Gas exchange is ensured by a specially developed fleece applied to XINXIA Seal

Gas exchange is ensured by a specially developed fleece applied to XINXIA Seal. Gases are fed in through the porous structure of the fleece via the cap thread, before being discharged into the atmosphere. The use of a special designed cap is not necessary.

Vent liner is used with agrochemicals, household cleaners and food supplements.

Vent liner provides a bidirectional gas exchange through a liquid-tight but gas-permeable membrane. This effectively prevents any "shrinkage" or “panelling” of the container due to a vacuum or excessive overpressure.
