Sacks may be made of synthetic materials or laminates, for various weights. They may be filled through the valve, which then automatically seals itself, thus preventing any leakage.
The filled valve sack forms a block, by way of the standing base and valve, which is then very stable and stackable. The possibility to print the package on all sides provides ample space for product information.. Valve sacks with special ventilation options, by way of ultra fine perforations or labyrinth vents, are especially suitable for powdery contents.
Various applications offer our customers diverse options:
• Different valve forms (stepped fringe valve, exterior sleeve, internal sleeve valve, etc.)
• Pouring holes and aids
• Resealing options
