![]() ![]() This solution is perfectly in keeping with a circular economy approach.” says SGT. “We have extended our specific offer to ultra-fresh products by proposing this cup preform dedicated to yoghurts and fresh desserts in response to market demands. The new application has been developed as part of SGT’s continuous improvement approach: SGT states: “It is clear to see that today PET is the material which can be converted the most, is suitable for food contact, is 100% recyclable and which responds precisely to new European sustainable consumption requirements.” SGT’s cup PET preform meets new European single-use plastic directives since it can contain up to 100% rPET and is 100% recyclable. Since glass generates more CO2 emissions when it is manufactured and transported, compared to PET, it is a less eco-responsible solution. This PET yoghurt pot version also seeks to replace glass jars which are much heavier (80 g compared with 11 g for its plastic equivalent). It enables an unbreakable pot with a lid to be blown. The cup preform that SGT is proposing is claimed to be light and transparent. SGT has developed a recyclable alternative to polystyrene (PS) yoghurt and dessert cups that may integrate up to 100% rPET. This specific feature enables better bi-axial orientation and therefore better distribution of the material.įinally, the preform may be customised and provides the possibility of integrating a handle. The SGT group’s R&D department set itself a real technical challenge by developing a shorter version of the “5-gallon”, compatible with all injection press and blower models. In comparison to developments in PC, the 5-gallon PET alternative is claimed to be more eco-responsible as PET is a reliable and robust material which is suitable for food contact – and it is recyclable. SGT points out that the gallon bottles respond to current market demands since today it is not only companies who use large water bottles but also private customers who no longer want to buy, carry and store packs of water bottles. SGT’s “refill” preforms are both reusable and recyclable. The development of the “refill” preform is in keeping with the Group’s 3 R strategy: SGT is committed to Recycling, through its SGR unit, to Reducing the weight of its preforms and now to project to Re-use plastic packaging. It provides a response to current economic and environmental objectives. The bottle obtained is consignable, reusable, refillable and recyclable. The PET “refill” preforms are designed as an alternative to polycarbonate solutions for water fountain bottles. ![]() The ovoid preform base enables the bottoms of the bottles to be lightened after blowing. The 55 mm preform neck has been specially designed to guarantee a perfect seal. This not only saves material costs but also transport costs. Its weight has also been reduced from 730 g to 650 g for the 5-gallon version, and 450 g for the 3-gallon one. This preform, which was already available but has been improved, has been completely re-imagined in terms of its design and geometry: 33% shorter than most 5-gallon preforms currently on the market, it optimises bi-orientation, obtains a better stretching and blowing ratio and prevents the bottle from crystallising, with no compromise on the quality and robustness of the packaging, states SGT. The 3- and 5-gallon refill preforms for water bottles have been developed by SGT for the re-use market. While some, such as the preforms for 3 or 5 gallon containers, have been further developed and improved, the company is also introducing new projects like the 24/410 neck preforms dedicated to cosmetic and personal care applications. French Société Générale des Techniques, SGT, offers a wide range of preforms. ![]()
