Foil Laminate FIBC Liners for Barrier-Sensitive Powders
For a barrier-sensitive powder, specify the barrier requirement and how the liner will be installed. Relia’s catalog lists foil laminate liner constructions. Film results are useful when the test conditions match your use. A finished liner also needs a separate check of folds, seam continuity, closure and fit inside the woven shell.

Barrier Targets by Material and Test Condition
State which exposure matters during storage and transport. Give your target values or test method and the measurement conditions QA uses to compare samples.
Manufacturing checks for this specification
Relia’s catalog lists PE and multilayer liner options incorporating materials such as aluminum foil, PET or nylon. For the exact offer, ask for the layer sequence, product-facing material, thickness tolerance and seal arrangement. Verify where the seams and folds land when the liner is installed, especially near the inlet and outlet.
- 01Define the laminate
- 02Specify neck and seals
- 03Check assembled fit
State the barrier target, test conditions and the storage or transport exposure. Compare film data under the same temperature and humidity where relevant. On the installed sample, check neck engagement, fold interference, seam integrity and closure. A hazardous-material application needs separate approval of the entire packaging and operating configuration.
Relia factory process and quality checks
Separate film-barrier evidence from the sealed liner
Specify the laminate stack, thickness and seam construction. For a moisture-sensitive powder, request the water-vapor transmission result with its test method, temperature and humidity. If oxygen exposure matters, specify that target separately.
Set sample checks for fold damage, seal continuity and installed fit. Use your outer bag drawing and filling-head interface for the trial. Film data describes the material tested, while leaks at folds or seams need assembly-level review.
A Complete Film and Seam Schedule
Identify the proposed layers, film thickness and seam format. Request evidence that distinguishes the film result from the performance of a sealed liner.
A Neck That Fits the Filling Head
Send the inlet diameter or flat width, engagement length and closing method. Mark the outlet if the liner must also fit a discharge station.
Folds and Fit Inside the Woven Bag
Show the available space and expected filled shape. Check where folds contact corners, ports and seams when the liner is installed.
Sealed Samples for the Trial
Agree how samples are sealed, packed and evaluated with your powder and route. Retain the result alongside the proposed film and seam schedule.
Storage and Handling of Empty Liners
Set the fold and protection requirements with the receiving team. Check the sample for damage at handling points and seal areas before releasing the order.
Receiving controls for a barrier liner
Ask how empty liners will be folded, bundled and protected from creasing or contact damage before fitting. Keep the layers and seam layout in the purchase specification, then define how to inspect a sample from each delivery. Where foil is part of the laminate, examine fold locations from the shipping pack and after installation rather than evaluating the flat film alone.
Documentation for Special Materials
Share the material safety information and destination if the powder has special handling or contact requirements. Review compatibility and applicable documentation for the whole assembly.
Evidence to keep with the order
Keep film or laminate data separate from a sample seam result. The same laminate can be fabricated with different seams and closures. Request the test conditions, the tested specimen, and a sample marked to the exact layer and seam schedule.
Related Liner Selection
Use the liner guide to compare candidate geometries and the requirements guide to scope any separate contact or electrostatic review.
