What Is Contract Filling?

Contract Filling Services

Rather than handling filling processes within your business, contract filling is the outsourcing of filling operations to a company that specializes in those services. Contract filling services can be quite advantageous for product manufacturers that already have a developed product that needs packaging, eliminating costs your business would incur to purchase specialized filling equipment, and allowing experts to handle the filling so that you won’t have to.

At Case Mason, we capitalize on our consumer insights to help create attractive, cost-effective packaging solutions for well-known brands and startups alike. We offer manual and automated operations for scalable production runs to best suit your needs.

Bottle Filling

Our bottle filling capabilities allow us to work with both liquid and dry products for rapid filling of as many as 100 bottles each minute. For versatile packaging options, Case Mason is able to fill plastic and glass bottles, jars, and tins, finishing the process with heat induction, capping, and sealing.

Cosmetics Filling

Our cosmetic filling services include the capability to package granular (we don’t the right equipment for cosmetic granular filling, so that part can be removed. We can only fill industrial granular products) and liquid products in a range of fill sizes and container types. Our team works with both small startup brands as well as global cosmetic companies, customizing our filling processes to meet your production run needs.
