Shoppers around the country are planning to leave their unwanted plastic packaging at their local supermarket today.
The 'Shop and Drop' day of action against supermarket packaging is being organised by the Sick of Plastic campaign.
More than 400 volunteers have registered to promote the action at stores across the country.
In response Repak said its members are committed to a sustainable future and have helped recycle over one million tonnes of plastic packaging since 1997.
The agency said its members are increasing recyclable and reusable packaging in their stores and reducing the amount of plastic by removing excess packaging on products throughout the supply chain and increasing the use of reusable packaging such as pallets, crates and trays.
It also said they are also changing materials so that they can be recycled
Repak said they are currently achieving a plastic recycling rate of 34%, which it said is well ahead of the current EU target of 22.5%
However, it said everybody must do more and Ireland must be more ambitious with its recycling in the future.
