Interested in filling hotfill products into PET bottles with greater cost-efficiency? And improving their appearance into the bargain? Of course you are! After all: Hotfill drinks in PET bottles are an expensive luxury where bottle weight and process costs are concerned. And the bottles’ panel design is hardly a sight to behold.
Optimise your production costs in the hotfill process by using panel-free PET bottles. With the Krones NitroHotfill process you will not only reduce the material costs for your preforms. A higher station output on the blow moulder and a lower energy requirement will also have a notable impact on your budget. But that’s not all: Bottle appearance limitations are now a thing of the past, replaced by full freedom of design without any panel compensation areas.
Raise your hotfilling into PET bottles to a new level.
The blow moulder/filler block with NitroHotfill process is comprised of a Contiform H stretch blow moulder and a Modulfill filling system with hot return. Connected in between is a bottom base cooler for stabilising the PET bottle base.
