Description du produit
Notre Sacs de revêtement à fond rond en papier d'aluminium are expertly engineered for superior barrier performance. They work perfectly with drums, barrels, pails, and FIBC containers.
These liner bags feature a seamless round bottom construction. This design ensures a snug, wrinkle-free fit inside cylindrical containers. Par conséquent, waste is minimized, and filling and emptying become easier.
The manufacturing process welds a circular piece of aluminum foil to an open-ended foil tube. This creates a leak-proof seal – strong enough for liquids. You don’t need to worry about leaks or punctures.
We construct these liners with multi-layer aluminum foil composites (such as PET/AL/PA/PE). They offer outstanding resistance against:
-
Moisture
-
Oxygène
-
lumière UV
-
Other environmental factors that can degrade sensitive products
Additionally, these liners:
-
Protect against odor ingress or emission
-
Extend the life of your reusable containers
-
Help prevent corrosion
