This latest development aims to help Sainsbury’s cut its total packaging by a third by 2015.
According to the supermarket giant, the new jars “are just as functional as the previous ones”, and the reduced weight means not only do they have a lower environmental impact, they also require less fuel to transport.
Sainsbury’s head of packaging Stuart Lendrum said: “We have the most ambitious packaging reduction in the industry and meeting it will require hundreds of initiatives such as this.
“Our work on peanut butter is a great example of how you can reduce packaging without sacrificing its effectiveness. In fact, the new jars will be less prone to breaking making them even better than the previous ones.
“Excess packaging is one of the top concerns among customers, so it is a real priority for us. It is vital that we strike the correct balance between ensuring packaging is functional and reducing the volume we use.”

Sainsbury’s said that it had cut its packaging levels by 12m kilos over the past year, meaning around 7% of packaging has been removed from Sainsbury’s own-brand products through new packaging design. According to the supermarket, this equates to an 11% reduction over the past two years.
