The new positioning comes a year after Sealed Air's £4.3bn acquisition of hygiene giant Diversey in October 2011 and aims to bring the benefits of both sides of the business into a single coherent approach to food and drink packaging.
The merger has created a business with turnover of more than $8bn and more than 26,000 employees across 62 countries.
Sealed Air's new approach will cover hygiene on the farm for livestock and extend right through the food supply chain to the consumer.
Sealed Air said that the new offering was the result of extensive consumer research, which identified food safety, shelf life extension, operational efficiency, sustainability and brand building as the key business drivers.
Moreno Dezio, divisional president for Sealed Air Europe, said: "Two leaders in packaging and hygiene respectively have joined forces and are proving their huge capacity to make a measurable difference to the entire food production process and we are starting to see the benefits of this.
"Working with leading processors, retailers and foodservice customers, teamed with our extensive consumer research, enables us to focus our resources and capabilities on what really matters to our customers."
