A sparkling wine bottle in PET, designed and produced by processing technology and container design company SIPA, brought the company top prize in the 2023 Best Packaging contest held during Milan Design Week in April. The award came from a panel headed by Professor Valeria Bucchetti, coordinator of the Communication Design course at Milan Polytechnic University. The panel concluded that the bottle led the field in meeting strict criteria for Quality Design.

Sparkling wine bottles already in PET
This is not only a highly innovative concept, with the potential to break down barriers in a new and exciting market for PET. A French bottle maker recently began commercial production of PET bottles for a major Italian wine maker, using molds and stretch-blow molding equipment from SIPA.

Better costs
PET offers producers of all types of wines – still as well as sparkling – important economic and environmental advantages. In the recent past, for example, diverse supply chain problems, including spiraling costs for energy and raw materials, have made glass bottles for wine harder to find and much more expensive to buy than they used to be. A wine maker wanting glass bottles today could easily have to pay 30% more than they did in the past.

SIPA’s Packaging Development Team has developed a product that is perfect for replacing traditional glass bottles. Wine companies can make the change no cost, since extensive tests have proven that PET bottles can run on filling lines designed for glass bottles.

Looks the same, but much lighter
A key part of the SIPA innovation is the bottle neck, which looks just like the glass version, meaning that it accepts the classical mushroom-shaped cork with its metal cage. The base also looks the same as the original. The design provides a top-load resistance of 350 Kg.

Sparkling wine consumers will enjoy the same sensual experience with the new PET bottles as they always have done with glass ones, from uncorking to pouring. But they will most likely notice that the PET versions are much lighter, at just 90g, and virtually unbreackable. That is also great for operators along the changing supply chain, as sales via e-commerce and home delivery continue to rise.

Lower carbon footprint
It is also worth noting that the dramatic difference in bottle weight will have a positive impact on CO2 emissions, due to more efficient logistics with their 88% weight reduction.
