Why bottled water packs are different
Filled bottles can be heavy and tall, and the pack may need to remain stable through conveyors, sealing and tunnel shrinking. A bottled water shrink wrap machine therefore needs controlled infeed and a suitable shrink tunnel, not just a sealing jaw.
The machine choice depends on bottle size, pack count, tray use, film thickness and the output expected from the line.
Sleeve wrapper route
A sleeve wrapper can wrap PE film around the bottle group and then transfer the pack into a heat tunnel. The film tightens around the pack and helps hold the bottles together for transit or retail handling.
For automatic lines, consistent bottle spacing and pack collation are critical. If bottles arrive unevenly, the sleeve wrap and tunnel result will vary.
Quote data for bottled water lines
Provide bottle diameter, bottle height, pack count, finished pack dimensions, tray requirement and output target. A video of the existing line can also help where the bottle handling or collation method is already defined.
Lancing can use this data to advise whether a standard automatic sleeve sealer route is suitable or whether additional collation/infeed equipment should be considered.
Quote route and specification checklist
| Bottled water data | Quote value |
|---|---|
| Bottle size | Determines pack and tunnel dimensions. |
| Pack count | Controls collation pattern and film width. |
| Tray format | Changes stability through wrapping. |
| Line speed | Determines automation and tunnel dwell needs. |
