The Dukat ChemiSeal Vented™ liners are two-piece vented liners made of cardboard or PE foam and sealed by induction. They are inserted into the cap (they can be glued in or applied by friction fit), and then sealed on the edge of the container by induction. 

The Dukat ChemiSeal Vented™ liners are used to seal containers with liquids and solids and allow the transmission of gas.

Action: Gas passes through the membrane, spreads in the cardboard layer and escapes through the screw thread. A hole in the closure is not necessary.

Vented liners compensate the pressure inside the container and additionally prevent distortion. They allow the transmission of gas and provide a barrier for liquids at the same time. With these liners, the packing costs of certain products can significantly be reduced. 

Both professional and household cleaners often contain bleach, oxidants and other gaseous components that can exert pressure and get so great that the container “swells” or even bursts. Other products that contain surfactants, solvents or oil absorb oxygen and cause the collapse of containers. In addition, rapid changes of storage and transport conditions (such as temperature changes and elevation) contribute to processes mentioned above and result in deformation and, in extreme cases, in container damage.

It is expensive to prevent container collapse caused by pressure difference.  One way to prevent container collapse is to use thick walled containers.  Unfortunately, it is expensive because of large quantity of plastic needed to produce such containers.

On the other hand, it could be much more expensive if nothing is done to prevent container damager. Consequently, the company which products keep spilling during transportation, can lose its customers.

Vented liners are; in this case, an affordable solution to the problem of container distorting caused by internal pressure changes.

A specially designed membrane in the sealing liner as well as an appropriately selected cap help gas accumulated in the container and absorbed from the air to freely flow between the product and environment, whereas the liquid product remains safely sealed in the container. 

Benefits of using vented liners:

  • reduction of package weight,
  • reduction of complaints and returns,
  • preservation of container appearance required for store shelves,
  • positive product distinction in the market,
  • ensured integrity of the product.
