The PET bottle impresses with its stable shape and is equipped with barrier blockers to keep CO2 inside and oxygen out. A PET bottle weighs 560 g less than a glass bottle. The CO2 footprint has fallen by more than half to just under 1 kg of CO2 per bottle. In addition, lorries can now make full use of all pallet spaces with filled bottles - previously this was only possible for two thirds of the space due to the high weight of the glass. As many factual advantages as the PET bottle offers, the end consumer has so far been slow to accept it. “So far, the industry has been trying to convince traditional sparkling wine and wine buyers to switch to PET bottles,” says François Desfretier. “I think producers need to appeal to environmentally conscious target groups - with innovative marketing and perhaps also new products such as non-alcoholic variants or mixed drinks.” Innovation also outside the beverage sector It is not only in the beverage segment that PDG is showering the industry with material- and CO2-saving technologies. A new PET ketchup bottle will soon be launched on the market. It is 20% lighter than conventional polyolefin bottles and offers a 40 times better oxygen barrier. As a special highlight: the end consumer can see the product. www.pdg-plastiques.com For large containers, PDG is reducing the material thickness in the base area via MINT-TEC technology.
