The Kraft drum is an open-top cardboard packaging solution, a precise assembly of a round drum body, with a bottom and a lid. To produce a cardboard drum, Abzac always starts with a cylinder produced by straight winding of several lengths of Kraft or a drum liner.

It is glued between the layers with mineral adhesive, eliminating any risk of mould.

Abzac also produces a completely waterproof model, where the adhesive is replaced with a reactivated polyethylene film. This process also offers improved rigidity.

Once the tube has been produced, two assembly techniques are used to obtain two families of drums:

• The crimped Kraft drum: this is the traditional model and the one most commonly used worldwide. The cardboard bottom is crimped with a metal ring.
• The all-fibre drum: meets demand to reduce or eliminate metal parts. The cardboard base is glued on.

Based on a certain number of standard diameters, any capacity can be created by adjusting the height.

The tube can be lined with a wide variety of more or less sophisticated linings, which are capable of providing an effective barrier for direct packaging of increasingly aggressive products. (see options section)
