Hot filling in PET bottles is a safe filling technology that has been known for many years. Hot filling allows fruit juices, among other things, to be filled in a microbiologically safe way.
Our HOTFILL (HF) bottle series are suitable for filling food at temperatures of up to 87° Celsius.
In the PET hotfill blow moulding process, the plastic is heated to temperatures of up to 150° C in the blow mould. This causes crystallisation in the molecular structure. This crystallisation makes it possible to fill hot liquids without the bottle shrinking in an uncontrolled manner.

- paneless PET hotfill technology
- PET standard hotfill technology
- for filling up to 87 ° hot products
- microbiological | safe | filling
- up to 50 % rPET possible
Als PET-Experte haben wir uns auch auf die Hotfill-Verfahren und Techniken spezialisiert, so dass wir Ihnen beide Hotfill-Verfahren anbieten können. Paneless-Hotfill und Standard-Hotfill.
Both processes offer different advantages and properties:
Advantages of Paneless Hotfill technology
SMOOTH EXTERIOR SURFACES
SIMPLE LABELLING
LOW BOTTLE WEIGHT
GREAT DESIGN FREEDOM
OPTICS LIKE A COLD ASEPTIC BOTTLE
Properties of the standard hotfill technology
MOSTLY SLEEVED
HIGHER BOTTLE WEIGHT
Conventional PET hotfill bottles are designed with so-called panel or ring structures to compensate for the volume contraction of the product after cooling.
