Individualization through additional equipment

Ventilation valve

After sealing the product, the air that has entered during filling is released via the welded-on valve. The packaging is now sealed airtight.

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.

PowFlex® ventilation

The patented PowFlex® ventilation system enables air to escape completely through a ventilation channel during the filling process.

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.
