When designing preforms, a number of parameters have to be defined, like the overall shape, the neck finish and mechanical and barrier characteristics that need to be achieved. The length of the preform results from the bottle’s height (minus neck) as well as the axial stretch ratio, while the core diameter

First of all, a look back over the past 20 years: What developments have been particularly influential to your activities in the area of design/system manufacturing for preforms? Moraldo Masi, PET Business Director Closures, Containers & PET BU Sacmi: “For many years the main driver was product light-weighting, one of the

It is not working without: moulds The PET bottle is a product that has been optimised over the last years and is constantly evolving. Different development steps have to be led back thereby on mould technology which made it over the years possible to fulfil producers and customers inquiries. The requirements

A review of developments over the last 20 years Although we are primarily a magazine for the beverage industry, it was only a matter of time before the triumphal march of PET would prevail in other areas of packaging. Depending on the intended use, significant advantages such as lower manufacturing or

A desire for a plastics-free world has been identified by market research company Euromonitor as one of the top ten global consumer trends of 2019. In relation to PET however, the facts tell a different story: around 80% of the PET resin market still goes into more than 500 billion bottles

In this issue we focus on the manufacturers of inspection systems. We have asked them since when their company deals with inspection in the PET area (I), in which area of inspection they are active and where they see potential for further growth (II). We also asked them about their most

After looking back to the very beginning and some highlights of PET bottles, we also thought about future trends in PET bottles processing. We picked out some very new design and processing developments. Some topics come always in mind when thinking about PET bottle design today: less weight, the percentage of

A review of 20 years of meetings, talks and inspiration Technology is only as good as the people behind it. Lots of clever minds, from bottlers, processors and suppliers have made the PET bottle what it is today with their imagination and energy. We have come to know and appreciate quite

A large amount of air is needed to blow PET preforms into bottles. The compressors that compress atmospheric air into compressed air must withstand extreme conditions such as high pressures, heat and continuous operation. But the success of the blowing process depends on a consistent and clean flow of air regulated
