EDITOUR PETplanet Insider Vol. 26 No. 10/25 www.petpla.net 10 Saving material on the floor is sustainable Customer satisfaction is always the top priority for François Desfretier, Managing Director of PDG Plastiques. His customers don’t just come to PDG with standard enquiries - they also approach him with projects that other converters don’t really dare to tackle. PDG has built up a highly specialised machine park for this purpose. In addition to the 20 Netstal systems, there will also be one of the first Otto Systems units for preforms of large-volume containers with 16 cavities, a small 1Blow machine with two cavities for small batches with a new technology for moulding deep recessed grips in the containers. Also in use is a SIPA system for sparkling wine and wine bottles - to name just a few examples. But first things first: Editour Interview with PDG Plastiques // April 8, 2025 We met: François Desfretier, CEO PDG, Philippe Blonda, Business Development Material supply: complexity from the first step This is where the complexity of the process begins. Many preforms and bottles contain different proportions of rPET. This is mixed with new material in a mixing station (see image above) according to the desired proportion and then passed on to the dryer. François Desfretier, CEO of PDG, would like the industry to agree on fixed rPET percentages - for example 25%, 50% and 100% - and for the material to be supplied ready-mixed by the raw material manufacturer. In the long term, he sees chemical recycling as the solution, as it ensures less contamination and guarantees consistently high material quality. State-of-the-art logistics: round the clock versatility of AGVs Five AGVs (Automated Guided Vehicles) have been handling inhouse logistics since 2024. They move along fixed routes or with the help of modern navigation technologies such as laser scanners or SLAM (Simultaneous Localisation and Mapping). The AGVs can change their batteries independently and are therefore ready for use around the clock. Weight saving with large containers For the large 20 L containers, PDG is now reducing the material thickness in the base area. The new preform weighs just 372 g instead of the previous 485 g, i.e. almost 25% less. This technology takes material out of the base of the preform. The idea comes from ReduPET and CPS (Creative Packaging Solution): with the help of mint technology, after the preform has left the mould, the injection point is reshaped again in the post-cooling station using a deep-drawing process (see image below). Sponsors to date The classic preform cavity can be clearly seen in the open mould as well as the lighter head area - on the mandrels of the post-cooling - which is formed by minting thermoforming.
