The pilot was said to have requested permission to land at Arlanda, where he parked the plane at the end of the landing strip away from the terminals.
The Swedish authorities said that they had taken the threat seriously and had explosives experts on hand.
Reports from Pakistan identified the plane involved as Pakistan International Airlines flight PK782 travelling from Calgary via Toronto.
Two-hundred-and-forty-three passengers were said to be on the flight.
PIA spokesman Syed Sultan Hassan told the Reuters news agency that all passengers and crew members were well.
"Our central control is in touch with the plane and Stockholm but as far as security checks are concerned they're saying they are not going to tell us until they complete the process," he said.
Police said that everyone on the plane had passed through security in Canada.
