| titleOfInvention | Polypropylene resin foam sheet, laminated foam sheet using the same, molded container therefrom, and method for producing the foam sheet |
| abstract | PROBLEM TO BE SOLVED: To provide a foamed polypropylene resin sheet excellent in formability and secondary workability, a foamed polypropylene resin sheet obtained by laminating a non-foamed polypropylene resin layer on the foamed sheet, and a foamed sheet thereof. Provided is a molded container obtained by heat molding a sheet. SOLUTION: The average thickness is 1 to 5 mm, the value obtained by dividing the difference between the maximum value and the minimum value of the thickness by the average thickness is 0.20 or less, the closed cell ratio is 60% or more, and the density is 0.1 or less. ~ 0.5g / cc Wherein the number of air bubbles per unit area is 30 / mm 2 or more, and the number of cycles of a periodically thin portion seen in the width direction of the sheet is 30 / m 2. The above-mentioned foamed polypropylene resin sheet, a foamed polypropylene resin sheet in which a polypropylene resin non-foamed layer is laminated on at least one side of the foamed sheet, a side obtained by thermoforming the foamed sheet or the laminated foamed sheet, The difference between the maximum value and the minimum value of the part thickness is 0.5 mm or less. |
