In short
5 Gallon Water Bottle: what to know
Reusable 3- to 5-gallon water bottles are usually made from PC or similar transparent resins on a dedicated accumulator-head machine. Tongda’s TDB-25APC is built for this product, with material drying, plasticizing and the bottle mold planned together.
The TDB-25APC range is intended for 3–5 gallon water bottles. Specify the exact resin grade, bottle geometry, neck and handle before choosing the screw, die head and process settings.
Typical products
- 5-gallon (18.9 L) water bottles
- 3-gallon water bottles
- Handled and non-handled water jugs
Materials
- PC
- Tritan
- PE (with a suitable configuration)
Production process
How the production line works
- Step 01
Dry the resin
PC is hygroscopic, so it is dried to the supplier’s specification before processing.
- Step 02
Plasticize
The screw and heating zones melt the resin without degrading its clarity.
- Step 03
Accumulate and extrude
The accumulator head pushes out a heavy parison quickly for an even wall.
- Step 04
Blow and cool
The bottle is blown in the mold and cooled until stable.
- Step 05
Trim the neck and base
Flash is removed and the neck finish is checked for cap fit.
- Step 06
Inspect
Weight, clarity, wall thickness and leak tightness are checked before packing.
Selection guide
Choosing a machine
Bottle design
Volume, neck, handle and base geometry define the mold and the parison.
Drying and auxiliaries
Dryers, loaders and chillers are part of a stable PC line.
Quality checks
Agree clarity, weight tolerance and leak testing before the machine is configured.

Questions from buyers
FAQ
Didn't find your answer?
Ask our engineersWhich Tongda machine makes 5-gallon PC bottles?
The TDB-25APC is the dedicated model for 3–5 gallon water bottles, with PC and Tritan configurations available.
Can the same machine run PE water bottles?
PE bottles need a different screw and process settings. Share the resin and bottle design so the configuration can be confirmed.
Why does PC need drying?
PC absorbs moisture, which causes defects in the finished bottle. Drying to the resin supplier’s specification is part of the line.
