<p>PURPOSE:To form the titled mat in an integral body having a water-absorbing property inside a vessel and a water-proof property outside the vessel, by putting and hot-pressing the surface of a water-absorbing cloth sheet through a polyethylene layer onto a water-proof cloth sheet, e.g. polystyrene. CONSTITUTION:A water-absorbing cloth sheet 3, e.g. water-absorbing paper, is introduced along the direction of a hot-press roller 7 at the receiving part of a laminate machine, while a polyethylene film 4 is introduced from the center. A water- proof cloth sheet 2, e.g. a polystyrene sheet, is then introduced along the direction of a roll 6. The polyethylene film 2 at the center is melted by a heat supplied from the hot-press roller 7 and laminated and hot-pressed onto the sheet, 3, 4 to obtain a water-proof wrapping mat 1. EFFECT:The wrapping mat, which enables very easy wrapping work, suitable for massproduction can be offered at a low cost. USE:For wrapping edible and processed marine products.</p> |
