摘要： PROBLEM TO BE SOLVED: To provide a polyethylene resin laminated foam having a beautiful general appearance and being excellent in rigidity, cushioning properties and freeze resistance and also easy to recycle, and to provide the polyethylene resin laminated foam. SOLUTION: A resin melt for forming a resin layer which is constituted of a polyethylene resin composition and a resin melt for forming a foam layer which is constituted of the polyethylene resin composition are introduced into a ring die and co-extruded therefrom to form a tubular laminated foam wherein the resin layer is laminated at least on one side of the foam layer. In succession, the inside of the tubular laminated foam is cooled down by passing it along the peripheral surface of a cooling device and the foam is cut open in the direction of extrusion. Consequently, the laminated foam wherein the 30-300 μm thick resin layer is laminated at least on one side of the 1 mm or more thick foam layer is manufactured. In this method, the storage elastic modulus (E') at 100°C of the polyethylene resin composition forming the resin melt for forming the resin layer is 1.5 × 10 7 - 50.0 × 10 7 Pa.

摘要： PURPOSE: To reduce the warpage of plate-shaped foam and to prevent the damage of closed cells of a fused part by specifying the thickness, density and water absorption of foam using a non-crosslinked propylene resin with drawdown properties of a specific value or less as a base resin. CONSTITUTION: A foaming agent and, if necessary, various additives are added to a resin within an extruder and the resulting mixture is melted and kneaded under a high temp. and high pressure condition to form a foamable compsn. which is, in turn, extruded from the annular die 2 provided to the leading end of the extruder 1 under pressure lower than the pressure in the extruder and foamed to form cylindrical foam 3. Next, the cylindrical foam 3 is pressed by pinch rolls 4 to fuse the inner surface of the foam to mold plate-shaped foam 5. At this time, a non-crosslinked propylene resin with drawdown properties of 60m/min or less is used as a base resin. When foam with a thickness of 2-15mm, density of 0.06-0.3g/cm and water absorption of 1.0vol.% or less is used, the warpage of the plate-shaped foam can be suppressed to 10mm or less.
