1L Milk bottle with DCU. The alternative to HDPE and carton for Milk
THE PROJECT
To develop an alternative monolayer PET bottle to alternative to multilayer HDPE and carton for ESL and UHT milk to decrease the production cost.
THE SOLUTION
P.E.T. Engineering and Novapet, in collaboration with Husky Injection Molding Systems, work together on barrier materials and additives to make PET be the most suitable material for any liquid product, especially for sensitive ones which require full light prevention to preserve all the properties and taste.
At the same time, P.E.T. Engineering is focused on the reduction of production costs while maintaining a high mechanical performance of the container.
The result of this cooperation is an ultra-light bottle for milk weighing only 19.5g for extended shelf life milk and 21.5g for UHT, which means, respectively, 15.2% and 10.4 % less than the weight of the lightest containers currently on the market.
This new light-weight, together with a combined study on preform and container, comes also from the use of DCU, an alternative to multilayer preforms currently used in the dairy industry. DCU, by Novapet, allows the same barrier performance of a multilayer preform but with lower machinery costs because it is an additive that can easily be added to PET using a single-stage process. The great simplicity of its injection process leads to a reduced production waste and the light-weighting permits less production costs per bottle. From today the
monolayer PET bottle is a real alternative to multilayer HDPE and carton for ESL and UHT milk.
The 1L milk bottle with DCU was among the finalist in the Best packaging innovation category in the 2014 World Dairy Innovation Awards.
