Title (EN) SHOCK-ABSORBING SHEET
(FR) FEUILLE ABSORBANT LES CHOCS
(JA) 衝撃吸収シート
Abstract:
(EN) The shock-absorbing sheet according to the present invention comprises a foam resin layer having a thickness (T) of 200 μm or less. The void ratio (P0.1) at thickness 0.1 T in a planar direction cross section, the void ratio (P0.5) at thickness 0.5 T in a planar direction cross section, and the void ratio (P0.9) at thickness 0.9 T in a planar direction cross section from one surface of the foam resin layer are each 10–70 area%. The standard deviation (Pσ) for the average void ratio determined from the void ratio (P0.1), the void ratio (P0.5), and the void ratio (P0.9) is 1.0–20.
(FR) L'invention concerne une feuille absorbant les chocs, comprenant une couche de résine en mousse dotée d'une épaisseur (T) de 200 µm ou inférieure. Le rapport de vide P0,1) à l'épaisseur 0,1 T dans une coupe transversale plane, le rapport de vide (P0,5) à une épaisseur de 0,5 T dans une coupe transversale plane et le rapport de vide (P0,9) à une épaisseur de 0,9 T dans une coupe transversale plane à partir d'une surface de la couche de résine en mousse représentent chacun de 10 à 70 % en surface. L'écart-type (Pσ) pour le rapport de vide moyen déterminé à partir du rapport de vide (P0,1), du rapport de vide (P0,5) et du rapport de vide (P0,9) étant de 1,0 à 20.
(JA) 厚み(T)が200μm以下の発泡樹脂層を含む衝撃吸収シートであって、前記発泡樹脂層の一方の面から、厚さ0.1Tにおける面方向断面の空隙率(P0.1)、厚さ0.5Tにおける面方向断面の空隙率(P0.5)、及び厚さ0.9Tにおける面方向断面の空隙率(P0.9)がそれぞれ、10~70面積%であり、前記空隙率(P0.1)、空隙率(P0.5)、及び空隙率(P0.9)から求めた平均空隙率に対する標準偏差(Pσ)が1.0~20である、衝撃吸収シートである。
