PROBLEM TO BE SOLVED: To provide a polyolefinic foamed film superior in an infrared cutting-off capacity and surface strength. SOLUTION: The laminated polyolefinic foamed film contains a foamed layer (A), a surface layer (C) and the intermediate layer (B) provided between them. A filler is added to the foamed layer (A), and the average value of infrared reflectivity (%R) in a range of 700-2,000 nm by a spectrophotometer is 70% or above. COPYRIGHT: (C)2008,JPO&INPIT
