Our double-layer barley paper (also known as blue shell paper) insulation sheet is a high-performance flexible composite material, engineered for demanding insulation needs in electrical equipment and lithium battery packs. Composed of cyan electrical insulation wood pulp paper and polyester film, bonded by acid-free adhesive, this two-layer structure combines the excellent insulation properties of wood pulp paper with the superior dielectric strength of polyester film. Designed with optional single-sided adhesive and a standard thickness of 0.2mm, it delivers reliable mechanical and electrical performance, making it an ideal choice for 18650 battery packs, motor maintenance, transformers, and low-voltage electrical equipment.

This double-layer barley paper insulation sheet is widely used in low-voltage electrical equipment, lithium battery packs, and mechanical maintenance, including but not limited to:
Ideal for 18650 and other lithium battery packs – used as insulation gaskets between cells, sealing pads, or component separators to prevent short circuits and enhance battery safety.
Perfect for low-voltage motors and electrical appliances as slot insulation, gasket insulation, and inter-turn insulation; suitable for motor repair, transformer insulation protection, and enameled wire insulation wrapping.
Applied in electrical cabinets, electronic components, and automotive electronics as insulation spacers or gap-sealing materials, delivering reliable protection in various industrial scenarios.
