Liners are inner protective layers made from Polyethylene (PE) material, designed to be used inside FIBCs and Woven Sacks to provide an additional barrier against moisture, dust, and contamination. For FIBCs, Multi-layer liners are commonly used to provide superior strength and enhanced barrier properties, while Mono-layer liners are typically preferred for Woven Sacks.
They act as an almost impermeable layer, helping prevent leakage, reduce product loss, and protect sensitive materials during storage and transportation. PE liners enhance the performance and service life of woven bags and FIBCs by shielding the fabric from abrasion, punctures, and internal wear caused by fine powders, granules, or abrasive contents. They are especially suitable for hygroscopic, fine, hazardous, or contamination-sensitive materials where maintaining product integrity is critical. Liners can be supplied pre-inserted into the bag, in roll form, or as cut pieces, depending on customer requirements and filling operations.

Applications of Liners
- Enhanced Protection – Provides an additional barrier against moisture, air, water vapor, and light exposure, ensuring product integrity.
- Product Safety – Protects sensitive materials from contamination and environmental factors.
- Versatility – Suitable for a wide range of applications, including food, chemicals, pharmaceuticals, and construction materials.
- Customizable Options – Available in various types (Loose, Glued, Tabbed, Stitched) and materials (LDPE, LLDPE & HDPE).
- Improved Material Retention – Reduces the risk of leakage for fine powders, liquids, and granular products.
- Static Control – Conductive and antistatic liners minimize risks in static-sensitive or flammable environments.
- Maintained Shape and Stability – Baffle/ Gambo liners help the bag retain its form during filling and transportation.
- Cost-Effective Solution – Reduces product loss and ensures safe transportation, minimizing operational costs.
- Compliance and Safety – Meets industry standards for hygiene, especially in food-grade and pharmaceutical applications.
