beverage filling machine for pet bottles Beverage Filling Machines | Custom Solutions for Water, Oil & More

A beverage filling machine for PET bottles is engineered to handle the specific characteristics of polyethylene terephthalate (PET) containers, which are lightweight, shatterproof, and the dominant packaging material in the beverage industry. These machines must accommodate the wide variety of PET bottle shapes and sizes, from small 200ml water bottles to large 2L soda bottles, and sometimes even 5-gallon large water containers. Key design considerations include gentle bottle handling to prevent tipping or deformation of the lightweight containers, especially during the transfer into the filling carousel. The filling technology itself depends on the product: isobaric (pressure) filling for carbonated drinks to maintain carbonation and prevent bottle distortion, and gravity filling for still products like water. For hot-fill applications (e.g., juices), the machine must be paired with a heat-set PET bottle designed to withstand the thermal stress and vacuum cooling process without paneling. Ace-Filling's fillers for PET bottles often feature automatic bottle height adjustment systems that adapt to different container sizes without manual intervention, minimizing changeover time. Furthermore, the entire conveying and filling process is designed to be as smooth and low-friction as possible to avoid scuffing or damaging the PET material, ensuring that the final product arrives on the store shelf with a pristine appearance.
