Liner Bags
PP Woven Liner Bags Manufacturer in India
Woven sacks with an inner LDPE or HM-HDPE liner for leak-proof, moisture-sealed bulk packaging.
About Liner Bags
A liner bag pairs the structural strength of a woven polypropylene sack with a separate polyethylene liner inside it. The woven outer carries the load; the inner liner forms a continuous barrier that stops fine powders escaping through the weave and stops moisture getting in. This two-layer construction is the standard answer for hygroscopic products and anything that must arrive dry.
Why Choose Our Liner Bags
Leak-Proof Containment
The inner liner holds fine powders and granules that would otherwise sift through a woven structure.
Moisture Barrier
A continuous polyethylene layer protects hygroscopic contents through storage and transit.
Contamination Protection
Contents never touch the outer sack, keeping the product clean and isolated from handling.
Loose or Fixed Liners
Liners can be supplied loose or tacked in place depending on how you fill and discharge the bag.

Frequently Asked Questions
What liner materials are used?
LDPE and HM-HDPE liners are both available. The choice depends on the barrier level and liner strength your product needs.
Are liner bags suitable for food products?
Yes. Specify food-grade at the enquiry stage and bags are produced from virgin polypropylene with a suitable liner for food contact.
Can the liner be fixed inside the bag?
Liners can be supplied loose or tacked to the outer sack. Tacked liners suit automated filling lines; loose liners are easier to remove on discharge.
