Sidel’s New Bottle Bottom Technology


The new StarLite Nitro non-petal bottle bottom with a unique shape, can significantly enhance the bottom stability and resistance. This also means that the new bottle bottom can improve the hardness of PET bottles, the injection of nitrogen caused by the internal pressure, a stronger resistance to force, higher environmental adaptability; In addition, it makes packaging design unique and more aesthetic, but also to ensure the safety of built-in products. The StarLite Nitro Bottom holds all the advantages of the Sidel StarLite Bottom, which was introduced in 2013 for the production of bottled beverages and carbonated beverages, and got the award of“Good environment for sustainable innovation ” in 2013 Global Bottled Water Awards.

Ensure strength, improve quality and supply chain stability:
Sidel’s StarLite Nitro Bottles enhance the quality of the bottles while guaranteeing the strength of the packaging, as well as improving the stability of the bottle throughout the supply chain. Through this technology, manufacturers can improve the bottle in a variety of production environment, anti-deformation performance. Vincent Le Guen, vice president of packaging design and molds at Sidel, said: “This design bottle bottom area, good stability, coupled with other structural design elements bottle, making the PET bottle into the internal pressure, (Depending on the bottom wall thickness). “This is particularly advantageous for products that are produced at high latitudes and then sold at low latitudes, and particular benefit, and the stability of the bottle during transport. Suitable for very high temperature applications. The new bottoms are developed by Sidel’s packaging specialists and tested using a variety of computer simulation techniques and also under physical testing in real conditions to ensure optimum performance throughout the supply chain.


Reduce the amount of raw materials, reduce bottle weight, reduce energy consumption:
Like the previous Sidel StarLite series, the new “Nitro” version of the production of PET bottle. By reducing the thickness of the bottle wall to achieve an excellent strength – weight ratio, reducing the blowing stage of energy consumption, reduce the weight, thereby reducing production costs. Vincent Le Guen continues: “For those beverage manufacturers who seek to reduce their total cost of ownership (TCO) to stay ahead in a competitive market and still achieve better sustainability, this solution “The new Sidel StarLite Nitro Bottom ensures the integrity of the packaging and enables the end product packaging to appeal to the consumer’s eye.” For example, a StarLite Nitro bottle of 0.5 liter PET bottles, bottles The bottom weighs only 1.8 grams and can withstand internal pressures up to 1 bar (depending on the design of the preform and the bottle, and the PET resin grade used).


Flexible and attractive:
Sidel’s new StarLite Nitro Bottom provides a flexible and attractive solution that supports the use of existing PET bottle designs and nitrogen injection processes to produce beverages, even without nitrogen injection. It is suitable for conventional filling, ultra-clean filling and aseptic filling. Nitro uses a design similar to that used in the production of non-aerated beverages to avoid confusion in supermarkets with bottles of petal bottoms, which are commonly used in carbonated soft drinks in the eyes of consumers. The new bottom can be used for 0.2 liter to 2.0 liter bottles. It adapts to Sidel’s various speed blow molding machines, including the latest Sidel Matrix ™ blow molding machines.

Improve supply chain performance:
StarLite Nitro Bottles enhance the stability and resistance of the bottles, enabling the bottles to perform better throughout the supply chain, even in harsh environments. These bottles are easy to transport (from filling, labeling to packaging) – optimize trouble-free running times and minimize downtime. In addition, bottles with new bottoms have better extreme temperature tolerance. At a storage temperature of 50 ° C or less, the bottle can withstand 25 days without deformation, and may be stored for longer periods of time. In addition, under frozen conditions, the bottle bottom can be reduced by 50%.

Really reduce costs and achieve sustainable production:
Sidel’s new StarLite Nitro Bottom has the potential for significant weight savings and significant cost savings. For example, at an annual production of 5,000 hours, 2200 per hour 0.5 liter PET bottles, each bottle is only a weight loss to calculate the annual cost savings of € 396,000 . According to the same calculation, 1.5-liter bottle weight loss of 1.8 grams, the annual cost savings of € 713,000. [1] The new bottle has a wider set of parameters (“process window”), and still can achieve the desired blow molding effect, so more than the existing bottle blowing easier. With this bottom technology, the air pressure requirement can be reduced by up to 25%. For example, for a 0.5-liter or 1.0-liter bottle, an ordinary bottle requires 25 bar of air pressure, and the new bottom needs only 18 to 20 bar. This can save more energy and save up to € 90,000 per year.
