What Petoskey Plastics makes

Petoskey Plastics is a vertically integrated blown-film manufacturer and plastics recycler. It extrudes 3- and 5-layer polyethylene film, blending LDPE and LLDPE for toughness with HDPE for tensile strength, then converts that film into bags and protective covers across eight markets. The company reports that 98% of the equipment across its four plants can run 3- and 5-layer technology. Its recycling operation closes the loop: post-consumer plastic is reprocessed into GreenPE resin, which goes back into the company's own products at levels up to 70% post-consumer content, a share the company says exceeds EPA recycled-content requirements.

The automotive line is the piece most relevant to vehicle programs. Petoskey supplies OEMs and tier suppliers with protective seat covers, slip-assist films, and noise-suppression silk films. The silk film wraps a seat frame to separate it from the foam, both to remove buzz, squeak, and rattle (BSR) noise and to ease assembly when the seat is built. Programs of this kind typically run through OEM quality gates such as PPAP. Under the Slip-N-Grip brand it also serves the automotive aftermarket, dealerships, and vehicle body-repair shops with seat covers, floor mats, service labels, and custom paint-and-body sheeting. Product families across the rest of the business include Grip N Guard construction film, Can Sacks and Pactor bags, Greencore institutional can liners, Steelcoat Medical barrier film and biohazard bags, and GreenPE Shrink film.

Ownership and history

Duke and Paul Keiswetter founded Petoskey Plastics in 1969, and operations began on April 1, 1970 with five employees and a single bag machine that converted purchased film into plastic bags. The company bought its first extrusion line to make film in 1975 and began in-house recycling in 1978. State of Michigan Quality of Life grants in 1990 and 1991 funded a recycle line and wash-line technology to reprocess post-consumer bags and film. In 1999 the company acquired a polyethylene film plant in Morristown, Tennessee, which now runs multiple 3- and 5-layer extrusion lines. Production has since expanded to a plant in McKinney, Texas as well.

The company remains privately held and family-owned. Paul Keiswetter, a U.S. Marine Corps veteran who led the business for roughly five decades, is Chairman and CEO; his son Jason Keiswetter was named President in early 2020 after several years of succession planning, having previously served as Executive Vice President. Petoskey Plastics has been recognized as a veteran-owned business, including Veteran Business of the Year honors in 2023 and 2025.

Locations and scale

Petoskey Plastics runs four manufacturing plants and describes six company locations in total. The Petoskey, Michigan plant handles extrusion, seat-cover lines, and Steelcoat Medical film; Hartford City, Indiana is the recycling and GreenPE resin site; Morristown, Tennessee runs multi-layer extrusion, converting, and a four-color offset print press; and McKinney, Texas runs blown-film lines. The corporate headquarters sits in downtown Petoskey, with a sales and marketing office in Birmingham, Michigan. The company reports roughly 500 associates, and a 2025 Traverse City Business News feature put the figure at nearly 600 across the plants, serving more than 6,000 customers in 45 countries.

Sustainability and recycling

Recycling is central to how Petoskey Plastics manufactures, not a side program. The company reports using 33,175,676 pounds of recycled plastic in 2025 and saving 27,149,698 kilograms of CO2e that year, with recycled resin making up 28% of the plastic it used. Its GreenPE post-consumer and post-industrial resins are produced at the Hartford City, Indiana facility, whose central location the company uses to serve major U.S. markets and feed recycled material back into its Michigan and Tennessee extrusion lines. Buyers weighing recycled-content requirements or nearshoring domestic supply will find an all-U.S. manufacturing footprint here.

Certifications and quality

Petoskey Plastics does not publish an ISO 9001 or IATF 16949 certificate on its site. It does cite specific regulatory and standards compliance: an FDA No Objection Letter for food-contact post-consumer LLDPE, medical barrier films that pass ASTM F1671 viral-penetration requirements, and biohazard bags meeting ASTM D1922 and D1709. Products are made domestically and marketed as Made in the USA. The company is a member of the Plastics Industry Association and a certified veteran business. Buyers who require a formal quality-management-system certificate for a given program should confirm scope directly, since none is posted publicly.

Sourcing evidence

Petoskey Plastics appears in U.S. customs bill-of-lading records as an importer, with 253 sea shipments on record and a most recent shipment dated July 18, 2026. For a domestic manufacturer this is an inbound record of raw materials, additives, and equipment inputs rather than finished goods bought for resale, consistent with a company that extrudes and converts its own film. The named foreign suppliers are concentrated in China and include plastics-product and medical-goods shippers such as Xian Tao Huafu Plastics Product and Shanghai-based trading firms.

These are U.S. ocean-freight records only. Air, truck, and rail movements do not appear, some records name freight intermediaries rather than manufacturers, and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence, and the customs footprint says nothing about the company's domestic production volumes, which are far larger than its imports.
