Anode powder does not fail visibly — it fails as a number on a test report six weeks later. Water vapour and oxygen are the two routes in, and a PE liner only slows them down. This 800×800×600 bag carries an integrated aluminium foil composite liner that blocks moisture, oxygen and light, so the material arrives with the same moisture content it left with.

The build we use for graphite and silicon-carbon anode powders. Barrier grade, liner sealing and static type are the three fields that get agreed before anything is woven.

| Packaging | Bale or pallet, wrapped | Kept sealed until filling |
Anode materials differ in density, sensitivity and the way they are filled. These are the settings we agree first.
0.10–0.15 mm. Thicker foil for longer transit or humid destinations.
Matched to your filling head; a poor seal wastes the whole barrier.
Allows filling and purging before the liner is closed.
Other low-profile sizes to fit your filling head and pallet.
If the filling room is a classified dust zone, the bag changes type — not just the liner.
Conductive laminate for Type C service, bonded to ground. See L1 / L1C / L2 / L3.
Dedicated line area, bag turned and inspected before baling.
Water-vapour transmission and seal integrity on request.
A foil laminate has excellent barrier figures in a lab. In the field, the failure is almost never the foil — it is the seal, a crease, or a puncture from handling.

Anywhere the moisture or oxygen spec is tighter than a normal PE liner can hold.

Natural and synthetic graphite; moisture-sensitive at ppm level.

Carbon black and CNT powders — barrier plus static control.

Same barrier logic for hygroscopic chemicals and food ingredients.
The liner is integrated at sewing, so the bag and the barrier are one unit by the time it reaches your line.

Foil liner insertion is the step that decides whether the barrier survives to the customer.
Heavy PP fabric for puncture resistance.
Cut to 800×800×600; low-ink print.
Laminate cut, inserted and fixed without creasing the barrier.
Bag sewn with liner in place; seal checked.
Seal integrity, cleanliness and bale condition.

A foil laminate that is folded sharply during insertion will fail at the fold, no matter how good the film is. We insert and fix the liner with the bag opened flat, then inspect the seal and the fold lines before baling — the same reason we keep this work in-house.
