The news comes after SQF unveiled a pledge in February to ensure all its packaging is recyclable or compostable by 2022.
Black plastic is more difficult to recycle than white plastic and often uses specalist equipment.
Richard Oke, marketing manager at Sleaford Quality Foods, said: "It's pleasing to announce that we are in the process of removing ALL black plastic from our packaging range. White plastic is more environmentally friendly than black and can be more easily sorted for recycling by large machinery.”
"This reaffirms our commitment to sustainable working practices in response to increasing consumer and client demand for greener packaging products. We're committed to ensuring that SQF is at the cutting edge of sustainable packaging technology."
The first SQF products to benefit from the new, more sustainable packaging are the Chef William black tubs used for products such as gravy, soups, bouillons and salt.
The roll-out of white tubs will start in May, with customers scheduled to see new tubs in early June.
