As part of the new package, Emirates will continue with naming rights on the Gunners' 60,000-seater stadium at Ashburton Grove until 2028.
The ?30million-a-year contract represents a significant increase in additional revenue for the Barclays Premier League club.
Arsenal chief executive Ivan Gazidis believes the move shows the Gunners' intent to "keep at the top of the game in England and Europe".
He said in a statement ahead of Friday morning's press conference at Emirates Stadium: "This agreement is a testimony to Arsenal's approach and to the capabilities we have developed in recent years as well as the strength of our partnership with Emirates.
"The original deal with Emirates was a key facilitator of our move from Highbury and this next phase of our relationship will be just as critical to keep us at the top of the game in England and Europe.
"The fact this partnership will continue for many years to come underlines how much both organisations value and benefit from the relationship."
Chairman and chief executive of Emirates Airline and Group, His Highness Sheikh Ahmed bin Saeed Al Maktoum, added: "Arsenal's strong appeal around the globe and ambitious approach to the game parallel our own approach to business, making them a valuable partner for our brand."
