Nestlé has given a clear indication that it sees the majority of its brands in future being packaged in conventional plastics made from renewable resources, not the first generation of bioplastics such as PLA and PHA.
In a video interview with news website FoodProductionDaily.com, Dr Anne Roulin, global head of packaging and design at Nestlé, says: “There's definitely still applications for PLA; it's a very interesting material. But the properties just don't fit the majority of our products.”
One of the properties needed in Nestlé packaging but not adequately provided by PLA is the provision of a moisture vapour barrier.
Roulin mentions Braskem's sugar cane-derived polyethylene as an example of conventional plastics which will be produced on a large scale from renewable resources.
Non-food crops, including cellulose, could form the basis for a later generation of renewable plastics, she says.
“I think it's going to be an evolution where we will continuously reduce environmental impact and find more energy efficient processes. But I really see the trend going in the direction of conventional plastics made from renewable resources.”
