  • the thickness is preferably about 0.3 to 3 mm, more preferably about 0.5 to 2 mm.
  • the surface sheet 13 and the absorbent sheet body 11 can be bonded 14 by a method that can be appropriately selected by those skilled in the art, for example, bonding with an adhesive, thermal bonding, bonding with sonic, or the like.
  • the adhesive 14 is used for that purpose by opening 13 a of the top sheet 13, particularly on the side in contact with the absorbent sheet body 11 (the contact surface side with the absorbent sheet body 11) ) In the opening 12 (that is, the opening in the direction of B in FIG. 7), and the substantial opening ratio should not be changed before and after bonding.
  • the surface sheet 13 and the absorbent sheet body 11 are bonded to each other by spraying a 3.0 g / m 2 hot melt adhesive. At this time, if the hot melt adhesive is sprayed to a thickness of 0.3 mm or less, the opening 14 on the absorbent sheet body 11 side of the topsheet 13 is not completely blocked.

  • test piece was collected from the same piece of meat, and the chromaticity a value of the test piece immediately after cutting was measured. Next, a test piece is placed on each tray mat 10, and after 5 hours, 24 hours, 48 hours, 96 hours, and 144 hours have elapsed, the chromaticity a value on the tray mat 10 contact surface side of the test piece, Was measured.
  • the chromaticity a value was measured using a color difference meter (trade name “CR-300” manufactured by Minolta Co., Ltd.) in accordance with the D-0 method defined in JIS Z8722. During measurement, the measurement sample was illuminated from all directions, and reflected light in the vertical direction was received with respect to the measurement material. The measurement diameter was 8.0 mm, and the value of chromaticity a value in the red-green direction was taken.
  • the airflow resistance values of the thin films (films) having the aperture ratios shown in Table 1 were measured to be Examples 1 to 4, Comparative Example 1 and Comparative Example 2, respectively.
  • the deterioration of meat color when used as 13 was measured. The results are shown in Table 1.
  • the airflow resistance value was measured using an Automatic Air-Permeability Tester (product name “KES-F8-AP1”, manufactured by Kato Tech Co., Ltd.), and a constant flow rate of air flow to the tray mat 10 or the top sheet 13 was 4 cc / It was passed through at a rate of cm 2 ⁇ sec (area: 2 ⁇ ⁇ 10 ⁇ 4 m 2 ), and released and sucked. And the pressure loss of 3 seconds of exhaust and 3 seconds of intake was measured using the semiconductor differential pressure gauge, and the integral value was obtained.
  • KES-F8-AP1 Automatic Air-Permeability Tester
  • FIG. 15 shows changes in the chromaticity a value of Comparative Example 2 and changes in the chromaticity a value of Example 1. As is apparent from Table 1 and FIG. 15, when the tray mat 10 according to the present invention is used, a good state of meat color is maintained for a relatively long time.

Abstract

L'invention porte sur un matériau absorbant l'égouttement apte à empêcher la couleur d'un aliment, tel que de la viande, qui est disposé sur celui-ci, sur le côté qui est en contact avec celui-ci, d'être altérée. Un matériau absorbant l'égouttement (10), qui doit se trouver en dessous d'un aliment s'égouttant avec un fluide contenant du sang, comprend un élément en feuille absorbant (11) apte à absorber l'égouttement et un élément en feuille à surface poreuse (13) qui est situé sur l'élément en feuille absorbant (11) et qui vient en contact avec l'aliment, la perméabilité à l'air du matériau absorbant l'égouttement (10) étant améliorée aussi bien dans la direction de l'épaisseur que dans la direction du plan, de façon à empêcher ainsi la couleur de la viande, sur le côté qui est en contact avec le matériau absorbant l'égouttement (10), de s'altérer.
