摘要

The crepe paper sheet (10) consists of at least one layer of crepe cellulose wadding with a weight of between 12 and 30 g/sq m and a corrugated design with at least one series of micro-protuberances (16) projecting from one side of the layer and having a density of over 20 micro-protuberances per sq cm. The micro-protuberances are made by a spiked roller; they have polyhedral bases and flattened tips (30) with rounded edges. The bases of the micro-protuberances can be in the form of rectangular bases of pyramids with sides angled at 35 - 45 degrees. Each micro- protuberance has an overall height of 0.05 - 0.5 mm and they are set in a density of 30 - 80 per sq cm. The sheet also has macro-protuberances with tips joined to an adjacent layer.
