Product Description
Adding an inner liner to your Type A FIBC bag transforms a standard bulk container into a moisture-proof, dust-tight, and contamination-resistant packaging solution — without the cost of a specialised bag construction.
Our Type A FIBC Bag with Liner is available with three liner types to suit different product sensitivities: standard PE tube liners, form-fit PE liners, and foil (PE/AL) liners for maximum barrier performance. All liners are fitted and sealed at our factory, ready to fill on arrival.
Why Choose This Bag?
- Prevents moisture ingress for hygroscopic materials like salt, sugar, and silica
- Dust-tight barrier stops fine particles from escaping through woven fabric
- Form-fit liners conform to the bag shape for even filling and clean discharge
- Foil liners provide oxygen and UV barriers for sensitive or light-sensitive materials
- Factory-fitted liners eliminate on-site liner handling and reduce filling-line downtime
Typical Applications Industries
- Salt, sugar, and hygroscopic food powders
- Silica gel, zeolites, and desiccant materials
- Calcium carbonate, talc, and fine mineral powders
- Polymer masterbatch and colour concentrates
- Any product requiring moisture or oxygen barrier protection

Frequently Asked Questions
Q1: What is the difference between a tube liner and a form-fit liner?
A tube liner is a simple cylindrical sleeve — low cost and effective for general moisture protection. A form-fit liner is shaped to match the bag’s interior dimensions, giving better filling uniformity and cleaner discharge with less residue.
Q2: Do liners affect the filling or discharge process?
No — our liners are designed for standard spout-top filling and bottom-discharge equipment. The liner spout aligns with the bag spout for seamless integration with your filling line.
Q3: Can I specify the liner thickness?
Yes. We offer PE liners from 80 to 200 microns. Thicker liners provide greater puncture resistance for sharp or angular products. Our team will recommend the right gauge for your application.
Q4: Are foil liners available for food-grade applications?
Yes. Our PE/AL foil liners are available in food-contact grades. Combined with a food-grade bag body, this provides a complete food-safe solution for moisture and oxygen-sensitive ingredients.
