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
