AN Italian bottle manufacturer has developed a hot-fillable PET ketchup bottle, with the end goal being to compete with aseptic filling.
The company claims its bottles will be a cost-competitive alternative as well as having aesthetic benefits also.
SIPA’s designers say they took an existing ketchup bottle, shortened the neck and softened the angles around the bottle’s body to prevent collapsing and provided an ‘attractive appearance’.
The new type of bottle requires a special PET resin suitable for the heat setting processes used for hot-fill containers. The resin also needs to contain an oxygen scavenger to stop the ketchup oxidising and discolouring over time.
According to SIPA, with a suitable scavenger the container can have a shelf life of at least 12 months.
