"What we need is timelines to force innovation, so if we have something to work towards, we can then work towards it. So it's great to see that leadership," Ms Johnson said.
From June this year, major supermarket chains will stop handing out single-use plastic bags.
Environment groups are now turning their attention to packaging, calling on supermarket brands to set an example by avoiding plastic in their own lines.
"As you'll see when you walk down the aisles, a lot of the products are their own brands so they can actually influence how those are packaged," Ms Johnson said.
She cited potato-based wrapping as an alternative.
"There are all sorts of starch-based plastics available so they look like plastic and they feel like plastic, they've got a slightly sticky feel at the moment, the film is certainly available at the moment," Ms Johnson said.
The paper industry also says plastic-free aisles easily achievable with sustainable fibre packaged products on the shelves.
"They can do all the things that plastic has ever done and much, much more - like for example showing if they've been tampered with or showing if the temperature has changed in the packaging," Australian Forest Products Association CEO Ross Hampton said.
Supermarkets silent on plastic-free aisle proposal
Supermarket chains did not comment directly on the idea of plastic-free aisles.
Instead Woolworths says it is trialling reducing plastic packaging for 28 fresh fruit and vegetable lines with an aim to remove 150 tonnes per year.
Coles says it is actively working with suppliers on more sustainable options.
As for its own water bottles, they were made out of recycled plastic.
Meanwhile ALDI said it was using recyclable plastic crates to display fresh produce, soft drinks and vegetable oil.
Recycling more effective
While some concentrate on eliminating plastics, recycling company Replas wants to get its hands on more.
The Victorian company turns 60 tonnes of soft plastics like shopping bags and frozen food packs each week into park benches and bollards.
Replas Victorian territory manager Kelvin Agg says banning types of plastic from supermarket shelves is not the answer to the global waste problem.
"We'll ban one substance or material and another one's created and used. So as far as consumption, it makes more sense to work out a way to turn all this waste into a resource," he told SBS News.
Replas hopes to increase the amount saved from landfill but its plans are limited by the demand for the end result.
