Tekni-Plex plans to close its north-side Milwaukee manufacturing facility, with property vacancy expected by June 2026

Facility closure set to leave large industrial site vacant on Milwaukee’s northwest side

Tekni-Plex is moving toward closing its manufacturing facility on Milwaukee’s north side, a shift that would leave a major industrial property vacant in mid-2026. The facility is located at 6161 N. 64th St., in the city’s 53218 ZIP code, a corridor that includes a mix of industrial operations and neighborhood-serving businesses.

Commercial marketing materials for the property list the building as a single-tenant manufacturing site of roughly 186,835 square feet on about 21 acres, and state that occupancy is expected to end in late spring 2026, with availability beginning in early June 2026. The listing also describes the site’s heavy industrial utility capacity and loading infrastructure, positioning it for continued manufacturing or warehousing use once it is vacated.

How the Milwaukee site fits into Tekni-Plex’s broader Wisconsin footprint

Tekni-Plex is a packaging and materials-science manufacturer with major operations serving healthcare and consumer-product markets. The company has expanded its healthcare packaging presence in Wisconsin over time, including operations in both the Milwaukee and Madison areas.

In 2019, Tekni-Plex completed the acquisition of a group of healthcare packaging plants that included locations in Milwaukee and Madison, bringing specialized production tied to sterile medical packaging substrates. More recently, TekniPlex Healthcare opened a new 200,000-square-foot facility in Madison in 2025 that it described as a flagship site for its barrier protection systems business.

What is confirmed, and what remains unclear

• The north-side Milwaukee facility at 6161 N. 64th St. is being positioned to become vacant around late May 2026, with availability in early June 2026.

• The building is being marketed for sale or lease as a large, single-tenant industrial property.

• Publicly available materials reviewed for this report do not specify the number of employees affected, the timing of production wind-down, or whether operations will be consolidated to other facilities.

Commercial property listings indicate the site’s occupancy is expected to end in late spring 2026, with availability starting in early June.

Local economic implications

Large industrial departures can have uneven impacts on surrounding neighborhoods: they may reduce on-site employment while also creating opportunities for reuse if new tenants move quickly. The 6161 N. 64th St. building’s size and specialized infrastructure suggest it could attract manufacturers or logistics users, though backfilling a single-tenant property at this scale often depends on broader industrial demand and financing conditions.

Milwaukee.news will continue to seek details on workforce impacts, closure timelines, and any plans for future use of the site.
