Three E waves

The thickness is about 1.5~2MM. Since the E wave is the thinnest among the four, it is not suitable for sending large items. E-wave core paper has a dense wave density, and the cardboard feels hard. Instead, it is a small and delicate object. It is mostly used in the inner packaging of electronic parts, small boutiques, cosmetics, etc. It is also often used in cake gift boxes or gift boxes.
