The present invention provides for a process for transforming a substantially continuous web of substantially planar, deformable material having an indefinite length, a first surface, and a second surface into a formed material. The material has a transformation temperature range. The process comprises the following steps: (a) The web of material is provided on a forming structure with the first surface of the web of material proximate a forming surface of the forming structure. The forming surface moves in a direction of the length of the web of material and carries the web of material in that direction. (b) A liquid stream is applied to the second surface of the web of material. The liquid stream has sufficient force and mass flux to cause the web of material to be deformed toward the forming surface, such that the material acquires a substantial three-dimensional conformation. (c) The temperature of the web of material is controlled such that it remains below the transformation temperature range of the material throughout the process.
A debossed and perforated material comprising a polymeric film having a first surface and a second surface separated by a maximum thickness T, said material comprising a land area which has an upper surface which defines a plane and comprises a portion of said second surface of said film and a lower surface which comprises a portion of said first surface of said film, said film exhibiting a surface roughness on at least one of said upper and lower surfaces of said land area, said film comprising perforated protuberances, each of said protuberances comprising the following:
The debossed and perforated material of Claim 34 wherein said polymeric film is a thermoplastic film selected from the group consisting of polyethylenes and polypropylenes.
A debossed and perforated material comprising a polymeric film having a first surface and a second surface separated by a maximum thickness T, said material comprising a land area which has an upper surface which defines a plane and comprises a portion of said second surface of said film and a lower surface which comprises a portion of said first surface of said film, said film exhibiting a surface roughness on said lower surface of said land area, said film comprising perforated protuberances, each of said protuberances comprising the following:
A debossed and perforated material comprising a polymeric film having a first surface and a second surface separated by a maximum thickness T, said material comprising a land area which has an upper surface which defines a plane and comprises a portion of said second surface of said film and a lower surface which comprises a portion of said first surface of said film, said film comprising perforated protuberances, each of said protuberances comprising the following:
A debossed and perforated material comprising a polymeric film having a first surface and a second surface separated by a maximum thickness T, said material comprising a land area which has an upper surface which defines a plane and comprises a portion of said second surface of said film and a lower surface which comprises a portion of said first surface of said film, said film comprising perforated protuberances, each of said protuberances comprising the following:
