Shares of the company, which distributes products ranging from disposable tableware to latex gloves and cleaning chemicals to private and government sectors, rose about 6% to a record high of 2,710 pence to be perched at the top of the FTSE 100 index.
Bunzl said group revenue for the third quarter was up 4% at actual exchange rates and 8.8% at constant exchange rates.
"The 2020 performance year to date has been driven by strong sales of COVID-19 related products, from a combination of smaller orders and the more exceptional larger orders," the company said in a trading statement.
Bunzl resumed dividends in August as it reported first-half profit and revenue that surpassed analysts' expectations.
