While bans on single use plastic bags have been welcomed by green groups and many shoppers, research by Canstar Blue shows 20 per cent don't agree.

Canstar says more than half of shoppers have already begun stockpiling plastic bags at home, based on a survey of more than 2200 people.

While 71 per cent of those surveyed back the ban, 21 per cent disagree and eight per cent are undecided.

Nearly half expect that taking their own bags to the shops would be a hassle.

"While the plastic bag ban is supported by most, the supermarkets can expect some frustrated customers in the weeks ahead," Canstar Blue Editor Simon Downes said on Monday.

National Plastic Bag Campaign co-founder Jon Dee has some tips to help shoppers adjust.
