There have been major moves under way to improve bottle design. Triggered by huge price hikes for plastics last year, the first trend features thin-walling, which is also a green improvement. A process refinement enabled a 19 percent weight reduction, saving over three million pounds of plastic annually in a Kraft salad dressing bottle. The optimized bottle design increased shipping efficiencies by 18 percent by allowing a greater number of bottles shipped per truckload. There has been an explosion in bottle thin walling in the past 18 months.
There has also been a huge improvement in the use of recycled PET in bottles. One of the leaders is Coca-Cola, which is developing a joint venture plant in South Carolina to produce food-grade recyclate. Capacity of the plant will be one billion pounds/yr, with half of the capacity being used by Coke and other half sold to external blow molders. Virtually all of the raw materials will be coming from municipal recycling programs. Coca-Cola Co. said it will boost recycled content of its PET bottles to 10 percent by the end of 2010 and 25 percent by 2015. Coke had reached 10 percent recycled content in North America in 2004 and 2005, but the level slipped to 3 percent or less. Coke’s wants to keep recycled material cost neutral with virgin PET. There is so much demand now for recycled PET that there actually is a shortage of supply.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
