Product Description
When your product cannot tolerate any exposure to moisture, oxygen, light, or odour contamination, standard PE liners are not enough. Our Aluminium Foil Liner (PE/AL) is the highest level of barrier protection available for FIBC bags — engineered from multi-layer laminate film combining an outer PE sealing layer, a central aluminium foil barrier, and in some constructions an additional PET or nylon layer for mechanical strength.
This multi-layer construction blocks moisture vapour, oxygen ingress, ultraviolet light, and odour transfer almost completely — protecting premium food ingredients, pharmaceutical intermediates, and moisture-critical chemical additives across long shipping routes and extended storage periods. Where the cost of product degradation outweighs the cost of packaging, PE/AL liners deliver protection that no single-layer plastic liner can match.
Why Choose This Liner?
- Near-complete barrier against moisture vapour, oxygen, UV light, and odour transfer
- Multi-layer laminate (PE + aluminium foil + optional PET/nylon) provides superior mechanical strength alongside barrier performance
- Form-fit construction enhances filling, discharge, and overall bag handling stability
- Eliminates dusting and leakage — critical for fine, high-value powders
- Food contact approved and antistatic/conductive variants available for combustible powder applications
Typical Applications Industries
- Premium food ingredients sensitive to oxidation: coffee, cocoa, dairy powders, specialty fats
- Pharmaceutical intermediates and moisture-sensitive APIs
- Hygroscopic chemical additives and catalysts
- Electronic-grade materials sensitive to humidity and static
- Products requiring extended shelf life during long-distance sea freight

Frequently Asked Questions
Q1: How much better is a foil liner compared to a standard PE liner for moisture protection?
Aluminium foil liners achieve moisture vapour transmission rates that are typically 50-100 times lower than standard PE film of comparable thickness. For products where even trace moisture causes quality degradation — such as hygroscopic chemicals or premium food powders — this difference is the deciding factor between product integrity and spoilage over a multi-week shipping journey.
Q2: Can aluminium foil liners be heat-sealed for a fully airtight closure?
Yes. The PE outer layer of our foil liners is heat-sealable, allowing a fully closed, tamper-evident package. This is particularly valuable for high-value pharmaceutical intermediates or premium food ingredients where airtight integrity must be verifiable at the point of opening.
Q3: Are foil liners suitable for combustible powders requiring static protection?
Yes — we offer antistatic and conductive variants of our PE/AL foil liners (commonly referred to as L1/L2 liners) for use with Type C and Type B FIBC bags handling combustible powders. Specify your FIBC type classification when requesting a quote so we supply the correctly rated liner.
Q4: What is the typical cost difference between foil liners and standard PE liners?
Foil liners typically cost 2-4 times more than standard PE tube liners due to the multi-layer laminate construction. For products where moisture or oxygen exposure causes significant quality loss or shelf-life reduction, this investment is usually justified by reduced product loss and extended shelf life. We can provide a cost-benefit comparison based on your specific product and shipping route.
