When the product is fine, dusty or moisture-sensitive, the woven bag alone is not enough. A fitted PE liner keeps powder in and humidity out — tubular, form-fit or glued, with anti-static and food-grade variants.

Every field below is produced to your order. We confirm the exact combination before manufacturing.
U-panel, circular, 4-panel or baffle — liner added to any of them.
Tubular hangs loose; form-fit tailors to the bag shape.
Bonded to fabric, no slip during handling.
Thicker for fine or abrasive powders.
Fill opening matched to your equipment.
Controlled discharge with liner outlet.
Type C conductive liner for flammable dust.
Hygienic liner for food-contact use.
A liner is a separate film placed inside the FIBC. It stops fine powder leaking through the weave, blocks humidity, and keeps the product hygienic. The right fit and thickness depend on how fine, abrasive or moist the product is.

Each application sets different leak, moisture and hygiene needs — we match the liner to the product.

Flour, milk powder, sugar — liner + dust-minimising fill.

Fine or hygroscopic powders needing sealed containment.

Traceable, clean-lined bags for sensitive ingredients.
The bag body is built first; the liner is then inserted and sealed to match the fill and discharge openings.
