Why does the vacuum hold-down matter?

Wrinkles in the sealing zone are the most common leak cause in liquid liners: two film layers are not properly welded there. The vacuum hold-down keeps the web flat and prevents the problem at source.

Which container sizes do the liners suit?

Geometry is specified per container. Send us the internal dimensions and the required valve type and we will clarify feasibility with the factory.

Are the liners food-contact compliant?

Yes, when certified films are used. The declaration of conformity comes from the film supplier and is provided per product.

DLP-600 Wasserbeutel / Stapelbehälter-Liner

DLP-600: water bags and stackable-container liners

The DLP-600 water bag machine produces 3D liners with valve for stackable containers and water transport bags. A vacuum hold-down keeps the film web flat during forming and prevents wrinkles in the sealing zone, the most common cause of leaks in large liquid liners.

What defines this machine

Vacuum hold-down against wrinkles

The film is held flat by suction during forming. Without it, wrinkles form in the sealing zone, exactly where large liquid liners leak.

Matched to stackable containers

Liner geometry follows the internal dimensions of common stackable containers, using the volume rather than trapping air in the corners.

Integrated valve

The discharge valve is placed and sealed on the same machine. No separate operation, no intermediate storage of open liners.

Compact 600 frame size

The 600 frame needs far less floor space than the large liner machines and suits plants with limited hall space.
