| titleOfInvention | Extrusion molding method for polyolefin resin multilayer foam sheet |
| abstract | Kind Code: A1 In extrusion foam lamination molding in which a polypropylene foam resin and a non-foamed polyolefin resin containing a filler are laminated, bubbles in the foam sheet are made fine, the open cell ratio is suppressed, and various physical properties and container molding are performed. A highly efficient polyolefin-based resin foam laminate sheet is produced with high production efficiency. A molten polypropylene resin (A) containing a foaming gas and a molten polyolefin resin (B) containing a filler are melt-kneaded in separate extruders and laminated through a junction to form a molding die. In the method of producing a laminated foam sheet by supplying to the die outlet and discharging from the die outlet, the expansion ratio (X) of the foamable gas-containing molten polypropylene resin (A) is 1.5 to 6 times, and When the thickness (L) is L1 for the foam layer of the foamable gas-containing polypropylene resin (A) and L2 for the filler-containing polyolefin resin layer (B), the relationship of L ≦ L1 / X + L2 is established. The manufacturing method of the laminated foam sheet which fills. [Selection figure] None |
