The international application for the invention (sent to the World Intellectual Property Organization, WIPO, in June 2012 and published globally in December 2013) describes a method that includes the use of an internal plastic liner for a barrier.
Although it is unclear what applications the soft drinks giant might have in mind, carbonates are clearly problematic – other ‘paper bottles’ on the market cater for wine, juice and milk.
A 'step forward' for sustainability and the environment
Told about PepsiCo’s paper bottle patent filing this morning CPS International director Andrew Streeter, a packaging expert, told BeverageDaily.com: “The way you describe it, it sounds new.
“I would have thought that for CSDs it wouldn’t be good enough for three atmospheres (atm), but may work for partially carbonated drinks – draft beer for instance,” he added.
“I haven’t seen the patent but it sounds like a good step forward for sustainability and the environment generally – it’s an obvious material to use,” Streeter said.
PepsiCo’s patent filing notes that recent efforts have been made to form bottles from a fibrous pulp, such as a cellulosic pulp of the type commonly used to make paper products.
“Such bottles provide potential for a significant reduction in the consumption of plastics used for making bottles, and since they can potentially be manufactured using recycled paper – pulp-molded bottles may be more environmentally friendly as well,” the firm’s filing states.
