Descripción del Producto
Nuestro Bolsas con revestimiento de fondo redondo de papel de aluminio are expertly engineered for superior barrier performance. They work perfectly with drums, barriles, pails, y contenedores FIBC.
These liner bags feature a seamless round bottom construction. This design ensures a snug, wrinkle-free fit inside cylindrical containers. Como resultado, 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 (como PET/AL/PA/PE). They offer outstanding resistance against:
-
Humedad
-
Oxígeno
-
luz ultravioleta
-
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
