Winner of the 2008 Best Packaging Innovation Award: Krones AG of Germany, in the "Best Packaging Innovation" award of the 2008 Water Packaging Innovation Awards organized by professional magazine "bottledwaterworld", weighs only 6.6 grams of 0.5-litre PET plastic bottle Received a gold medal. Krones' PET lite 6.6 research program has set a new milestone for the lightweight beverage bottled industry. Only 500 grams of purified water can be "packaged" using only 6.6 grams of PET material. This technical innovation on the one hand assigns bottles to different functional areas. The upper part of the bottle selects a smaller diameter to improve the stability of the user gripping the bottle. There is a special groove for additional reinforcement at the bottle catcher for easy empty bottle labeling. The diameter of the lower part of the bottle is significantly larger, and most of the purified water is concentrated here. Here the wall thickness is less than 0.1 mm. On the other hand, the bottle is stabilized with nitrogen so that it does not become weak during transportation and transportation. During the filling process, a small amount of liquid nitrogen is injected into the bottle, and the liquid nitrogen is vaporized after capping to ensure that the pressure in the bottle is about 0.5 Pa. With this internal pressure, it is safe to handle the bottle on the filling line and transport it on an ordinary tray. The bottle mouth (without the usual ring) developed by Krones and Bericap company weighs only 1.3 grams, and the cover also reached the unique 1.1 grams. The combination of bottle threads, closures, material mass distribution, design, and the use of liquid nitrogen all resulted in a bottle weighing only 6.6 grams.
