About Petoskey Plastics

What started in 1969 as a small family operation in a northern Michigan pole barn has grown into one of North America's most respected polyethylene film and bag manufacturers. Petoskey Plastics was founded by Duke and Paul Keiswetter, and by April 1970 the company was officially in production with five employees and a single bag machine. More than five decades later, the company employs and supports over 450 families across multiple manufacturing facilities in Michigan, Tennessee, and Indiana — and remains proudly family-owned and privately held.

From the very beginning, Petoskey Plastics distinguished itself through a commitment to engineering and innovation. The company adopted in-house film extrusion in 1975 and launched its own recycling program as early as 1978 — well ahead of the industry curve. Today, that pioneering sustainability mindset is baked into every product line. Many Petoskey Plastics products can be manufactured with up to 70% third-party certified post-consumer recycled plastic, exceeding EPA recycled content requirements, and the company processes over 30 million pounds of recycled plastic annually at its Hartford City, Indiana facility.

The Slip-N-Grip® Automotive Line

In the automotive world, Petoskey Plastics is best known for its Slip-N-Grip® brand — a comprehensive suite of vehicle protection and service essentials trusted by dealerships, service centers, and automotive professionals across the country. Being headquartered in Michigan, the heart of the American automotive industry, made this a natural fit. The Slip-N-Grip® lineup covers everything a service bay needs to protect a customer's vehicle from the moment it pulls in to the moment it drives out.

The brand's tire bags are a staple for tire shops and service departments, keeping dirty or seasonal tires contained and away from clean vehicle interiors. For protecting flooring during service, Petoskey Plastics offers both plastic and paper floor mats — available in custom printed versions for dealerships looking to reinforce their brand with every visit. Steering wheel covers round out the cockpit protection offering, keeping grease and grime off a customer's wheel during service work. For body shops and paint prep environments, Petoskey Plastics' masking tape and paper products — part of the Steelcoat® line — deliver the painter's plastic and masking film performance that professionals demand. Completing the vehicle protection suite, disposable and recyclable seat covers help shops keep upholstery spotless while a vehicle is in their care.

Built on Sustainability and American Manufacturing

Petoskey Plastics' vertically integrated manufacturing process — which includes in-house extrusion, converting, printing, and recycling — gives the company tight control over quality and sustainability at every step. Their proprietary multi-layer 3- and 5-layer film technology allows engineers to custom-blend formulations that optimize performance while maximizing recycled content. For automotive shops, fleets, and service departments that want to reduce their environmental footprint without compromising on product performance, Petoskey Plastics offers a compelling and proven choice.
