Abstract: A compressed coreless rolled product is described, including an inner surface defining a central cavity having an inner diameter and an outer surface having an outer diameter larger than the inner diameter. The outer diameter is at least five inches and a ratio of the inner diameter to the outer diameter is at least 0.35. Also described is a compressed coreless rolled product with similar inner and outer surfaces, wherein: a difference between the outer diameter and the inner diameter defining a thickness of at least 2.9 inches; and a ratio of the inner diameter to the outer diameter is at least 0.35. An associated method of producing the product is also described, including steps of: winding an absorbent sheet around a forming core member; removing the forming core member to form a coreless rolled product with a diameter ratio of at least 0.35; and compressing the product.

Abstract: A compressed hollow coreless roll of absorbent paper sheet produced by way of providing a roll of absorbent paper sheet by winding the sheet about a forming core member having a diameter in the range of 30 mm to 50 mm; removing the forming core member such that there is provided a hollow coreless roll of absorbent paper sheet with an axial cavity having a diameter in the range of 30 mm to 50 mm and compressing the hollow coreless roll such that, the axial cavity is substantially collapsed. The compressed hollow coreless rolls are readily re-formed into cylindrical shape. Space-saving packages of the rolls are overwrapped with tubular polymer film to provide a flexible reconfigurable package of a series of individually encased rolls. Volume reductions of about 10 to about 20%, about 14% to about 20%, 30%, 40% and more as compared with conventional products are realized.
