The polyolefin resin foam sheet is a polyolefin resin foam sheet having a plurality of cells in an inside thereof, wherein the 50% compressive strength is 120 kPa or less; the MD elongation percentage is 400% or less; and the TD elongation percentage is 200% or less.

Polyolefin resin foamed sheet and adhesive tape

A shock-absorbing sheet comprises a foamed resin layer having a thickness of 200 &#x3bc;m or less, a void ratio (P) of a plane directional cross section at a thickness of 0.1 T, a void ratio (P) of a plane directional cross section at a thickness of 0.5 T, and a void ratio (P) of a plane directional cross section at a thickness of 0.9 T from one surface of the foamed resin layer each ranging from 10 to 70 area %; and the standard deviation (P&#x3c3;) for an average void ratio found from the void ratio (P), the void ratio (P) and the void ratio (P) ranging from 1.0 to 20.

Shock-absorbing sheet

There is provided a polyolefin resin foam sheet having a plurality of cells which is formed by foaming a polyolefin resin, wherein, in the polyolefin resin foam sheet, the average cell sizes and the maximum cell sizes in the MD direction and the TD direction are each a predetermined value, and a ratio [TD strength at break/MD average cell size] and a ratio [MD strength at break/TD average cell size] are both 80 kPa/&#x3bc;m or more.

Polyolefin resin foam sheet and adhesive tape

There is provided a polyolefin resin foam sheet having a plurality of cells which is formed by foaming a polyolefin resin composition, wherein the polyolefin resin composition contains a polyolefin resin (A) having relatively high density and a polyolefin resin (B) having relatively low density, and the weighted average resin density of the polyolefin resin (A) and the polyolefin resin (B) is 0.900 g/cmor less; and wherein a ratio [TD strength at break/MD maximum cell size] and a ratio [MD strength at break/TD maximum cell size] are both 45 kPa/&#x3bc;m or more.
