B+K CleanFlex® Bottle-shaped bags

B+K CleanFlex® Bottle-shaped bags

We have been producing B+K CleanFlex® bottle-shaped bags for a number of years, with constantly growing experience and increasing improvements. For example, special sealing radii and cut-and-finish seams have led to important development steps.

With their sealed, shaped shoulder, these bags are used wherever compatibility with a filling or pouring spout has to be guaranteed to achieve dust-free filling/emptying. One additional advantage is the optimal, complete emptying ensured by the diagonal seals around the neck. This is highly-regarded, particularly when handling powdered, highly-sensitive and expensive products.

The bottle-shaped bags therefore offer ideal adaptability, in isolator production for example, whilst simultaneously providing high capacity in a compact format.
