PET Hotfill bottles
PET packaging for filling hot foods
Hot filling is a filling technology that has been tried and tested for many years and enables products to be filled in a microbiologically safe manner.
This method is particularly suitable for fruit juices, sauces, soups and ketchup.
Our Hotfill (HF) bottle series are specially developed for filling hot products at up to 87 °C.
The pet hotfill blowing process
PET hot filling
In the PET hotfill blow moulding process, heat is applied to the PET to create crystallisation in the molecular structure. This crystallisation makes it possible to fill hot liquids without the bottle shrinking uncontrollably.
The transparency of PET is retained despite crystallization.
HOTFILL TECHNIQUES for PET bottles in comparison
PEt standard hotfill technology with ring structure
Conventional PET hotfill bottles are equipped with so-called panel or ring structures to compensate for the volume contraction of the product after cooling.
Properties PET-STANDARD-HOTFILL technology
- mostly sleeved
- Higher bottle weight
Paneless PET hotfill technology without ring structure
In order to use hotfill bottles without a ring structure, nitrogen is added during the filling process. The resulting pressure build-up prevents the bottles from contracting in volume when the hot products cool down.
This enables the use of hotfill bottles without a ring structure or panels.
Advantages of PANELESS PET-HOTFILL technology
- smooth outer surfaces
- Simple labeling
- low bottle weight
- great design freedom
- optics like a cold aseptic bottle
