Ian Proudfoot, global head of agribusiness for KPMG, told a webinar the desire for health and hygiene could easily trump environmental worries about plastics.
His comments follow a steady pushback against plastics overseas and in New Zealand, where it led to a banon single use plastic bags in many parts of the economy with the aim of reducing pollution and reliance on fossil fuels, which are a raw ingredient for many plastics.
Proudfoot warned however that people could easily come to view plastic-packaged foodstuffs as clean and safe and could start to insist on it, leading to a revival in the use of plastics.
Proudfoot said the use of biodegradable plastics may offer a solution, and New Zealand could help to manufacture them.
"We produce a lot of trees, we produce wool, we produce fibre products and we produce a whole heap of biomass from the products that we grow, that is at present fundamentally a waste-stream."
Proudfoot said those materials could be used to create biodegradable packaging and help both the environment and the New Zealand economy.
