The target was to develop a new container shape for a vinegar glaze. The new packaging was requested to be more appealing and also squeezable for a better handling by the fi nal customer.
Conversion from HDPE to PET was done to improve aesthetic, to be free to create new shape and to enhance mechanical and barrier performances.
Conversion from HDPE to PET
Development and Challenges
All started reviewing existing HDPE design: the HDPE bottle was opaque with no glossiness nor shiny effect. Also transparency was an issue because the content was not visible.
HDPE is rigid and the container was diffi cult to squeeze, moreover its mechanical features don’t allow freedom in shape creation. The conversion to PET overcame all the limits of the old material allowing for the creation of an attractive shape with shiny and transparent surface, easy to handle and to squeeze for easiness in gastronomic preparation.
No special blow-moulding issues occurred and only special attention was paid on orientation features of the champagne base.
