Paktainer has in its offer liners with round seals. This kind of liner is mainly used for drums with a volume of 200–220 litres. Thanks to their circular seal, round liners are watertight. Drum liners can also be used for vacuum packaging or modified atmosphere packaging (with nitrogen or CO2). For this purpose, a special valve is sealed to the top of the liner.
Drum liners and other flat bottom liners can be used for foodstuffs and chemical products in the form of liquids, pastes, granulates and powders. Thanks to special laminates, high temperature materials can also be packed, i.e. hot melts.
Drum Liners can be made of PE, multilayer films based on EVOH or aluminium laminates.
