KSY extrusion blow molding machines produce sauce bottles, jars, edible oil and juice bottles from 10 ml to 6 L in HDPE and PP, with multi-layer EVOH barrier options for products that need a longer shelf life.
Extrusion blow molding suits food bottles that need a squeezable wall, a handle or an oxygen barrier layer, which stretch blow molded PET cannot provide.
Squeezable ketchup, mayonnaise and dressing bottles in PP or multi-layer structures.
Jam, honey, nut butter and seasoning jars with accurate neck finish for induction seals.
Handle bottles for cooking oil and HDPE bottles for juice and dairy drinks.
Choose by container volume first, then decide whether the product needs a barrier layer.

Liquid food bottles are leak tested before packing, and neck trimming gives the flat sealing surface induction seals need.
Pressure-decay testing catches pinholes and weak pinch-off welds before bottles are packed. Best suited to bottles that travel stably on a conveyor.
Leak testers →Removes neck flash and the dome left by blow-pin calibration on round bottles, leaving a flat, clean sealing surface.
Neck trimmers →Collates and bags regular round or square bottles automatically, cutting manual packing labor at the end of the line.
Packing machines →Carries bottles from the machine to downstream stations and returns flash to the crusher for recycling.
Conveyors →Food bottles and jars from 10 ml to 3 L are made on small extrusion blow molding machines such as KSY55 and KSY65. Edible oil handle bottles of 4 to 6 L run on the KSY75.
Sauces oxidize when oxygen passes through the bottle wall. A multi-layer bottle places an EVOH barrier between PP or HDPE layers, which blocks oxygen and extends shelf life while keeping the bottle squeezable.
Food-grade HDPE and PP are the standard materials for blow molded food containers. PP is chosen for hot-fill products, HDPE for milk, juice and oil, and PETG where a clear container is wanted.
Send KSY your container drawing, product type and filling temperature. We will recommend the machine, layer structure and mold design.
