The Town of Bassendean has banned the "scourge" of single-use plastics from events organised or sponsored by the council.

That includes plastic straws, cups, plates and cutlery.

The town's mayor will also write to supermarket Coles asking it to stop using plastic wrapping, particularly on fruit and vegetables.

The ban will take effect immediately, but vendors who supply the council will be given six months to find alternatives to single-use plastic.

Councillor Sarah Quinton, who put forward the motion, told ABC Radio Perth cheap alternatives were readily available, such as 3 cent paper straws and cutlery, and 4 cent cardboard dishes.

"Even if vendors choose to put those costs on top of the cost of their food, it's still minimal, it's still probably 30 or 40 cents on top of the meal," Councillor Quinton said.

"And I think that's probably affordable when they're going out to some of our events in Bassendean."

The motion was passed six votes to one, in recognition of "the scourge that single use plastics has on our environment".

The dissenting councillor unsuccessfully argued for a community consultation period.

Vendors have not yet been informed of the move.

No fines for non-compliant vendors

Councillor Quinton said after the six-month grace period, vendors who used single-use plastics would be advised of the ban and provided with a list of alternatives.

"This is about behavioural and cultural change within our town," she said.

"We feel calling it a ban shows the seriousness we want to give it. But we're not going to police it in a way that we're going to issue fines."

The council will write to all businesses in the area outlining the ban and encouraging them to reduce single use plastics, "particularly straws and plastic cups where possible".

Mayor Renee McLennan will also write to Coles requesting "they audit and cease their use of plastic wrapping, particularly on fruit and vegetables".

"Our fruit and vegies, like bananas, are wrapped in plastic. Bananas are already wrapped," Councillor Quinton said.

Some produce needs packaging: Coles

"However, there are times when packaging is required to protect the product's freshness and to ensure food safety from farm to home," the spokesman said.

"For some produce, packaging reduces the incidence of defects such as bruising, crushing and dehydration, resulting in less waste within our stores and for our customers."

The Greens and the Conservation Council of WA want further action against single-use plastics, calling for all plastic balloons and straws as well as microbeads to be banned across the state.

Environment Minister Stephen Dawson has left open the idea of a wider plastics ban if there is wide community support.

Single-use plastic bags will be banned across the state from July 1.
