The blister disk 56 on the side wraps the electrode coil 52 in place through the PVC film layer 53 to prevent it from spreading. Baffles are set at both ends of the electrode coil 52, and a plastic tube 55 is arranged on the outer side, so that during the packaging process, external collision will not affect the internal coil, especially when an inner aluminum foil bag is set on the outer side of the subsequent packaging and the inner aluminum foil bag is vacuumed, the blister disk 56 and the plastic tube 55 at the outermost ends can well protect the internal electrode coil and avoid extrusion and collision caused by the compression of the vacuum space.

When the lower lining 41 and the upper lining 42 are connected, the lower surface of the upper lining 42 and the upper surface of the lower lining 41 are plugged into each other through the positioning protrusions and the positioning grooves.
