Valve Sacks
Valve sacks feature an integrated valve opening that allows powdery or free-flowing products to be filled quickly and cleanly. After filling, the valve closes automatically depending on the design or is additionally sealed. This makes valve sacks particularly suitable for automated filling processes, for example for building materials, food products or chemical products.

Cross-Bottom Sacks
Cross-bottom sacks are characterised by their stable, cross-folded base. This makes them easy to fill, securely close and store in a space-saving way. Depending on the design, they are suitable for a wide range of filling goods – from food and animal feed to building materials and seed.

Pinch Top sacks
Pinch Top sacks feature offset paper plies at the opening, which makes filling and subsequent closing much easier. They are particularly well-suited for powdery or free-flowing products and can be securely sealed by gluing.

FAQ

Can this bag type be processed on our fully automated pinch filling systems?

Yes. The bags are specially designed for machine processing. During production, we ensure precise cuts, correct adhesive bonding, and high dimensional accuracy of the empty packaging. This ensures trouble-free separation and error-free sealing on automated systems.
