Fibre drums are cylindrical containers used for the transportation and storage of dry, semi-liquid and liquid products, ranging from 1 to 78 gallons. They play a crucial role in our portfolio by offering sustainable, versatile, and cost-effective packaging solutions. 

The current methods for the production of fibre drums utilize materials and processes that inherently generate particulate matter, which can enter the packaging (fibre drum) during manufacturing. 

Metal particulates can be introduced into fibre drum packaging from several mechanical forming processes: precurling/hemming, mechanical crimping, steel metering and welding. These processes are essential for manufacturing and attaching chimes - metal hoops or bands at the top and bottom edges of the drum - which provide structural reinforcement and maintain the drum's integrity. 

Precurling or hemming involves shaping the edges of the drum’s components to create a smooth, rounded edge, ensuring secure fitting with lids or closures. During this process, metal particulates can be generated from the tools and machinery used. 

Mechanical crimping, a process used to attach the chimes to the drum body, involves pressing or bending the metal to secure it tightly around the drum. This process also produces metal particulates from the crimping tools and the metal chimes themselves. 

Metering and welding are used to decoil and cut chime band materials and weld them to the final chime size. This process also produces metal particulates from the cut-to-length shearing, and potential slag from welding. 

If not properly managed, particulates generated in the processes described above can enter the interior of the fibre drum.
