Weyerhaeuser Co. said it will let about 85 employees go as it closes down its Honolulu corrugated packaging facility.

Weyerhaeuser said it will provide job transition support to employees who will receive benefits in accordance with company policy and labor contracts.

The 50-year old operation is being closed to improve financial returns and enhance Weyerhaeuser's competitiveness, the company said. The shutdown is not related to performance issues of workers, it said.

"Weyerhaeuser has enjoyed serving customers for 50 years in Hawai'i, and it is with much regret that we announce the permanent closure of the Honolulu box plant," said Ed Carter, Weyerhaeuser Containerboard Packaging and Recycling sales vice president, in a press statement.

"We fully understand the significant impact of this decision on our employees, customers, suppliers and the community, and we will work constructively in the weeks ahead to alleviate these impacts as much as possible."
