Cross bottom valve sacks

Cleanly filled. Securely sealed: our cross bottom valve sacks can be conveniently filled via a valve that seals itself automatically on completion of the filling process. The product is therefore unable to escape and is reliably protected against external influences. Is the consistency of your products powdery? We ensure that your products are optimally ventilated by means of ultrafine perforations or labyrinth ventilation systems.

The filled valve sack takes on a block shape and is therefore particularly stable and easy to stack. Optional all-round printing offers sufficient space for your product information.

We manufacture our cross bottom valve sacks from plastics or laminates with variable specific weights, and also with a barrier function or using DuPont™ Tyvek® on request. Simply whatever best suits your application.

Individualization through additional equipment

DuPont™ Tyvek®

Versatile, durable, breathable: Tyvek® is a DuPont™ brand nonwoven material with a low dead weight and offers extremely high resistance to water, abrasion, the ingress of bacteria, and aging.

Carrying handle

Applied separately or punched in exactly where it is needed: a carrying handle offers increased comfort during transport and when using the product.

Easy peel

Opening packaging is simplicity itself: our easy peel films can be peeled-off effortlessly and without residues thanks to special recipes and coatings.

Various ventilation systems

For our optional ventilation systems, we process the packaging mechanically using defined perforations and cuts, thereby allowing the air to escape during the filling process.

Use of recyclate

By using recycled materials, we are making an important contribution to safeguarding resources and protecting the environment and the climate together with you.

Aluminum barrier

Longer shelf life: aluminum barriers in the laminate offer products effective protection against external influences such as UV radiation, water vapor, and oxygen.

Various barriers

Optimum protection for sensitive products: barriers that are effective against moisture, UV radiation, and oxygen can be produced using various materials in the laminate.
