Water Bottling Machine Suppliers & Manufacturers

Water bottling machines fill treated water (still or carbonated) into PET bottles, apply caps, label, and package for distribution. The water bottling line may be configured as: separate machines (depalletiser/bottle unscramblee, rinser, filler, capper, labeller, case packer, palletiser) linked by conveyors; or a monoblock (integrated rinser-filler-capper in one machine), which is more compact and more hygienic for water products. Blow-fill-cap (BFC) monoblock or inline blow-fill-cap: the most hygienic and efficient configuration for high-volume water bottling; the PET preform is heated in an oven, then blown into the final bottle shape in the blow moulding section, immediately transferred to the filling section (without exposure to the environment), filled with water, and capped — all in one integrated machine; the bottle is never exposed to the outside environment between blowing and capping, minimising contamination risk; the standard configuration for large-scale water brands. Separate blow moulder + filling line: the PET blow moulding machine is separate from the filling line; blown bottles are conveyed via an air conveyor to the filling monoblock; more flexibility for running different bottle designs and changing bottle formats; suitable for medium-to-large scale operations. PET preforms — the raw material for blow-moulded PET water bottles; preforms are injection-moulded PET parts that are heated and blown into the final bottle; preforms are sourced from preform manufacturers and stored at the bottling plant. Still water filling: still (non-carbonated) water is filled using gravity, volumetric, or flow-meter fillers; filling is straightforward as the product is non-carbonated and non-viscous; filling speeds of 10,000–100,000+ bottles per hour are standard. Sparkling water filling: carbonated water is filled using an isobaric (counter-pressure) filler — the bottle is first pressurised with CO₂, then the carbonated water is filled against the CO₂ back pressure to prevent loss of carbonation; the filling head seals before the bottle is de-pressurised after capping.

PET water bottles are produced from PET preforms (sourced from injection moulding operations) that are blown into the final bottle shape using a stretch blow moulding machine. Key components of a water bottling line: PET preforms — sourced from preform manufacturers; preform weight determines the bottle wall thickness; common weights: 10–14g for 0.5L water bottles; 18–25g for 1.5L bottles; 28–35g for 2L bottles; lighter preforms (lightweighting) reduce plastic consumption. Stretch blow moulding machine — heats the preform and blows it into the final bottle mould; output speeds of 1,000–3,500 cavities per hour per mould cavity (a 16-cavity machine at 2,000 BPH per cavity = 32,000 BPH). Closure — standard PET water bottle caps: 28mm PCO 1810 or 28mm PCO 1881 neck finish; the cap and neck standard must match across the blow mould, preform, and capping machine. Labelling — OPP pressure-sensitive labels or sleeve labels for water bottle branding; for water brands emphasising sustainability, paper-based or reduced-plastic labels. Water treatment — the water supply must be treated (filtration, UV sterilisation, ozonation) before bottling; water treatment is an upstream prerequisite for bottling, not part of the bottling machine itself. Key water bottling machine suppliers: Krones (Germany), KHS (Germany), Sidel/Tetra Pak (France), SIPA (Italy), CFT Group (Italy), and a range of Chinese manufacturers for small-to-medium scale water lines. When sourcing, specify: still or sparkling water, target output (BPH), bottle size range, blow mould and preform source, cap type, label type, hygiene requirements, and secondary packaging format.
