPP, self-adhesive, dimensions, roll direction, position | Labeler, inspection, shrink tunnel |
| Code | Content, position, ink or laser requirement | Coder bracket, trigger, inspection |
| Pack | Bottles per pack, arrangement, film or carton, handle, tray | Collator, shrink packer, cartoner, conveyors |
Ask for a change-parts list
The quotation should identify common parts and format-specific parts for each SKU. Ask which adjustments are tool-free, which require hand tools, which values are stored in recipes, and which parts need replacement. Confirm storage, labeling, and identification of loose change parts.
Test representative formats
Testing only one easy bottle does not demonstrate the full format range. If several formats matter commercially, choose at least the smallest, largest, or most difficult formats for sample trials or acceptance testing. Provide production-grade bottles, caps, labels, and packing material early enough for the supplier to test them.
Define changeover acceptance
- Required staff and tools.
- Target changeover sequence and estimated duration.
- Correct recipe selection and parameter records.
- First-off bottle checks for fill, cap, label, code, and pack.
- Restart stability and rejected material during adjustment.
Confirm upstream and downstream consequences
A new bottle format may also change preform heating, blow-mold cooling, air-conveyor neck handling, fill height settings, cap sorting, label roll size, shrink-tunnel settings, pack arrangement, pallet pattern, and warehouse dimensions. Review the whole line rather than asking only whether the filler can accept another bottle volume.
Plan change-part management
Format parts should be permanently identified, matched to a format list, protected from damage, and stored near the line. Request drawings or part numbers for replaceable items and confirm whether the buyer can reorder individual components. Include wear parts, sensors, guide components, and dedicated tools in the spare-parts discussion.
Train with a written sequence
Operator training should cover shutdown, removal, cleaning, installation, mechanical adjustment, recipe selection, trial production, quality approval, and return to normal operation. Record the sequence with photos or a short video. A repeatable procedure reduces dependence on the one technician who remembers the original setup.
