Protective Closures

MM Plastic (Mfg) Co. Inc. is a specialist in injection molding with extensive experience manufacturing protective closures. We work with a broad selection of materials, so we can provide closures made from the ideal plastic for your application. Our product portfolio consists of more than 700 different items, and we often perform custom design and molding services. We are dedicated to providing only products of the highest quality combined with personalized customer service. Our years of experience and team of dedicated professionals help us consistently meet that goal. We have been in operation since 1962.

Protective closures

The closures we produce for our customers are designed for creating a protective seal on openings such as tube ends. They are often used for shipping and storage applications, as they provide a barrier that keeps any contents secure and protected from contamination or damage. Many closures are built with custom features including colour, hinged lids, special shapes, and more.

Some if the plastics we regularly use include styrene, PVC, nylon, glass-filled nylon, polycarbonate, polyethylene, polypropylene. In addition we can work with a number of different thermoplastic rubbers. This diverse material selection enables us to offer solutions that are ideally suited to your environment and requirements.
