Valve Sacks
Valve sacks from Feldmann: Filled quickly. Sealed automatically.
When filling operations need to be fast, valve sacks are the only way to go. The principle is simple but highly efficient: the sack is placed onto the machine nozzle via the integrated valve.
At Feldmann Verpackungen, we design valve sacks that match your products and machine capacities exactly. Whether classic paper valve sacks or robust material combinations with plastic barriers: we ensure that your bulk material is filled cleanly and arrives safely at your customer.

Where our valve sacks are used
Our valve sacks made from paper and paper-plastic combinations prove their performance daily in highly sensitive and demanding industries.
Food Industry
The strictest hygiene requirements apply here. We produce under clean conditions, use certified low-migration materials, and ensure dust-tight closures to prevent contamination.
Ideal for packaging
Flour, sugar, starch, baking mixes, milk powder, cocoa powder
Chemical Industry
Fine powders or chemical granulates often react sensitively to humidity or tend to produce dust. Our valve sacks with integrated barrier film remain sealed and protect both the product and the environment.
Perfectly suited for
Plastic granulates, color pigments, chemical powders, fertilizers
Building Materials Industry
When filling heavy construction materials, air must escape quickly from the sack without tearing the paper or releasing dust. Our paper valve sacks for the construction materials industry are tear-resistant and optimally vented thanks to precise microperforation.
The perfect packaging solution for
Cement, tile adhesive, plaster, joint mortar
Feed industry
Agricultural logistics can be rough. Our sacks are highly mechanically resilient and reliably protect feed from moisture and spoilage during storage.
Ideal for packaging
Pet food, mineral feed, seeds
