16 PET planet Insider Vol. 20 No. 06/19 www.petpla.net JUBILEE in the USA. The 0.5 l bottle weighed 10 g, and a 0.99 g cap amazed the experts . Graham Packaging presented a new collection of hot fill, wide mouth PET jars. This technology eliminates the need for panels. Foamed PET bottles: PTI devel- oped a blow moulding process, oPTI, for bottles with a solid core and a foamed outer layer. While the process- ing is much the same as for normal bottles, the preform manufacture is rather different. Here, the plasticis- ing unit is fitted with the MuCell gas injection process. Advantages are a 5% weight achievement and no need for additional light blockers (we report in issue 8). In issue 9, first field trials were taking place with Coca-Cola in Denmark. PDG plastique was featuring at PETpoint their PRElactia technology for UHT milk or light sensitive products with a 100% light barrier (issue 8). We reported in issue 9 about a 6.6 g water bottle which has been developed by Krones. Coca-Cola’s PlantBottle was men- tioned for the first time in PETplanet issue 10. 2010 Netstal featured in issue 4 its Prelactia solution: Double layer preforms are stretch-blow moulded to milk bottles whose inner skin is imper- vious to light, thus protecting the milk. Sidel claimed in issue 4 that its new Sky- ward and Curvy models were the lightest PET bottles available for hot filling. The 500ml bottles weighed 18.9 g each. Sidel Skyward Sipa said that it has been using its TriBloc technology to produce the world’s lightest 1,500ml water bottle, weighing 22 g. Siapi developed an automatic system, HandleMatic, for inserting han- dles on two-stage linear blowers, making it possible to insert the handle automati- cally in the mould (see issue 5). Called Deep Grip packaging, the technology enables significant grip depth but harnesses the advantages of ISBM instead of extrusion mould- ing. The technology has been jointly developed by PTI Europe, Sidel and Procter & Gamble and was presented in issue 10. Deep grip technology 2011 In issue 3 we reported on the frustration about SBM that it did not allow handles to be incorporated on the same line but had to be incor- porated manually. In a solution from Sipa for JRD in Dubai, the handles for their edible oil bottles have now been fitted automatically. Krones’ NitroHotFIll 15.5 was a new lightweight solution for hot filling up to 87 °C. The 500ml size weighed 15.5 g (issue 7+8). Using a Sipa technology, users of standard equipment could now produce large hot fill containers with PP handles. The separately moulded handle was inserted automatically into the containers between blowing and filling stages. The Smiler, an injection-moulded two-compartment PET container, has been developed by Emergent Tech- nologies and Plastic Technologies (PTI) and introduced in issue 11. The larger top compartment holds the liquid or a dry ingredient, while the bottom holds a snack item. 2012 Krones developed for the retailer Lidl a 1.5l PET bottle for highly carbonated water as announced in issue 1+2. With 26.8 g it turned out as the lightest CSD bottle to date. An update of Coca-Cola’s Plant Bottle initiative in issue 6: Since its intro- duction in 2009, the company has dis- tributed more than 10 million PlantBottle packages worldwide. The goal: to use PlantBottle packaging for the compa- ny’s entire virgin PET supply by 2020. Appe won two Liderpack Awards in Spain for their mineral water packag- ing (see issue 7+8). The 6.25 l bottle for Font Vella featured 25% rPET, and the 2.5 l bottle for aquaBona has been awarded for a lightweighting design. Sidel and Siapi were simultane- ously launching in issue 9 stackable solutions for PET bottles: Sidel’s concept Stack & Pack contained sizes from 250ml to 1 l; Siapi’s stackable containers Stack Lock contained capacities of 10, 16 and 20 l. In Issue 10, BTC Concept unveiled stackable and lockable BottleClips for 500ml packs. Inotech Kunststofftechnik GmbH developed a technology to produce multi-component preforms for SBM. It enables bottles with individual colour and material combinations without additional assembly steps (issue 9). R&D/Leverage helped a visionary entrepreneur to launch a new wine packaging concept in PET. The tear- apart stack of single-serve packages is being filled with premium Califor- nian wine, as reported in issue 11. Single-serve wine packages in PET Graham Packaging had launched a 24 oz jar for sauces (see issue 12).
