Rotogravure Printing
Your artwork is engraved on cylinders and printed in multiple colours on high-speed rotogravure presses. The result is sharp images, rich colour and the same registration from the first metre to the last.
Liner Bags for Sugar Industry
LD liner bags that go inside woven sugar sacks to keep sugar dry, clean and free-flowing.
Overview
What are Liner Bags for Sugar Industry?
Sugar picks up moisture very easily. In a plain woven sack it can absorb humidity, form lumps and get contaminated by dust. A liner bag is a thin plastic bag placed inside the woven sack that keeps the sugar sealed from moisture and dirt.
We make food-grade LD liner bags sized for standard 50 kg sugar sacks and for other sizes as required, supplied in bulk to sugar mills and packers.

Step 02
Lamination
The printed film is bonded with one or more layers such as PE, metallised PET or foil. Lamination adds strength, sealability and barrier against moisture, oxygen and light.
Step 03
Curing
Laminated rolls rest in a controlled curing area until the adhesive reaches full bond strength. This step is what keeps layers from separating later on your packing line.
Step 04
Slitting & Rewinding
Cured jumbo rolls are slit to the exact width and rewound on the core size your machine needs, ready for automatic form-fill-seal lines.
Step 05
Pouch & Bag Making
Rolls are converted into pouches and bags with side seal, bottom seal, centre seal, zipper, handle or gusset as required, then checked, packed and dispatched.
FAQ
Common questions
Why does sugar need a liner bag?
Sugar absorbs moisture from the air. A liner bag stops moisture getting in, so the sugar does not form lumps or spoil during storage.
What size liner do I need for a 50 kg sugar bag?
Share your woven sack size and we will make the liner to fit with the right allowance for filling and stitching.
Is the liner safe for food?
Yes. Our sugar liners are made from food-grade virgin LDPE.
